IN AN IMPROVED PIT. 49 



The dimensions for the pit and cavity having 

 been correctly determined, the earth removed 

 and proper drainage secured, where the soil is 

 such as to require it, commence the brickwork 

 for the pit within which the plants are to grow, 

 by laying a foundation of one course, back and 

 front, fourteen inches wide, but single brick, or 

 four-inch work solid at each end from the bottom 

 to the top, and nine-inch foundation, Let the 

 south or front side be the first to be carried up 

 by laying five courses in pigeon-hole fashion, 

 commencing two-and-a-half inches from the out- 

 side of the ground-course, and laying upon them 

 six more courses solid of single brick. This will 

 make twelve courses ; and when these are com- 

 pleted, commence a brick-on-edge course inside 

 them, resting two-and-a-half inches from the 

 inner edge of the broad foundation brickwork, 

 admitting, which the space will then do, of a 

 chamber between them of two- and-a-half inches. 

 Eight courses on edge solid, with the mortar 

 used in setting, will bring the inner brickwork
