400 lbs. of nitrate of soda per acre, and the light <>t 1.62 tone with 600 lbs. per 

 acre of land plaster. No second crop was cut in either 1909 or 1910. The 

 effect of lime has not been apparent on any of these plots, either in connection 

 with the various chemicals used or on the "no fertilizer" plots. 



This project has been very seriously interfered with by the recent moving 

 of the railroad tracks, it being necessary to abandon eleven of the original 

 plots and replace them by others in an adjoining field. The soil of these new 

 plots is similar to that of the old ones and the grass was sown the same year, 

 i. c, 1905. The now plots are being underdrained like the old oiks this fall. 

 The following table will show the comparative average yield of hay from the 

 plots with which no interference has been made for the four seasons during 

 which the test has been conducted:

Objects. (1) To note the effect of seed inoculation on the catch and yield 

 secured. (2) To determine the best time of year to sow the seed and 

 the proper amount to sow per acre. (3) To see what type of soil is besl 

 adapted. (4) To determine whether lime and what fertilizers are 

 necessary. (5) To note what weeds are most injurious. (6) To see on 

 what soils, in what sections, and by what methods successful stands can 

 be secured in various parts of the state. (7) To study the comparative 

 hardiness and foragevalue of individual plants grown from seed from 

 different sources. 



Three cuttings were made this season from the plot seeded in 1909 and a 

 total yield of 3.45 tons per acre secured, and the plot is now in good condition. 

 On another plot seeded in August, 1910, different rates of liming and inocu-
