Double and Triple Jets.—These are not economical in any way, and so much wash is wasted either through the nozzles being set wrongly and causing a crossing of the cones, or through too great an area being covered in the case of jets which issue at a wide angle. A Medium-sized Cone fitted with self- cleaning pin is required for lead arsenate and other stomach poisons; a penetrating and concentrated jet for contact washes, and a fine, mist-like spray for applying fungicides. Aphis Nozzles.—This class should give a penetrating spray, and the nozzle should required (it need not be adjustable); the make of nozzle best suited is one that is cleared simply by tapping the end of the nozzle against the trunk or a branch, when the ejector pin will clear the obstruction. Angle Bends.—If the nozzles are not swivel-mounted, one must have an angle bend attachment to fit the nozzles on, for without this adjuster the under surface of leaves cannot be successfully sprayed.
