Ponds dug into the earth or constructed by dams are Jess expensive 

 than those built of bricks or concrete, but the latter are more easily super- 

 vised, as the perpendicular sides offer a clear view of the contents and 



protection from the direct rays of the 

 sun during hot afternoons. However 

 constructed, shrubbery and shade trees 

 should be planted along the banks 

 and a luxuriant growth of water plants 

 encouraged in them, restricted to 

 localities where they will be under 

 control. For this purpose Cabomba, 

 Myriophyllum, Giant Anacharis and 

 Ludwegia mulerttii are best and will 

 find a ready market; but floating 

 bunches of watercress will root and 

 thrive on the surface, furnish oxygen 

 and offer convenient hiding places 

 and shade for the fishes and homes 

 for the small aquatic fauna constitut- 

 ing the natural food; having the ad- 

 ditional advantage of ready removal 

 when desired. No plants other than 

 these and lilies should be introduced 

 or permitted to grow. Sagittaria 

 will not grow out-of-doors. All sod 

 should be removed from the bottom 

 and the sides at the water level to prevent the injurious decay of vegetable 

 matter. 



Feeding tables in the water are not advisable as they may become 

 foul from decaying matter, culture places for parasites and safe retreats 

 and lurking places for enemies which shun the light of day. The fishes 

 soon learn to congregate in the desired localities at the regular feeding 

 time and will keep the bottom clean and clear of food, if not overfed. 



Let it here be again noted that goldfishes of the fine breeds become 

 more course in large bodies of water than those reared in small tanks and 

 basins. 



Specially Equipped Goldfish Breeding Establishment. The 

 illustration, Fig. 60, is an ideal arrangement for a large artificially con- 

 structed breeding establishment for fine fishes. Its location would best be 

 in the country near an abundant supply of clear, moderately cold-water.
