An unbroken earth bank covers the dam before the foun- 
dation “steps” are cut for the concrete foundation 
stone, as it is laid, and ram this in between the 
joints with a sharp stick. The stones in most 
cases should overlap the ones below them; and 
special ones should be selected with care (and by 
actual trial with water) for making the water 
leap clear at certain places on its way down. 
It is important, as you build up, to make al- 
lowance for soil pockets for various kinds of plants 
— small ones for the creepers, rock plants and 
ferns, and occasionaly ones large enough for an 
evergreen or shrub. What these plants them- 
selves shall be it is a little hard to suggest be- 
cause localities differ so greatly. It is safe to 
say, however, that the wild plants growing near 
you are best, with the addition perhaps of 
some few special things if a certain color or foli- 
age effect is desired. 
Without doubt one of the most beautiful objects in the world is a cascade, 
and to create a rockbed which will break up and attenuate into such misty 
loveliness as this, the pent-up waters impatient for their liberty, is an 
achievement bringing man into worthy competition with Nature at her best 
The final touch is the planting, done 
of course before the water is turned 
in — and in this case, largely evergreen 
To form the pools at the top of the fall the rocks must be 
very carefully laid, and at every point the angle as well as 
the exact position of each is a matter of patient consideration
