feeder gives his cattle. The Brookmont farms are located six miles north 

 of Odebolt in Sac county. Here Mr. Cook has 7,351 acres of land all 

 in a body. He has it divided into farms of one-half section each with 

 buildings and feed lots on each farm. Three of these feed yards lying 

 nearest the ranch headquarters were selected as the places for this exper- 

 iment. On farm No. 14, one-fourth mile west of the headquarters, three 

 loads were fed. On No. 3, one-fourth mile south, three loads were fed 

 and on No. 16, one-half mile east, five loads were fed. Yards of as near 

 the same size and with as near the same accommodations as possible were 

 selected. The object of the experiment was to determine the value, if 

 any, of feeding by-products and condimental foods for the production 

 of beef, and it was planned to feed eleven lots of cattle. Lot 1, on corn 

 alone, Lot 2 on corn and oil meal, Lot 3 on corn and cotton-seed meal, 

 Lot 4 on corn and gluten meal, Dot 5 on corn and gluten feed, Lot 

 6 on corn and germ oil meal, Lot 7 on corn and dried blood, Lot 8 on 

 corn and Iowa Stock Food, Lot 9 on corn and International Stock Food, 

 Lot 10 on corn and Standard Stock Food, Lot 11 on corn and grass. The 

 by-products and condimental foods were furnished by the following com- 

 panies: Old process oil meal was used, furnished by the Midland Lin- 

 seed Oil Co. of Minneapolis, Minn. The cottonseed meal by the Amer- 

 ican Cotton Oil Co., of Chicago. The gluten feed, gluten meal and germ 

 oil meal were furnished by the Glucose Sugar Refining Co. of Chicago. 

 The dried blood by Swift & Co. The Iowa Stock Food by the Iowa Stock 

 Food Company of Jefferson, Iowa, and the International Stock Food by 

 The International Stock Food Co. of Minneapolis, and the Standard Stock 

 Food by the F. E. Sanborn Co. of Omaha. These products were all de- 

 livered free of charge at Odebolt. Mr. Cook furnished the cattle, yards, 

 corn and roughage and they were fed under the direction of the experi- 

 ment station or rather under the direction of the companies furnishing 

 the food, that is as to the amount of grain and by-products or condimental 

 foods their respective lots were to have. But they were all to have the 

 same kind of corn and roughage. With this in view, 220 head of steers 

 were selected from some 500 head which Mr. Cook had running in his 

 stalkfields and on a light ration of snapped corn at the time. The steers 

 were very common grades, Angus, Hereford and Short-horns, two years 

 old. They were purchased by Mr. Cook from the Bartlett-Richards Cattle 

 Co. in western Nebraska. The 220 head were divided as evenly as con- 

 ditions would permit into eleven lots of twenty head each, each lot con- 

 sisting of one Hereford, four Angus and fifteen Short-horns, or steers 

 showing some evidence of such blood. This division was made two weeks 

 before the experiment began and the cattle were placed in their respec- 

 tive yards. This was done that they might become accustomed to their 

 yards and all be under practically the same conditions when the feeding 

 started. On the tenth, eleventh, and twelfth of March, each lot was driven 

 over the scales and an average of these three weighings was taken as 

 the starting weight. The feeding started on the eleventh. All the grain 

 feed that each lot had was carefully weighed, mixed and placed in labeled
