TRAPDOOR SNAIL 

Satie? 
CLAM WORKING IN SAND 






















E cannot say too much in favor of 
Weccvcnver: for your lily pool. Secav- 
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 29 for oxygenating plants. 
CORAL SNAILS (Planorbis rubrum). Known as 
Copenhagen Red Snails. These are the finest 
aquarium snails in existence, and their coral red body 
and shell make them colorful as well as useful. Also 
known as Red Ramshorn. 6 for 55c; $1.00 per doz. 
AUSTRALIAN RED SNAILS (Isadora proteus). 
Snails that are smaller and more active than the 
Coral variety. They are a bright scarlet in color. 
Their shell is curled like the African snail. An ideal 
aquarium novelty. 2 for 25¢; $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¢e; $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¢; 50c per doz.; 
$3.50 per 100. 
MELANTHO SNAILS (Melanopsis graellsi). Long 
spiral shells like the “Horn of Plenty.’ Active 
and hard scavengers. 6 for 55c; $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. 3 for 25ce; 85e 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. 20e each; 6 for $1.00. 
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 25¢e; $1.25 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 jish due to the water in Washington having been very heavily chlorinated. 
I shall certainly use these precautions.”
