which water could not find its way ; and we should thereby 

 avoid the, at times, disastrous and disintegrating effect of 

 rain and frost. 



We endeavour in road making to ai)proximate to this 

 ideal surface by breaking the stone into small ])ortions or 

 cubes in order that a concrete mass may be formed with 

 as few and as small voids or interstices as possible. 



The smaller the stone the more continuously solid is 

 the resultant surface ; but it is obvious that however 

 small the pieces of metalling may be there will always 

 exist interstices or voids; and to minimise such by a hard 

 and binding substance, as hard as the metalling itself, 

 ought to be the object of every one laying down a road. 



This can be accomplished by the substitution of Clee 

 Hill Dhu Stone Screenings for road siftings, clay, or 

 earth. The voids are thus filled up and each cube is 

 firmly wedged in position by an imperishable material : 

 the surface is at once made flat and free from the rough- 

 ness which would otherwise exist, and in a short time 

 the road will be composed throughout of the one solid 

 and unyielding Dhu Stone, possessing a watertight surface, 

 the importance of which cannot be exaggerated. A road 

 was so laid down giving access to these quarries .some 

 four years ago, and has not since been touched. 



I can recommend the system on the ground of its 

 economy, permanence, and ease of traction; such a road 

 being superior to the one made in the ordinary wav. The 

 small vacant spaces otherwise filled up with earth, clay, or 

 debris, become, in times of wet succeeded by frost, the 

 equivalent of so many dynamite charges, which burst and 

 disintegrate the road. 



I may not be helping the Stone Companies by this 

 recommendation, but anything which will tend to cheapen 

 road construction and maintenance and to give better 

 roads will, I believe, result in a still more extended use of 

 the stone.
