season, than under any other mode of culture which I have 

 seen ; and as the plants acquire a very large size early in the 

 summer, the tubers, of even very late varieties, arrive at a state 

 of perfect maturity early in the autumn. 



Having found my crops of Potatoes to be in the last three 

 years, during which alone I have accurately adopted the 

 mode of culture above described, much greater than they had 

 ever previously been, as well as of excellent quality, I was 

 led to ascertain the amount in weight which an acre of ground, 

 such as I have described, the soil of which was naturally poor 

 and shallow, would produce. A colony of Rabbits had, how- 

 ever, in the last year, done a good deal of damage, and 

 Pheasants had eaten many of the tubers which the Rabbits 

 had exposed to view ; but the remaining produce per acre 

 exceeded five hundred and thirty-nine bushels of eighty- 

 two pounds each, two pounds being allowed in every bushel 

 on account of a very small quantity of earth which adhered to 

 them. 



The preceding experiments were made with a large and 

 productive variety of Potatoe only ; but I am much inclined 

 to think that I have raised, and shall raise in the present year, 

 1828, nearly as large a produce per acre of a very well known 

 small early variety, the Ashleaved Kidney Potatoe. Of this 

 variety I selected in the present spring the largest tubers which 

 I could cause to be produced in the last year ; and I have 

 planted them nearly in contact with each other in the rows, 

 and with intervals, on account of the shortness of their stems, 

 of only two feet between the rows. The plants at present 

 display an unusual degree of strength and vigour of growth, 

 arising from the very large size (for that variety,) of the
