THE VILLA GARDENER. 



apparatus may either be placed on the floor of the house to be warmed, or 

 raised by bearers, or suspended by wire or cord; the two latter methods 

 making the fire to bui"n more freely. 



527. A mode of heating employed at Stratlifieldsaye, is shown in fig. 352. 

 The apparatus consists of a stove (originally Dr. Arnott's) and two copper 

 cylinders. The stove con- 

 tains two copper boilers 1 ft, 352 



deep, and 3 in. wide, which 

 form the fire-box of the 

 stove, out of which the 

 boiling-water flows by the 

 top pipe into the cylinder, 

 and returns by the lower 

 pipe into the bottom of the 

 boiler. The cylinders have — 



each thirty tubes, one inch 

 in diameter, extending 

 through their whole length, 

 and among which the water 

 flows ; so that the stove and 

 the two cylinders all radiate 

 heat equal to their surfaces, 

 and warm the air that 

 passes between them. The 



stove is 18 in. square, and 3 ft. 9 in. high, including the ornamental cap at 

 the top, which is four inches deep. The cylinders are 18 in. in diameter, 

 and the same height as the stove. The apparatus consumes a bushel of coke 

 every day, half being given in the morning, and half at night. The water is 

 given through a covered valve near the top of each cylinder, as shown in the 

 figure. There is a small pipe for evaporation at the back of each cylinder. 

 The ornamental caps are moveable, and conceal the tubes of the cylinder, and 

 the feed-hole of the stove. The smoke escapes by a tube at the back of the 

 stove, communicating with a flue built in the wall. The apparatus has a 

 very neat appearance, and two of them are found suflicient to heat a con- 

 servatory 67 ft. long, 27 ft. wide, and 21 ft. high, so as to preserve the plants 

 from injury by cold or damp. For other modes of heating, sed Loudon's 

 Horticulturist, p. 194 to p. 218, where the subject will be found fully 

 discussed. 



528. Plant cabinet heated by hot water. — Fig. 353. is a plan, andi Jig. 354. a 

 cross section, of a plant cabinet, in which the stage is placed along the sides 

 and against one end. The stove for heating it is placed at a, from which hot 

 •water pipes proceed to the right and left under the side stages ; the two 

 shelves, b b and c c being for the purpose of concealing these pipes. The 

 stove is concealed by the portion of the stage d, which is ou casters, and 

 draws out with the pots on it, to admit the operator to the stove. The hot- 

 water pipes are seen in the section {fig. 334.) at e e. The smoke from the 

 stove may be conducted away in a tube under one of the stages, and carried 

 up the side of the house, as indicated at /. The water of the roof may be 

 collected and conducted to a cistern under the stage by the pipe g, placed in 

 the opposite angle to the smoke tube. Props for climbers may be placed as
