growth are also computed. Using the ordinarily accepted coefficients 

 of digestibility, the author computed the digestible matter per ton and 

 per acre as, follows: 



Digestible matter in corn fodder at different stages of growth. 



Among the conclusions reached were the following: "Cutting the 

 corn before it reaches the glazing condition — a practice quite common 

 a few years ago — is not to be advised, since in the later stages of the 

 plant's growth there is a large gain in food constituents. . . . The min- 

 eral constituents (ash) are taken by the plant from the soil more par- 

 ticularly during its early stages of growth." As the plant matures the 

 amount of nonalbuiuinoid nitrogen decreases while the albuminoid 

 nitrogen increases. The percentage of carbohydrates also increases as 

 the plant approaches maturity. 



Analyses of fodders and feeding stuffs (Maine Sta. Epi. 1896, 

 pp. 28, 29). — Analyses are reported of the following feeding stuffs: 

 Sunflower (heads and whole plant); English horse beans; silage from 

 mature corn, sunflower heads, and horse beans; corn planted at 0, 9, 

 and 12 inches; King gluten meal; potato pomace, and black grass 

 (Jiincus gerardi). The composition of a number of these is given in 

 the following table:

Sunflowers and English horse beans as silage crops, J. M. 

 Bartlett (Maine Sta. Iipt. 1896, pp.32-34). — For several seasons sun- 

 flowers and horse beans have been grown at the station for silage. The 

 crops were harvested in the early part of September, run through a 

 silage cutter, and mixed with corn in the silo in the following propor- 

 tion : One-fourth acre of sunflowers, one-half acre of horse beans, and 

 one acre of corn. In half the silage the whole sunflower plant was cut 

 up and in half the heads only. Both mixtures were well preserved, 

 and when opened in January were greedily eaten by cows. Although
