THE ROCKWORK 65 



economical reasons only. Quarried stone will 

 give more pleasing results, and is easier to build, 

 the faces of the stones working in better 

 together than is the case with those rounded 

 by the action of the weather or water. Some 

 people indeed object to the freshly hewn rock 

 as looking too new, but the advantage of 

 having rocks that will join closely together 

 more than makes up for this, and a couple of 

 years will give the desired weather-beaten 

 appearance. 



It is impossible to build rocks with 

 rounded surfaces properly together, for, being 

 invariably convex, it follows that on either 

 side of the point where they touch there must 

 be a gap, which has to be filled up somehow 

 or other with small stones. This is seldom 

 satisfactory, for frost and rain have a marvellous

The rock for building should consist of
