Many boys and girls of these days are fortunate in having had at school an observation hive. No bee-keeper will be long without one if he has any curiosity about what is going on in the dark hive, or if he is ambitious to solve some of the mysteries. An ordinary hive can be made into a good observation hive by putting a pane of glass in the sides and top. There should be hinged doors to fit tightly over the glass. A two-frame hive devised by Prof. V. L. Kellogg has both sides of glass so that the whole domestic economy of the bee family can readily be observed. DISEASES AND ENEMIES You will not be in the bee business long before you learn that bees have diseases and enemies. In fact, it is better to face that fact at the beginning and learn how to recognize and combat the troubles. Carelessness along this line is inexcusable and will surely cause failure. Several states have official inspectors whose business it is to know bee diseases and methods of controlling them. He is required to inspect apiaries where diseases are suspected, and the best thing to do is to interest him in your work and get all the help from him you can. An ounce of prevention will save a pound of cure, every time. If there is a Bee-Keepers' Association in your county, by all means join it and help make it a live, active organization. The United States Department of Agriculture can give you much needed information as to who the men are in your locality who are officers in the associations and official inspectors. MARKETING HONEY The best honey market is the home market as I have said. You may have to work up a demand in your neighbourhood and there are many ways to do this which ingenious boys and girls will devise. Most of us, if we can afford to use honey at all, know it only as a "spread" for hot biscuits or griddle cakes. But not every one knows that honey is a very much more wholesome sweet than cane sugar. Many people cannot eat sugar at all, but find honey does not cause indigestion. If you could persuade your neighbours to buy your honey for their children instead of candy, "all-day-suckers" coloured with cheap dyes, and sirups made of nobody knows what, you would be doing something worth while. Honey is used in cooking too, in many ways. Get your mother or sister interested in trying some receipts in which honey takes the place of sugar. If you make a success of this you can get other people to making honey cakes, thus creating a demand for your product.
