Now, having laid out this programme, he does not say what was to be done with it. The inference was to be drawn, we suppose, that the many escutcheons were to be engraved, and the public were to draw their conclusions from them and the reports given by the owners and milkers, and see how Guenon would stand the test. And what were the believing or non-believing commissioners to do? Supervise the taking down of all this? How, at once, this shows Mr. Hardin to know little or nothing of the system! Like Mr. Reeder, he did not know that Guenon assigns many other things to be thought of to form a correct opinion! Was it more proof to be told by the owner all that any one could know about the cow, and then say that corresponds with the escutcheon? Or did it put the system to a severer test, to say to the owner, don’t tell me a word, and then proceed to tell him all about a cow you never saw, simply from examining her escutcheon? In one case, you are assisted to define the escutcheon by the knowledge given you. In the other case, you define the cow’s character by only the knowledge you can get from the escutcheon. No better proof can be given of Mr. Hardin’s lack of practical knowledge of the system. Another objection he makes, and repeats several times, as being a very strong one with him, is, why did not Guenon, and why do not the commissioners, go to work and buy up all the best cows and sell them at a profit, and thus get very rich. His cry is, why don’t they make plenty of money out of it, if it is so valuable? Simply, because neither of them are in that business, or care to be. But Mr. Harvey, a manager of the Delaware county almshouse, in one year from taking this position, changed the cows there, and increased the yield twofold from the same number of cows, and has bought and sold all the steers and cows on his large farm for many years solely by this system, and _has_ grown wealthy. He says in another article “feeling the modesty that naturally attaches itself to benighted ignorance,” he “started out in the city in search of some one who was learned on these subjects.” He found “a professor in our medical institute,” “one of our most learned physicians,” and they proceed together to canvass Professors Magne and Arnold’s theories and facts about the formation of the escutcheon. The result of two such wise heads (or of “benighted ignorance”) coming together, was that neither of them ever heard of Professor Magne, and that his dictum was “opposed to all the teachings of physiology.” The learned professor knowing as much about a cow as he did of physiology. And it is such stuff as this which forms the arguments of Mr. Hardin. Professor Salmon in his essay on Contested Dairy Questions effectually settles these “learned” men.
