to look at it; you can do that with the very best kind of rails. they would have a man pass over there, as he says, two or three times a week, and look over everything. he does that with the very best kind of rails. when these rails get old and are liable to break, much closer care ought to be taken. i would not be prepared to say what they ought to do in a case like this. if a rail be forty years old, perhaps they ought to send a man around every day to hammer it. i do not say that this would be their duty.
