Under· this statute it is the duty of the company to sound the whistle and ring the bell, as provided in the statute, at all highway crossings. In addition thereto, the company may be required to take further precautions to give timely warning of the approach of its trains, if, as I have already said to you, the circumstances are such that the sounding of the whistle and ringing of the bell, as provided for in the statute, would not alone be sutlicient to give timely warning of the approach of the train. On the other hand, persons who are about to cross a railroad track are bound, on their part, to exercise ordinary care and diligence to ascertain whether a train is approaching, and the precaution to be taken by them will vary according to circumstances. They know that the crossing is a place of danger; that a train may come by at any moment; and they are bound to make a vigilant use of their senses of sight and hearing in order to ascertain if a train is approaching. If the nature and surroundings of the crossing are such that an ap- proaching train cannot be readily seen or heard, this fact calls for the exercise of greater watchfulness and to taking of greater pre- caution on part of travelers who are about to cross the track in a ` wagon. It is the duty of the traveler to use proper care to ascertain whether he can safely pass upon and over the railway track. He is not justified in attempting to pass over the track if a train is approach- ing the crossing at such a rate of speed as to render a collision pos- sible. In order to ascertain whether he can with safety attempt to pass over the crossing it is his duty to exercise ordinary care and dil- igence to ascertain whether a train is or is not approaching; and if he fails to do so, and is injured in consequence thereof, he cannot recover therefor, even though the company may also have been guilty of negligence on its part. In the case now on trial it is not questioned that on the second day of November, 1884, one David W. Whitmer, with his wife, Mar- tha J. Whitmer, his son, Floyd Whitmer, and daughter, Matic Whit- mer, was passing in a wagon along the public highway which inter- sects or crosses the railway track of the defendant at a point about
