The reason we are explaining the uses of these fertilizers to you 
in detail is because many cases of fungus growth or other goldfish dis¬ 
eases are almost entirely due to the use of wrong fertilizers as all kinds 
of fresh manure will further the growth of bacteria such as the fungus 
diseases. 
We have listed in our catalog a Water Lily food which we have 
developed over a period of years which gives complete satisfaction as to 
Water Lily root growth and complete satisfaction in the prevention of 
the fungus growth. This Water Lily food is listed elsewhere in this 
catalog under the trade name of "Magic Water Lily Food” and sells 
in one pint cartons, 35c each or in five-lb. bags, #1.05 each. A one pint 
carton will be enough for one bushel of soil.

HOW TO PLANT WATER LILIES 
The planting of water lilies is not really very different than the 
planting of any other kind of plants except that you set them under 
the water. Many people make the mistake of filling the pool after 
they have planted the water lilies. The best way to plant water lilies is 
to have all the boxes in their proper positions and then fill the pool 
with water so that the water is about four or five inches above these 
boxes and leave it at this level until you plant the lilies and until the 
water lilies have started to grow. Then turn the hose on the pool and 
fill it to its proper level. Newly planted water lilies will make a much 
quicker growth in shallow water than in deep water especially since most 
of the water lily planting is done in the early spring of the year before 
the water gets real warm and shallow water planting will produce the 
quickest and best results. One of the common mistakes made in the 
planting of the pool is that people will put the soil all over the bottom 
of the pond. This method is successful from the standpoint of planting 
water lilies only, but not very good from the standpoint of keeping 
goldfish in the pool and keeping the water clear. Another thing is 
that it is almost impossible to clean the pool. We prefer to plant every¬ 
thing we put into a pool in boxes or pots. Never use any kind of metal 
containers. It is also better to rest the lily boxes off from the bottom 
of the pool. This may be accomplished through the use of bricks or 
rocks. You can arrange the level of the boxes so that the top of the 
box will be about six inches below the water surface. Then, in the 
winter time, you can lower this box if you leave them outdoors if you 
live where the winters are quite severe. Thus, according to our direc¬ 
tions, you would have nothing but a clean concrete bottom in the pond; 
no gravel, no sand, and no dirt and when you want to clean the pool 
you will have the minimum amount of labor to perform and can do

the job more efficiently. As a rule, a pool in which everything has been 
planted in boxes does not need cleaning more than once a year. The 
best time to clean your pool is in the spring of the year when the water 
begins to get warm after it has attained a temperature of not less than 
50 degrees F. It is not a good policy to handle the goldfish until after 
they have completely recuperated from their winter rest. 
THE CARE OF GOLDFISH 
While we cannot go into the details of breeding and propagating, 
etc., as this would be too lengthy a subject. We would like to call your 
attention to a small booklet, "Goldfish and Their Care”, which we have 
listed in this catalog and which can be sent to you for 15c, postpaid. 
Planting things on the bottom of the pool in pots or boxes is to be preferred to 
placing soil directly in the bottom of the pool. It is easy to make small wooden 
boxes or you may use the regular fern pots which are squat shape flower pots. 
They do not tip over as easy as the standard size pots.
