Tappan receptable from which the fish wih be taken; regulate the degree of heat by adding hot water to that in the pitcher or bucket, and not by pouring direct into the tank—the hot water would be apt to crack the glass. We now have reached the stage wherein lies success or failure—the plants. The fault most general with be- ginners ec(uipping their first tank is that they are niggardly when it comes to in- vesting in plants. They will buy quite a nice tank, spend perhaps several dollars for fishes, but only a few cents for plants. In other words, they propose to build their water world on a very insecure foundation. The plants, the very essen- tial to its success, they economize on; the greatest mistake it is possible to make in fitting an aquarium. It would be far better if they regarded the aquarium as first an aquatic garden, and then, second- ly, as a home for fishes. There are just a few species of sub- merged plants that may be regarded as "foundation" plants. The first in this class is Sagittaria (several species or varieties), with J^allisneria a close sec- ond. The latter will thrive with consid- erably more sunlight than the former will find agreeable, but neither will thrive without sufficient light. Both are domi- nant plants in the tanks of experienced aquarists and propagate readily by means of runners from the roots. These spe- cies cost from ten to twenty-five cent- per plant. The cost, considering the size of the individual plant, seems high, but as they increase in number more or less rapidly throughout the year, and are the best oxygenators in consequence, they are
