The chief disadvantage is purely a matter 

 of cost, though this is often a rather important 

 point. The labour of digging out the garden 

 and, in all probability, of having to cart the rocks

 are fortunate indeed who have the rocks close 

 at hand, and only those w^ho have had to 

 draw their supplies of stones from a distance

The merits of the sloping bank and knoll 

 types are, that if the ground has the necessary 

 conformation, the only labour entailed is to 

 clear the surface of scrub and weeds, and to 

 place the rocks in position ; therefore, unless 

 any unforeseen difficulty should arise, they are 

 probably the least costly types to make, but 

 at the same time they are not so effective as 

 are some of the other forms. 



As regards the old sand- or gravel-pit, pretty 

 well the same remarks apply to them as the 

 foregoing, except that in these cases soil may 

 have to be procured in addition to rocks, and 

 perhaps, the outline being bolder, better effects 

 may be obtained.
