many doors, offer ample means for obtaining fresh air, and at the same time, all 

 odors of the cattle are kept from the feed. The floors under the cattle are of 2-in. 

 oak, laid with lead joints, making them water tight. The manure gutters are 18 in. 

 wide, 6 in. below the floors on which the cattle stand, and 4 in. below the floor in 

 their rear. Length of floor for stock depends on size, from 4 ft. for yearlings, 4h ft. 

 for mature Jerseys, to 5 ft. for heavy steers. Feeding floor in front of all is 9 ft. wide. 

 Various means for confining the animals are used for illustrative purposes. . . . 



"Connected with the east wing, where the dairy cattle stand, is a small room to 

 receive the milk, prior to taking it to the creamery. It is fitted with a sink and 

 water supply, scales for weighing milk, bottle rack for samples of milk used in test- 

 ing, etc. In rear of all animals the sides of the building are all ceiled and 

 painted. . . . The stables are fitted with four manure carriers. " 



Connected with each end of the feeding passage is a circular wooden 

 silo of somewhat over 200 tons capacity, resting on a rock foundation 

 and having an earth floor. These silos were constructed with a special 

 view to making the sides air-tight. In each silo there are three 2 by 

 4 ft. doors opening into a chute connected with the feeding passage. 



Ample protection against lire is provided by tire hydrants and hose 

 in difl'erent parts of the liarn. 



Agricultural hydraulics, Vol. Ill, P. L. Salvador {Ilydraulique agricole. Paris: 

 Vve. a Duimd, 1900, Vol. Ill, pis. 4-S, pp. VIII +563, figs. ^75).— This is one of the 

 volumes of the Bihliotlieque du conducteur de travaux publia, published under the aus- 

 pices of the ministers of public works, agriculture, public instruction, commerce and 

 industry, interior, colonies, and justice, of France, and discusses, in their engineering, 

 agricultural, and legal aspects, sanitation and reclamation of swampy lands; warping; 

 reclaiming of soils beneath the level of the sea (polders); drainage of the soil; and 

 agricultural utilization of sewage. In the treatment of each subject the general prin- 

 ciples and conditions are discussed and notable examples of work in the particular 

 lines are described. The various laws of France relating to the subjects treated are 

 given. The book is a valuable compendium of information both for the engineer and 

 agriculturist, but its usefulness as a book of reference is seriously impaired by lack 

 of an index.
