THE GARDENER. 



while plants of the same latitude irx Asia can only 

 exist in the tan-pit of a hothouse. 



The degrees of heat in the old and new continents, 

 in the same latitudes, are very different. 



Heat (by means of warm water) is conveyed to the 

 tan-pit of the house I am noticing, by a pipe con- 

 ducted through the tan, within a foot of the bottom, 

 from the boiler and furnace outside ; and if necessary, 

 the air of the inner room can also be warmed by an 

 extension of the tube ; but the inner room is found to 

 be sufficiently warmed, even in severe weather, by oc- 

 casionally opening the door of communication, when 

 the heat reflected from the glass during sunshine is 

 insufficient. In that room are the Cape Heaths and 

 Camellias, Fuchsias, Calceolarias, Cacti, New Holland 

 plants, and others which do not require the stoveroom, 

 or any that may have been too much drawn up there, 

 or that have become mouldy from want of a free cir- 

 culation of air. 



There is also another shed on a still smaller scale in 

 every respect for the tropical plants, which require a 

 higher temperature, and therefore cannot be always 

 associated with the hardier ones. In this detached 

 room is a small tan-pit, extending along the front, for 

 propagating and forcing the tropical plants, and with 

 only one alley at the rear of it. In this, as well as in 

 the other stovehouse, there are vines planted in the 

 usual way, viz. about two feet and three feet distant from 

 each other, outside the front walls, the stem being in- 

 troduced to the interior through the walls and glass, 

 and trained to the rafters above. 



In order to enable him to propagate cuttings exten- 

 sively, and to keep up a numerous stock of the same 

 varieties, the nursery-man, to whom I am still allud- 

 ing, has a great many garden frames of different sizes, 

 most of which in the spring, and until the beginning of 

 June, are filled with young plants in pots, or in the
