170 SIXTEENTH ANNUAL REPORT. 



average gain of only one and one half pounds. The results 

 show that apples alone afford only a maintenance ration. 

 Several other tests on raw and cooked potatoes, "Union 

 grains," and mixed feeds are contemplated for this win- 

 ter. 



In order to secure a field with uniform soil conditions 

 suitable for crop and fertilizer experiments, the four acres 

 of ground, west of the dairy barn and adjacent to the 

 brook, has been laid off into thirty permanent one-tenth 

 acre plots, 217 feet eight inches long, and 20 feet wide, 

 with a two-foot alley-way between them, and into seventeen 

 one-twentieth acre plots, having the same width as the 

 tenth acres. To secure uniform surface drainage, each 

 plot has been plowed as a separate land, with dead furrows 

 coming in the alley-ways. Between every other plot a 

 three-inch tile drain is being laid at an average depth of 

 two and one half feet. The laterals empty into a four-inch 

 main, which runs parallel with the brook and across the 

 plots, 22 feet from their ends. This complete system of 

 tiled drainage is being installed this fall. 



An experiment to show the effect of lime on heavy clay 

 soils has just been begun. One half of each of the plots 

 mentioned above has received an application of newly 

 slaked lime at the rate of 40 bushels per acre. Only one 

 half of each plot was limed to show the effect, if any, on 

 whatever succeeding crop may be grown on the plot. 



One bulletin, No. 113, "Experiments in Pig Feeding," 

 was published during the year. Three others are now in 

 the course of preparation, i. e., "The relative cost and feed- 

 ing value of light and heavy oats"; " Underdrainage, " 

 with the results of our own work used as a practical basis; 

 "Field Crops," stating the results of the season's work 

 in all plot and field experiments.
