Dowling, J.:
The defendant has been convicted of the crime of manslaughter in. the second degree, under the provisions of. section 193, subdivision 3, of the Penal Code (now section 1052, subdivision 3, of the Penal Law). This section defines homicide as manslaughter in the second degree when committed without a design to effect death “by any act, procurement or culpable negligence of any person, which, according to the provisions of this article, does not constitute the crime of murder-in the first or second degree, nor -manslaughter in the .first degree.”
The defendant was a licensed blaster and had been' engaged in blasting for a period of about two months on the premises at the corner of Freeman street and Southern boulevard in the city of New York, when, on September 11, 1909, he set off a blast the results- of which Were so extensive that rocks were scattered over the territory to the west of the plot on which he • was working, three persons were struck thereby, and a boy' who was standing on the stairway of the elevated station from 125 to 110 feet distant, was struck by a piece of the rock projected'therefrom, with such violence that his skull was crushed in and part of his brains scattered on the stairs. The unusual violence of this explosion is not denied and the only explanation sought to be made by the. defendant is that the • [111] rock on which he was working had theretofore been soft rock and his operations had been conducted without accident of any kind; but that without his knowledge the character of the ground in which this particular blast was operated was a deposit of hard rock, as the result of which, though using the same amount of powder as he had theretofore employed, it produced results far more violent than the prior ones. Defendant claimed that he had used about two and one-half pounds of powder as a charge in each drill hole, while the testimony of the expert witnesses called by the prosecution agreed that the amount used in the holes in question must have been from ten to eleven pounds, and that the reasonable and adequate amount of powder to place therein would have been five pounds. Accepting the testimony of the prosecution, as the jury did, that the defendant, conducting his blasting operations in rock on a'Saturday afternoon, within the limits of a city, with persons within the zone of his operations liable to suffer damage or death by reason of any carelessness or unskillfulness on his part, had placed in these drill holes double the amount of powder which careful use would require, as the. result of which he had caused the death of a human being, the jury could not have reached any other conclusion save that he had been guilty of such culpable negligence as brought him within the provisions of the statute. The severity of the results produced is in itself the best evidence of the excessive force negligently applied, and we do not deem it necessary to do more than discuss the exceptions assigned as a ground for reversal. The defendant’s admission that the results produced by this blast were so severe because he was working in hard rock instead of soft, is an admission that too much powder was used for the kind of rock which hé was then blasting; and his failure to so conduct his operations as to make the force applied proportionate to the nature of his work, when negligence in that respect would place in jeopardy the lives of others, is in itself gross carelessness and involves the doing of an act dangerous in itself without taking proper precautions to prevent danger arising therefrom; and when the death of a person results therefrom^ even though there be no malice or evil design, the act is zat least manslaughter. (Whart. Hom. [3d ed.] 680.)
[112] It is sought to secure reversal of this judgment upon the ground that it was error to permit the propounding of hypothetical questions to two expert witnesses called by the prosecution. Their qualifications as experts having been established they were asked to answer the following question varying slightly in its form as put to each witness: “Assume * * * that a hole is twelve-feet deep, two and a half inches in diameter at the bottom, three and a half inches in diameter at the top, and contains from the bottom up 36 to 38 inches of powder, four feet of tamping above that, and above that eight inches of powder, and over that three to four feet of tamping, what in your opinion would you say would- be the approximate amount of powder in that hole ? ” Objection is made to this question on the ground, among others, that it involves an opinion based-on the personal observation of the witness as well as the hypothetical conditions; but the qtiestion is not open to that objection. It is true that the court suggested an addition in these words: “What in your opinion, assuming these facts, to be true and coupled with the result of your own observation after. experience in blasting, Would be the. approximate amount of powder ? ” But when objection was made to this addition to the question by defendant’s counsel the court expressly said that he did not put it as a question, but as a suggestion, and as a matter of fact the question in that form • was not put - or answered; and what the witness replied to was the original question quoted. This was a case peculiarly for expert testimony and one in which the knowledge of a layman would have been entirely inadequate to enable him to form an opinion as to the amount in weight of explosives in a hole, part of which was filled with tamping. Apart from the question of' whether or not the defendant had properly protected his work, in order to prevent rocks flying therefrom when the blasts were fired, the other important question was whether he had used. an excessive and unsafe amount of powder for the work which was then being done and an amount disproportionate to the size of the hole which had been drilled therefor.

This was a case peculiarly for expert testimony and one in which the knowledge of a layman would have been entirely inadequate to enable him to form an opinion as to the amount in weight of explosives in a hole, part of which was filled with tamping. Apart from the question of' whether or not the defendant had properly protected his work, in order to prevent rocks flying therefrom when the blasts were fired, the other important question was whether he had used. an excessive and unsafe amount of powder for the work which was then being done and an amount disproportionate to the size of the hole which had been drilled therefor.
, We are of opinion that the questions referred to offered proper subjects for expert opinion and were correct both in substance'- and form. -The facts upon which. the opinion evidence [113] wan founded were all assumed in the hypothetical question, which answers the requirements of the rale laid down in Dougherty v. Milliken (163 N. Y. 527). (See, also, Weibert v. Hanan, 202 N. Y. 328.) If on cross-examination it developed that the witness had relied in any way in arriving at a conclusion on personal observations not already testified to, it would of course have been competent then for the defendant to have moved to strike out his response to the hypothetical question, which in itself, however, conveyed no suggestion of any element t*o be considered in" reaching a conclusion save those expressly included therein. Nor was the other question propounded to the expert witnesses, “Will you state from your .knowledge and' experience as a blaster what would be a reasonable and adequate amount of powder to place in those drill holes,” for the diameter and depth of the holes had already been stated to thém in the prior hypothetical question, to which this was immediately related. Nor were the jury superseded in their right of determining the question of whether or not the operations conducted by the defendant were safely conducted by him, for what the witnesses were called upon to give expert opinion concerning was (1) the amount of powder in the holes in question; (2) the reasonable and adequate amount thereof to place in these holes. If the jury credited their testimony as against that of the defendant it was still for them to determine whether, conceding the testimony of the witnesses for the prosecution to be true, the disproportion between the amount of powder used and the amount adequate for the work to be done was so great as to constitute culpable negligence upon the part of the defendant. Nor was error committed in the admission of sections 61 and 62 of the rules of the municipal explosives commission. These sections had to do with the amount of explosives to be used and the precautions required to be taken to guard the surface affected. They had been in effect since May 19, 1902, and the defendant, as an experienced licensed blaster, should have known of them and been aware of the regulations they established for safe blasting.
The admissibility of section 62 as some evidence of negligence and as suggesting what proper blasting should be was sustained [114] in Burke v. City & County Contract Co. (133 App. Div. 113), and section 61 is admissible upon the same reasoning.
There is no other error assigned which, in our opinion, requires discussion; nor do we find any error.sufficiently prejudicial to warrant a reversal of this conviction.
• The judgment appealed from must, therefore, be affirmed.
