POOL SCAVENGERS 
Scavengers perform a definite service in the pool. The snails eat algae and green scum; the tadpoles devour 
decayed matter; and the clams or fresh water mussels act as continuous filters to keep the water clear. 
76. LIVEBEARING TRAPDOOR SNAILS (Vivaparus malleatus). A 
large, hardy snail which bears live young and eats algae and 
green scum, keeping the water clear. One of the best scavengers 
for the pool. 
77. CORAL or RED RAMSHORN SNAILS (Planorbis rubrum). They 
are useful in aquariums as well as in pools and are very orna- 
mental because of their red color. 
78. BLACK SNAILS (Planorbis cornens). The same as the Red Snail 
except that the body and shell are black. A good scavenger and 
very prolific. 
-MELANTHO SNAILS (Melanopsis graellsi.) They have spiral 
shells like the ‘Horn of Plenty.’ They are very active and very 
hardy.

80. CLAMS or FRESH WATER MUSSELS. They are of great value in 
clearing up green water. A microscope will show that green 
water is minute bodies of algae. Mussels live by filtering great 
quantities of the green water and retaining the algae as food. 
They operate best in a few inches of soil or sand on the bottom 
of pool where they partly bury themselves. 
81. AMERICAN SALAMANDERS. These are harmless and interest- 
ing little fellows. Their back is a golden brown with red lines, 
and underneath they are brown with yellow spots. They feed on 
pond insects. 
82. TADPOLES. They are frogs in the larvae stage, and they are 
very active in devouring algae and decayed matter. 
ORNAMENTAL FISH FOR POOLS AND AQUARIUMS 
A water garden is always beautiful and picturesque, but when you add colored goldfish, then your pool 
becomes the most alluring spot in your garden. 
Aside from their ornamental value they are of great use for the extermination of mosquito larvae. They 
are also useful for eating the decayed leaves of the water plants. 
All of our goldfish are in perfect health and in good condition. Fish which are sold for pool purposes have 
been bred and raised outdoors. All of the goldfish listed below except the Fantails and Black Moors may be 
left outdoors during the winter. 
VERY IMPORTANT—PLEASE READ. The reason for the loss of 
fish, whether they are shipped by express or taken home from our 
place personally, is in most cases because of improper handling 
upon arrival. Even after the fish have been in the pool for several 
weeks, their loss may be traced back to the aforesaid cause. 
There are two important steps to be taken for the proper handling 
of fish and plants. First—The pool should be filled with water for 
at least three days before introducing the fish and plants. Second— 
The fish should be taken out of the container in which they are 
received and placed in the pool immediately after they arrive. 
During transit in crowded cans or containers the fish will use up 
all of the oxygen content of the water; therefore immediate transfer 
of the fish into a body of water with full oxygen content is abso- 
lutely necessary. 
Slight injuries or bruises are often unavoidable when fish are 
transported in cans or containers. This may make the fish easy prey 
for various fish diseases—especially fungus. To be prepared for 
such an emergency we recommend that you have on hand a bottle 
of our Argucide (see below). 
Caution, for Newly Constructed Concrete Pools the above mentioned 3 day old water does not apply. A newly constructed 
pool should be seasoned or cured by draining and refilling the pool at least five times for a period of two weeks. 
This seasoning or curing may be accomplished in a period of three to four days by the use of strong vinegar — 1 quart to 
100 gallons of pool water. After four days drain, clean thoroughly, and refill, allowing the water to stand for 3 days 
before introducing the fish and plants. 
83. SELECTED GOLDFISH. A fine strain of lively, brilliantly colored 
fish with beautiful markings of black, red, and silver. These 
fish are the best for mosquito larvae extermination. We wish 
to call your attention to the fact that 6 small fish eat more 
mosquito larvae than 1 large fish costing the same as the small 
fish. 
84. SELECTED COMET TAIL GOLDFISH. These fish are similar in 
color to the Selected Goldfish, but they have longer and more 
graceful tails and fins. 
Both of the above mentioned goldfish come in sizes of from 
2 to 7 inches. 
85. GIANT GOLDFISH. They are 8 to 10 inches long, and they have 
well developed fins and beautiful coloring. (Not suitable for 
aquariums or small pools.) 
86. CALICO FISH or SHUBUNKINS. The name Shubunkin means 
Autumn Brocade. These fish have all of the colors of autumn

surface which is constantly under water. It greatly enhances 
the beauty of the pool by taking away the drab appearance of 
unpainted concrete. It will also stop minor leaks, It is furnished 
in a beautiful shade of sky blue. 
foliage—red, gold, black, brown, lavender, white, and blue.

on red gold bodies. The tail is double and is spread like a fan.

but they have double, fan-like tails and short bodies.
