Nov.] THE HOTHOUSE. 575 



keeeping the air of the stove or hot-house in a proper and regular 

 temperature of heat, in duly proportioning the quantity of water to 

 the different natures and necessities of the various kinds of plants, 

 in judiciously admitting a sufficiency of air at suitable opportuni- 

 ties, and in keeping the bark-pits in a proper state of fermentation; 

 all which must be duly attended to, or the desired success cannot 

 be expected. 



Pick oft* constantly all the decayed leaves from the plants, and 

 throw them out of the house; clean their leaves and stems from 

 tilth, which many kinds are subject to contract; wash oft' and 

 destroy all insects which infest any of them, frequently stir the 

 surface earth in the pots to keep it from contracting moss, &.c, and 

 keep all the house clean, sweet, and in neat order. 



Care of Young Succession Pines and other Plants. 



The young pines or other plants in succession houses must have 

 the same care as above; and those in bark-beds, under garden 

 frames, are to be diligently attended to; the outside lining must be 

 kept to the full height of the frame all around, and in a regular and 

 constant state of warmth; the glasses must be carefully and suffi- 

 ciently covered every night, and by day in a very severe frost, but 

 the plants should have as much light as possible, and air whenever 

 it can be given with safety: decayed leaves must constantly be 

 picked oft" and taken out of the frame, but watering will seldom be 

 necessary at this season, as the steam arising from the bed will 

 occasion a moist atmosphere about the plants. Observe that the 

 more succulent kinds will not keep as well in such a place as in a 

 dry stove, or on shelves in the hot-house. 



The garden pits erected with brick and furnished with flues, in 

 which you have tender exotic plants, must also have, a lining of 

 hot dung placed around them to their full height, in order to prevent 

 the frost from penetrating in through the wall; moderate fires must 

 be made in the flues every evening, and in severe weather to keep 

 up the internal heat when that of the pit is found not to be suffi- 

 ciently strong: the glasses must be well covered with mats, &c. 

 every night, and even by day when the weather is cloudy and the 

 frost very severe.
