 canals, and other improved modes of conveyance, together 

 with a proper accompaniment of blue slate, or at least the 

 factitious red pantiles, be transmitted to every town and 

 village in the kingdom ; whence the produce of perhaps 

 richer lands might be remitted in return, and in some degree 

 commensurate to the expense. 



Much also might be done by appropriate and judicious 

 planning; some houses containing by far more room, and 

 particularly useful room, than others under the same or a less 

 quantity of rooting. 



The danger of the slates being broken ; and the insuffi- 

 ciency of the putty or cement, to keep the joints weather- 

 tight, have been objected to Mr. Tugweirs pian. In answer 

 to this he points out a house thus covered in upward of three 

 years ago, which has remained during that time impervious 

 to wind, wet, or dampness of any kind from the air.
