Don't ever approach a railway crossing without looking out for the engine while the bell rings, and listening to see if the train is coming; for there is good sense as well as good law in the suggestion of Chief Baron Pollock, that a railway track _per se_ is a warning of danger to those about to go upon it, and cautions them to see if a train is coming. And our court has decided that when one approaches a railway crossing he is bound to keep his eyes open, and to look up and down the rails before going upon them, without waiting for the engineer to ring the bell or to blow the whistle.[98] It is a duty dictated by common sense and prudence, for one approaching a railway crossing to do so carefully and cautiously both for his own sake and the sake of those travelling by rail. If one blindly and wilfully goes upon a railway track when danger is imminent and obvious, and sustains damage, he must bear the consequences of his own rashness and folly. [98] 12 Met. 415. Don't drive horses or other animals affected by contagious diseases on the public way, or allow them to drink at public watering-places, or keep them at home, for that matter. The common law allows a man to keep on his own premises horses afflicted with glanders, or sheep afflicted with foot-rot, or other domestic animals afflicted with any kind of diseases, provided he guards them with diligence and does not permit them to escape on to his neighbor's land or the public way. But under the statute law of this State, a man having knowledge of the existence of a contagious disease among any species of domestic animals is liable to a fine of five hundred dollars, or imprisonment for one year, if he does not forthwith inform the public authorities of such disease.[99] Aside from the penalty of the statute law, it is clearly an indictable offence for any one to take domestic animals affected with contagious diseases, knowing or having reason to know them to be so affected, upon the public ways, where they are likely to give such diseases to sound animals; and he would be answerable in damages, besides.[100] [99] St. 1885, c. 148. [100] 2 Rob. N.Y. 326; 16 Conn. 200. If you are afflicted with a contagious or infectious disease, don't expose yourself on a highway or in a public place; and don't expose another person afflicted with such disease, as thereby you may jeopardize the health of other people, and your property also, in case you should be sued by some one suffering on account of your negligence.[101] [101] 4 M. & S. 73; Wood on Nuisances, 70.
