The plaintiff testified that he got upon the car from which he was thrown, at the intersection of Hyde avenue and Benton street; that the car proceeded south about three blocks to the place of the collision; that plaintiff was riding on the back platform; that the platform was rtsed for smoking; that passengers were not allowed to smoke in the car; that plaintiff was smoking at the time he was riding upon the car; that he stood about the center of the car with his back to the back of the vestibule, his elbows on the back window; that the speed of the car was from 25 to 30 miles an hour; that the street car collided with a seven-passenger automobile; that the .collision threw plaintiff from the car; that plaintiff saw the automobile before the accident; that the hell on the street car called his attention to the automobile coining; that it was the impact of the collision which threw plaintiff from the back end of the platform; and that up until the time of the impact the street car did not decrease its speed at any time.
On cross-examinatiou the plaintiff testified that he saw the motorman try to stop; that the motorman commenced grinding the hand brake when he first saw the automobile; that there was no air brake; that the car was about 120 feet from the point of collision when plaintiff first saw the motorman put his brakes on; that from the time the motorman put on the brakes to the time of the collision the motorman worked frantically at the hand brake; that he also during that time rang the bell; that the automobile was going 6 or 8 miles an hour; that both the automobile and car were moving at the time of the collision.
Fred Johnson, a witness for the plaintiff, testified that he saw the accident; did not think the street car slackened its speed at all before the accident; that the street car was running at the same rate of speed at the time of the accident as it had been before. Joseph F. Perry, a witness for the plaintiff, testified that the street car was running 25 miles per hour and did not cheek its speed from the first time the wit
At the trial the plaintiff thought it was material to introduce testimony as to the distance in feet at several points along Benton and Harmony streets at which an automobile and a street car would be visible to persons operating such vehicles respectively under the circumstances detailed in the evidence. For this purpose the witness Cook was placed on the stand and gave testimony as to measurements made by him, showing the various points along the two streets at which the occupants of the automobile and street car could have seen each other. It is claimed that it can be mathematically determined from the testimony of Mr. Cook that one of his lines where he claimed the vision was unobstructed ran through a two-story brick house marked on the diagram which the witness used. The accuracy and reliability of the testimony of the witness was a legitimate subject for argument before the jury, and it was for the jury, to give such weight to the testimony as in their judgment it seemed to be entitled. We see no error in the admission of the evidence of the witness Cook.
This court, in United States Smelting Co. v. Parry, 166 Fed. 407, 92 C. C. A. 159, in an opinion by Judge Van Devanter, now Justice Van Devanter, decided that a certain discretion is accorded the trial judge in respect of the admission or rejection of expert and opinion testimony, and his decision admitting testimony of that character ought not to be disturbed unless it plainly appears that the testimony was not calculated to aid the jury in reaching a correct conclusion and was calculated to prejudice their minds. A large number of cases are cited in the case referred to in support of the rule stated.
The admission of the following testimony by the witness Joseph F. Perry is assigned as error:
“Q. How fast would, you say this street car was running when you first saw it? A. I should judge it was going 25 miles an hour.”
This question was objected to by counsel for defendant as incompetent, immaterial, and irrelevant, and no sufficient foundation laid. The principal objection to the question was that Perry was not basing his opinion entirely upon a conclusion as to the speed of the car formed at the instant he saw it, but in part upon reflection and measurements made afterwards. The witness testified that, when he first saw the street car, it was about 96 feet north of the middle of the intersection of Harmony and Benton streets. He also testified that he had observed railroad trains and street cars as to their speed and testified that he was able to give an opinion as to the speed of the street car. We do not think there was error in allowing the witness to answer the question, leaving the weight to be given the same to the jury after full cross-examination upon the subject. Dorenzen v. United Rys. Co., 249 Mo. 182, 155 S. W. 30.
The court was requested to charge the jury that the speed of the street car was not the proximate cause of the accident complained of, and therefore the jury could not find the defendant company negligent on account of the speed at which the street car was running. To have given this instruction would have been practically to have directed a verdict for the defendant, which was not permissible as we have shown. The court was requested to charge the jury that it was the duty of the defendant through its motorman to use reasonable care to avoid a collision with the automobile.' This request did not correctly state the duty of the motorman under the circumstances so far as a passenger on the car was concerned, and therefore was properly refused.
We have carefully considered the other requests to charge and find no error in the refusal of the court to give the same, the jury being properly instructed by the court on its own motion as to the duty of those in charge of the áutomobile at the time in question.
There being no error in the record, the judgment below is affirmed.
