and the ones which adhered to the potato. Should I try the 

 experiment again, I should take all the plants from the potato 

 and replant it, as it appeared as fresh and sound as the day it 

 was first put into the ground.

My second experiment was reported to the same Trustees. 



Account of four crops of potatoes raised in one season : — 



April 10th, 1821. Planted half bushel of late potatoes, 

 part kidney and part round ones, cut into sets in a hot bed. 



May 7th. Transplanted first set of vines, as I should cab- 

 bages, and replanted the sets. 



May 21st. Transplanted the second set of vines, and re- 

 planted the sets. 



June 5th. Transplanted the third set of vines, and re- 

 planted the sets, and hoed the first and second sets of 

 plants. 



June 30th. Transplanted the fourth set of vines. 



July 1st. Commenced digging full grown potatoes from the 

 first set of vines, since which, my family (a large one,) has 

 been fully supplied, and I have lately commenced digging the 

 fourth set of vines. 



The potatoes exhibited were taken from the third and fourth 

 set of vines, and there are very few small ones.

Salem, Oct. 1821. 



I could have extended the experiment much farther, and 

 have no doubt I could have raised six different crops the same 

 season, as the sets were still in fine order, when I left off the 

 experiment. I once tried raising potatoes from the sprouts left 

 in the cellar after the potatoes were removed in the spring ; 

 they were planted in a good soil in a single row, they vegetated 

 very readily, but were very feeble the first part of the season, 

 for want of nourishment from the parent set ; the season prov- 

 ing favorable in the autumn, I dug a tolerable crop of good 

 sized potatoes. 



The present season I took two potatoes, weighing together.
