The cow being a sensitive and capricious creature, is, oftentimes so easily offended that if the maid rise from her before the milk is all withdrawn, the chances are that she will not again stand quietly at that milking; or, if the vessel used in milking is taken away and another substituted in its place, before the milking is finished, the probability is that she will _hold_ her milk--that is, not allow it to flow. This is a curious property which cows possess, of holding up or keeping back their milk. How it is effected has never been satisfactorily ascertained; but there is no doubt of the fact that when a cow becomes irritated, or frightened from any cause, she can withhold her milk. Of course, all cows are not affected in the same degree; but, as a proof how sensitive cows generally are, it may be mentioned that very few will be milked so freely by a stranger the first time, as by one to whom they have been accustomed. There is one side of a cow which is usually called the _milking side_--that is the cow's left side--because, somehow custom has established the practice of milking her from that side. It may have been adopted for two reasons: one, because we are accustomed to approach all the larger domesticated animals by what we call the _near side_--that is, the animal's left side--as being the most convenient one for ourselves; and the other reason may have been, that, as most people are right-handed, and the common use of the right hand has made it the stronger, it is most conveniently employed in milking the hinder teats of the cow, which are often most difficult to reach on account of the position of the hind legs and the length of the hinder teats, or of the breadth of the hinder part of the udder. The near side is most commonly used in this country and in Scotland; but in many parts of England the other side is preferred. Whichever side is selected, that should uniformly be used, as cows are very sensitive to changes. In Scotland it is a rare thing to see a cow milked by any other person than a woman, though men are very commonly employed at it in this country and in England. One never sees a man milking a cow without being impressed with the idea that he is usurping an office which does not become him; and the same thought seems to be conveyed in the terms usually applied to the person connected with cows--a dairy-_maid_ implying one who milks cows, as well as performs the other duties connected with the dairy--a dairy-_man_ meaning one who owns a dairy. There can be but little question that the charge of this branch of the dairy should generally be entrusted to women. They are more gentle and winning than men. The same person should milk the same cow regularly, and not change from one to another, unless there are special reasons for it.
