 the bolder the effects obtained. All sizes can 

 be used, weighing from a few pounds to a ton 

 or more. A good building material is about 

 15 or 20 rocks to a ton. 



Not only do I recommend quarried stone, but 

 go so far as to say that it should all come, not

 same part of it ; for you will then get both a 

 uniform colour and strata, which will to a great 

 extent simplify the building and also give the 

 ultimate rockwork a more natural appearance. 

 It should never look like a collection of geo-
