WOODSON, J.
This is • an appeal from the judgment of the circuit court of the city of St. Louis, in favor of the respondent, for the sum of $10,540.78, growing out of certain transactions on the floor of the Merchants ’ Exchange of the city of St. Louis.
In order to fully understand the questions involved in the case it is necessary to set out the pleadings.
The petition is as follows:
[642]*642“Plaintiff states that defendant, the Thyson Commission Company, is a general business corporation, organized under the laws of Missouri, and at the times of the transactions hereinafter stated was engaged through its representative, one John Thyson, in the business of selling grain on the floor of the Merchants’ Exchange in the city of St. Louis.
“Plaintiff for his action states that heretofore, to-wit, on July 14, 1903, plaintiff’ employed defendant through its said representative to buy for plaintiff as his agent one hundred and fifty thousand bushels of number 2 red winter wheat to be delivered in the month of December, 1903, under the rules of said Merchants’ Exchange in the city of St. Louis. Defendant accepted said commission and executed the same by buying for plaintiff’s account said 150,000 bushels of wheat on the floor of the Merchants’ Exchange in St. Louis, and reported the said purchases to plaintiff. Thereafter, on November 20, 1903, plaintiff ordered defendant to sell the said wheat so purchased for his account, and defendant executed said order of sale and sold said wheat for defendant, realizing therefrom a net profit over and above said purchase price of $10,381.25, which said profit defendant realized as plaintiff’s agent and for plaintiff’s account as will appear from the statement of said account herewith filed and made a part hereof as ‘Exhibit A.’
“Plaintiff states that although demand has been made upon defendant for said amount, defendant refuses to pay same, or any part thereof.
“Plaintiff says that the said transaction was fiduciary, in that the defendant acted as plaintiff’s agent, made the said purchase and sale for plaintiff’s account as such agent, and has appropriated and unlawfully converted the said sum thus belonging to plaintiff to its own use.
“Wherefore plaintiff asks judgment against de[643]*643fendant for said sum of $10,381.25, with interest from November 20th, 1903.”

To the petition the appellant filed the following answer:
“By way of amended answer to the petition of plaintiff, the defendant denies, that on July 14, 1908, or at any time, plaintiff employed defendant, through its alleged representative or otherwise, to buy for plaintiff one hundred and fifty thousand bushels of number two red winter wheat to be delivered in the month of December, 1903, under the rules of the Merchants ’ Exchange of St. Louis, or that the defendant accepted such commission or bought said one hundred and fifty thousand bushels of wheat. The defendant denies, that in the month of November, 1903, [644]*644or at any time, at plaintiff’s instance, the defendant sold for plaintiff one hundred and fifty thousand hushels of wheat theretofore purchased for plaintiff, .or any quantity of wheat theretofore purchased hy defendant for plaintiff, or that from such sale a net profit was realized of $10,381.25', or any other sum. The defendant denies that it has converted to its own use any sum of money or proceeds of sale, which belonged to plaintiff, or that it is indebted in any manner to the plaintiff.
“Farther answering, the defendant states, that beginning with July 14, 1903, and ending August 12, 1903, at the instance and by the direction of the plaintiff, the defendant bought wheat for delivery in the month of December, 1903, in St. Louis, under the rules of the St. Louis Merchants’ Exchange, from the persons, in the quantities and for the following prices per bushel, to-wit:

‘ ‘ That at the times of the said respective purchases the defendant by direction of the plaintiff sold for [645]*645delivery in the month of May, 1904, in the city of Chicago, Illinois, under the rules of .the Chicago Board of Trade, an equal quantity of the same grade of .wheat, thereby effecting what are known to dealers in futures as spreads between St. Louis and Chicago; that the Chicago transactions were subsequently closed out by direction of the plaintiff, leaving the St. Louis trade still open; that at various times, between July 29 and September 1, 1903, the said trades, hereinbefore specified, were rung out, or closed under the rules of the St. Louis Merchants’ Exchange, in some instances with a loss, and in other instances with a profit, the net result being a profit of $1,350 which the defendant has always been ready and willing to pay to the plaintiff.
“Farther answering, the defendant states that on November 20, 1903, it sold for the plaintiff one hundred and fifty thousand bushels of wheat for delivery under the rules of the St. Louis Merchants’ Exchange in the month of December, 1903; that theretofore defendant had bought at various times between July 14 and August 15th of said year for plaintiff’s account and at his instance and request one hundred and fifty thousand bushels of wheat for the same month’s delivery; that the wheat sold on account of plaintiff was not wheat belonging to plaintiff, but which was covered by contracts with others for delivery in said month of December; that in the month of December defendant delivered one hundred and fifty thousand bushels of wheat for the account of plaintiff, at the price made in November, and received the proceeds of sale therefor; that persons from whom wheat had been bought as aforesaid on account of plaintiff made default on their contracts in the said month of December and are still in such default and owe to defendant the amount due under their contracts at the prices thereunder made; that the matters thus standing between plaintiff and defendant are still open and unadjusted, [646]*646although, defendant believes and states the fact to be, that upon the performance of their contracts by said sellers, there will be a net result or profit to plaintiff of some thirteen hundred and fifty dollars.”
The respondent thereupon filed the following reply:
“Comes now plaintiff and for reply to the amended answer of defendant herein, admits that beginning with July 14, 1903, and ending August 12, 1903, at the instance and by the direction of plaintiff, defendant bought a total of 150',0001 bushels of wheat for delivery in the month of December, 1908, in St. Louis, Missouri, under the rules of the St. Louis Merchants ’ Exchange, from the persons, in the quantities and for the prices per bushel set out on page 2 of said amended answer; but plaintiff says that he has no knowledge or information as to whether the said trades specified were at various times between July 29th and September 1,1903, ‘rung out’ or closed under the rules of the St. Louis Merchants’ Exchange, and plaintiff further says that if the said trades hereinbefore specified were so ‘rung out’ or closed by defendant under the rules of the Merchants’ Exchange, it was done by defendant without the knowledge or consent of plaintiff, and plaintiff does not know and has no information as to whether these trades were so closed out at a profit or otherwise, and is in no way concerned or affected thereby, for' the reasons hereinafter set forth.
“Further replying to said amended answer plaintiff admits that on November 10, 1903, defendant sold for plaintiff one hundred and fifty thousand bushels of wheat for delivery in the month of December, 1908, and that theretofore defendant had bought at various times between July 14, 1903, and August 15, 1903, for plaintiff’s account, and at his instance and request, 150,000 bushels of wheat for the same month’s delivery, and plaintiff admits that in the month of December defendant delivered 150,000 bushels of wheat for the account [647]*647of plaintiff at the prices made in November, and received the proceeds of sale therefor. Plaintiff further says that he has no knowledge or information as to whether the 150,000 bushels of wheat so sold on account of plaintiff was or was not the 150,000 bushels -of wheat bought for plaintiff, or as to whether it was wheat which was covered by contracts with others for delivery in said month, and he has no knowledge or information as to whether or not the persons from whom defendant alleges it bought wheat on account of plaintiff made default on their contracts and are still in default, and plaintiff says that he is not in any way concerned or affected by said alleged facts, for the reasons hereinafter set forth.
“Further replying, plaintiff denies that the account between plaintiff and defendant is still open and unadjusted as alleged in said amended answer; but on the contrary plaintiff alleges that all the aforesaid transactions between plaintiff and defendant occurred on the Merchants’ Exchange of the city of St. Louis and were and are subject to the rules and regulations of said Merchants’ Exchange, that in and by section 13 of Eule YIII of said Merchants ’ Exchange it is provided as follows:
‘ ‘ ‘ Sec. 13. In case any member of the Exchange, acting as commission merchant, shall have made purchase or sales, by order, and for account of another, whether the party for whom any such purchase- or sale was made shall be a member of the Exchange or otherwise, and it shall subsequently appear that such trades may be offset and settled by other trades made by said commission merchant, he shall be deemed authorized to make such offset and settlement, and to substitute some other person or persons for the one from or to whom he may have purchased or sold the property originally; provided, that in case of such substitution the member or firm making the same shall be held to guarantee to his or their principal the ultimate fulfillment of all con[648]*648tracts made for account of such principal which have been so transferred, and shall be held liable to1 such principal for all damages or loss resulting from such substitution, subject, however, in' all respects to the rules of the Merchants ’ Exchange. ’
“Plaintiff therefore says that by ringing out or closing without plaintiff’s- knowledge' or consent the trades theretofore made at the instance and request of plaintiff between July 14th and August 12, 1903, by which defendant purchased a total of 150,000 bushels of wheat for account of plaintiff for December delivery, as alleged in the answer herein, and by failing to keep the identical wheat purchased for plaintiff until plaintiff directed it sold, defendant thereby guaranteed and became itself liable to plaintiff for the fulfillment of all these transferred or substituted contracts for December delivery, and is liable to plaintiff for the amount claimed in his petition, whether the persons from whom defendant purchased wheat in these transferred or substituted contracts have made default or not.
“Wherefore plaintiff again prays judgment in accordance with the prayer of the petition herein. ’ ’
At the trial, which was before a jury, the respondent offered to read in evidence the following part of the amended answer of the appellant, to-wit:
“Further answering the defendant states, that beginning with July 14,1903, and ending August 12, 1903, at the instance and by the direction of the plaintiff, the defendant bought wheat for delivery in the month of December, 1903, in St. Louis, under the rules of the St. Louis Merchants’ Exchange, from the persons, in the quantities and for the following prices per bushel, to — wit ¡

“Further answering, the defendant states that on November 20,1903, it sold for the plaintiff 150’,000 bushels of wheat for delivery under the rules of the St. Louis Merchants’ Exchange in the month of December; that theretofore defendant had bought at various times between July 14th and August 15th of said year for plaintiff’s account and at his instance and request for the same month’s delivery; that in the month of December defendant delivered 150',000' bushels of wheat for the account of plaintiff and received the proceeds of sale therefor.”
To the introductiqn qf this evidence the appellant objected on the ground that it was not competent evidence under the petition, and that it was a variance from the petition, which objection the court'overruled, and the appellant duly excepted. The respondent then read in evidence the part of the answer indicated.
Whereupon, the appellant read the remainder of the amended answer.
John T. Milliken, respondent, testified that July 14, 1903, he gave to the appellant, through its representative, on the floor of the St. Louis Merchants’ Exchange, an open order for the purchase of 150,000' bushels of wheat for December delivery. He received from the appellant memoranda of purchase July 14th, August [650]*6505th, August 3rd and August 12, 1903. The respondent offered these in evidence. They were objected to as incompetent, the objection was overruled, and appellant duly, excepted.
The first of these memoranda is of July 14, 1903, showing a purchase of 25,000 bushels of wheat, December delivery, at 77 1-2 cents per bushel; the purchase being made on St. Louis Merchants’ Exchange.
The second is of August 3, 1903, showing a spread between St. Louis and Chicago, as follows:
St. Louis — Bought:
25.000 December..................82-$c
10.000 December..................82

The fourth is August 12,1903, showing as follows: St. Louis, — Bought:

10.000 May......................82f
5.000 May.....................82$
15.000 May......................82$
10.000 May......................82$
The witness stated that he told the representative of the appellant, “whenever he could buy 150,000' bush[651]*651els of December wheat in St. Lonis at one-half cent under the price of May wheat in Chicago, that he could buy the wheat at St. Louis and sell it in Chicago as a hedge, but I had the privilege to discontinue at any time I wanted to.” He was asked, “What became of the sales made for your account by him in Chicago?” This was objected to as incompetent. The objection was overruled and appellant excepted. The witness states that “they were brought in and showed a profit of several thousand dollars, which was paid to me.”
November 20, 1903, respondent received from appellant the following memorandum:
“We have the pleasure of confirming the following transactions made for your account and risk to day:
“Sold 150 December wheat, St. Louis. .884-.”
After receiving this statement, witness demanded' settlement, but none was made. No payment on account of it was ever made.
The respondent offered in evidence section 13, Rule 8, Merchants’ Exchange, St. Louis, which is copied in the reply.
The appellant objected to the testimony as not competent, for the reason that the respondent undertook by a reply, which was a departure from the petition, to tender a totally different issue from that tendered by the petition.
Upon the objection being overruled, appellant excepted, and upon the reading of the section moved that it be stricken out on the following.grounds:
That in addition to being incompetent, it showed' on its face that the only condition it could create was one of liability in damages for the failure of persons who were substituted for the original contractors to carry out the contracts made by those original parties. It created no independent liability on the part of the commission merchant who made the trades in the first instance, but simply undertook to hold him responsible for the performance of the contracts by those with [652]*652whom they were made, in case of substitution of other persons under the contracts. That is all it undertook to do. The rules had not been pleaded by either party tó the suit.
This motion having been denied, appellant excepted.
Daniel L. Moffit, over the objection of the appellant, exception being saved to the admission of the evidence, testified that he bought 150,000 bushels of wheat from the appellant in November, 1903, at 88-J, for December delivery. On December 1st it was delivered, witness paying the cash. The delivery was not of any specific wheat, but merely warehouse receipts calling for 150,000 bushels.
Corwin H. Spencer testified that the words “ringing out” mean off-setting sales by purchases by the commission men as between themselves, as the contracts of purchase and sale made by them on the floor of the Exchange were made in their own names. But that this offsetting was a mere matter of convenience for the expeditious dispatch of business, and in no wise affected the relations of the commission men to their customers, who were bound to settle with their customers according to their respective contracts made in their behalf.
This was all the evidence in the case, and appellant demurred thereto, which was overruled, and appellant duly excepted.
The court then, over the objection of the appellant, instructed the jury as follows:
‘ ‘ The court instructs the jury that under the pleadings and evidence herein their verdict should be for plaintiff for the total sum of $10,540.78, being the amount sued for in the petition, with interest thereon at 6 per cent per annum from November 20, 1903, the date plaintiff demanded payment from defendant. ’ ’
To the giving of which instruction appellant duly [653]*653excepted, and within four days filed his motion for a new trial, which was overruled, and it duly excepted.
I. The first ground relied upon by appellant for a reversal of the judgment is, the court erred in admitting in evidence that portion of the answer 'offered by respondent.
The petition alleges that on “July 14, 1903, plaintiff employed defendant through its said representative to buy for plaintiff as his agent one hundred and fifty thousand bushels of number 2 red winter wheat, to be delivered in the month of December, 1903, under the rules of said Merchants’ Exchange of the city of St. Louis. Defendant accepted said commission and executed the same by buying for plaintiff’s account said one hundred and fifty thousand bushels of wheat on the floor of the Merchants’ Exchange in St. Louis, and reported the said purchase to plaintiff. Thereafter, on November 20, 1903, plaintiff ordered defendant to sell the said wheat so purchased for his account, and defendant executed said order of sale and sold said wheat for defendant, realizing therefrom a net profit over and above said purchase price of $10,540.25, which said profit defendant realized as plaintiff’s-agent and for plaintiff’s account, as will appear from the statement of said account herewith filed and made a part hereof as 'Exhibit A.’ ”
It will be seen from reading the allegations of the petition, in connection with the account filed therein, that the respondent charges appellant with having purchased for him 150',000 bushels of wheat in nine separate lots, each varying in price, which is stated,' aggregating the sum of $122,275.00'. The petition does not state the dates of the several purchases nor the names of the persons from whom the purchases were made.
In order to prove these allegations of the petition, the respondent introduced in evidence that portion of [654]*654the answer relating to the purchase and sale of the wheat in the city of St. Louis, which stated, in substance, that appellant had purchased for respondent, at various times, between July 14th and August 12, 1903, giving the dates, seventeen different lots of wheat from different parties, naming them, aggregating 150,000 bushels, at various prices,- stating them. But respondent did not offer that part of the answer relating to the purchase and sale of the Chicago wheat.
To the introduction of that evidence appellant objected; first, because it was not competent under the petition, and did not tend to prove any of the allegations thereof, but was a variance therefrom; and, second, because appellant. set up the various purchases, not for the purpose of admitting that they constituted the transactions between them, hut for the purpose of showing what were the.real transactions between the parties, upon the theory that perhaps under a general denial the appellant might not be at liberty to go into them.
The transactions stated in the petition are totally different from those stated in the answer and introduced in evidence by the respondent.
It is a well-established rule of pleading that a party cannot state one cause of action and recover on a different one. [Weil v. Posten, 77 Mo. 287; Reed v. Bott, 100 Mo. 66; Leslie v. Railroad, 88 Mo. l. c. 54.]
It was also error for the court to permit respondent to select isolated portions of the answer and read them to the jury, when the whole answer taken together shows, as this one does, that the very object and purpose of it was to deny, not to admit, the allegations of the petition.
An answer or other pleading in a cause, when offered in evidence, should be construed by the court just as deeds or other written instruments are construed. The object to be attained in the construction of a [655]*655written instrument is to get at the real intention of the parties. [Burress v. Blair, 61 Mo. 133; Koehring v. Muemminghoff, 61 Mo. 403.] Effect should he given to the whole and every part of a written instrument. [Calloway v. Henderson, 130 Mo. l. c. 86.]
The construction placed upon the answer, instead of giving force and effect to all of its provisions, had the effect of striking out the real transaction between the parties, as stated in the answer.
II. Respondent introduced no evidence tending to prove the purchases and sale's of wheat for him by appellant, as alleged in the petition, and for that reason the court should have given appellant’s demurrer to the evidence.
Where the evidence furnishes no substantial support of the allegations of the petition, then it is the duty of the court to instruct the jury to find for the defendant. [Hyde v. Railroad, 110 Mo. 272.]
III. The trial'court erred in giving the peremptory instruction to the jury, telling it to find for the respondent. This would have been true, even though he had introduced evidence tending to support his cause of action.
The rule is, that when the allegations of the petition are denied, and evidence is submitted to sustain the issues joined, the defendant is entitled to have the jury pass upon the evidence, though the defendant offers no evidence on his own part. [Wolff v. Campbell, 110 Mo. 114; Gregory v. Chambers, 78 Mo. l. c. 298.]
For the reasons above stated the judgment is reversed and remanded for retrial.
All concur.
