This is a suit for damages for personal injuries. On August 12, 1907, plaintiff, a drill-man employed in defendant’s zinc mine near Aurora, was hurt by a premature explosion under ground on a seventy-foot level while loading a drill-hole with a shot. Presently, he sued in the Lawrence Circuit Court, counting on negligence. The jury finding against him and judgment following, he appeals.

The pleadings. Charging he was a drill-man running a drilling’’machine in defendant’s mine and loading and firing shots in drill-holes, plaintiff complains in his petition for that (as defendant’s servant) he had been for a long time loading drill-holes with giant powder of forty per cent nitroglycerine; that defendant negligently and without notice to him changed the powder to a brand of fifty per cent nitroglycerine; that the fifty per cent sort was more sensitive to explosion, and more powerful than the forty per cent kind, requiring *365more care in manipulation (all of which, defendant well knew or might have known with due care); that a stick of fifty per cent powder was negligently" furnished to him by some of defendant’s other servants, which stick-had been negligently prepared in that its paper wrapping was broken and torn, and the hole for the fulminating cap was negligently made too big, so that the cap attached to the fuse was liable to fall out, come in contact with the walls of the drill-hole and explode the powder prematurely while loading the hole for firing; that an explosion and his injury happened while plaintiff, in the line of duty and exercising due care, was loading a drill-hole with said stick; and that such explosion and his resulting injuries were caused by said negligent change in powder, negligent failure to notify plaintiff of the change and the negligent way said stick was prepared for use as aforesaid.
The answer was a general denial, a plea of contributory negligence, that the accident was a casualty not to be anticipated and was one of the risks plaintiff assumed when employed as a miner. There is a further averment that the statute making employers of miners responsible to one servant for the negligence of his fellow is unconstitutional — but that feature of the answer is abandoned.
The reply was conventional.
The facts. -Summarized, the facts follow:
Plaintiff’s arm was crushed by a premature explosion of a shot on August 12,1907, the broken bones did not knit kindly when set, and, at the time of the trial in March, 1908, the arm was in a bad way. The extent of his injuries not being material to any present issue, the testimony in that regard may be omitted.
It is agreed on all sides that plaintiff wa's a miner of experience, commencing years before as a shoveler, then becoming a pick-hand and a helper at a drill; and finally a drill-man or cutter. That he knew the brands of powder used in mines, the dangers incident to using *366high explosives, and was an expert in their nse. As drill-man he ran a drilling machine, drilled holes for blasting in mines, loaded and shot his drill-holes, having a helper under him to fetch, carry and help generally. While plaintiff was under a foreman, yet the details of drilling, loading, firing, inspecting his drill-holes and the roof after'firing, were entrusted to him as part of his duties. Off and on he had worked for defendant since November, 1904 — the last time for a few weeks. Powder is furnished to drill-men in a .round form, like exaggerated firecrackers — called sticks. Each “stick” is, say, eight inches long and one inch in diameter. These sticks are stoutly wrapped with paper. A stick equipped with a fulminating cap attached to a fuse is called a “shot.” In loading a drill-hole for blasting in a mine, sticks of powder are put to the bottom of the hole, one on top of the other, and the last stick to go in is the shot. These sticks are put in one at a time by a tamping bar. The bar, in this instance, was a'gas pipe with a wooden plug in one end (the tamping end) ten or twelve inches long. As we gather, in the end of this plug is a projecting nail. The miner pushes this nail in the stick of powder and lowers it into the hole by the tamping bar. On this occasion, plaintiff, acting as his own boss, had drilled a group of holes and was loading one of them for firing. He had put three sticks in place in the bottom of one of said drill-holes eight feet deep and two inches in diameter, and was putting the fourth, the shot, in place when the whole charge exploded.
A shot is made by punching sideways a hole in a stick of a dimension suitable to hold a fulminating cap in position when inserted — the idea being to carry the loose end of the fuse up and out for firing and thereby explode the cap and charge. In this instance, when about to load the drill-hole with the shot, plaintiff found the cap lying near .by and out of the cap hole. Looking into the matter, he saw the hole was too big to *367hold the oa,p in place. Knowing this, he put the cap back in the cap hole and in handling the shot the cap fell ont again. Once more he pnt it back and it again came out presently as he was putting the shot in the drill-hole. He also noticed that the paper wrapping of the stick was torn at the cap hole. He had no knife to make a new cap hole and as he had used a shot of that kind three or four times before in his years of mining experience, he says he thought he could safely do it again. Accordingly, putting the cap back in the cap hole, he pushed the shot four or five feet down the drill-hole with his tamping bar. At that point, while engaged in ramming it home, the powder was touched off in some mysterious way. He did not know the cause of the explosion. Sticks of powder, including-' the shot, were furnished him shortly before the accident by defendant’s foreman, who sent them from the top of the ground to the working level.
On defendant’s part there was uncontradicted testimony on the cap hole and torn wrapper to the effect that one certain punch was used in making holes for all caps, and that if the hole in this particular shot was too big to retain the cap or the wrapper was tom the foreman who personally made the shot was not aware of it. The tear in the paper was not accounted for unless the speculation is indulged that it came from punching the cap hole. There was also unquestioned proof that if the cap hole was too big to retain the cap, or if the paper was tom so that powder would leak out, then, either increased the danger. This, because the drill-hole was in flint formation and if escaped powder got on its sides through such leak, it might explode in several ways. For instance, a spark from the friction of the iron tamping rod; or a cap loose, out, dangling or pinched, might explode the powder. similarly — the very office of the cap being to explode. the powder. Plaintiff had made shots himself,knew of all the aforesaid dangers as an expert powder *368man, and, without asking for another shot as he might have done, assumed to use the one he knew was in bad condition. He, as said, justified himself in that use by saying that in his several years experience he had done so three or four times safely. There was also cogent and unchallenged testimony that the use of such a defective shot, with a loose cap and torn wrapper, was not proper care on the part of a miner. He might do it three or four times and the fifth result in an explosion from friction against the sides of the drill-hole. Plaintiff knew a jar or spark would explode powder and that light tamping was necessary even when sticks were in perfect condition. In this instance he said he was as careful as he could be — as careful as anybody could be. While there was testimony that sticks of powder with a high percentage of nitroglycerine were more sensitive to explosion than those of less, yet in the case in hand plaintiff said he was as careful as he could have been if there had been seventy-five per cent of nitroglycerine. Recalled to the stand later, he testified that if he had known the shot was Red Cross powder he would not have used it in its then condition, because that brand is more “treacherous” than any other of the same per cent. There was other testimony to the effect that Red Cross powder was more sensitive to explosion than any other in use by Aurora miners.
There was testimony, too, that it was customary for miners to investigate individually the powder they used, the strength of the powder having to do with the amount of work done, and miners look to the strength of the powder and govern themselves accordingly in the use of it. Plaintiff further testified that when he went to work for defendant at the outset the last time of his employment, he looked into the “powder box” (we infer, a box used to store sticks) and discovered the brand in use in the mine to be that known as forty per cent Independent. Powder of that *369brand was marked with the letter E; there was another Independent brand marked D having fifty per cent nitroglycerine, In Bed Cross powder the per cent is printed on the sticks. Plaintiff did not notice the label or marks on the exploded shot, it might have been Independent, either forty per cent or fifty per cent, he said, for all he knew. By other employees, by the powder dealer and his books, it was shown that the only powder in nse by defendant at the time, and that had been used for several weeks before the accident, was the fifty per cent variety, known as Independent D. The record shows that if there was a change in powder plaintiff was not informed of it and he said he knew of no change in point of. fact. It further appears that if there was any change in powder from Independent to Bed Cross, it was made by the dealer on his own hook and defendant itself was not informed of the fact. However, the dealer who furnished all the powder used by defendant denied any change. Plaintiff had a miner’s lamp in his hat and the marks on the sticks of powder were of such sort that he could have discovered a change by looking. There is, as already noticed, a brand of giant powder known as Bed Cross used in mining. There was testimony tending to show that Bed Cross powder has a peculiar brand on each stick and that it is more powerful than other powders of the same per cent of nitroglycerine, and more sensitive to explosion. The deposition of a miner was read, a fellow workman of plaintiff. He testified that the powder used by plaintiff at the time of the explosion he thought was Bed Cross. It seems, however, that he did not see the powder actually used by plaintiff and merely supposed it was Bed Cross. He judged from the powder in use afterwards. This witness, testifying in that behalf without regard to dates, said the per cents marked on the powder boxes were forty and fifty, that if defendant ran out of one it used the other, *370and that the foreman said they paid the price of fifty per cent powder and got only forty per cent strength. •The best we can make out of his testimony is that while he “thought” they were using Red Cross at the time, he did not know. He also said that plaintiff could have told the difference between Red Cross and Independent if he had looked at the sticks while handling them. Defendant’s foreman, who personally made up-the shot in question, testified that Red Cross was not used at the time, but Independent D, the same in use right along. As to Red Cross, plaintiff further testified he had handled it of a fifty per cent grade theretofore in other mines, that he wanted the jury to understand that at the time of the explosion he was as careful as he had been when theretofore he handled fifty per cent Red- Cross and was “just as careful as he could, home been” — as careful as if it had been seventy-five per cent nitroglycerine.
Twice, once at the close of plaintiff’s evidence and again at the close of the case, defendant unsuccessfully asked instructions in the nature of demurrers to the evidence.
The questions here are three, viz.: Defendant insists that, on the whole record, plaintiff was not entitled to recover as a matter of law. While for plaintiff error is assigned for that incompetent testimony was admitted .and. an improper instruction given for defendant.
We are of opinion plaintiff made no case for the jury, hence errors, if any, in admitting testimony or instructing the jury on behalf of defendant, do not materially affect the merits. This, because:
(a) Instructions to the jury or the admission of testimony for defendant touches merely the way the case is- put to the jury; hence, when-an appealing plaintiff’s case is challenged, as here, he must have made a case at the trial to put to the jury before he is heard to complain of the way it was put to them. In the prac*371tica] administration of justice, it is a plaintiff who has a case, not one who has none, who has a real grievance on bad advice to the jury or on lame proof by his adversary. The logic of the matter, then, is that if on the facts of the record a court can say as a matter of law that the end reached at the trial was the only end that could be rightly reached, plaintiff can not be injured (within the meaning of that word in the law) by improper testimony or too favorable instructions for defendant. When well looked to this doctrine accords with good sense and the intendment of our statutes; for one statute prescribes that error to be reversible in a' civil action must affect the substantial rights of the adverse party (R. S. 1909, sec. 1850) ; and another, that reversible error in a civil case is error materially affecting the merits (Ibid., sec. 2082). On those two commandments hang a substantial part of the law of appellate duty. Since the law-giver has said in so many words that not all error but only a certain kind is reversible error, it behooves a court whose function it is to enforce the written law between man and man, to see sharply to it that it leads the way by setting a good example in obeying the written law on its own duty. Paul, a sound lawyer, laid that doctrine down on a dramatic occasion — Acts xxxiii:3. In establishing a working theory in the premises, the stiff rule has come to be: No case for plaintiff, no merits or substantial rights. No merits or substantial rights, no reversible error of which plaintiff can complain. That rule is steadily adhered to. [Moore v. Railroad, 176 Mo. l. c. 545; Bradley v. Tea and Coffee Co., 213 Mo. l. c. 325; Mockowik v. Railroad, 196 Mo. l. c. 568; Schuepbach v. Gas Co., 232 Mo. l. c. 611-2; Whalely v. Coleman, 113 Mo. App. l. c. 600.]
(b) The specifications of negligence are two:
First. A negligent change of powder — a change without notice to plaintiff.
Second. A negligent preparation of the “shot.”
*372(1) As to the first, there is a failure of substantial proof. The change is said to be from forty to fifty per cent powder. The proof, as distinguished from conjecture, runs all one way, viz., that plaintiff was using the same kind of powder he had been. True there is a notion indulged by one witness that Bed Cross powder was substituted, but, when sifted, his testimony amounts to no more than a supposition — a thought. Suppositions are without legal efficacy. They are fanciful conceits thrown off as freely by the human mind, as are threads for its web by a spider, and about as inconsequent. So, the petition says nothing about Red Cross, a powder earmark hardly escaping the pleader if a fact. We think the notion of substituted Red Cross smacks of makeweight, mere flotsam and jetsam. We lay it out of view.
(2) As to the second, there is some testimony tending to show that when the shot was furnished by the foreman it was in bad condition, i. e., the cap hole was too big for the fulminating cap, and,' according to what plaintiff saw, there was a rent in the wrapping of the stick where the cap hole was punched; but whether that rent was there when the shot left the foreman’s hands, or came there by some inadvertence in the mine, is left somewhat dark. Those defects self-evidently increased the hazard of loading drill-holes and furnish a likely cause for explosion. If, now, plaintiff had not timely known of the imperfect shot and increased hazard, we would have an entirely different case to deal with. But in point of fact he knew more in that regard than the master. For instance, he knew that particular cap would not stay in that particular hole but would come out in loading. The master did not know that pregnant fact, nor did the servant think worth while to inform him of it. The drill-hole was in flint formation and by pinching or rasping or tamping there might be a spark in loading because of the flint formation. The master knew nothing of that ac*373tual drill-hole. It would not do to hold that the knowledge of the servant in those particulars should not he reckoned with in determining the liability of the master.
Knowing all these things, this unfortunate plaintiff, without a particle of necessity for doing so, and with a contempt for peril born of working in its ever present shadow, chose to use the imperfect shot when he could have had another for the asking. Wherefore? There is nothing in the case warranting the conclusion this master expected him to use an imperfect shot. Observe, too, the plaintiff neither sought nor relied on the master’s advice in that behalf. He trusted to his own judgment. He knew that using blasting powder was inherently dangerous at all times and at best. He knew the hazard was two-fold inflamed by using a leaking shot which had a loose cap likely to come in contact with the rough walls of the drill-hole and prematurely explode the charge. A servant is not a “mere machine.” [Bowen v. Ry. Co., 95 Mo. l. c. 277.] The master need not either actually or constructively hover over every transaction to keep the servant from hurting himself at his work by an act sounding to folly. He may rest somewhat on the fact that the servant has eyes, reasoning faculties, experience, knowledge in his trade. The master pays him to use them all. So, the servant, in the very act of hiring, agrees that he will. [Forbes v. Dunnavant, 198 Mo. l. c. 209.] Mine owners may intrust the details of inspecting drill-holes and the loading and firing of them to drill-men. [Knorpp v. Wagner, 195 Mo. l. c. 663, and cases cited.] And when such a servant, in effect his own boss,, pro hac vice, knowing the true facts and more than the master knows, voluntarily selects his own course in loading a drill-hole, when other courses are open and when he knows (as this one did) that he took his own life in his hands in the choice he made to confront a known danger, I think there is *374neither reason nor authority for putting the responsibility for the to-be-expected result on the master; for that danger was glaring, imminent and such as no reasonably prudent man should take at another’s risk-absent a command from the master. When he took it, it was at his own, not at his master’s. Whether, then, the doctrine of assumed risks or of contributory negligence be invoked, the result is the same as the law of negligence is now administered in this jurisdiction.
Respondent’s counsel cite a line of cases on all-fours, holding there is no legal liability under the facts of this record. They may be looked for in the head-notes of our reporter. We will not swell this opinion by listing them or quoting from them.
In the view announced, errors assigned by appellant are immaterial. Let the judgment be affirmed. It is so ordered.
All concur, Graves, P. J., in separate opinion.
