Cost of filling silos, L. Carrier {i. aS'. Dept. A(/r., Farnicru' Bill. 292. pp. i.T. 

 /7//S-. .1). — Data were gathered on 31 farms, la Jefferson and Fond du Lac coun-

 the nuniher and arrangement of men and teams, machinery used, and the length 

 of time taken in putting up silage. Measurements of the silos and other neces-

 men and the same for a team of 2 horses. Engine hire was rated at $4.50 per 

 day, including the engineer, twine at Hi cts. a pound, coal at $."1 a ton, and gaso- 

 line at 1.3 cts. a gallon. Wear and tear on machinery and l)oarding the help 

 was not taken into account. Ten hours were considered a day's work. The 

 cost jier ton of silage, as determined hy this investigation, varied from 40 to 80 

 cts. on the different farms. The average yield per acre was 0.1 tons, and the 

 average cost per ton of silage (34 cts. The average amount of silage cut daily 

 per man was 4.0 tons, and the average cost per acre for putting the corn in the 

 silo .$.5.98. The different factors wliich cause the cost per ton of silage to vary 

 are i)ointed out and discussed.
