purpose ; the roots of the plants will grow freely in 

 it, and their extremities will have a clear white and 

 healthy appearance. 



Salt. — In some districts near the sea, as in Brazil, 

 and on soils not only strongly impregnated with salt, 

 but actually flooded occasionally with sea water, pine 

 apples grow to an enormous size. Hence, it is reason- 

 able to infer that salt is assistant to the health and 

 growth of this fruit, and we hope cultivators will try 

 some experiments to confirm or refute this inference. 



PITS AND STOVES. 



When pine apples are required all the year round, 

 it is especially desirable that there should be two 

 structures devoted to their cultivation ; because, to 

 obtain them in perfection, they must have a period 

 of rest, and this can only be given to them in a tem- 

 perature much below that in which their fruit is 

 ripened. Moreover, Mr. Glendinning is right in 

 observing that the pine plant in its younger stage, if 

 supplied with the same degree of heat and moisture 

 requisite to mature the fruit, has its foliage drawn, 

 and the whole plant so constitutionally weakened, 

 that nothing but disappointment would follow, the 

 fruit of such plants being invariably puny. 



In the winter months it is also desirable to keep the 

 young plants comparatively at rest, and this requires a
