THE VINERY. ~25 



tue expansion attending the freezing of water detained be- 

 tween tho laps by capillary attraction. As a further pre- 

 ventive, the interstices are sometimes filled with putty, and 

 occasionally with laps of lead or copper. This effects a 

 considerable saving of glass and of heat, but imposes on 

 the gardener the duty of increased attention in preventing 

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

 be well coatejl with oil-paint ; white-lead of a stone color 

 being preferred. 



In closing these preliminary remarks, it is proper to ob- 

 serve 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 management, skill in prun- 

 ing, and some knowledge of physiology, 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 cul- 

 ture required in each ; and we shall take them in the fol- 

 lowing 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. The vinery is susceptible 

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

 seems more pliable than any other forcing-house. That 

 form, however, which has been most commonly used, is the 

 plane roof with sliding sashes ; and such is the success with 

 which it has been employed, and such its convenience for 

 every purpose, that it is not probable it will soon be gene-
