they, as to prevent the escape of the fertahzing gasses, 

 which must otherwise evaporate unappropriated by the 

 trees. 



So far as I have observed, those plum trees have been 

 exempted from these fungi which are located in good soil 

 not subject to drought or deficient in moisture. Trees 

 standing beside a heavy wall prosper better (other things 

 being equal,) than those which stand in the open field, on 

 account of the protection which the wall proves to the 

 roots. 



Entertaining these views, I would recommend to fruit- 

 growers the following mode of cultivation, as a prevention : 



Let the plum trees be set in a soil rather loamy and 

 moist, and they may be set within 8 or 10 feet of each 

 other. The soil should be in good condition as to richness, 

 and being made smooth and level, should be covered over 

 with a good coating of straw, old hay or leaves. This 

 covering is to lie year after year, and decompose as the 

 leaves do in the forest, having addition made to it from 

 year to year, as may be necessary. 



Such a course of management will make the soil ap- 

 proximate to uniformity as to temperature, richness and 

 moisture, and, I believe, insure success in cultivating the 

 plum ; and not only is it suitable to the plum, but will en- 

 hance success in the cultivation of other kinds. 



Very respectfully your obedient servant,

Strawberries. 

 No task has been more difficult to the amateur fruit cul- 

 tivator, than the selection of a list of strawberries suitable 

 for a small garden. So many varieties have been produced 

 from seed, and such a large number of them have been
