Whittemore, J.
This information in equity to enforce a trust, brought by the Attorney General at the relation of members of the Association for the Arnold Arboretum, Inc., challenges the acts of the defendant under a resolution of January 19, 1953, in removing to Cambridge, from the Arnold Arboretum premises in the Jamaica Plain district of Boston, the bulk of the library and herbarium of the Arboretum. The basic issue is whether this removal was a breach of the trust under which the Arnold Arboretum was established and developed. The facts are found in a master’s report.
Interlocutory decrees were entered in the county court, denying the defendant’s motions in respect of the master’s [127]*127report, overruling its exceptions thereto and confirming the report. A reservation and report by the single justice1 presents these decrees for review as well as the substance of the final decree appropriately to be entered. The master’s report is well organized, clear, and complete, and we dispose of the case thereon.
The trust is set out in an Indenture dated March 29,1872, by which the trustees under the will of James B. Arnold of New Bedford gave to the President and Fellows of Harvard College (the Corporation) a fund that, by the will, was to be “applied for the promotion of Agricultural or Horticultural improvements, or other Philosophical or Philanthropic purposes.”
There were negotiations preliminary to the execution of the Indenture. George B. Emerson, one of James Arnold’s trustees, in a letter to the acting president of Harvard, in March, 1869, had stated his desire “if possible, to have an arboretum — and for Harvard College”; also, if land could be found near the college, to establish the arboretum in Cambridge as an appendage to the Botanic Garden. Emerson and the two other trustees, John J. Dixwell and Francis E. Parker, had been closely associated with Harvard.
The 1872 Indenture required that the Corporation should accumulate income until the principal should be $150,000 and until the Bussey land at West Roxbury (now Jamaica Plain) thereinafter described should come into the full and free possession of the Corporation and that thereafter the Corporation should devote ninety-five per cent of “the said nett income in every year, to the establishment and support of an Arboretum,2 to be called the Arnold Arboretum, which shall contain, as far as is practicable, all the trees, shrubs and herbaceous plants, either indigenous or exotic which can be raised in the open air at the said West Roxbury, . . . [128]*128and to the support of a Professor, to be called the Arnold Professor, who shall have the care and management of the said Arboretum, subject to the same control by the said President and Fellows to which the professors in the Bus-sey Institution are now subject, and who shall teach the knowledge of trees in the University which is in the charge of the said President and Fellows, and shall give such other instruction therein as may be naturally directly and usefully connected therewith.” The Indenture further provides : “And as the entire fund, increased by the accumulations above named, under the best management and with the greatest economy, is barely sufficient to accomplish the proposed object, it is expressly provided that it shall not be diminished by supplementing any other object, however meritorious, or kindred in its nature. But the said President and Fellows shall be allowed to obtain from said Arboretum, free of cost, any trees, shrubs, and herbaceous plants, which, in the judgment of the Arnold Professor, can be spared from said Arboretum, without injury thereto; the same to be used for the ornament of the college grounds, at Cambridge or elsewhere.” A following article provided that for “the purpose of ascertaining the said nett income, it is agreed that the fund shall be subject to no charge, except for actual expenses; and in the management of the said fund, it is to be charged only such a part of the actual expense of managing the property of the college, as the said fund bears to the entire property of the College.”
The Corporation by the 1872 Indenture agreed to dedicate exclusively to the purposes of the Arboretum about 137 acres of the land in West Roxbury (now Jamaica Plain) devised to it by Benjamin Bussey for the purpose, as declared in his will, of establishing there as the Bussey Institution a course of instruction in practical agriculture and subservient and connected arts.
The Corporation in due course after 1872 and in the decades following established and maintained the Arnold Arboretum with its physical embodiment, as intended, on the Bussey land in Jamaica Plain, and with related activi[129]*129ties centering in an administration building on the Arbore-grounds.
Charles Sprague Sargent was appointed Director of the Arnold Arboretum in 1873 and was elected Arnold Professor on June 30, 1879. He held these positions until his death in 1927. Oakes Ames and, after him, Elmer Drew Merrill followed Sargent as Arnold Professor, with the position vacant in 1927-1932, 1935-1936, and 1948-1954. Each of these Arnold Professors held other responsible positions in the administration of Harvard’s botanical collections. Sargent in 1879 pointed out to the Corporation the need for both a library and a reference collection of plant specimens. The Corporation promptly, and thereafter from time to time, made appropriations from the trust income for these purposes. The library and herbarium were located in a dwelling house in Brookline until 1892 and thereafter, until the removal to Cambridge in 1954, in the administration building at Jamaica Plain.
Under the guidance of Professors Sargent, Ames, and Merrill, there had been accumulated by 1946 approximately 6,500 species in the living collection, 630,000 sheets of specimens in the herbarium, and 46,000 bound volumes and 14,000 pamphlets in the library. By 1944, or earlier, the administration building had become overcrowded and presented a serious fire hazard.
The Arboretum under Sargent “had more or less followed a ‘policy of isolation.’ ” Professors Ames and Merrill, however, after 1927, departed from this policy by closer cooperation with other botanical departments. At the same time the scientific work of the Arboretum was broadened to include pathology, cytology, genetics, ecology, and other fields. As noted, the 1872 Indenture provided for the living collection to be raised at West Roxbury and the Arnold Professor to teach in the university and contained no other provision limiting the location of scientific work of the Arboretum. Members of the staff conducted explorations in North America, Europe, Africa, Australia, and Asia to bring back living plants and specimens. They used the [130]*130biological laboratories and Gray Herbarium in Cambridge for research and office space and taught courses in the Department of Biology at Cambridge. Research and experimental work were carried on at the Harvard Forest at Petersham and the Case Estates in Weston.3
The Arnold Arboretum, growing under able leadership, acquired many of the characteristics of an independent institution, and it came to be so regarded. It acquired high reputation and prestige. The Corporation received additional gifts and bequests as endowment funds for the purposes of the Arboretum. After 1927, the Corporation raised a fund of $1,000,000 as the Charles Sprague Sargent Memorial to add to the endowment.4
On January 19, 1953, after nine years of investigation, the Corporation adopted a statement of policy that included approval of the removal of the library and herbarium to Cambridge. This was pursuant to a plan to merge the library and herbarium with those of the Gray Herbarium. The statement declared that the Bailey Report of 1945, discussed below, should not apply to the Arboretum, and acknowledged that the property and endowment held for the purposes of the Arboretum were held by the Corporation in trust, and that “in the administration of the trust it is to act with a view to the best interests of the Arboretum.” The statement of policy concluded with the determination by the Corporation, as trustee of endowment funds held for the purposes of the Arboretum, “that it is in the best interests of the Arboretum and will promote the purposes of its endowment to remove to a central building in Cambridge [the new Harvard University Herbarium] the main body of the library and herbarium of the Arboretum related to research, and to retain at Jamaica Plain such books and [131]*131specimens as may be required to provide there a working library and herbarium. ’ ’ The transferred books and specimens were to be identified as a part of the Arboretum and remain under the care of the Arnold Professor. The Arnold Professor and the directors of the university library and the New York Botanical Garden were to determine the books and specimens to be retained at Jamaica Plain. A part of the expense of annual maintenance and operation of the central building was to be charged to the Arboretum endowment.
Scientific, administrative, and legal consideration of the removal to Cambridge began in 1944. In that year, Professor Irving Bailey, a member of the staff of the Arboretum, was requested by the Provost of the university to investigate “the total botanical situation” of the university. Professor Bailey submitted his report in 1945. It contained no consideration of the responsibilities of the Corporation as trustee under the 1872 Indenture. Emphasized were the isolation and wasteful duplication of the various botanical activities at Harvard.5 The proposed solution included the combination of all the botanical libraries and herbaria (as distinguished from the final action merging only those of the Arboretum and the Gray Herbarium and three other collections) in a central unit in Cambridge. Permeating the plan and its initial implementation was a concern for the overall needs of botany at Harvard.6
[132]*132From November, 1949, until January 19,1953, strong opposition by the Board of Overseers’ Committee to Visit the Arnold Arboretum, joined in by a member of the Corporation, directed the attention of those involved to the fact that a transfer of the library and herbarium must accord with the purposes of the Arboretum endowment.
In the course of the developing controversy those opposed to the move asked of the Corporation that the doubts be resolved by a legal proceeding. That the proposals were questioned by responsible persons dedicated to the welfare of the university and to the Arnold Arboretum strongly suggested, we think, the wisdom of following that course. With the benefit of hindsight it is now abundantly plain that the interests of all concerned would have been greatly served by so doing. The master found that the Corporation was determined not to seek a judicial determination of the issues involved because it believed its position legally sound, was hesitant to incur the very large expense involved and believed that some of the claims were on a moral level, which a legal decision would not dispose of.
On October 2, 1952, a resolution was drafted by counsel to the Corporation that, with certain changes, was to be approved by the Corporation as the resolution of Janu-uary 19, 1953. A revised draft of October 14, 1952,7 was approved by the Corporation in October. This draft resolution was, in substance, adopted by the Coordinating Committee on the Biological Sciences of the Board of Overseers and, on January 12, 1953, by the Overseers. The draft resolution was also submitted, in November, 1952, to representatives of the Visiting Committee, including counsel. [133]*133Counsel to the Visiting Committee responded on December 22, 1952, urging that the Corporation as trustee was obliged to act “with a view solely to the best interests of the Arboretum” and that there be no removal since serious doubts had been raised as to whether removal would be in the Arboretum’s best interests.
The master (under the heading of “The Motive Underlying the Adoption of the Resolution of January 19,1953”) found, inter alia, as folloAvs:
(1) The resolution was adopted by the Corporation in the belief that action under it would not constitute a breach of trust and would be consistent with its conception of its obligations as to the property held for the purposes of the Arnold Arboretum.
(2) The decision to move the main body of the library and herbarium was made “wholly or in major part” because of a belief that although such removal was consistent Avith the Corporation’s obligation Avith respect to the Arboretum assets “such removal would promote the science of botany as a whole at Harvard (rather than the interests of particular botanical institutions).”
(3) “The Corporation acted in the bona fide belief that it was entitled, and indeed had a duty, to consider the interests of botany as a whole at Harvard and the standing of the University in the botanical field. ’ ’
(4) “The conviction of the Corporation, reflected in its [earlier] approval of the Bailey Plan, that a transfer of libraries and herbaria to a new central building in Cambridge would promote the science of botany at Harvard from an overall standpoint (rather than from the standpoint of each component part), having been made after careful and serious deliberation, remained the controlling factor in the Corporation’s final determination to bring about the transfer of the main portion of the library and herbarium moved from Jamaica Plain.”
(5) The Corporation accepted as sound the view underlying the language of the report of the Coordinating Committee of the Board of Overseers in 1950 that the Arbore-[134]*134turn should be regarded as an instrument in the development of botany as a whole.8
(6) The Corporation believed that “if it were required to act solely in the interests of the Arnold Arboretum with respect to the removal ... it would be impossible to operate the University since the Corporation felt that it had to consider a great many different interests that were involved in the removal as well as the effect of the action on the University as a whole.”
(7) The Corporation refused to state in the January 19, 1953, resolution that it was acting solely in the interests of the Arboretum because it was aware that it was not so acting.
The master found as to the effect of the removal of the main portions of the library and the herbarium to Cambridge, as follows:
(1) The high reputation, prestige, and standing, which the Arnold Arboretum had enjoyed separate from that of the university, markedly declined. The books, other library items, and the specimens “are commonly looked upon as those of Harvard rather than as those of the Arboretum, and thus the prestige of the Arnold Arboretum’s library and herbarium has in effect been transferred to Harvard University, and the Arboretum has come to be looked upon as an appendage to the Botanic ‘Department’ at Harvard.”
(2) Unsatisfactory housing and working conditions in [135]*135the administration building at Jamaica Plain have been remedied. The library and the herbarium are now well housed in a fireproof air conditioned building in Cambridge. All this could have been accomplished, however, without the removal to Cambridge.
(3) Segregation at Jamaica Plain of a library and her-barium devoted to horticulture “might have enabled more efficient work at Jamaica Plain in horticulture and in the use of the living collections,” but this could have been accomplished without the removal of the bulk of the items to Cambridge. The evidence “does not warrant a conclusion that either the library or the herbarium at Jamaica Plain is reasonably adequate for horticultural or other work.”
(4) The move has been of advantage to carrying on taxonomic research in Cambridge because of “the vast number of the books, pamphlets, periodicals and specimens of the Gray and Arnold . . . combined together in one building with other botanical facilities and scholarly contacts at hand or nearby.” There is, however, a “marked disadvantage” to the carrying on of such research “arising from the separation of books and herbarium specimens from the living collections in Jamaica Plain, from the separation of the wild and cultivated specimen collections and from the division of the Arboretum staff resulting from the move.”
(5) The work performed by persons paid from Arboretum funds in taxonomy, horticulture and other scientific fields has continued. They are performing competent scientific work. There is no evidence of either improvement or decline in the quality of work.
(6) The services of the Arnold Professor have not been shown to have been diverted from the care and management of the Arboretum.
(7) The books and specimens of the Arboretum now in the Harvard University Herbarium are under the control of the Arnold professor. Use is made of them, as before, but to a greater extent, by Harvard students and faculty and others engaged in research. Each separate library item is identified as an Arnold Arboretum item, but not [136]*136in the card catalogue. A book housed at Cambridge if lost or misplaced cannot be identified from the catalogue as having been an Arboretum book. Each herbarium sheet from the Arboretum is so marked but the herbarium cases are not marked and one must examine each sheet to determine ownership.
(8) Since the removal, persons paid with Arboretum funds have performed the same type of activities as such persons performed earlier. These activities have been carried on in Jamaica Plain, Cambridge and Weston. The evidence does not establish either improvement or impairment in such work.
(9) “The removal of the main part of the library and herbarium of the Arnold Arboretum and the coupling of it with the Gray Herbarium and its library at the Harvard University Herbarium created one of the greatest libraries and herbaria in the world and a world famous scientific station identified with Harvard. Notwithstanding the effect of the removal on the Arnold Arboretum, the removal was in the interests of botany as a whole both in intent and effect, and the return of the Arboretum portion of the library and herbarium to Jamaica Plain would be a retrograde step from the standpoint of botany. A witness called by the petitioner testified that he considered such a step would create ‘a tremendous outcry from botanists throughout the country’ and would be unthinkable.”
The view that there has been a breach of trust is, we think, founded in the concept of an obligation to maintain the Arnold Arboretum as the particular institution that the combined efforts of the Corporation, professors, directors and staff in the use and application of the trust funds over the years had caused it to become.9 For reasons stated in [137]*137the following paragraphs we hold that such an obligation was not imposed by the 1872 Indenture.
The express intent of the 1872 Indenture is to benefit the public through the establishment and maintenance by Harvard University of an arboretum as described, and a professorship in the university as described. Certain other purposes are implicit. Obvious are the creation and maintenance of related libraries and herbaria and the conduct of directly related activities. This being a public charitable trust there are, we hold, other important implications to be found therein.
There is a dominant public interest that public charitable trusts in private educational hands be so managed under the particular trust provisions as to be of maximum usefulness, thus serving to the greatest possible extent the public as the ultimate beneficiary. In the light of this, in a gift to a university of trust funds to create a specific subdivision of scientific or cultural activity of the university (that is, broadly, a department10), there is, we think, an implied intention that the managers of the university shall determine in their best judgment what policies, in respect of that department, within the express trust purposes, will give that department and the trust assets used therein their greatest [138]*138usefulness. Certainly it is implied that to such end the managers may decide to correlate the activities of the department with the overall policies of related departments, provided all applicable restrictions are regarded, and the trust assets are used advantageously for the specific purposes of the trust.
These implications exist in respect of the trust under the 1872 Indenture. The advantages of having the Arboretum a part of the larger scientific and professional operation of Harvard University were, it appears, recognized by at least one of the donor trustees. See Harvard College v. Attorney Gen. 228 Mass. 396, 410. These implications are not negatived by the express requirement of the 1872 Indenture that the fund “not be diminished by supplementing any other object.” The use of the fund and its income for the purposes of the Indenture is not diminished in any degree. The Indenture, in expressly providing that the Arboretum as there described have its physical embodiment in West Roxbury (Jamaica Plain), specified a physical separation from other parts of the university in Cambridge. As described in the Indenture the Arboretum was a place for the growing of “trees, shrubs, and herbaceous plants.” The separation of this activity from Cambridge does not imply a requirement that the Arboretum be managed as though it were unrelated to an institution having other divisions with similar activities.
We agree with the relators that the Indenture did not give a fund to the Corporation to be used for general botanical purposes, nevertheless, the Corporation, in the course of determining what management of the assets of the Arboretum would reasonably and appropriately serve the direct purposes of the Indenture, was entitled to give consideration to the effect of the move on other departments and botany as a whole at Harvard and the possible general advantages to result. Such consideration cannot mean, however, that those other ends are to be regarded as purposes of the Indenture. Even in administering a private trust, the trustee may regard related matters. Penniman v. San-[139]*139derson, 13 Allen, 193, 205-206. The duty to consider the overall welfare of the university and the ultimate purposes of all its foundations of course did not disqualify the members of the Corporation in respect of the decision under the Indenture. Resolution of possibly divergent interests is inherent in the holding and management by a single institution of a number of public trusts for independent, related or overlapping purposes.
The members of the Corporation did not violate the “duty of loyalty” that required them to “administer the trust solely with a view to the accomplishment of the purposes of the trust and not with a view to promoting their own interests.” Scott, Trusts (2d ed.) § 379, p. 2735. Boston Safe Deposit & Trust Co. v. Lewis, 317 Mass. 137, 140. They did not act adversely to the trust and, in taking into consideration the effect on botany as a whole, they were regardful of an end which, as we have held, was within the general implied purposes of the public trust so far as in support of the specific purposes. The members of the Corporation rightly declined to accept the view that they were required “to act solely in the interests of the Arnold arboretum.” The implication of a determination to this effect would have been to exclude relevant and appropriate considerations.
The plain obligation of the members of the Corporation was to bring to bear the attention and judgment required of trustees in the performance of their trust duties on the issue of the effect of the move on the continued accomplishment of the express purposes of the trust and to act in a way that they believed in their good judgment would promote those purposes. We hold that the findings show that they did so act.
The subsidiary facts support the master’s conclusions that the challenged move stemmed from the Bailey report and that the promotion of the science of botany at Harvard from an overall standpoint was the controlling factor. This conclusion, however, does not in itself imply a finding that the members of the Corporation failed to give consid[140]*140eration to the effect of the move on the accomplishment of the trust purposes, or failed adequately to weigh evidence relevant thereto.
The members of the Corporation acted in the light of an opinion from their counsel. This advised that the transfer might lawfully be carried out “provided, (i) that the removal be justified as promoting the purposes of the Arboretum, (ii) that such books and specimens 'as are required to provide a working library and herbarium at Jamaica Plain should be retained there’ and (iii) that any additional annual operating costs chargeable to the Arboretum be justified upon a determination by the Corporation of the extent to which the Arboretum purposes would be benefited by the move, having regard to all other proper demands on the income of its endowment.” It advised as to administrative and research activities and other matters as to which there is no present issue. It also advised that the proposed removal was justified if the conditions stated in the opinion were met. It concluded with the observation that “there is persuasive evidence that the move will promote the purposes of the Arboretum.”
The Corporation acted in the light also of a memorandum from President Conant of October 15, 1952, in which he argued at length in favor of the removal of the main part of the library and herbarium to Cambridge. He gave various reasons in support of the position “that the work of the Arnold Arboretum may be carried on more effectively” if the move were made. He pointed out also that the removal would “assist all those concerned with a knowledge of botany.” Stress was laid on the aid to teaching the knowledge of trees in the university which would result from the presence of the library and herbarium in Cambridge. He characterized the Arnold Professor as a “part of the University.” This memorandum reflected his final decision as to the removal.
At a meeting of the Corporation on January 5,1953, there was read a letter from Mr. Grenville Clark, one of the rela-tors, and a former member of the Corporation, who had [141]*141resigned in November, 1950, with enclosed memoranda prepared by Professor Lawrence, the head of the Hunt Botanical Library in Pittsburgh and director of the Bailey Hor-torium, a botanical institution operated by Cornell University, and by Professor Slate, a professor at Cornell. The Corporation thereupon decided that, “at least as a matter of record,” certain other outside scientists should be consulted. On January 17, 1953, a committee of President Conant and Messrs. Marbury and Kane conferred in New York with Mr. J. George Harrar, Director of Agriculture for the Rockefeller Foundation in Mexico, Professor Paul B. Sears, Professor of Conservation in charge of the Agricultural Conservation Department of Yale University, and Dr. David B. Keck, Head Curator of the New York Botanical Gardens. Each was consulted individually. President Conant showed them the resolution of the Board of Overseers of January 12, 1953, and read them the provisions of the 1872 Indenture. The three persons consulted replied affirmatively to the inquiry whether the move would be “the best way of carrying out the terms of the trust.” Each agreed that the work of the Arnold Professor would be assisted by the move and that the Arnold Professor and his staff could work efficiently, partly in Cambridge and partly in Jamaica Plain. ‘ ‘Dr. Keck, at least, was asked whether, in his opinion . . . the move would be desirable from the standpoint of botany at Harvard University.” He replied that in his opinion it would. Asked as to the effect on the Arboretum, he pointed out “what he considered to be the disadvantages of the move from the Arboretum’s standpoint.”
The master noted that the basis for choosing the consultants or who chose them does not appear and that the qualifications of Messrs. Harrar and Sears are not shown and expressed the view that “their titles as of the time of consultation give no basis for placing confidence in their judgment on the matters presented to them for opinion.”
There is no suggestion in the findings that President Conant’s opinion that the move would permit the work of the Arboretum to be carried on more effectively did not re-[142]*142fleet his best judgment on adequate evidence or that it was untenable for one giving due regard to the nature of that work as required under the Indenture. We put aside for the moment the issue of the possible effect on prestige and reputation. Certain of the findings suggest that the reference to outside experts was perfunctory. We think it was adequate for its purpose. The aim of the members of the Corporation was, it appears, to let the record show that, accepting their premises, there was professional support outside the university for the decision. Contrary to the master’s comment, we think that there is implicit in the titles of the consultants a suggestion of a background of experience and professional standing that would give a degree of substance to their opinion.
We do not overlook the master’s findings that the decision to move was made because of a belief that it would “promote the science of botany as a whole at Harvard (rather than the interests of particular botanical institutions).” We do not construe this as a finding that the Corporation disregarded the carrying out of the express purposes of the 1872 Indenture. It is coupled with the finding that the Corporation believed the removal to be consistent with the Corporation’s obligations with respect to the Arboretum assets. It does not negative the declared views of the President and the Corporation that the move to benefit botany as a whole at Harvard would be “in the . . . best interests of the Arboretum and . . . promote the purposes of its endowment.” The finding that the Corporation accepted the view of the Coordinating Committee that the Arboretum should be regarded as an instrument in the development of botany as a whole must be read with other findings that, in our view, show that the Corporation did not undertake to use the Arboretum as such an instrument except after finding, on an appropriate showing, that the course to be followed would advance the particular purposes of the Arnold trust. To the extent, if any, that the master’s report may be thought to suggest otherwise we draw different conclusions from the specific findings.
[143]*143Implicit in the master’s findings is the conclusion that if the Corporation had accepted “the best interests of the Arboretum” as an important criterion, its members, acting with due care and in good faith, must have decided against the move. A decline in the reputation, prestige, and standing of the Arnold Arboretum as a separate institution was, we think, reasonably foreseeable. But the purpose of the 1872 Indenture was not the maintenance of the prestige, reputation, and standing of the institution or department that might evolve over the years in connection with the use of the trust funds by the Corporation to build the Arboretum. Nor were these intangible attributes solely the fruits of the trust fund. They resulted in part from the association of the Arboretum in the group of related Harvard institutions and departments, the interplay between these departments, and the management of the Arboretum by the managers of the university. Whether the Corporation could rightly risk impairment of the prestige of the Arboretum regarded as a separate institution depended upon whether the steps taken, in reasonable likelihood, would impede or promote the stated purposes of the public trust, the funds of which had been used in the creation of that prestige.
There was ground for concluding that the net result would be to promote those purposes. The Arboretum would continue as a part of a group of botanical science departments that was expected to attain outstanding preeminence. The outcome that the master has found was foreseeable: the creation of “a world famous scientific station” with “one of the greatest libraries and herbaria in the world.” The members of the Corporation could reasonably conclude that in the long run the accomplishment of all the specific scientific and teaching purposes of the Indenture of 1872 would be aided by the move and that outstanding scientists, scholars and students would be at least as much attracted to association with the Arboretum as before, and, in reasonable likelihood, more so, and that their work on the whole would benefit.
[144]*144Therefore, so far as transferring the prestige from the Arboretum to the university was a use of an asset of the Arnold trust fund, that transfer was, prospectively, a use of the asset for the accomplishment of specific public charitable purposes of the Indenture that established that fund and not a breach of trust. The prestige was not, in our view, a capital asset, which, once accrued, could not be expended.
To act in “the best interests of the Arboretum” means, in our view, to serve advantageously the stated purposes of the trust and not necessarily to maintain the separate reputation of the Arboretum. “ [T]he trustee of a charitable trust owes duties but . . . not ... to any person or persons in particular, although they are enforceable at the suit of a public officer for the benefit of the community.” Scott, Trusts (2d ed.) § 348, p. 2552. See also § 379, p. 2735.
The prospective adverse effect of the move on the reputation, standing, and prestige of the Arboretum was, of course, highly important apart from its legal aspect. Such an institution, although a subdivision of university activity, develops a separate personality and generates the loyalty and support of teachers, staff, alumni, donors, and friends. These, we think, are the considerations that the members of the Corporation had in mind in concluding, as the master found they did, that moral issues were involved that could not be settled by a legal adjudication. These considerations — the effect of the move on the loyalty and interest of many persons close to the university and devoted to it and the Arboretum, as well as a due regard for their views — although properly of most serious concern to the Corporation, cannot affect our rulings. It is appropriate for us say, however, that the report, as we view it, shows that the members of the Corporation did not overlook them, but found them overbalanced by the other factors necessarily weighed by them. The report does not show or suggest that the Corporation was acting to increase the prestige of Harvard University as an end in itself.
The findings of the effects of the move do not show that inadequate consideration was given to probable results or [145]*145that had judgment was exercised. There is an implication that the “marked disadvantage” in carrying on taxonomic research in Cambridge more than offsets the advantages therefrom. But the master was unable to find either improvement or decline in the continuing work of the Arboretum and it is of course too soon to judge the long run effects. Nothing in the report shows that those effects will not be of net benefit in the accomplishment of the specific trust purposes of the 1872 Indenture.
What we have said disposes of the contention that the move itself, so far as carried out as voted, was a breach of trust.11 We disagree with the view of our dissenting colleagues that it is implicit in the Indenture that the place of such implied related activities as the library and herba-rium, if established, be the place specified for the growing of the trees, shrubs and plants. The dominant consideration is that those things and only those things be done that will, in the good judgment of the Corporation, promote the express purposes of the Indenture. There is no implication that, to promote those purposes, the library and herbarium could not be maintained at Cambridge. This is tested, we suggest, by considering whether, if these facilities had been originally established and always heretofore maintained in Cambridge, it could now be contended that there had been a breach of trust.12 In certain aspects, however, the implementation of the resolution of January 19,1953, does not, or may not, conform to its terms.
The master’s report states “the evidence does not warrant a conclusion that either the library or the herbarium at Jamaica Plain is reasonably adequate for horticultural or other work.” The resolution calls for the retention at Jamaica Plain of “such books and specimens as may be required to provide there a working library and herba-[146]*146rium.’’ The implication from the master’s observation and from the finding that the working library and herba-rium were gathered by selecting duplicates of items taken to Cambridge may be that the intention of the Corporation’s vote has not been met.
The resolution required that the books and specimens to be housed at Cambridge be appropriately identified. We hold that this includes identification of the books on the card catalogue and of the specimens on a catalogue, if any, or on some other form of general listing, if feasible. Also we think that appropriate identification calls for a sign or legend of substantial size on the outside of, or in the foyer or a general room of, the Harvard University Herbarium stating in some form of words that the books and specimens include those of the Arnold Arboretum.
The interlocutory decrees are affirmed.
The rescript shall provide that the county court retain jurisdiction of the cause and that the defendant shall file with the clerk within six months of rescript (a) a report to it by the Arnold Professor or other appropriate person that in the Corporation’s judgment shows either that an adequate working library and herbarium exist at Jamaica Plain or recommends the steps to cause them to exist; (b) a report of its proposals or action to amplify the catalogue and general listing references; and (c) a report of its proposal or action in respect of a general designation on or within the Harvard University Herbarium.
A final decree affirming the validity of the Corporation’s votes and acts as modified by the foregoing changes shall enter when it shall appear to the single justice that such changes, adequate to conform to this opinion, have been made or are assured.
So ordered.
