“A very valuable pamphlet. Mr. Hazard has devoted great attention and study to the subject, with a view of rendering the system popular, and we happen to know that his work is largely appreciated, especially by the farmers of New England, from the number of orders received for the book. The discovery made by Mr. Guenon, and the practical principles founded on it are invaluable, and the saving to the country by its general knowledge will be very great. The State of Pennsylvania, in 1878, appointed a commission to test the system and report on it. Mr. Hazard was a member of the commission, and has added the results of much study and research. He has been invited to lecture and present the subject at the annual meeting of the Massachusetts State Board of Agriculture, at Greenfield, and has many invitations and engagements in other places.”—_Massachusetts Ploughman._ “This volume embraces all the essential matters in Guenon’s treatise. It is really a valuable contribution to dairy literature.”—_Southern Cultivator._ “Every farmer should study Guenon.”—_Farm Journal._ “Dairymen and stock raisers should send for a copy.”—_Rural Nebraska._ EXTRACTS FROM THE MUCH LARGER NOTICES OF THE WORK. HOW TO SELECT COWS; OR, THE GUENON SYSTEM EXPLAINED. By _Willis P. Hazard_. In no way is the march of improvement in agriculture more decided than in the new discoveries and new methods of developing its resources. It is owing to these that America is now the granary of the world, and, as years roll by, if the developments of the next decade are as great in proportion as the last ones, no matter how extensive the foreign demand, there will be an ample supply at still lower prices than at the present. No branch of agricultural interests has changed so much and received such an impetus, especially within the last five years, as the dairy. Entire new modes of making butter and cheese and of setting milk have largely taken place of the old ones. Competition in making dairy products becomes keener each year, and every process by which the labor can be lessened, or the products be cheapened, meets with recompense.
