THE GREEN-HOUSE.

off every morning when the sun is quite receded from 

 them, and putting them on again early in the follow- 

 ing morning. By this means they will in the course 

 of a few weeks become so hardened, as to be able to 

 bear the full power of the sun without the glass ; 

 when the shading and glasses may be laid entirely 

 aside. If any of them should droop their heads when 

 this operation is first performed, it is proper to refrain 

 from moving the glasses until they have gained more 

 strength. The shading is also to be decreased by 

 degrees, but not so much as to be entirely done away 

 while the glasses are in use. 



The operation of planting cuttings, and their routine 

 culture in this way, may go on from the beginning 

 of February to the beginning of July ; after which 

 only the most hardy and easily-rooted sorts should be 

 attempted, on account of the little chance of getting 

 them potted and hardened before winter. Geraniums, 

 however, may be propagated by cuttings till Septem- 

 ber, by placing only one cutting in a small pot, and 

 then plunging the pot in heat: the cutting in this 

 way becomes a neat little plant in the course of a 

 month, and will stand the winter in the same pot. 



The most difficult green-house plants to strike 

 are heaths, the particular mode of operating with 

 which we have already given. These and almost 

 all the woody shrub-like plants, as the Protedcece, 

 MyrtedcecB, Diosmdcece, &c., propagate most readily 

 during the months of May and June, when the wood 

 is in a growing state. Any one may convince him-
