 Steer feeding, 11. H. McDowell {Nevada Sta. Bui. ^i, pl>- ^, 2^^^- 

 G). — With a view to learning the amount of alfalfa hay required for a 

 pound of gain, 4 steers were fed from December 11, 1897, to May 9, 

 1898. From the beginning of the test to March 2 thej" were given 

 alfalfa hay only, and from that date until May 9 cracked corn was fed 

 in addition to the hay. The steers had been on pasture without grain 

 previous to the test. During the test they were fed in box stalls. The 

 average results for the 2 periods follow:

Two days after the close of the test steers Nos. 3 and 4 were slaugh- 

 tered, the dressed w^eight being .56.6 and 56.49 per cent, respectively, 

 of the live weight. Steer No. 1 was fed until December 2, gaining in 

 this time 247.5 lbs. and consuming 6,262.25 lbs. of alfalfa hay, 174.5 

 lbs. of cracked corn, and 655.3 lbs. of bran. The dressed weight was 

 then found to be 61.7 per cent of the live weight. The feeding was 

 continued with steer No. 2 until May 7. In this time there was a gain 

 of 50 lbs., 473.9 lbs. of haj- and 104.5 lbs. of cracked corn being con- 

 sumed. The dressed weight of this steer was found to be 55.9 per 

 cent of the live weight.

 Continuing previous work, the author reports a test, conducted at Les- 

 "walt, of the value of turnips alone and supplemented by different con- 

 centrated feeds for sheep. The test, which was made with 6 lots of 

 20 .sheep each, began November 19, 1898, and covered 19 weeks. It 

 was divided into 2 periods of 9 and 10 weeks, respectively. All the 

 lots were fed turnips. In addition, lot 2 w^as fed maize, lot 3 oats, lot 

 4 equal parts of oats, dried distilleiy grains, and linseed cake, lot 5 

 dried distillery grains, and lot 6 linseed cake. During the first half 

 of the test half a pound per head daily of the concentrated feeding 

 stuffs was fed. Durino- the latter half of the test the oats and maize
