From Nos. 1 to 12, and usiiig boards 4 inches wide, with the upper eilges 

 straight, lay one from A to B and another from C to D, and drive pegs 

 in the centre space behind tliem, as at e, e, e ; then using short boards 

 3 ft. 4 in. long, place them three on each side, as at F, F, F, and fix tliem 

 in position with pegs as before. Note that these pegs are not to be in 

 tlie spaces to be filled with concrete: it is sometimes necessary to have 

 them so, Ijut they must lie removed, and tlie holes filled in with cement 

 mortar as soon as possible. 



Having the concrete mixed, hll in slabs Nos. 1, 3, !), and 11, keeping 

 the surface lightly rammed down h inch below the edges of the l)oards, to 

 allow for the top-dressing. These should be allowed to set for, say, 

 twenty-four hours, when the top may be finished off, trowelling hard with 

 a steel trowel for a smooth face, or with a wood float or trowel if required 

 for a rough face. Cut off the corners half V shape ; tlien take up the 

 short boards and place a strip of strong brown paper against the edges 

 of tlie finished slabs; fill in Nos. 2, 4, 10, and 12, allow to set, and finish 

 as before, then Nos. 5 and 7, then 6 and 8, and the floor is laid in twelve 

 separate blocks that will, if the stuff has been properly mixed and a liberal 

 amount of elbow-grease used, never crack or wear out. The quantities 

 of material reijuired for tliis floor would be — 



\\ cubic yards stone, broken to li-inch gauge; 



J cubic yards clean sand ; 



(') butj's or two casks Portland cement.
