Artificial Rain in Mr. Burbank's Garden
The kind of sprinkling apparatus that Mr. Burbank uses and recommends is that here shown. It consists of long pipes, attached to a hose, the pipe having little nozzles at intervals of a few inches, and thus sending forth a series of tiny streams which, rising high In the air, descend on the plants in a shower that closely simulates rain from the clouds. The pipes can be turned to throw the spray in either direction, and to regulate the distance at which the shower descends. Remember always that water is food for the plants, absolutely indispensable food.
