In all the numerous contributions of Mr. Bilgram to the science of economics there is a praiseworthy evidence of thought and the desire to do justice to all sides of the question. His expression of his thought is unusually clear, and his argmnents have the ring both of a comprehension of this most difficult of subjects and of entire sincerity. F. CALCARO'S SYSTEM OF PI~A,iSI,'RVIN(; GREEN FORAGE WITHOUT ~--~EAT OR. FERMENTATION EY TIlE USE OF THE SILO GOVERNOR. By Samuel ~,V. Calcaro, Dover, Mass. Chicago, Howard & Wilson Publishing Company. I889 .
This book is devoted to a description and commendation of Mr. Calcaro's silo governor, which consists substantially of a system of perforated pipes disposed among the contents of the silo, by wlfich--in combination with pressure by a series of jack-screws--it is claimed that the air is displaced by carbonic acid, that fermentation is prevented and that the material in the silo remains in its original condition, but softened and fnlly soaked in its owr~ juices from the bottom to the top of the mass. The published recommendations speak very highly of the results attained and the nutritive character of the forag-e thus prepared. The theory and practice of Mr. Calcaro differ widely, it may be said radically, flom theory and practice presented and recommended by authorities generally recognized as good in this matter. It is not for this J~UttNAL to decide when the doctors in agriculture so disagree.
