Upon the publication of this report, discussions took place in the leading agricultural journals, and thus has been created a demand for more easily to be acquired knowledge upon the whole subject. Willis P. Hazard, the secretary of the commission, has prepared a complete treatise upon Guenon’s system, and it has been just issued in a cheap form, for wide circulation.
Mr. Hazard in his book gives a sketch of the life of M. Guenon and the progress of his system, and then fully explains it, so that in this simplified form any one can quickly learn all the points so as to readily apply it. The opinions of others, both pro and con, are introduced, argued, and answered, so that in this volume one gets a full history and account of the system, and its practical application is made easy. There is a profusion of engravings, photographed from Guenon’s designs, which thoroughly elucidate the text and render it a valuable handbook which no farmer can afford to do without, and which amateur agriculturists will find a most interesting development of a wonderful discovery.—Philadelphia Inquirer.
“A gentleman well known among the dairymen, and who was appointed by the Governor of Pennsylvania to investigate the value and practicability of the Guenon system. He was induced to undertake the explanation of the system, which he has very ably performed in this volume. The low price at which it is offered should induce every one even in the smallest manner engaged in breeding or management of cows to procure a copy of it.”—American Farmer, Baltimore.
“At the New York State fair, in September, 1879, Mr. Hazard applied the Guenon system to a large number of cows of different breeds on exhibition, and told the amount of milk each gave, as indicated by the escutcheon theory. A committee, with Col. F. D. Curtis as chairman, was appointed to accompany him, and they state in their report that he was generally accurate, not varying in any instance more than two quarts in stating the daily average yield, and in most cases giving the amount exactly, and also the time the cows would give milk. He made his estimate on the average daily yield for the first three months after calving, on liberal feed. In one or two instances he over rated the cows, but generally where there was any difference he was under the amount stated by the owners. Mr. Hazard takes into consideration in his estimates the size of the cow and her whole contour, as well as the character of the skin. His round of observation is first the shape of the escutcheon, then the milk veins and quality of the skin. He offered to have the cows blanketed and then tell their milking capacity, but this was not done. It is fair to say that he judges mainly by the escutcheon. The tests attracted a large circle of breeders, who were greatly interested on account of the novelty and general accuracy.”—Col. Curtis in New York Tribune.
