24 a EXPERIMENT STATION. [Jan. 



of Liming the Soil and Toxic Effect of Iron and Aluminum 

 Salts on Clover Seedlings." 



The results presented in Bulletin 'No. 158 indicate among 

 other things that molassine meal possesses about three-fourths 

 the feeding value of corn meal; that it does not increase, but 

 rather tends to decrease digestibility of coarse feeds fed in con- 

 nection with it. It, however, seems to serve as an appetizer and 

 in some cases increases palatability of coarse feeds, and is recom- 

 mended for horses, as it seems to render attacks of colic less 

 probable. 



The bulletin shows that the quality of cottonseed meal and 

 hulls seems to grow poorer from year to year. The percentage 

 of hulls shows a tendency to increase and the more abundant 

 these are the lower the feeding value. The results presented 

 indicate that cottonseed feed meal possesses only about one-half 

 the feeding value of good cottonseed meal, while it sells at about 

 three-fourths of the price of the latter. 



Cocoa shells are believed to possess about one-half the feeding 

 value of corn meal. 



Wheat or grain screenings, if finely ground, may constitute 

 a useful feed, and the better samples have approximately the 

 feeding value of wheat bran. Such feeds exhibit wide varia- 

 tions. 



Flax shives ' are not believed to be worth the attention of 

 eastern feeders. 



Mellen's food refuse will, it is believed, prove "desirable if it 

 can be purchased at about three-fourths the cost of wheat bran. 



The results presented indicate that CXX feed is a quite in- 

 ferior product. 



Professor Morse shows in Bulletin No. 161 a great increase 

 in the size of clover plants and in the percentage of nitrogen 

 in them, both on the no-nitrogen plots and^on plots supplied 

 with nitrogen in the form of sulfate of ammonia, following a 

 heavy application of lime. To a lesser degree similar differ- 

 ences are shown where other nitrogen materials are applied. 

 These differences, in the opinion of Professor Morse, are pro- 

 duced rather by the action of the lime on the properties of the 

 soil than by its action within the plant itself.
