Preparing Land with Dynamite. 

 There has been extensive propaganda by the interested mak- 

 ers of dynamite as to its agricultural use. Trials were under- 

 taken at Highmoor Farm in 1912 with dynamite in the field 

 and in the orchard. The actual work of preparing the land 

 with dynamite was under the direction of an expert sent out by 

 one of the powder companies. 



EXPERIMENTS WITH FIELD CROPS. 



An acre and a half of land, the soil of which is fairly uni- 

 form, that was in pasture and apparently had not been in 

 crop for twenty-five or more years, was made free from 

 stone, divided into three uniform plots of a half acre eacn, 

 and treated as follows in September, 1912: One-half acre was 

 plowed and then sub-soil plowed. Another half acre, die 

 middle one, was prepared by boring holes 30 to 36 inches deep 

 a rod apart and discharging one-half pound stick of 20 per 

 cent dynamite in each hole. The third plot was plowed in the 

 usual way. The plan involved leaving the whole field to be 

 treated alike each year to see if any difference could be noted 

 in the resulting crops due to the three different methods of 

 preparation. 



The soil is the usual rather moderately heavy loam of High- 

 moor Farm which is underlain with a very difficultly penetrable 

 sub-soil. In the spring of 19 13 the whole field was plowed 

 and the proper seed bed made for the planting of potatoes. 

 The field was planted to potatoes in 1913, to corn in 1914,
