1. Make a dry mix of about 1 part Portland 
cement, 2 parts clean sharp sand, 2Vz to 3 parts 
clean gravel. Mix thoroughly until the color is 
uniform—no gray or brown streaks. 
2. Add correct amount of water and mix until 
sand and pebbles are thoroughly coated with cement 
paste. 
The concrete should be placed within 30 minutes. 
Placing the Concrete 
Oil the inside of the forms so that concrete will 
not stick to them. First place the concrete for the 
floors. Then deposit the concrete for the walls in 
6 or 8-inch layers all around the pool, spading each 
layer as it is placed. A garden hoe, straightened out, 
makes a good spading tool. 
Often, pools are built partly above grade. A 
foundation two or three feet deep should be used. 
Curing 
Do not permit newly placed concrete to dry out. 
Protect it from sun and drying wind for a week to 
10 days. A covering of burlap or canvas, sprinkled 
often enough to keep it moist, is a satisfactory cov¬ 
ering while curing. 
The Miniature Pool or Tub Garden 
Only your ingenuity and the space you have available limit you in 
designing your lily pool. It can be formal or informal to harmon¬ 
ize with the general arrangement of your garden. Interesting 
effects can be obtained by setting native rocks in the concrete. 
Plan and cross section of a simple garden pool. 
The most inexpensive is the tub garden. Not 
much room is needed—only three or four feet 
square makes a very nice, small water garden. 
Choose a sunny spot and sink a wash tub or half 
barrel in the ground. Two or three tubs are some¬ 
times grouped together filling in the space with 
perennials or rock plants. The tub should be filled 
with five or six inches of good garden loam with a 
big handful of commercial fertilizer well mixed in. 
At intervals of three weeks a spoonful of fertilizer 
added to each plant will tend to produce more 
blossoms. 
Almost finished—an interesting small pool built without forms 
by plastering the concrete in place.
