Fattening mature steers on cotton seed and cowpea hay, R. L. 

 Bennett aud G. B. Irby {Arkansas ^ta. Bui. 31, pp. 3-11). — Two half- 

 grade 3-year-old steers were fed in box stalls for 90 days, begiuiiing; 

 January 23. Both received whole cotton seed and cowpea hay, the 

 amount being 13.G lbs. of seed and 20 lbs. of hay per steer. The steers 

 gained 270 lbs. and 274 lbs., respectively. They were bought at 2 cts. 

 per pound and were estimated to be worth 3J cts. at the close of the 

 trial. With cowpea hay at i " per ton and cotton-seed meal at $5, 

 there was a profit of $21.30 ior the 2 steers. 



**Two small l|-year-okl steers were fed for 35 days in the experiment in exact 

 manner of the 2 largo steers. They showed no had eflects whatever from the seed, 

 and made a daily average gain of 3.1 Ihs." 



Raising dairy bred calves, T. L. Hacker {Minnesota 8ta. Bui. 35, 

 pp. 82-92, fig. 1). — This experiment was made to compare the cost of 

 raising calver^ on whole milk, and on skim milk supplemented by flax- 

 seed meal, and to note the effects of these 2 rations on the thriitiuessof 

 the calves. Nine calves were used, 1 being fed on whole milk during 

 a period of 60 days, while 8 were gradually changed to skim milk and 

 flaxseed meal. The time covered by the trial varied from 12 to 24 

 weeks with the different calves. The food eaten, gain in weight, and 

 cost of the food per pound of gain are tabulated for each animal, and 

 an analysis is given of the flaxseed meal. The following table gives a 

 general summary of the results: 



Summary of feeding experiments with calves. 



"While the experiment was fairly satisfactory as to the general growth of the 

 calves, the details in feeding were not as carefully carried out as the importance of 

 the work required. It is therefore being repeated with a view of obtaining more 

 accurate data, though it can hardly be expected that our efiorts will result in grow- 

 ing a finer lot of calves." 



Effect of weather on the quantity and quality of milk, J. L. 

 Hills {Vermont Sta. Rpt. 1893, pp. 88-92). — Observations on this sub- 

 ject have previously been reported by this station in the Annual Beports 

 for 1891 and 1892 (E. S. E., 4, p. 491; and 5, p. 322). In addition to 

 these tests observations are here rejiorted on tv.'o other tests. The
