As might be expected of animals which have for so many centuries been associated with man, goldfish have a good many diseases. Their ill-health can almost invariably be traced to neglect or ignorance on the part of the person upon whom they are dependent. The signs of ill-health are usually quite noticeable. They are: Faded colours, bloody streaks, coated or inflamed fins, and swollen gill covers. Most of the troubles have to do with air supply. When a fish loses colour and appetite, has a slimy coating, and acts weak and dejected, it should be put into a "hospital" aquarium where plenty of plants are flourishing, at a temperature of seventy to eighty degrees Fahr. One teaspoonful of salt to each gallon of water will be good for the fish, but no food should be offered for several days. This remedy will usually restore the fish if its trouble is asphyxia or itch and has not gone too far. In the open water conditions right themselves more readily, but fish acting queerly should be taken out from among the others. The greatest harm may result from hail storms and heavy rains on unprotected tanks. The natural enemies of goldfish inhabit the same ponds and to succeed one must daily wage war against crayfish, tadpoles, salamanders, snakes, fish-eating birds, muskrats, and aquatic insects. Toad and frog spawn found in goldfish ponds should be removed to some other pond to mature. These creatures are useful as destroyers of insects but you can dispense with them in goldfish tanks. THE STORY OF A BOY'S ANIMAL CAGE Two years ago, when I was ten years old, my father built me a house for my animals. It is twenty feet square and ten feet high. The framework is of wood. The walls are covered with wire netting. In winter they are boarded in. Last winter we had a fire in a stove in the passageway, but we decided that the animals were better off without it. The pen cost about one hundred and fifty dollars. I keep in it three 'coons, ten to thirty rabbits, and about twenty pigeons. Two 'coons, Tom and Jerry, I have had three years; the other one, Pauline, I have had two years. My oldest rabbits, Harry and Lily, I have had six years. The 'coon pens and the passageway have wooden floors. The walls of the 'coon pen have double wire to prevent the 'coons from grabbing the other animals. Their pens go up to the roof of the house. The rabbit pens are separated by movable wire panels six feet high. On this side of the house there is a second story for the rabbits and pigeons. This is reached by a step-ladder, and is divided by movable panels. The pigeons' house is over the passageway. There are shelves with nappies in them for nests. It is open at both ends in summer. I have kept crows and white rats; they were not a success. The crows killed the rabbits, and the rats smelled bad.
