Jan.] THE HOTHOUSE. j^ 



ing a bark-pit; it is furnished with Hues as the other, and conse- 

 quently produces a more dry heat; being intended principally for 

 the culture of some very succulent tender exotics of parched soils 

 that require to be kept always dry. Persons who have full collec- 

 tions of exotics prefer this kind of stove, in order to deposit the 

 most succulent kinds therein, separate from plants which perspire 

 more freely, lest the damp occasioned by such perspiration, and die 

 more frequent watering of these kinds, should be imbibed by the 

 succulents and injure them. 



However, most of the tender succulent kinds are cultivated and 

 preserved in the bark stove, placed on shelves, and in dry situations, 

 with very good success. 



In this kind of stove are erected movable shelves or stands 

 above one another, theatre ways, on which to place the pots of the 

 various kinds of plants intended to be kept therein. 



Stoves have been constructed on various other plans, according to 

 the fancy of the owners or their desire to try experiments; some 

 circular, some crescent form, and others ranging north and south, 

 with double roofs and upright sashes, all of glass work; but these 

 not being found to answer as well as those described, it is unneces- 

 sary to take further notice of them. 



For the various kinds of forcing-frames, and their respective 

 uses, see page 35. 



Pines. 



At this season the pinery hot-house requires good attendance, 

 for some of the pines will now, towards the end of the month 

 begin to show fruit; and your assistance is at no time more neces- 

 sary than when the fruit first appears, especially in one particular, 

 the supporting a proper bottom heat; for if the heat of the bark-bed 

 is not kept up at that time, the young fruit will receive a check 

 more than may be imagined; as, notwithstanding the air of the 

 house can be sufficiently warmed by the flues, yet these plants also 

 require always a moderately brisk growing heat to their roots, but 

 especially when the fruit is young; and without that assistance, 

 they will not advance freely in the first growth, and being checked 

 therein, will be much inferior in size to what they otherwise would 

 have been. 



Examine therefore carefully at this time the heat of the bark-bed 

 in which the pots of pines are plunged; and if you find it very faint, 

 take up all the pots, and let the bark be forked up to the bottom. 

 But before you proceed to this, if the heat is found much decayed, 

 or the bark considerably wasted, or become very small or earthy, 

 it will be advisable to add at the same time some new tan, first 

 removing away some of the wasted bark at top and sides, and then 

 fill up with new bark, working the old and new well together. 

 When that is done, let the pots be replunged again to their rims, in 

 a regular manner. This will enliven the heat greatly; and, il done 

 in proper time, the young fruit will grow freely. 



Let the fires be made very regularly every evening and morning,
