TIIIS ncw and authoritativc work dcals with thc subjcct in a scientific way and from a ncw vicw-point. Dr. Collins has dcvotcd his lifetime to the study of chaitging cconomic agricultnral conditions. “ Hack to thc soil ” was ncvcr a morę attracticc proposi-tion and ncvcr so worthy of bcing lieedcd as during tliesc opening years of the twentieth century. Farm life to-day ofTcrs morę inducements tlian at any prcvious period in thc world*s history, and it is calling millions from thc desk. The reason for this is not at first obvi«>us, and for this reason Dr. Collins has prepared the present work, which denionstrates conclusicely the debt which agricul-tnrc owcs to modern science and thc painstaking govcrn-nient and State ofiicials. Much of the drudgery of the old farm life has hcen donc away with by thc usc of improvcd methods, improved stock and carieties. All this tends to create wealth by inereased yaluc of the product and de-creascd cost of production. Irrigati n, the ncw fcrtiliza-tion, the ncw transportation, thc ncw creations, the ncw machinery, all come in for a share of attention. The illustrations are of spccial value, and are unicjue. All who arc in any way interested in agriculturc should obtain a copy of this most timely addition to the literaturę of agri-culture. A fuli table of contents, as well as sample illustrations, will be sent on application.
