1 notTwar-TIONS: píeadfngsor ■ proof' I. The grounds on which plaintiff seeks to recover, briefly stated, are: (1) That the highway was obstructed by the car; and (2) that the team took fright at said car. In the seventh and eighth paragraphs of the charge, the court, in substance, instructed the jury:
‘ ‘ And if you further find, from all the evidence, that said car, placed and left where you may find from the evidence it was placed and left, was an object apt to frighten horses of ordinary gentleness, * * * then you would .be warranted in finding that defendant was guilty of negligence.”
We think this instruction was erroneous, for the reason that it was not alleged that the car, placed as it was, was apt to frighten horses of ordinary gentleness. The only material questions were: Was' the highway obstructed by the car, and did the horses become frightened at the car ? and not whether horses of ordinary gentleness were apt to become so. There was no such issue, and there was no evidence introduced tending to establish such fact. The recovery must be obtained on the grounds stated in the petition, and not on another and different ground. Manuel v. Chicago, R. I. & P. Ry. Co., 56 Iowa, 656. See, also, Gilbert v. Flint & P. M. Ry. Co., 51 Mich. 488 ; s. c., 16 N. W. Rep. 868 ; O’Donnell v. Chicago, M. & St. P. Ry. Co., 69 Iowa, 102.
II. There was evidence tending to show that the horses driven by Bolton became frightened at or when *426crossing- a bridge, and that lie whipped them, which caused them to run, and that they were unmanageable, and beyond his control, before and at the time he reached the crossing. The court instructed the jury as follows :
“If you find from the evidence that, before reaching the crossing, said Bolton’s team became unmanageable, and ran away, either from fright or whipping or both, and, while running over said crossing, they shied at the freight car standing at or on said crossing-, and caused the accident, then the. in jury was not caused by any negligence of- defendant, unless the j ary find that such accident would have occurred if said team had not become so frightened or run before reaching said crossing.”
The evidence tended to show that the highway was fifty feet wide, and that planks were laid down across it, and that the travel crossed on said planks, which were twelve or fourteen feet long, and that the car stood on, or the bumper projected some distance, not exceeding three to five feet, over the planked way. . Counsel for appellant contend that the latter portion of the foregoing instruction is erroneous, and their position must be sustained. There is not a single fact or circumstance in the case upon which such portion of the instruction can be properly based. There was sufficient room for the team to have passed over the plank-way, although the car projected over it; and if the team became frightened, was whipped, and was beyond control before reaching the crossing, there is no evidence tending to show that the accident would have occurred if the team had not •become so frightened.
III. The court instructed the jury: “In determining the amount of the recovery you may find the plaintiff entitled to, you will also consider the age and capacity of said Bolton, at the time of the accident, to work, his business, the amount of his earnings and his capacity to earn money.” Bolton was seventy-two years old, and a farmer, but there was no evidence tending to show his earnings, except *427that Bolton testifies that the accident “knocked off forty per cent.” of Ms ability to labor ; but this has no tendency to show his earnings either before or after the accident. Gardner v. Burlington, C. R. & N. Ry. Co., 68 Iowa, 592.
‘ indefinite special^ inter-IV. The court submitted certain interrogatories to the jury, which, and the answers thereto, are as follows : “ (1) Did Bolton see the freight car standing on the north side-track, and the situation of said car, before he drove his team upon the tracks ? A. He saw the car on the north side-track. (2) Was said freight car, and its actual position, in open and plain sight to Bolton before he drove upon defendant’s tracks? A. As to the actual position we cannot say. * * * (5) Was Bolton’s team a young team, liable to become frightened at cars standing on or near the highway? A. Colts about as other colts. (6) Do you find that Bolton’s team was a safe one to drive past freight cars in the manner it was actually driven ? A. As safe as ordinary colts. * * * (8) Was Bolton’s team one of ordinary gentleness in respect to becoming frightened at cars standing in, or partly in, the highway? A. Yes ; for a young team.”
The defendant filed a motion for a new trial, on the ground, among others, that the answers to the second, fifth, sixth and eighth interrogatories are un'certain and evasive. If the evidence was insufficient to enable the jury to answer the interrogatories in the affirmative, a negative answer should have been given in clear and decided language. There is no escape from the conclusion that the jury could and should have responded by simply saying “Yes” or “No.” Had this been done, the legal effect of such findings could have been deter* mined; but there is no legal standard by which the effect of the foregoing answers can be ascertained, and-whether they accord or conflict with the general verdict it is impossible to determine.
Counsel for the appellant insist that it affirmatively appears that the plaintiff cannot maintain this action, because he is not a real party in interest; and it is *428insisted that be cannot recover, because Bolton was guilty of contributory negligence; but, as tbe evidence may not be tbe same on another trial, no beneficial result would be obtained by determining sucb questions now. There are errors assigned on rulings of tbe court in admitting and rejecting evidence which will probably not occur on another trial, and are therefore not determined.
