PRACTICAL GARDENING 



amount of sun for a long period of the day. 

 After the excavation is complete, drive a two 

 by four strip in each corner of the pit and 

 place the boards so that the four supports are 

 on the inside of the frame. The inside meas- 

 urements should be three by six feet. Have 

 one end fifteen inches above the surface and the 

 opposite end eight inches above the surface. 

 The sash should slant toward the south. 

 Place one inch boards from the floor of the pit 

 to the top of the supports and nail. Place a 

 thick lining of tar paper or building paper on 

 the outside from the base up and nail on an- 

 other covering of one inch boards. This may 

 all be done before the sides are put in position 

 and finally joined to the two by four strips by 

 nailing the sides above the surface soil. By 

 placing boards up from the bottom of the pit 

 there is less danger of water getting in, heat 

 getting out, and the earthworm is kept out 

 of the manure. The sash bars should be fast- 

 ened so that there are no openings to allow 

 any draft and so that the sash may fit snugly.
