SCAVENGERS for the Pool or Aquarium 
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 responsibility—fish feed upon the 
insects; snails devour 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 
scavengers that keep pools and aquariums 
clear. See page 33 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. 
JAPANESE 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. 2 for 
25c; $1.25 per doz.; $7.50 per 100. 
CORAL SNAILS (Planorbis rubrum). (Illus¬ 
trated in color on page 41). 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 or Copen¬ 
hagen snails. 2 for 25c; $1.25 per doz. 
BLACK RAMSHORN SNAILS (Planorbis cor- 
neus). Medium sized snails with shell char¬ 
acteristic of the name. Very prolific egg layers 
and particularly useful in removing the algae or 
green scum that forms in the sunlight. 4 for 25c; 
60c per doz.; $4 per 100. 
MELANTHO SNAILS (Melanopsis graellsi). Long spiral shells like 
the “Horn of Plenty.” Active and hardy scavengers. 3 for 25c; 
75c per doz. ; $5 per 100. 
GREEN FROG 
WEATHER FISH 
BABY ALLIGATOR 
Plan now to have an 
aquarium. Place in it some 
of these scavengers and a 
collection of our Tropical 
Fishes and you will be de¬ 
lighted with the fascina¬ 
tion and beauty of it. See 
page 43. 
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 shipping can. 
TADPOLES. The younger generation of the frog 
family that grow legs the first or second sea¬ 
son ; 3 inches long; active in devouring decayed 
matter and green algae. Entirely harmless to 
other fish and 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 effec¬ 
tive 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 
pool. 2 for 25c; $1.25 per doz. 
WEATHER FISH. 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. $1.00 per 
pair ; $5.00 per doz. Requires shipping can. 
BABY ALLIGATORS. Little alligators about 10 
inches long that soon become pets. They add 
a little Florida atmosphere. As they like tadpoles, 
stock your pool well. $1.50 each; $2.50 per pair.

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

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

AMERICAN SALAMANDERS. A harmless species of water newt 
that may or may not be fireproof like its fabled ancestor. Golden
