3GG THE HOT-HOUSE. [April. 



up and down by means of pulleys. Seventy or seventy -two degrees 

 of Fahrenheit will be a good medium For sun-heat; but always 

 when it rises above that give abundance of air, and in the early 

 part of the mouth this is done with more safety by sliding open a 

 sufficient number of the roof-lights. 



Succession Pines. 



The succession pines, especially those intended for fruiting next 

 season, should be shifted as early in this month as possible, if not 

 done in March. For the method of doing it, and the manner of 

 treating them after, see page 311. 



The crowns and suckers of last season should now also be shifted 

 into larger pots, and managed in like manner. 



Treatment of the other various Stove Plants. 



The general treatment directed for the pines may be given in 

 common to most other stove plants. With respect to shifting or 

 adding fresh earth to the pots, that should now be done in the same 

 manner as directed for the green -house plants; after which, if 

 there be room in the bark-bed, let the pots be immediately plunged 

 to their rims therein; and by the assistance of the kindly heat the 

 plants will root freely in the new earth, which will give them 

 strength, promote their health, revive their colour, and prepare 

 them the better for a removal into the open air towards the end of 

 next month. 



The woody kinds will now require frequent and gentle water- 

 ings, the herbaceous occasionally; but the succulent sorts should 

 get only a little now and then, as the earth in the pots seems to 

 stand in need of it. 



When any of the stove plants have contracted much dust or 

 other foulness, such must be cleaned oft' immediately; all decayed 

 leaves should constantly be picked away, and the utmost cleanness 

 preserved in all the house. 



Where insects appear on the pines, or on any of the other plants, 

 immediate attention ought to be paid to the destruction of them; 

 for, in a short time, if neglected, they would overrun the house, 

 and ruin many of the plants. For the methods of extirpating them, 

 see article Hot-house for February, page 169, &c. 



The paying of due attention to all the plants, giving them suita- 

 ble care and culture, preserving them in good health, and keeping 

 the house constantly clean, and the plants free from decayed leaves 

 and filth, is the surest method of not being much troubled with 

 insects. 



Propagating various Stove Exotics. 



You may now propagate by cuttings, layers, suckers, or seeds, 

 the various' plants of this department. Plant the cuttings in pots, 

 plunge them in the bark-bed, and the kinds that grow by that
