 In your volume for 1846, p. 51, you gave a descrip-

 might as well circulate, and accordingly I bad a stout 

 copper boiler placed on the stove over the fire. This

 in a soil the moisture of which is sufficient for the 

 plant till it attains a tolerable size. Mechanical

 of houses devoted to plant growing or forcing. Partial 

 success may and does attend such a course, but where
