 very cold weather and for animals which are much exposed. 



The thtw to cut corn for s'thif/e {\)\). 24. 25). — Specimens of two 

 \arieties. Kustler. a medium-sized white dent variety, and Egvi)tian 

 Sweet, a huge, late, sweet variety, were cut at five different dates, 

 from September 4 to September 24. During that period the dry mat- 

 ter in the dent \ariety increased from 11.4 to I'.'.T iK'r cent, and that 

 in the sweet from 0.1 to 18.8 per cent. 



General eonclxsions (pp. 2.5, 2()). — These exjjei'iments were per- 

 loi-iiied on a limited scale with a small number of cows, but the con- 

 clusions are strengthened by the fact that they are in line with the 

 results of previous investigations at the Station. Among the infer- 

 ences are the following: 



(1) For silage it is well to grow those kinds of dent corn wdiich are 

 slightly too large to ripen in the locality, but which will become 

 mature enough for this purpose or Avill reach the glazing stage. Far 

 northward the largest flint varieties that will reach the glazing stage 

 can be used for silage, thus ])ushing the corn belt far beyond its pres- 

 ent limit. 



(2) It was evidently more i>rofitable to pnt ears of corn into the 

 silo than to husk them and then handle the stalks as dr}" fodder. 



(8) Silage has as much available nutriment as the same crop dry- 

 cured, and its succulency giA'es it additional value for feeding with 

 dry foddei'. 



(4) Corn silage should never be fed alone, nor in too large propor- 

 tion when combined with othe'r fodder. Silage and clover hay com- 

 bined make a most excellent mixture for coarse fodder. These, with 

 bran, shorts, corn meal. etc.. in ju-opei' proportions, make the most 

 economical food foi' young cattle and for making milk and l)eef in 

 Minnesota. 



(5) For twenty or cncu fcAver cattle, it pays to preserve enough 

 silage to furnish oni'-third of the dry matter of the Avinter's feed of 

 the herd. 



((■)) Vnvw produces the most digestible feed if cut in the glazing 

 stage or when the I'ud- of (he grains are beginning to harden.

 and the lack of attention paid to the selection of a " thorough-bred " 

 seed is conunented upon. Descriptions are given of experiments in 

 " breeding " corn carried on in 1888. These are accompanied b}' pic-
