GARDENING FOR BEGINNERS 



(and something less at the back, owing to the slope of the 

 bottom), while if the valve is opened, no water whatever will 

 remain in it. Care should be taken to carefully guard the 

 inner side of the valve, say, with perforated zinc, or, better 

 still, perforated brass. The next thing to do is to put in 

 about 5 inches or 6 inches of broken stone or brick of about 

 the size of an orange, and on this a layer, 2 inches thick, of 

 stones, just large enough to roughly cover over the interspaces

between the lower "rough stuff," and so prevent finer soil 

 from choking up the drainage (see Fig. 14). 



The Best Soil. Upon this intermediate layer the moraine 

 soil proper should be laid, of sufficient thickness to entirely 

 fill the moraine, and should consist preferably of sandstone 

 chips put through a half-inch or three-quarter inch mesh 

 sieve for the lower part and a quarter-inch mess sieve for the 

 upper. If there are fine particles in this, as there probably 

 will be, it is advisable to put the whole through an eighth of 

 an inch mesh sieve to get rid of the dust, which so readily 

 clogs the drainage. Just a suspicion of well-decayed leaf-soil 

 may be added to the top 6 inches, say, one part to fifteen of 

 stone chips. If the boundary walls of the moraine have been 

 arranged in an irregular outline and have been topped with
