Agricultural Experiment Station; Agriculture -- New York (State). 49 Experience, the dear but thorough teacher, is of more value to every one of us than many rules and precepts. Nothing can rob us of the pleasure that comes of finding things out for ourselves. Much of the fun as well as much of the success in life comes from over- coming its difficulties. One must have a large store of patience and courage and hopefulness to undertake the care of an aquarium. After it is once made it is less trouble to take care of than a canary or a pet rabbit. But most things that are worth doing require patience, cour- age and hopefulness, and if we can add to our store of either by our study of life in an aquarium we are so much the better for it. Two kinds of aquaria will be found useful in any school. Perma- nent ones—those which are expected to continue through a season or through a whole year if the schoolroom is warm enough to prevent freezing; and temporary ones—those which are for lesson hours or for the study of special forms. If some one phase in the life of any aquatic animal is to be studied during a short period, it is well to have special temporary aquaria. Also when a talk on some of the occupants of the larger aquarium is to be given, speci- mens may be placed in small vessels for the time being and returned later. For such purposes glass tumblers can be used, or small fruit jars, finger bowls, broken goblets set in blocks of wood, ordinary white bowls or dishes, tubs, pails or tanks for large fishes, in fact any wide-mouthed dish which is easy to get. Special suggestions will be made in connection with the study of some of the water insects and others. A permanent aquarium need not be an expensive affair. The rectangular ones are best if large fishes are to be kept, but they are not essential. Here again, it is easier to write directions for the construction of a perfect aquarium, tha
