March 4, 1817. Thomas Andrew Knight, Esq. the 

 President, sent, for distribution, three varieties of Potatoes, 

 which he particularly recommended to the attention of 

 the Society : the first, a long potatoe, is for summer use ; 

 its merits declining soon after the stems become dead: 

 the second, a small round one, is good through the winter 

 and spring; and the third, a red potatoe, remains per-

 sort Mr. Knight has hitherto met with. These three 

 kinds, in succession, continue to supply his table through 

 the whole year. 



April 1, 1817. Mr. Maher, in a Letter to Sir Joseph 

 Banks, gave an account of a compost, which he has found 

 very beneficial to pines. He mixes one bushel of sugar- 

 baker's scum with three bushels of maiden earth (if a little 

 sandy, the better), from some common, or old pasture : 

 these are well blended, and frequently turned over, for 

 six months, or more, taking especial care not to let the 

 heap heat, or become mouldy. When he wishes to pot 

 his pine plants, he mixes three parts of this compound with 

 one of ordinary compost of pasture mould, leaf mould, 

 and rotten dung. 



At this meeting some French grafting wax, sent to the 

 Society by M. Dubrieul, of Rouen, was exhibited. It
