You will notice that no outlet is 
provided save by overflow and evapo¬ 
ration. For a small pond on a lawn 
these are sufficient, if one gives his 
basin good attention. 
The goldfish take 
who desires a 
must construct 
care of any troublesome larvse from 
the insect world, and the hotter the 
sun shines, the better the vegetation 
thrives. Every hard rain causes the 
basin to overflow and thus freshens the 
water, and in time of drouth and great 
evaporation the same effect may be 
brought about twice a day by means of 
the garden hose morning and evening. 
Of course he winters his tubs of lily 
roots in the cellar, and patches up his 
cement lining for the main basin every 
spring, to be sure that it is watertight 
for the season. 
The house owner 
more permanent tank 
one that is also more expensive. The 
two conditions which he has to meet are 
that the basin shall be absolutely water¬ 
tight, and that it shall be proof 
against frost. Concrete, com¬ 
bined with brick or stone, is 
undoubtedly the most satisfac¬ 
tory material to withstand the 
ravages of time and weather. 
A basin constructed with a solid 
concrete bottom and walls of 
brick, finished with cement, and 
flaring outward sufficiently to 
allow the expansion of the wa¬ 
ter within when it freezes, is to 
be strongly recommended. If 
the work is carefully done, such 
a pool will last for years, and 
it is sure to prove in the end no 
less economical than a cheaper 
ones which necessarily needs re¬ 
pairs more frequently. 
If the size of your property permits the establishment of a large pool its borders offer a splen¬ 
did opportunity for growing the many bog plants that are denied dry gardens 
The regulation depth for a

The central feature of a formal garden, depending on rains for 
its water supply. The drain pipe carries off the surplus 
sisantea, serve 
useful purpose in purifying the 
water. 
Judging from its beauty and 
the facility with which it adapts 
itself to varying climates and 
conditions, the most satisfactory 
plant for setting out in the pool 
is the Nyrnphcca, or floating 
Pond Lily. Especially hardy 
and well adapted for water-gar¬ 
dening is the Nymphcea odorata, or common sweet-scented white 
Water Lily, which is native to ponds, shallow borders of lakes 
and the edges of placid streams all through the eastern half of 
the United States. Once well established, it will thrive almost 
anywhere, and its fragrant blossoms and glossy pads are a con¬ 
stant delight to the eye from June to September. 
Included among the hardy Nymphceas are several varieties of 
colored Lilies which afford a charming contrast when planted in 
combination with the white species. One of the very earliest 
kinds is the Marliacea rosea, a lovely rose-colored Water Lily,, 
which often makes its appearance long before the Nymphcca- 
odorata has begun to put forth buds, 
is among the most satisfactorv of all

beauty of a placid pool is not allowed to be spoiled by too much

also an early and persistent bloomer. Both are strong growers, 
and so hardy as to require very little protection even during the 
cold winter months. Except in climates where there is danger 
of a pond freezing to the bottom, any of the Nymphceas named 
may be safely left uncovered. North of New Jersey it is usually 
a wise precaution to drain the water from the lily-pool in the-.
