The principle is a combination of a support for the moss and a stream of spray to remove the dirt. It is made as follows: Prepare two shallow sieves, of any size desired (mine are eight inches square), of copper screen, flyscreen of 14 meshes to the inch is probably the best and is procurable everywhere. Make two frames of hard wood, one- fourth to three-eighths inch thick by one inch wide. Bevel one edge (the one which is to become the inside of the frame) and fasten the screen to

It is made as follows: Prepare two shallow sieves, of any size desired (mine are eight inches square), of copper screen, flyscreen of 14 meshes to the inch is probably the best and is procurable everywhere. Make two frames of hard wood, one- fourth to three-eighths inch thick by one inch wide. Bevel one edge (the one which is to become the inside of the frame) and fasten the screen to the wider side of the frame, so that the frame slopes inward to the screen, thus avoid- ing corners where loose plants can hide and making the screen more easily cleaned. The object of the frame is to prevent loose plants from floating away, and also to make the screen easy to handle. For very small mosses the screen should be finer, thirty, forty or fifty meshes to the inch or still finer if desired, though minute mosses must be washed with great care or they will vanish through the screen with the dirt. Next get a ''spray nozzle" and have it fitted to one end of a piece of strong rubber tubing or garden hose, the other end of which is fitted for being at- tached to the city water supply faucet, either by screwing on, or slipping over and tying. Mine I fitted to a garden hose-coupling so that I can use it as a hose nozzle or screw it on to any faucet fitted for the attaching of hose. There are many spray nozzles in the market, intended for use with ma- chines for plant spraying against insect depredations, for whitewashing, etc., and they are all essentially the same, but as they are intended for use with liquids con- taining sediment the opening at the point is too large for our purpose as the spray is too coarse and cone of spray is too wide. The Lowell Specialty Company, of Lowell, Michigan, sends out nozzles with its two-gallon hand tank apparatus which are very
