6, YORKSHIRE. i^t; 



The particulars which now remain to be 

 noticed under this head are, 



1. The method of laying pantiles. 



2. The method of coping ridges and 

 cables. 



3. Eaves gutters. 



4. Water cifterns. 



5. Painting window-leads. 



6. Mortar floors. 



1. Laying Pantiles. Formerly it was 

 the practice to hang pantiles upon the naked 

 fpars, bedding their ends in mortar, and 

 pointing them at the fides to prevent Ihow 

 and rain from being beaten through between 

 them. 



This method had two evil effedts : lime 

 is liable to expand, contract, and pcrifh 

 with the weather ; to which in this cafe it 

 is fully expofed. The confequence was, if 

 the cement laid faft: hold of the tiles it broke 

 them ; if not, it Aid from between them, and 

 left the attic room expofed to the weather. 

 The other bad efTcd: of this method is, their 

 being liable to be thrown off in high winds 

 by the inward air being pent up, and finding 

 an eafy pafl'age through this flight covering *.
