20 TRACTS ON VARIOUS SUBJECTS, &c. 



The following is an abstract from the preceding table, and is a 

 comparative view of the effects of the several classes of seed, 

 shewing the total produce in pounds. 



Potoids. 



Class 1. Seed the size of walnuts planted whole, yielded 553j 



2. Large seed cut in pieces - - - 588^ 



3. Eyes of middle sized potatoes - - 487^ 



4. Small potatoes planted whole - - 615^ 



I total pounds - 2245 



These results will be pleasing to the planters, since they have 

 clearly ascertained that small potatoes planted whole, which 

 would not fetch so good a price in the market as the largest sort, 

 are the best for seed. 



The following is a comparative view of the effects of different 



depths of planting, shewing the total produce in pounds. 



Pounds. 



1st. Six inches deep, yielded - - 637 



2d. Three ditto, ditto _ _ _ 549 



3d. Nine ditto, ditto - _ _ _ 547^ 



4th. Twelve ditto, ditto _ _ _ 5111 



Total pounds - 2245 



By these results, it is proved, that planting at the depth of six 

 inches on stiffish land is the most productive: but if the soil be 

 of a lighter and freer sort, it is probable nine inches, or more, 

 would yield best, because the moisture necessary for vegetation 

 lays deeper in that sort than \n a mo^e retentive soil.
