 fir joists, i^laced 16 inches from centre to centre, 

 framed with trimmers to all fireplace and other

 work i)roceeds, and secured thereto by means of 

 an iron cramp turned up and down to every other 

 joist ; care to be taken that the concrete is per- 

 fectly level to receive joists, as no bond timber is 

 intended. The concrete should rest uj^wn the 

 upper edge of the joists, but the sides and ends 

 should be kept clear, so as to prevent dry rot. 



Insert cast-iron air-bricks in the outer walls on 

 opposite sides, and bore holes through the joists 

 in a line therewith, so as to allow a free circulation 

 of air.
