upon the border, and under the greatest care and atten- 

 tion. This will appear clear by the following experiment : 

 Mr. Knight sowed peas in the open air, and others in 

 pots, on the first day of March. In the last week of the 

 month, those in pots were transplanted into rows in the 

 open ground. On the 29th of April, the transplanted 

 peas were fifteen, and the others four inches high ; and 

 in June the former ripened twelve days before the latter. 

 For the late crops, Knight's Marrowfat sown about 

 Midsummer day, or a sowing made a week before, and 

 another a week after this time, will produce a supply 

 from the middle of September till the end of October, 

 and sometimes much later. From a sowing on Mid- 

 summer day, I have gathered fine peas of Knight's 

 Marrow after snow in November.

 practice. It is propagated by dividing the plant, and 

 planting out the young slips upon a moist bed or border, 

 in March or April.

Solanum tuberosum, or Potatoe, is a perennial, sup- 

 posed to be a native of South America. It appears,

 Raleigh, in 1586. 



The tubers of the Potatoe, from having no peculiarity 

 of taste, and consisting chiefly of starch, approach nearer 

 to the nature of flour, or farina of grain, than any 

 vegetable root production. With the flour of Potatoes
