26 THE CULTURE OF THE GRAPE. 



and all expenses, two hundred and seventy-five dollars ; or, 

 about sixteen dollars the running foot. The grapery is not 

 heated by artificial meaiis. 



" This house is built on a brick foundation, and the finish is 

 of the most complete kind ; fifty or seventy-five dollars might 

 have been saved, if desired, in the labor bestowed on the 

 wood work." 



FURNACE FOR HEATING THE GRAPERY. 



In remarks on forcing, it has been intimated that the sim- 

 ple furnace and flue are, at all times, a valuable aid in the 

 grapery. They are of easy construction, and may be made 

 of these dimensions, and after this plan. 



The furnace should be sunk in the earth so that the top of 

 it may not be over ten or twelve inches above the floor of the 

 house. It should be so placed, that the whole of the heat 

 may be given out in the grapery, the door and end being in 

 the furnace-room, so that the smoke and dust from the flues 

 may not injure the foliage of the vines. The pit for the fur- 

 nace should be about four feet wide, and three or four feet 

 deep, and of convenient length for working the fire. The 

 furnace should be two feet or two feet six inches wide, and 

 about three feet in length. The ground should be paved with 

 stone or brick for the foundation ; on this build the furnace, 

 leaving ten inches in height in the centre, and of the length 

 and width of the grate for the ash-hole. (See end view of a 

 greenhouse furnace.) Now set the grate, which will require 

 about two and a half inches of space ; build up the brick 

 work, leaving a space for the fire of about twelve or thirteen 

 inches high by ten or twelve inches wide, and two feet four 

 inches deep on the inside. The door should be of cast iron, 

 and on a cast iron frame, which should be set in the masonry 

 in building. The grate endures the heat from the anthracite 

 coal better if cast in separate pieces, half an inch thick, 

 and two and a half inches deep, with two spaces of about
