 corn, potatoes, small fruits and orchard fruits, fertilizer experiments, 

 the use of burned and unburned lime, improvement of wheat by head

 use of crimson clover as a cover crop. Demonstrations were also con- 

 ducted during the year on about 8 acres of the station farm of the use 

 of dynamite for clearing the land of stumps, digging ditches, and
