true that these variations of season are not applicable 

 when pines are several seasons before they fruit ; but 

 then very fine pines are always produced on young 

 plants, for the whole of whose growth two seasons — 

 the cool and the hot one — are sufficient. 



Mr. Hamilton, gardener to F. A. PhiHps, Esq., of 

 Thornfield, near Stockport, and one of the best of 

 modern pine cultivators, is equally decisive in his 

 opinions as to the variations of the temperatures, 

 during the different periods of the plant's growth. 

 He says that the heat required for succession plants 

 ought to vary according to the season. In the winter, 

 when they are not growing much, 55 to 60 degs. will 

 be sufficient ; but from March to November, 70 to 

 80 degs. during the day, and 65 to 70 degs. at night. 

 {Hamilton on Pine Apple, 67.) 



In the fruiting stove he recommends the maximum 

 heat of the house in November, December, and Ja- 

 nuary, by artificial means, not to exceed 60 degs., the 

 minimum 55 degs. In spring and autumn, if fruit 

 are to be swelled, maximum by sunshine 80, minimum 

 68, medium by artificial heat 70 degs. In the sum- 

 mer, the maximum, under the effect of strong sun- 

 shine, may rise to 90 degrees, and may be allowed to 

 drop as low as 70 degrees in the morning. In very 

 bright, sunny weather, Mr. Hamilton says, the plants 

 in fruit had better be shaded, than have admitted to 

 them too much air at any time of the day. From
