 cember. 



In cultivating plants in pots under vines, two or 

 three points deserve consideration. In the first 

 place, the pots should be at all times placed very 

 thinly ; any attempt at crowding them will assuredly 

 defeat the end in view. Those tribes also should be 

 encouraged, chiefly, which require very little water in 

 October and November. The Cape Bulbs, the Achi- 

 menes, the Cacti, &c. are somewhat eligible for this 

 purpose. Particular attention should be paid to an 

 almost constant ventilation, as before urged. 



STOVE CULTURE 



The vinery is very variously constructed, both as re- 

 gards form and material. It is built round, square, 

 and parallelogram, with wood or iron for the rafters, 

 and with flues, steam, hot water, and warmed air, as 

 the sources of artificial heat. It will enable us to be 

 more explicit if we consider each part of the struc- 

 ture separately. 



But before proceeding to discuss the merits or de- 

 merits of the various structures, we would offer a few 

 remarks on the vast importance of the greatest pos- 

 sible amount of light. The great improvement that 

 has taken place in the manufacture of glass, together
