At the time of the injury Palmer had been employed in the yard of the defendant, in the City of Dubuque, 1. KEGiiTofetrcE: personal mju-l'*cs. about three weeks, coupling cars and assisting to . ° . ° make up trains. He received the mj ury of which he died, in an attempt to couple a National Line car to the tender of engine number 154. The evidence tended to show that this engine had been in the yard of defendant about ten years, and that National Line cars came into the yard daily, that they and the tender of engine number 154 were constructed with deadwoods, which came very close together when the draw-bar failed to enter the draw-head, and that, in consequence, the coupling of a National Line car to the tender in question was very dangerous, and could be accomplished in safety only by standing outside of the deadwoods, a distance of two or three feet from the center of the drawliead.
Defendant asked the court to instruct as follows:
II. The defendant also asked the court to instruct as follows : “ 14. If a brakeman on a railroad knows that tlie materials with which he works are defective, and continues his work without objecting, and without being induced by his master to believe that a change will be made, he is deemed to have assumed the risk of such defects; for the continuance of the brakeman in the employment is purely voluntary, and if he so continues without objection, with knowledge of defects in machinery, he is presumed to have waived the right to insist upon indemnity for injuries resulting from such defects.”
“ 16. The law presumes the compensation paid a person employed as a brakeman on a railroad is, in part, a consideration for the risks, hazards and dangers ordinarily incident to that service.”
“ 19. To entitle the plaintiff to recover in this action, the plaintiff must prove to the satisfaction of the jury, or else it 2.-: —-. bimlen o£ proof. must otherwise appear in the evidence to the sat- , . -, , .. isfaction of the jury, that the deceased was injured by the negligence of the defendant, whilst the deceased was observing ordinary care on his part to avoid injury, or did not by his own negligence contribute to the injury.” These instructions should have been given. The principles which they involve have been recognized by this court, and are abundantly sustained by authority. See Kroy v. Chicago Rock Island & Pacific R’y Co., 32 Iowa, 357, (361,) and cases cited. Muldowneg v. Illinois Central R’y Co., 39, Iowa, 615, and authorities cited; Greenleaf v. Illinois Central R’y Co., 29 Iowa, 14, (46,) and cases cited. It may be that a full and critical examination of the instructions given would discover that the principles of these instructions were sufficiently embodied in the charge of the court, and that, for the refusal to give these we would not feel inclined to reverse, if no other error existed.
It is objected that this shifts upon defendant the burden of proving the contributory negligence of the deceased. "We do not think the instruction vulnerable to this objection. The instincts prompting to the preservation of life are thrown into the scale as evidence, like the presumptions of sanity and innocence. But when the whole evidence is considered, these instincts included, the plaintiff cannot recover unless the preponderance of the evidence is in his favor.
That a party can recover with less than a preponderance of testimony, and at the same time have the burden of proof, involves an evident contradiction. The principle of this instruction is recognized in Greenleaf v. Illinois Central R’y, 29 Iowa, 14, (48.) See also, Allen v. Willand, 57 Penn., 347; C. & P. R. R. Co. v. Rowen, 66 Penn., 399; Northern Central R. R. v. Geis, 31 Maryland, 367.
IY. The plaintiff introduced as a witness A. A. Walcott, who amongst other things, testified as follows:
Q. “ State whether with National Line cars equqiped as that car is, with a tender equipped as that tender is, is that as safely coupled as ordinary tenders?
A. No Sir, it is not.
Q. State whether those tendei’S, equipped as that is, can be safely used in making coupling with a car equipped as that National Line car is?
A. I always considered those National Line cars very unsafe. A man has got to look out very sharp so as not to get caught. Think they are not safe.”
Plaintiff also introduced J. M. Way, who testified as follows:
A. No Sir, they are not.
■ Q. State whether this particular kind is safe or unsafe, for a man to make up a train of cars?
A. I call it very unsafe.”
All this testimony was objected to as incompetent. It seems to us that it all falls within the principle under which opinions 4. evidence: expert testimony. of witnesses were held incompetent in Muldowney v. The Illinois Central R'y Co., 36 Iowa, 462. (472.) The subject of inquiry, in this case was not such that unskilled persons would be likely to prove incapable of forming a correct judgment respecting it. Models of the tender and of the National Line car in question, were exhibited to the jury. Having the relations of the various parts explained the jury could have no difficulty in determining as to the danger which would attend the coupling of them. The matters inquired of are not proper subjects for the opinions of experts.
For the errors considered the judgment is
REVERSED.
