plants that are swelling their fruit will make little 

 progress, except the bottom heat be about 75 degs.

In a more northern latitude, and consequently 

 diminished duration of light, shghtly lower tempera- 

 tures ought to be employed than in those we have 

 mentioned, and in accordance with this we find that 

 Mr. A. Smith, gardener to Col. Paterson, of Cun- 

 noquhie, N.B., states that about February the tem- 

 perature is raised by him to 70 degs. during night, 

 and about 65 degs. in the morning. In May, or 

 when the flowering is over, the steam is frequently 

 admitted to the atmosphere of the pit through the 

 whole night. This seems to destroy insects, and to 

 keep the foliage of the plant in a state of fresh and 

 healthy verdure. The temperature is now about 75 

 or 80 degs., and steam is applied when artificial 

 heat is necessary to maintain that degree of heat, 

 which, in very warm weather, is only about once or 

 twice a week. {CaL Hort, Mem. iv. 573.) 



Shading — Necessary as it is to expose the pine 

 apple to a duly regulated amount of heat, and a free 

 exposure to light, yet they both may be admitted in 

 excess. Night naturally brings a refreshing period 

 of rest, but it is also beneficial to relieve those 

 plants from the effulgence of the mid- day sun which 

 are not fully rooted, and more slightly during their 

 blooming, for there is not a plant when in bios-
