42 THE STORY OF MY ROCK GARDEN 



On the top of this layer I placed the moraine soil 

 proper, consisting of sandstone chips, largely augmented 

 by broken brick and tile, which makes an excellent 

 substitute when sandstone is at a premium. I put the 

 whole of these chips through a half-inch sieve for the 

 lower portion of the soil, and a quarter-inch sieve for the 

 upper layer, while to eliminate the dust particles from 

 among them, which would very readily clog the 

 drainage, I passed the whole through a one-eighth of an 

 inch sieve. By this means I introduced into the moraine 

 clean sharp grit only. 



Into the upper six inches of the moraine soil I mixed 

 the merest suspicion of well decayed leaf-mould, 

 probably about one to fifteen parts of stone chips. 

 One of the illustrations on page 37 gives an idea of the 

 appearance of the two compartments, when the bottom 

 layer of " rough stuff " was in one, and the bulk of the 

 finer chips in the other. It also shows the dividing 

 wall topped with decorative pieces of stone, and illus- 

 trates the irregular form of that wall, which allows the 

 topping stones to make an irregular line, when the 

 moraine is completed. 



The second illustration on the same page gives an 

 idea of the appearance of the moraine immediately after 

 it was finished and planted. Most of my moraine plants 

 being very small, I fear there is visible in most cases 

 more label than plant, at this early stage. My water
