gray-green joint and will delight with its fra- 
grance when trodden upon. Mrs. Wilder has 
spoken of this in previous issues. In an old 
English walk. Thyme is planted alternately 
in squares with square stones and trimmed into a 
regularity which matches the stone, so that you 
are reminded of paving in light and dark marbles. 
And as you walk, the delightful resilience of the 
mats of Thyme is most grateful to tired feet, 
and the clean sweet fragrance of the bruised 
leaves is like balm to tired nerves. Why do we 
not have more such quaint features in our 
gardens to lift them above the commonplace?

MAKING A WATERPROOF 
CONCRETE POOL 
IT REALLY is a simple matter. The best 
1 method is of course to use concrete that is 
per se impervious to water. A mixture which is 
proportioned so as to be rather rich in cement 
or one part Portland cement, two parts clean sand 
and three parts pebbles or crushed stone will 
give the desired result. The concrete is mixed 
mushy wet and well spaded, tamped, and churned 
into the forms, so as to secure a very dense, well 
compacted concrete. To concrete such as this, 
designed especially to be watertight, it is some- 
times the practice to add one-tenth part hydrated 
lime, i. e., one-tenth of the volume of cement. 
Hydrated lime acts as a void filler and tends to 
make the mixture more plastic and dense. 
When concrete work is done along the lines 
described with careful attention to all details, 
no additional waterproofing is required. This 
has been proven by tests of the U. S. Government 
Bureau of Standards which finds after a long series 
of tests that such concrete is impervious to water 
pressure up to a head of 40 feet. 
COMPOUNDS USED IN THE MIXTURE 
If waterproofing compounds are to be used 
it should be remembered that there are two 
general methods of waterproofing: first, integral 
method; and second, surface treatment. In 
the integral method the waterproofing is mixed in 
with the concrete and consists of some material 
which acts either as a void filler or as a water re- 
pellent. 
The waterproofing in the surface treatment 
method consists of paints of paraffine or asphaltic 
nature, or by some compound which will react 
with the cement, such as sodium silicate or water- 
glass. For extremely bad conditions where the 
work is underground (such as tunnels under 
rivers), it is the practice to use a membrane 
waterproofing which consists of several layers of 
burlap or felt mopped on alternately with layers 
of coal tar pitch or other bitumen. 
As regards the method of waterproofing neces- 
sary for the construction of a concrete pool for 
Water-lilies and smaller uses, there would be no 
special precautions necessary except to use a 
mixture of 1:2:3 well mixed and tamped and 
spaded into the forms. It would of course be 
best to build the bottom of the pool and the 
walls monolithic, i. c., to place the concrete con- 
tinuously without stop; and this is entirely 
practical for most small pools.
