turf and surface humus where directed — tliis soil not to be 

 used for building. 



(2) Lay a 6-inch bed of cement concrete 3 feet wide under outer 



walls, centrally on this lay two courses of brickwork in 

 cement to a width of 18 inches, or build up to the same 

 height in concrete. 



Lay on this an approved damp-proof course, and on 

 top a further layer of brickwork so as to prevent fracture 

 of damp course when ramming.

formed, carrying them up plumb and true and properly 

 bonded by working rormd the ])uilding, course by course, 

 using the special angle and " T "-pieces at corner and 

 ]nid-walls so as to keep the work continuous and homo
