Yield of corn fodder at different stages of ripeness (pp. 41-43). — In tlie 

 above experiment li* additional shocks from eacli stage of cntting were 

 used for determining the yiehl. 



"There Avere about 3^ tons of air-dry corn fodder from the late cutting, almost 

 exactly 3 tons in the medium-mature cutting, while in the early cutting the yield 

 was a little more than 2 tons of air-dry corn fodder." 



The losses of dry matter in fiekl curing and storing in the barn are 

 given. 



Influence of ensiling and field-curing on the digestibility of for- 

 age corn, H. P. Armsby [Fennsylvania 8ta. Rpt. 1892, pp. 11-22). — 

 Tlie coefficients of digestibility for green corn fodder and the same 

 ensiled, as shown by experiments with steers and sheep, are reported. 



"The results of the experiments may be summed up as follows : 



"(1) The ensiling of maize may considerably increase the digestibility of the crude 

 fiber of the green material. 



" (2) This result is only obtained when the loss by fermentation is so large that the 

 crude fiber is attacked, and is at the cost of a decreased digestibility of every other 

 iniportaut ingredient. 



" (3) The albuminoids are especially affected by ensiling, a considerable proportion 

 of them being converted into less valuable forms and the (Ugestibility of the remain- 

 der being reduced sometimes nearly or ([uite to zero. 



"(4) Such silage may be considerably more digestible than poorly cured fodder, 

 except as to the albuminoids. 



"(5) Field-curing seems in every case to decrease the digestibility of the fresh 

 substance. 



"(6) When the processes are successfully conducted and the losses small, ensilage 

 and field-curing both decrease the digestibility of the fresh materia) somewhat, and 

 to about the same extent." 



Results obtained elsewhere in this country and abroad are cited. 



Relative feeding value of turnips grown with and without 

 nitrate of soda, A. S. Logan ( Trans. Highland and Agl. Soc. Scotland, 

 1891, pp. 332-33^). — In 'J years, 1892 and 1893, turnips were grown on 

 2 plats manured alike, except that 1 plat received nitrate of soda as a 

 top-dressing while the other received none. In 1892 150 lbs. of nitrate 

 of soda was applied July 21, and in 1893 the same amount was applied 

 July 13 and again August 4. The yield of turnips per acre was larger 

 in both years on the nitrated plat — about 8,000 lbs. more in 1892 and 

 2,300 lbs. in 1893. The composition of the turnips was as follows:
