(K* FORCING VEGETABLES. 103 



As I stand pledged to offer some remarks on forcing, or 

 ratlier forwarding vegetables by artificial means, I shall 

 endeavour to confine my observations to such points as are 

 of primary importance ; and in order to convince my 

 readers of the importance of this subject, I shall first 

 endeavour to show the utility of an artificial climate suited 

 to the various species of useful plants. In England, a 

 regular succession of vegetables can be obtained from the 

 natural ground in every month of the } 7 ear, and their fruits, 

 from the Summer heat being moderate, are of longer con- 

 tinuance than with us, and yet they make gardening a 

 science, and employ the elements, as well as the ingenuity 

 of man, to the production of fruits and vegetables out of the 

 ordinary season. 



I shall not attempt to treat of the cultivation of Pine 

 Apples, Grapes, Cherries, or other fruits grown in forcing 

 houses ; nor would it be advisable with us to undertake to 

 raise Cucumbers, Melons, &c. in frames throughout the 

 severe Winters of our Northern States, but it must be 

 acknowledged, that the extreme heat of our Summers is as 

 detrimental to the cultivation of some of the most valuable 

 kinds of fruits and vegetables, as the coldness of our Win- 

 ters, and for those reasons, artificial aid is more necessary 

 here in the Winter and Spring of the year than in England. 

 The inhabitants of that country may obtain a supply of the 

 different varieties of Artichokes, Broad Beans, Borecole, 

 Broccoli, Cauliflower, Rale, Lettuce, Radishes, Rhubarb, 

 Spinach, Turnips, and Salads in general, a great part of 

 the year, from their kitchen gardens, whereas, if we were to 

 attempt to supply our markets with culinary vegetables at 

 all times, in any thing like the abundance that they have 

 them there, we must, out of the ordinary season for garden- 

 ing operations, turn our attention to the protecting and for- 

 warding as well as the forcing system. 



Before I proceed to show the method of forcing vegeta- 

 bles, it may be necessary for me to remind my readers, that 

 in providing an artificial climate, they should consider the 

 nature of the plants they intend to cultivate, and endeavour 

 to supply them with that which is best calculated to nourish.
