While Harold Eves was endeavoring to remove the explosive substance from a dynamite cap for the purpose of making a whistle, the cap exploded, and blew the thumb and forefinger off his right band. This action, prosecuted in the name of his father, as guardian, is to recover damages from the Littig Construction Company, which is charged with having carelessly and negligently left a box containing three dynamite caps on the bank of a deep cut made by the construction company in a public highway, where it was found and the caps removed by Harold on the morning of August 5, 1923. The box containing the caps was lying in a depression on the surface of the ground, in plain view of a person walking on the bank of the cut near the fence line. Immediately before discovering the box, Harold was accompanied by two companions, but they had climbed down the embankment, and did not see him pick it up. He showed the box and caps to them, but they did not know ivhat they were, but supposed they were 22-rifle cartridges. *1340Harold threw the box in a near-by culvert, put the caps in his pocket, and took them home with him, a distance of about % of a mile. In the afternoon, he attempted to remove the contents of the caps; and, while he was in the act of scratching one of them upon a piece of cement, the explosion occurred, with the results stated.
There are two culverts in the highway near the place where the box was found, the nearest about 20 rods distant. In April of the same year, a bridge construction gang used dynamite for blasting trees and stumps in the highway near the culverts. The bridge company completed its work in April or May, and went away. The appellant came later, and used dynamite for blasting trees and stumps in the highway at and near the point where the box was found. After the trees and stumps had been blasted, the elevation was cut down, and the dirt removed therefrom used in making a fill or embankment in the highway. Appellant completed its work the latter part of July. No other construction company or person in the community is known to have possessed explosives of the character in. question. The box in which the caps were found was about two inches square, the exterior bright, without paint or lettering of any kind thereon. The identification of the box is one of the close questions of fact in the case.
A motion was made by appellant for a directed verdict, at the close of plaintiff’s case, and renewed after both parties had rested.
A lax-ge number of the propositions relied upon for reversal are predicated upon the grounds stated in the motion for a directed verdict. The substance of these grounds was that the' box containing the caps was not identified as the property of appellant, and that possession thereof was not traced to its foreman or other servants; that the evidence was insufficient to prove that the box was left or placed in the depression where it was found, by appellant, its servants, or employees; that Harold Eves was a trespasser at the time he discovered and picked up the box; that he was guilty of contributory negligence and of wrongfully and unlawfully intermeddling with property that did not belong to him; that no negligence on the part of appellant was shown which was the proximate cause of the accident; and that the result was not one that appellant in the lawful use *1341of explosives was bound to anticipate as reasonably likely to occur. Tbe .elevation of tbe bank at. the point where the box was found was approximately twelve feet above the surface of the finished highway. The sides or slopes of the bank were steep, and the boys reached the top by walking close to the fence line on the natural surface of- the ground. The incline was gradual,’ and apparently not difficult of ascent. The foreman of the appellant construction company denied emphatically that he ever saw the tin box containing the caps until it was presented as an exhibit upon the trial. One witness said that he saw the box on the top of the bank near where it was found, while, they, were working in the highway about ten days prior to August 5th. Other witnesses , testified that they saw the foreman .have a tin box similar in size and appearance, which he kept part of the time in a tree, and part of the time by a fence inside an inclosure near .the highway. The box offered in evidence was found by Harold’s father, who was accompanied and directed in his search therefor by one of the small boys who were with Harold on Sunday, in the culvert where it was thrown. He took -the box home, and retained it until the time of the trial. In the meantime, it had become rusty, which gave it a somewhat different appearance from what it had when found. An effort is made by appellant to cast doubt upon the identification- of the box by showing that the foreman of the bridge company had a small, similar box in which he also kept dynamite caps. The box, however, as stated,-was not found near the culvert, but in the immediate vicinity of the place where appellant had, not more than ten days prior, been working. The identification is, of course, not conclusive, but was sufficient to require the submission of the question to the jury. No direct testimony was offered to prove when the box was left upon- the bank, or .how it came to be abandoned by appellant, if it was left there by its foreman. This was not essential, to make out a case for the jury.
I. The law is well settled and universal that one dealing in, using, or handling explosives must exercise .the highest degree of care to prevent injury to property or per- . * ^ sons:.-that -is, such care as is commensurate -^ith 0£ substance and the dangers incident to the handling or use thereof. Lanza v. Le Grand Quarry Co., 124 Iowa 659.
*1342The tendency of small boys to possess themselves of boxes and other objects of attractive appearance found upon the streets or highways is proverbial, and it was the duty of appellant, in the use and handling of a- deadly explosive, to guard them against such perils as might reasonably be foreseen to occur. Whatever might happen that was within the range of prudent human foresight, it was in duty bound to guard against. Its liability, if any, must rest upon some violation of this duty which was the proximate cause of the injury. The duty of one employing explosives'to exercise the highest degree of care for the safety of others is everywhere recognized and sustained by authority. The following cases will serve to illustrate both the rule and its application to a great variety of circumstances in which recovery was permitted. Nelson v. McLellan, 31 Wash. 208 (71 Pac. 747); Clark v. Du Pont De Nemours Powder Co., 94 Kan. 268 (146 Pac. 320); Cahill v. Stone & Co., 153 Cal. 571 (96 Pac. 84) ; Erickson v.

The whole subject is fully discussed in many of the cited eases, and we shall not attempt any review thereof.
It is true that the top of the bank was much higher than the surface of the highway, and was not in the line of ordinary, travel, but Harold‘was not a trespasser thereon. Public highways are frequently used' by pedestrians, who . , „ , . ' . J f ' might find it convenient to walk upon the bank, 0£ way of automobiles and other vehicles traveling upon the right of way. The box was shiny, and presented an attractive appearance to a boy of tender years. He did not and could not reasonably be expected to comprehend or know the deadly character of dynamite caps, and nothing was more natural than that he should attempt to remove all foreign substance therefrom and to use the cap for some purpose that would serve his youthful fancy.
The proposition most strongly urged is that there is nothing in the evidence to show that any act or negligence on the .part of appellant, its servants, or employees was the proximate cause of the injuries. There was, however, no other intervening or independent cause except the attempt of .Harold to remove the dangerous substance from the cap. This was one of the very things which appellant was bound, reasonably, to anticipate and guard against. It was not an intervening independent cause, but the direct and proximate result of the placing or abandonment of the caps at *1344tbe place where found and the appropriation thereof by Harold. He was at the time a few days under ten years of age. Any traveler upon the highway observing the box lying on the bank might have an inclination to pick it up and look for its contents. One of mature years would, of course, apprehend the nature of the substance, and would not have been injured, but not so as to children, whose lack of maturity and experience leads them to go further in their investigation and find out all about the cap. The issues of negligence and the question of proximate cause were, under the facts disclosed, in our opinion, questions for the jury-
II. A question was raised as to the competency of Harold as a witness, who, at the time of the trial, was eleven years of age. After questioning of him by the court, the objections to his competency were overruled, and we think properly so. During the further progress of, the trial, a colloquy arose between court and counsel, growing out of an objection to the admissibility of certain testimony offered by appellant to show that the box might have been left on the embankment by other construction companies engaged in work of similar character in the vicinity. The court ruled that the evidence should be confined to contiguous territory. Exception was taken to a remark of the court’s during the colloquy with counsel. What was meant by the remark was fully explained to the jury, and any prejudice occasioned thereby removed. In this same connection, it is coh-tended that the remarks of counsel for appellees were prejudicial. The criticism is without merit.
The remaining assignments are based almost wholly upon exceptions to the court’s instructions.
III. The first of the exceptions to be considered is to the statement of the issues by the court to the jury. There is some merit in the contention of counsel at this point, but the failure to more accurately state and define the issues eould not reasonably have misled the jury, and a reversal would not be justified upon this ground. It is always the better practice for the court to briefly and succinctly state the issues in its own language, and to clearly set forth the several propositions necessary to a recovery and to be established by the plaintiff by a preponderance of the evidence. This is, however, frequently not done, and perhaps it is *1345not always convenient or possible for the court to do so. The court further instructed the jury that the finding of the box by Harold at the place indicated by the testimony, the throwing away, and the recovery thereof by the father, the injuries, and the manner in which they were received, and some other facts were established by the undisputed evidence. The instruction was correct, as this evidence was in no wise disputed by other evidence, direct or indirect.
The court also instructed the jury that Harold was not a trespasser, whether using the highway for the purposes of the errand on which he was sent or for play. The objection to this instruction is that there was neither evidence nor claim on the part of appellant that the boys were on the highway for the purpose of play- . . , ,, , , mg. There was no issue as to the boys playing on the highway, nor does the evidence tend to show that a trespass was committed. The law embodied in the instruction is correct, and the reference to children’s playing upon the highway was by way of illustration, and without prejudice.
It is also contended by ceunsel for appellant that the cause of action stated in the petition ~s based upon the attractiveL nuisance doctrine, and that the court confused the jury by not more clearly stating the issues, and in submitting the case upon a theory wholly at variance with the allegations of the petition. The petition is susceptible to the interpretaiion placed thereon by appellant, but the allegations thereof are also consistent with the theory upon which the case was submitted to the jury. The attractive-nuisance doctrine, as usually defined and applied, is not involved in this case. The court submitted the case to the jury on the theory of common-law negligence. The negligence of appellant was in placing or leaving the explosive exposed at the place described. The character of the box containing the same was material only as it may have tended to more readily attract attention, and thereby tend to increase the hazard. The duty of one handling, using, or storing explosives is fully discussed and decided in the numerous cases cited herein. The basis of liability is well and clearly established. The ref erence in Instruction No. 15 to the box in which the caps were inclosed could not have been prejudicial, even if erroneous. *1346What we have said sufficiently disposes of all assignments based upon alleged errors in the court’s charge to the jury.
IV. An affidavit by one of the jurors was attached to ap-, pellant’s motion for a new trial. The affidavit was stricken by-the court. We shall not copy nor state the contents of the affidavit, further than to' say that it was clearly incompetent for any purpose. Affidavits which tend to stultify the juror, or relating to matters necessarily inhering in the verdict, will not be accepted as a cause for setting the same aside.
We have referred to all of the principal questions argued by counsel, but have omitted a few points covered by the exceptions to the instructions, as well as other matters; blit they have all had the careful consideration of the court, and have been found without substantial merit. The judgment is — Affirmed.
