The results of earlier iuvestigations ou the composition and digesti- 

 bility of corn fodder are summarized and illustrated by means of diagrams. 

 Previous analyses of pasture grass and of sorghum are also cited. 



The composition and digestibility found for the dried pasture grass 

 in 1889 varied considerably from that found in 1888. "The differences 

 in the digestibility of the different samj)les of i)asture grass are as great 

 as those between ])asture grass and any of the soiling crops." 



Yield and composition of pasture grass (pp. 97-101). — The same piece 

 of land was used for determining the yield as in 1888 — a plat 7 rods long 

 and 1 rod wide. The grass was cut with a lawn mower whenever it 

 became long enough, or about once in 6 days. "There was ijroduced 

 for the season ending October 15, 5,719.78 pounds of fresh grass per 

 acre and 1,()1L'.91 pounds of dry material." The composition of the grass 

 is given, and fiom this the amount of digestible nutrients produced per 

 acre is calculated by means of the coefficients of digestibility given 

 above. The rainfall during the season was very favorable to the growth 

 of grass. 



The yield of digestible food ingredients per acre as compared with 

 that in 1888 is given as follows :

"The yield of the pasture was much greater this year than last, 

 owing largely, undoubtedly, to the more favorable season and the less 

 frequent cutting of the grass. The yield of rye was less and that of clover 

 considerably less than in 1888." 



As in the preceding year, the rate of growth of the grass per day at 

 different times in the season is calculated, and this is illustrated by a 

 diagram.
