Analysis of Commercial Fertilizers. 
About 1,000 samples of commercial fertilizers have been collected 
from every portion of the State and nave been analyzed. Most

Feeding Experiments.— Poultry and Swine. 
Feeding trials have been made with various coarse foods which 
have been and are often recommended for swine. 
Feeding experiments made with zoo0d quality of corn silage 
showed that the silage was fed at a loss except when forming only 
a small proportion of the ration. (Ninth Report, pp. 141-151. Bul- 
letins 22 and 28.) 
_Prickley comfrey could not be profitably fed to pigs. (Ninth 
Report, pp. 151-152. Bulletins 22 and 28.) 
Clover forage was not fed profitably except when forming only 
a small per cent of the total food. This refers to pigs fed in ¢ 
pen and not at pasture. When clover forage constituted only 
about twenty per cent of the water-free food in a ration the large; 
part of which was corn meal, it was profitably fed. (Ninth 
Report, pp. 154-156. Bulletin 28.) 
' Short feeding trials with sorghum and mangolds gave encour. 
aging results, and more extended trials are now being made. 
(Ninth Report, pp. 156-158. Bulletin 28.) 
The feeding of salt to pigs in small quantities has given good 
resnits when added to the rations usualiy fed, but with mangoids 
was of disadvantage. (Tenth Report, p. 205. Bulletins 22 and 28.) 
Analyses of pig manure from lots fed different rations have 
been made, indicating the value of solid inanure from every 1,000
