THE PRACTICAL GARDENER. 



chieliy rest upon the wall-plate, which will be supported upon 

 blocks or piles driven into the ground at equal distances, say 

 one under every other rafter, and the space between the sur- 

 face of the ground, and such wall-plate to be boarded closely 

 with well-seasoned inch deal ; which deals should be fixed to 

 the piles, by means of screws so constructed as to be readily 

 taken out, to allow the whole to be taken to pieces when not 

 in use. The height of this boarding may be from one to two 

 feet, which will elevate the sashes so as to be opposite the best 

 part of the wall, as well as to admit of their being occasionally 

 taken down to admit air. Should the sashes not be of sufH- 

 cient length to reach from this plate to the top of the wall, a 

 part of the top of the rafters may be covered with seasoned 

 boarding, similar to the front ; but, in the case of this upj">eir 

 boarding, it will be necessary to place the boards in an imbri- 

 cated manner, to preclude the rain from getting in. The 

 sashes need not be more than three or four feet distant from 

 the wall at bottom, as all that is necessary to be done to the 

 trees can be done by a careful person inside, or from the out- 

 side in fine weather. The materials with which such a frame 

 as this is composed should be got up in a neat and portable 

 manner. The angles at the ends need not be glass, they 

 should be boarded up, and at one end a small door for the 

 admission of air, as well as for examining the trees, state of 

 temperature, &c. Several of such frames as this, or where 

 better can be" devised, will be extremely useful in every garden, 

 and the sashes may, when not in use for such purposes, be 

 employed in ripening melons, cucumbers, &c. : and in autumn 

 such frames will be of much use in accelerating the ripening of 

 late peaches, grapes, &c., upon the walls, and for preserving 

 grapes, that may have ripened, for a great length of time. The 

 many usefid purposes for which portable structures or glass- 

 cases may be used are not yet sufiiciently appreciated, we ex- 

 pect to see the time when they will be found in every garden. 



Tn glass-cases, similar to these, cherries have been success- 

 fully forced by Mr. Torbron, one of the best practical forcing- 

 gardeners of the present day. The temperature and general 

 management of the trees in them will be exactly such as is 

 already laid down, only, if it be necessary to intredncc the
