modern date in this country. We be- 

 lieve the first who successfully established 

 this practice was M. Lang, gardener to 

 the King of Bavaria, a notice of which 

 will be found in the fifth volume of the 

 " Gardeners' Magazine." Underneath 

 the pines are planted rhubarb and sea- 

 kale ; the other compartment is well 

 adapted for cucumbers and melons. The 

 compost is laid on slates supported on 

 timber, which lie across the pipes. The 

 slates are 2 feet wide ; between each is a 

 vacuity, for tying and earthing up the 

 plants. Underneath the slates is grown 

 asparagus, which answers admirably. In 

 the summer, when no top heat is wanted, 

 the pipes at e, on fig. 455, are plugged up, 

 and the hot water all passes under the 

 chamber, to supply the bottom heat for 

 the pines. The flow-pipe from the boiler 

 to e is to be covered with a slab, (see I on 

 section,) or it may be covered with sand 

 in the summer ; and if kept moist it will 

 give out a fine humidity to the plants. 

 The water is heated by a common round, 

 open-top, 35-gallon boiler: the price is 

 from sixpence to sevenpence per gallon. 



The flue is surrounded with a cavity, (see 

 o,) into which cold air is admitted through 

 an aperture above the furnace door : it 

 passes over the boiler, and enters the 

 house above the flow-pipe ; thus a cur- 

 rent of external air is passing into the 

 house continually, quite moist and warm 

 when it enters the house. So great is 

 the command of moisture, that both bot- 

 tom and top heat may be kept saturated 

 if required. So economically may such 

 a stove be erected, that a tolerable house 

 might be completed for .£30, sufficiently 

 large for an amateur." — Culture of the

boiler, are four in number, dedicated to 

 fruiting pines, and in which the larger 

 plants are placed — the smaller being 

 fruited in pits. These are all of the same 

 size— namely, 40 feet in length and 13J 

 in width within, and 9 feet high from the

 are ventilated by the front sashes open- 

 ing by sliding past each other, and by 

 wooden ventilators near the top of the 

 back wall. These houses are constructed 

 entirely of wood, with upright glass sashes
