Figure 43 gives the ground plan of a combined hot-house 

 and greenhouse, each 20 feet wide and 50 feet long, show- 

 ing the disposition of the boiler and pipes. If this

plan were shown in full on 

 be quite too small, there- 

 fore a portion of the length 

 is left out of each compart- 

 ment, as shown by the ir- 

 regular lines; everything is 

 given in proper proportion 

 except the length, and that 

 is stated in figures. The 

 number of pipes indicated, 

 (10), is sufficient to give a 

 temperature of from 60° to 

 70° at night for the hot- 

 house, and the number given in the greenhouse, (6), is 

 such as will keep that compartment at from 40° to 50° 

 in the coldest weather. A sectional view at the end where 



the boiler pit is placed is 

 given in fig. 44, and an- 

 other sectional view at 

 the partition between the 

 greenhouse and hot-house 

 is shown in fig. 45. The 

 cost of such a structure 

 complete for the reception 

 of plants, would vary ac- 

 cording to location, and 

 the style of finish; in the vicinity of New York at pres- 

 ent prices, such a combined hot-house and greenhouse, 

 20x100, erected in a substantial manner, would cost 

 about $3,000.
