E cannot say too much in favor of 
scavengers for your lily pool. Scav- 
engers are the housekeepers of the 
pool and water garden. Your fish feed 
upon insects; snails devour algae and 
green scum; tadpoles eat decayed matter, 
and clams or mussels continuously filter 
the water to keep it clear. All this helps 
to keep your pool healthy—free of in- 
jurious insects which harm plant life, 
making your pool clear and attractive to 
the eye. 
For your convenience we are listing some 
of the most valuable and interesting scav- 
engers that keep pools and aquariums clear. 
See page 19 for oxygenating plants. 
CORAL SNAILS (Planorbis rubrum). Known as 
Copenhagen Red Snails. These are the finest 
aquarium snails in existence, and their coral red 
bodies and shells make them colorful as well as use- 
ful. Also Known as Red Ramshorn. 6 for 65c; $1.25 
per doz. 
LIVEBEARING TRAPDOOR SNAILS (Vivaparus 
malleatus). These large, hardy snails should be 
in every pool and aquarium. They devour algae and 
green scum and thus help to keep the water clear. 
6 for 55¢; $1.00 per doz.; $6.00 per 100. 
BLACK RAMSHORN SNAILS (Planorbis corneus). 
Medium sized snails with shell characteristic of 
the name. Very prolific egg layers and particularly 
useful in removing the algae or green scum that 
forms in the sunlight. 5 for 25¢; 50¢ per doz.; $3.50 
per 100. 
MELANTHO SNAILS (Melanopsis graellsi). Long 
spiral shells like the ‘“‘Horn of Plenty’. Active 
and hard scavengers. 6 for 55¢; $1.00 per doz.; $6 
per 100. 
MYSTERY SNAILS. A new and unusual snail, very 
useful and interesting. They lay their eggs above 
the water on plants or glass. 6 for 55¢; $1.00 per 
dozen, 
GEOGRAPHIC TURTLES. The most popular item in 
this list though admittedly more ornamental than 
useful. Little fellows about two inches across and with 
curious mosaic or maplike designs on both upper and 
lower shells. Like all water turtles they like to sun 
themselves and while waiting for lily pads to grow, 
they should have a rockery or floating board for this 
purpose. 35¢ each; 6 for $2.00; 1 doz. $3.85. 
AMERICAN SALAMANDERS. A harmless species of 
water newt that may or may not be fireproof like 
its fabled ancestor. Golden brown with red lines and 
black dots on the back; yellow spotted with brown 
beneath. Closely related to the frog and fond of 
insects. 2 for 35¢; $1.75 per doz. 
J. Edgar Hoover writes— 
“The fancy goldfish have arrived, and in excellent 
condition. I wanted you to know how much I appre- 
ciate your making this replacement. Also, I want to 
thank you for your kindness in giving me the advice 
for the treatment of the fish due to the water in 
Washington having been very heavily chlorinated. I 
shall certainly use these precautions.” 
J. Edgar Hoover, Director, 
Federal Bureau of Investigation, Washington, D. C.

FOR POOLS AND AQUARIUMS 
GREEN FROGS. Ornamental, likeable, and the best 
insect trap ever known. When we see lily pads 
we expect to see a bull frog nearby. Any size. 60¢ 
per pair; $3.25 per doz. 
TADPOLES. The younger generation of the frog 
family that grows legs the first or second season; 
3 inches long; active in devouring decayed matter 
and green algae. Entirely harmless to either fish or 
plants. These must be sent in water. %5¢ per doz.; 
$5.00 per 100. 
CLAMS or FRESH WATER MUSSELS. An effective 
remedy for green or cloudy water. The clam lives 
by filtering the solid nourishment out of great quan- 
tities of water, leaving it crystal clear. They operate 
best in a few inches of soil or sand where they travel 
about occasionally and feed with shell or edge half 
buried in the earth. Use plenty of them and notice 
the difference in your pool. 6 for 75¢; $1.40 per doz.; 
$10.00 per 100,

SNAILS (Collection No. 34-C) 
It is difficult to get too many snails, per- 
forming as they do the useful function of re- 
moving decaying vegetation and particularly 
the green scum-like growth of algae. Use two 
snails per square foot of bottom 
area. 100 assorted snails. $5.00 
Golden Orf is a rare fish, and a brilliant one for your pool. 
They are constantly active. Golden Orf’s orange color on 
its top-side and yellowish gold undermarkings make it very 
striking in appearance. They often leap out of the water 
after insects. This native of Europe is extremely hardy— 
more elongated and cylindrical in shape than goldfish, and 
being very peaceable, can be kept right in the pool with 
goldfish.
