160 Further Experiments on the Cultivation of Potatoes. 



not vegetate, or at least failed in reaching the surface. This was 

 also found to be the case by Hasler Hollist, Esq. in 1835, 

 when he adopted the mode of deep planting. The results of his 

 experiments are detailed in the following note. 



" I have this year renewed my experiments on the Potatoes 

 you sent me in 1833 from Mr. Knight's Collection. 



I planted in the latter end of March and at intervals during the 

 whole month of April, but I am satisfied I was, contrary to the 

 received opinion, too early in some instances, particularly with 

 Mr. Knight's No. 2. 



I also planted at various depths, 9 inches, 7 inches, and from 5 

 to 6. In nearly every instance the shallow planting has succeeded, 

 but, in none the deepest, and in the latter case many of the sets 

 have not vegetated at all, many more have not reached the surface. 



A few single eyes of the Downton Yam, literally parings, have 

 yielded very nearly as much as the full sized sets. I think I could 

 say quite as much if the tubers from which they were cut were 

 added to their actual produce. 



Some of these statements appear so singular that I feel a hesita- 

 tion in mentioning them, but whether from the unfavourable 

 season, mismanagement, or what other cause I know not, certain 

 it is that these are my results. P.S. The soil is a loamy sand and 

 friable."
