 different samples of grains and equipped with small microscopes, tape 

 measures, scales, germinating apparatus, etc. The laboratory is pro- 

 vided with one side case, containing 253 drawers for samples of corn 

 of ten ears each, used in instruction in corn judging and the study of 

 varieties of corn. There are a large number of tilting bins, holding 

 from 1 to 3 Inishels of corn, and a large wall case contains six upright 

 bins, reaching nearly to the ceiling of the room, each of several 

 bushels' capacit}', used for holding a supply of some of the stock grains 

 used in the farm crops work. There are six large herbariimi cases for 

 preserving specimens of different farm crops and of weeds injurious 

 to farm crops. There is also a cabinet provided with a large numl^er 

 of cases for a collection of insects injurious to farm crops. Adjoining 

 the farm crops student laboratory is a large germinating room, al)out 

 7 feet wnde and 20 feet long, with wide shelving around the walls, 

 extending from near the floor to the ceiling, giving sufficient space for 

 se^'cral himdred germinators. This room is provided with steam coils 

 with valves so arranged that any number of coils can be used and the 

 temperature of the room regulated as raav be desired. A large elec- 

 tric incubator is also provided for special germination studies. Besides

 experiments under field conditions, several acres being provided for 

 this purpose and hand tools l^eing provided for student use.
