farm fertilizers; and which illustrate by means of pot culture 

 and other indoor experiments. In addition to the laboratory 

 practice, which requires about four hours per week, the students 

 are required to observe and report upon the forty experiment 

 plots in the Experiment Field. While this does not in any 

 respect describe all of the laboratory work in any phase, it is hoped 

 that sufficient has been said to suggest the general nature of the 

 work as outlined in the course. 



Experiment Field. The Experiment Field consists of forty 

 plots each one square rod in area, and each surrounded with a 

 strip one-fourth of a rod in width. It is seen then that each 

 square rod thus surrounded is a unit in the general experiment. 

 Just enough of the plan of experimentation will be given here to 

 afford a general idea. The entire forty plots are divided into 

 two divisions each containing twenty plots, one division illus- 

 trates one type of agriculture called grain farming, and the other 

 division illustrates another type of agriculture called mixed, or 

 live stock farming. Each division is subdivided into four series 

 of five plots each. Upon the four series of each division, four 

 crops are grown each year in the rotation corn, wheat, oats, and 

 clover. With the exception of the first plot in each series, each 

 plot leceives treatment with one or several fertilizers according 

 to the plan. There are represented upon this small area forty 

 experiment plots each differing with the others with at least one 

 condition. Some very valuable data have been gathered from 

 this source within the two years of its existence and with in- 

 creased accumulations increased importance is to be attached. 

 It will be unnecessary to say that the Experiment Field is a 

 very valuable adjunct to the courses in agriculture. 



Agricultural Club. The club is formed of the young men in the 

 school who have an interest in agriculture. Membership in the 

 club is purely voluntary. The only qualification is sufficient 

 interest to attend the regular weekly meeting. There were fifty- 

 six members during the Spring Ouarter. The purpose of the 

 Club is to furnish an opportunity to express themselves freely 

 Upon such topics as may naturally rise in their general reading 

 and thinking. It further furnishes new matter for considera- 

 tion because definite subjects are proposed for discussion and 

 eacli member usually speaks with freedom. Its members assist 

 very materially in the rare 1 f the Exper'ment Field. This year
