So Easy to Build 
With these sketches any handy man can, with the ordinary 
laborer, build pools at practically no expense other than the cost 
of material. No high-priced mechanic is necessary. 
Pools may be constructed with straight or curved lines. If you 
have a good clay bottom you can lay the cement on the clay; if 
not, we suggest that you put in six inches of cinders beneath the 
cement bottom. Be sure to have the cinders well packed. The 
construction can be made by any cement worker. The overflow 
and drainage pipe should be the same. A short piece of pipe with 
thread on the end can be screwed into the drain pipe. 
The ideal water pool is about two feet deep. The side walls 
should be about five inches in thickness, tapering to seven inches 
at the bottom. The bottom of the pool need not be more than 
six inches. 
Good results can be obtained from a mixture of one part Port- 
land cement, two parts sharp sand, and three parts half-inch gravel 
(if gravel is not available crushed stone may be used), mixed with 
water and poured over the bottom and up the sides. The rough 
places of the concrete may be smoothed down by applying a thin 
coat of cement with a trowel or paint brush. It is important to 
keep newly poured concrete moist for several days by sprinkling 
frequently several times over a period of ten days, before any fish 
or plants are placed in it, as the alkali may injure the fish and 
plants. (Your local cement dealer will gladly give you a pamphlet 
on “Cement Construction.”’) 
Your pool should be carefully washed out before planting. 
Should a green scum appear, this will be due to vegetable growth 
and will disappear in a short time. Do not change water and 
above all do not add chemicals, as these will injure both the 
plants and fish. If absolutely necessary flush the pool, and if 
this does not clear it up, use our algae treatment. 
No flower can be produced at so 
little cost as the most fascinating and 
gorgeous Water Lily. Pools can 
now be built at so little expense that 
anyone who has the room and the 
sunshine may now have the oriental 
beauties of the water garden at their 
own home.
