JOHN BROOKS JR.'S STATEMENT. 



POTATOES. 



The half-acre on which my Davis Seedling potatoes 

 ^grew is a wet soil, with a clay sub-soil. The crop of 

 1856-7 was grass without manure. It was plowed in 

 the fall of 1857 with a double Michigan plow, about 

 nine inches deep ; harrowed and furrowed in the spring; 

 manured with seven and a half loads, spread before 

 plowing in the fall ; a handful of plaster in each hill at 

 planting, and twelve bushels ashes applied to the hill 

 on hoeing the first time ; planted May 15, in hills, with 

 six bushels Davis Seedlings ; hoed twice and harvested 

 October 12.
