CONSTRUCTION OF WALKS AND DRIVES IO7 



The gardener with command of this class 

 of material might use it in the form of stepping- 

 stones, as the Japanese do, but the effect so 

 obtained must not be overdone. Its legitimate 

 place is on the grass. 



Note — In the use of a non-binding material 

 like blue stone it is well to screen out all 

 fine stuff which otherwise would adhere to 

 the boots in wet weather and be carried into 

 the house. Shells form an almost hopeless 

 material for the garden. Their innate friability 

 precludes the separation of large from small, 

 and renders them the most persistent material 

 I know of for finding Its way Indoors.
