out the use of tuberculin te.st is reported in detail. The importance of the tuber- 

 culin test is, however, insisted upon. The need of State legislation is discussed, the 

 author believing that stock iu New York are menaced by the lack of proper legisla- 

 tion, since herds are being infected by the introduction of cattle brought from other 

 regions where there are strict laws upon the subject.

AGRICULTURAL ENGINEERING. 



The loss of water from reservoirs by seepage and evaporation, 



L. G-. Carpenter {Colorado Sta. Bui. to, pp. 32, Jig. 1). — A record is 

 given of observations on seepage from a series of reservoirs near Fort 

 Collins in %he winters of 1895-96 and 1890-97, and on evaporation from 

 the reservoirs and from an evaporation tank. The results are discussed 

 in detail and summarized as follows: 



"The seepage losses may be great. In the lakes under measurement the losses iu 

 some cases were less than from evaporation alone. In some cases lakes maj gain 

 from seepage from irrigated lands, aud the gain may be more than the combined loss 

 from seepage and evaporation. In the cases where loss from seepage occurred, the 

 loss was at the rate of about 2 ft. in depth over the area of the lake per year. This
