48 THE CONSTRUCTION OF THE FORCING-HOUSE. 



feet high at the ridge, with no glass on the sides, on post 

 wall, can be built for $1,000 to |i,2oo, steam heating plant 

 complete, if the workmen about the place assist in the 

 construction. 



A forcing-house 50x400 ft., broken span, with the rear 

 roof 20 ft. wide and the front one 32 ft. wide, with the front 

 wall 4 ft. high and the rear one 8 ft. high, 17 ft. high at the 

 ridge, on post walls, glass 20 x 30 inches, sash-bars 2x3 

 inches, was built, and fitted with steam, for $6,000. 



The house shown in Figs. 5 and 6 (the property of Fred. 

 Busch, Minneapolis) is 60x300 ft., with a mushroom shed 

 16x300 ft. on the back. The total direct cash expense of 

 this structure was $3,300. To this has to be added the 

 work of the regular hired men in doing all the grading, the 

 setting of the pipe posts for purlines, half of all the glazing 

 work, all the work of steam fitting, and half of the paint- 

 ing ; also 4,000 ft. of old pipe which had been used in hot- 

 beds, and all the glass used in the gables and which had 

 been taken from an old house which was torn down. The 

 estimated expense of all this extra work and second-hand 

 material is $700, making the total cost of the house, shed 

 and all, $4,000. 



The range of nine houses shown at the left in Fig. 8, 

 and again in Fig. 9 (also the property of Mr. Busch), each 

 house 20x90 ft., cost, complete, as I am informed by the 

 owner, $3,600. This is an unusually low cost, being only 

 $400 per house.
