342 FORCING GARDEN. 



ing the stagnation of air. The framework of hot-houses 

 should be well coated with oil-paint ; white-lead of a 

 stone color being preferred. 



In closing these preliminary remarks, it is proper to 

 observe that although the construction of a forcing- 

 house is always a matter of considerable importance, it 

 is not the only nor even the most important condition 

 necessary to insure success. Much care in manage- 

 ment, skill in pruning, and some knowledge of physio- 

 logy, must be possessed and applied, in order to obtain 

 abundant and regular crops of fine fruit. 



The more minute details respecting the structure of 

 glazed houses, we shall notice along with the peculiar 

 culture required in each ; and we shall take them in 

 the following order : . The Vinery or Grape-house, the 

 Peach-house, the Cherry-house, the Fig-house, the 

 Pinery, the Orangery, and the Melonry. The green- 

 house and other botanical structures will come more 

 appropriately under review in treating of the Flower 

 Garden. 



The Vinery. Structure.-r-The vinery is susceptible 

 of a great variety of form ; and, indeed, in this respect, 

 seems more pliable than any other forcing-house. Th^t 

 form, however, w^hich has been most commonly used, is 

 the plane roof with sliding sashes ; and such is the suc- 

 cess "with which it has been employed, and such its coa- 

 venience for every purpose, that it is not probable it 

 will soon be generally supplanted. The section of the 

 peach-house at page 350 will convey an idea of the 

 usual 'iconfiguration of the vinery. On the following 

 page, Fig. 36 represents a section and a, ground-plan of 

 a curvilinear vinery (having a mushroom-house behind), 

 heated by hot water.
