The first step, however, is in the selection of good stock, for by it the product of the herd is increased from twenty-five to thirty-three per cent., and, therefore, the profits must be immensely greater. The old plan of our forefathers of judging of the value of a cow by a crumpled horn and a large bag is now set aside by recent discoveries. The most important and most reliable one is that of Mons. François Guenon, of Libourne, France. After a series of experiments he was convinced there were outward marks in the hair which were an indication of the yield and quality of all cows. Patiently for many years he labored at forming his discoveries into a system, with classes and orders of each variation. He was finally rewarded by the approval of all the leading agricultural societies in France, and by that government with a pension of three thousand francs. The work of Guenon was partially translated and published in this country years ago, but it was his first crude effort, and it presented the new science in so crude a form as rather to dismay the learner than to invite him to master it. Last year the State of Pennsylvania appointed a commission of three well-known agriculturists and experts to test the system and report upon it. That report was printed and published to the extent of twenty-five thousand copies, which but partially supplied the demand. Messrs. Blight, Harvey, and Hazard examined the escutcheons of two hundred cows, and interpreted them as regards the quantity, quality, and time of the yield of each animal. Alongside of their statements the knowledge of the owner of each cow was printed, and it is truly wonderful how accurately the character of each cow is given by these gentlemen who had never seen the cattle before. The gist of their report was that the system was invaluable and worthy of adoption by every farmer, and such adoption would add millions of value to the improved herds of the country. 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.
