any appreciable amount, with the crop of corn, by 

 turning down, as usual, a stiff sod, and in planting 

 the peach trees at 16x18 feet in the rows we will 

 have one hundred and fifty to the acre. Using that 

 many hills of corn, the corn being planted 3x4 at, 

 say eighty bushels to the acre, the one. hundred and 

 fifty hills occupied by the trees would reduce the 

 product of the acre only about three and one-half 

 bushels. The second year we put in corn, potatoes 

 and other crops, requiring culture, also manuring 

 in the hill to make the corn crop, and this second 

 year's crop may not exceed over two-thirds that 

 of the first year; the third year to be again plant- 

 ed with corn, or such crops as require cultivation, 

 and after the third year all cropping to be sus- 

 pended, but the field or orchard thereafter to be 

 cultivated by plowing and harrowing it at least 

 once a year, and oftener in years of overbearing, 

 as hereinafter pointed out.
