Syringes
A Syringe is especially required in glass structures for dewing or washing fruit-trees and plants in general at some part of their season of growth. It requires careful handling, and the barrel should not be knocked against any hard surface, which would cause in-dentations, and prevent the piston from working properly inside. The best Syringes are usually provided with two, or even three, movable roses of different kinds, any one of which may be used according to the force of water required. The kind most generally useful is that with a nozzle in which a ball is placed. When the piston-rod is drawn, the ball allows water to pass in, but it must be expelled through a small tube placed alongside, as the ball fits and closes the nozzle when pressed from behind with water and the piston. By practice, a workman may spread the water with his finger, and direct its course at will to any position or part of the house. If this cannot be done readily, another perforated rose may be screwed on instead, which will separate the particles of water as they pass through it.
