constructed green-house, and in which, excepting 

 in the above described house, the plants would en- 

 joy the fullest share of sun and light. 



In either of these houses, and also in that spoken 

 of below, a sufficient number of the upright and 

 sloping sashes should be made moveable, for the ad- 

 mission and regular circulation of air in the better 

 seasons of the year ; and ventilators (see Section I. 

 of the Forcing Garden) should be placed at regular 

 distances all round, for the purpose of airing and 

 ventilating them in the winter months, or at times 

 when it may not be safe to open the lights. 



Such a house as either of these, would form a very 

 complete receptacle for a handsome and pretty ex- 

 tensive collection. But for a full collection, and 

 particularly in order to answer the purposes of pro- 

 pagation, a smaller house, that is, one lower and naiv 

 rower, of whatever length, would be necessary, be- 

 sides the above green-house. Such should be con- 

 trived., so as to have the plants quite near to the 

 glass ; being placed on flat, or flatish stages, an- 

 swerable to their respective sizes ; the flue running 

 under the stage, and having a narrow, sunk alley 

 behind, just wide enough to allow a person to sort 

 and water the plants with freedom. 



A house of this kind should have no upright glasses 

 in front, as the foremost stages should be nearly 

 level with the wall-plate, or sole of the rafters. The 

 ends should be glazed, however, in order to admit 

 the morning and afternoon sun ; but the back, or 

 north side may be close. It should not exceed nine 

 or ten feet in width ; nor should the back-wall be
