In school, church, and society many things are taught by the prohibitory don't; and thus many rules of law relating to public and private ways may be taught and illustrated in the same way. For instance:—

Don't ever drink intoxicating liquor as a beverage, at least in large quantities. If you ever have occasion to use it at all, use it very sparingly, especially if you are travelling or are about to travel with a team; for if you should collide with another team, or meet with an accident on account of a defect in the way, in a state of intoxication, your boozy condition would be some evidence that you were negligent. The law, however, is merciful and just, and if you could satisfy the court or jury that notwithstanding your unmanly condition you were using due care, and that the calamity happened through no fault of yours, you would still be entitled to a decision in your favor; but when you consider how apt a sober human mind is to think that an intoxicated mind is incapable of clear thought and intelligent action, I think you will agree with the decisions of the courts, which mean, when expressed in plain language, "You had better not be drunk when you get into trouble on the highway."[97 ]

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.

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 ]

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 ]

When there is snow on the ground, and the movement of your sleigh is comparatively noiseless, don't drive on a public way without having at least three bells attached to some part of your harness, as that is the statute as well as the common law. By the statute law you would be liable to pay a fine of fifty dollars for each offence. And by the statute and common law, in case of a collision with another team, you would probably be held guilty of culpable negligence and made to pay heavy damages. Of course you would be allowed to show that the absence of bells on your team did not cause the accident or justify the negligence of the driver of the other team, but it would be a circumstance which would tell against you at every stage of the case.[102 ]

If you have no acquaintance with the nature and habits of horses, and no experience in driving or riding them, don't try to ride or drive any of them on a public way at first, but confine your exercise in horsemanship to your own land until you have acquired ordinary skill in their management; for the law requires every driver or rider on a highway to be reasonably proficient in the care and management of any animal he assumes to conduct through a public thoroughfare.[103 ]

Don't ride with a careless driver, if you can help it, because every traveller in a conveyance is so far identified with the one who drives or directs it, that if any injury is sustained by him by collision with another vehicle or railway train through the negligence or contributory negligence of the driver, he cannot recover damages for his injuries. The passenger, in law, is considered as being in the same position as the driver of the conveyance, and is a partaker with him in his negligence, if not in his sins.[104 ]

If you have a vicious and runaway horse, and you know it, you had better sell him, or keep him at work on the farm. Don't, at any rate, use him on the road yourself, or let him to other people to use thereon; for if in your hands he should commit injuries to person or property, you would have to foot the bills; and if he should injure the person to whom you had let him, unless you had previously informed him of the character and habits of the horse, you would be liable to pay all the damages caused by the viciousness of the horse. If you should meet with an accident by reason of a defect in the highway, you could not recover anything, however severely you might be injured or damaged, provided the vicious habits of the horse contributed to the accident.[105 ]

In riding or driving keep hold of the reins, and don't let your horses get beyond your control; for if you do your chances of victory in a lawsuit will be pretty slim. If you tie up your reins for the purpose of walking in order to get warm or to lighten the load, and let your horses go uncontrolled, and they run over a child in the road and kill it or seriously injure it, you will probably have to pay more than the value of the horses, unless they are very good ones. Or if, going thus uncontrolled, they fail to use due care and good judgment in meeting other teams, and in consequence thereof damages occur, you would be expected to make everything satisfactory, because your team is required to observe "the law of the road" whether you are with it or not, especially if you turn it loose in the highway. Even if you have hold of the reins, and your horses get beyond your control by reason of fright or other cause, and afterwards you meet with an accident by reason of a defect in the highway, you cannot recover anything.[106 ]
