nips ;(1) and of yielding, by the acre, a crop of 
greater profit and more nutritive matter than either 
wheat or barley.(2) Nor is this its whole praise ; _ 
for, besides its value as food, it is of all vegetables 
that which, from the number, shape and size of its 
roots, forms the best preparation for subsequent 
crops.(3) Of this valuable plant, botanists count 
more than sixty varieties and twelve species, which, 
for agricultural purposes, may however, be reduced 
to three ; the red, the white, and that called by the 
French the quarantaine, or forty days potatoe.— 
The last. is the least prolific; but. may, nothwith- 
standing, deserve the preference with cultivators 
near great cities; because, besides being the first 
in the market, they may be made to give a second 
crop. The other two are supposed to affect differ- 
ent kinds of soil ; the red preferring clay ; and the 
white sand or loam. Of the former, there is a vari- 
ety, more productive than any other of either spe- 
cies, and which is known (and we think degraded) 
by the name of the hog potatoe. Of this variety, 
without any peculiar care, we have raised one hun- 
dred and eight bushels on one quarter of an acre. 
Two ways are employedto propagate the pota- 
toe; Ist, by sowing the seed ; and 2d, by planting 
the root. .By the former method, we obtain new 
varieties, or revive old ones; but asit requires three
