A. Agricultural Department. 



This department exhibited a considerable variety of fod- 

 der stuffs and vegetables, grown for the purpose of studying 

 varieties, and to observe the effects of different methods 

 of fertilization on growth and development. 



1. Fertilizer Tests for Ten Years with Com. — This ex- 

 hibit illustrated the yield from one-twentieth of an acre, 

 when no fertilizer was used, when a one-sided fertilizer 

 such as phosphoric acid or phosphoric acid and potash was 

 applied, when a complete fertilizer containing nitrogen, 

 phosphoric acid and potash was employed, and when barn- 

 yard manure served as the exclusive source of plant food. 

 The entire amount of corn from each of the one-twentieth 

 acre plots was placed in barrels, thus illustrating quite 

 forcibly to the observer the noticeable differences in yield 

 resulting from the different fertilizers applied. The yields 

 were as follows : no fertilizer, 10.5 bushels of ears per 

 acre; phosphoric acid alone, 18.5 bushels per acre; phos- 

 phoric acid and potash, 41.2 bushels per acre ; nitrogen, 

 phosphoric acid and potash, 55.9 bushels per acre; and 

 barn-yard manure, 67.7 bushels per acre. The amount of 

 fertility in the barn-yard manure was considerably greater 

 than that applied in the form of the complete fertilizer, and 

 the manure plot naturally showed a somewhat larger yield. 

 The effects of plant food applied either in the form of 

 fertilizers or as barn-yard manure is strikingly shown when 

 it is observed that where no fertilizer was applied the yield
