T he plants in the water garden, just like 
all others that beautify your grounds, 
should be kept cultivated, fertilized and 
free from insects if they are to look their 
best. Scavengers are the housekeepers of 
the pool and relieve you of this responsibil¬ 
ity—fish feed upon the insects; snails de¬ 
vour algae and green scum; tadpoles eat 
decayed matter, and clams or mussels act 
as continuous filters to keep the water clear. 
For your convenience we are listing some 
of the most valuable and interesting scav¬ 
engers that keep pools and aquariums clear. 
See page 28 for oxygenating plants. 
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 25c: $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. 
3 for 25c; 85c per doz.; $6.00 per 100. 
CORAL SNAILS (Planorbis rubrum). These are the 
finest aquarium snails in existence, and their 
coral red body and shell makes them colorful as well 
as useful. Also known as Red Ramshorn or Copen¬ 
hagen snails. 3 for 25c; 85c per doz. 
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 sunli.ght. 5 for 25c; 50c per doz.; 
$3.50 per 100. 
MELANTHO SNAILS (Melanopsis graellsi). Long 
spiral shells like the “Horn of Plenty.” Active 
and hard scavengers. 3 for 25c; 75c per doz.; $5 per 
100 . 
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. 2 for 35c; $1.75 per doz. 
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 25c: $1.25 per doz. 
ASIATIC SALAMANDERS. A handsome type with 
black bodies and red vests. Like the above they 
are good insect-eaters. 2 for 50c; $2.50 per doz. 
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. 50c 
per pair ; $2.50 per doz. These must be sent in ship¬ 
ping can. 
TADPOLES. The younger generation of the frog 
family that grow legs the first or second season ; 
3 inches long; active in devouring decayed matter 
and green algae. Entirely harmless to either fish or 
plants. 50c per doz. ; $3.50 per 100. Shipping can for 
one dozen or less 25c; for more 50c. 
CLAMS or FRESH WATER MUSSELS. An effective 
remedy for green or cloudy water. The clam 
lives by filtering the solid nourishment out of great 
quantities 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 pooi. 3 for 25c: 
85c per doz. 
SPOTTED WEATHER FISH OR DOJOS. A curious 
eel-like fish 4 to 6 inches long with a curious 
habit of inhaling sand and blowing it back through 
the gills. It is a most excellent scavenger, besides 
providing a natural cultivation for aquatic plants. 
75c per pair; $4 per doz. Requires shipping can. 
BABY ALLIGATORS. Little alligators about 10 
inches long that soon become pets. They add a 
little Florida atmosphere. Will eat ordinary fish food. 
$1.50 each; $2.50 per pair.
