HATCH EXPERIMENT STATION. 



[Jan, 



The average total yield of the entire area for this year is 

 8,050 pounds. The average for the entire period during 

 which the experiment has continued (1893 to 1903 inclu- 

 sive) is 6,597 pounds. The average to date is 6,718 pounds. 

 The average yield when top-dressed with manure has been 

 7,026 pounds ; when top-dressed with wood ashes, 6,304 

 pounds ; when top-dressed with bone and potash, 6,686 

 pounds. The yields for the past year, it will be noticed, 

 are considerably above the averages for the entire period. 



Different Seed 3Iixtures compared. 

 In my last annual report^ will be found a description of 

 the variation in the seed mixtures used on different portions 

 of two plots in this field (1 and 2). In one of these seed 

 mixtures timothy is the most prominent species ; in the 

 other, meadow and tall Fescue are prominent ; and these 

 different mixtures may be spoken of respectively as the 

 timothy mixture and the Fescue mixture. The timothy 

 mixture is substantially the same as that in general use 

 among farmers, including timothy, red-top, common red 

 clover and alsike clover. The other mixture includes small 

 quantities of all of these species, and in addition Kentucky 

 blue-grass and the two Fescues named. In my last report 

 the statement is made that it is believed that the Fescues will 

 hold the ground more tenaciously than the timothy. The 

 yields last year were materially greater on the portions of 

 the plots occupied by the timothy mixture. The rates of 

 yield on the two mixtures for the past season are as fol- 

 lows : —
