There should be a cut-off at the lower end of the ex- tension rod, and it should have a handle of sufficient size to give a good grasp for turning on or off. Unless rods are provided with an easily operated cut-off, much spray material wiU be wasted in working from one part of a tree to another or from tree to Fig. 66. -Cut-off and end of bamboo exten- sion rod. Original. Hose Hose leads are essential for barrel or power outfits. The length of hose naturally \-aries with the character of work contemplated. If two leads are used from a single [tump, and one operator stands on the spray wagon or on an ele\-ated platform, it is convenient to have the hose in two lengths, the longer for the man on the ground and the shorter for the man on the platform. One half or tliree eighths inch hose may be used. The former transmits the pressure to better advantage; the latter is hghter to handle. Hose connections deserve consideration, especially in outfits designed to work under considerable pressure, as in power apparatus. The long connections, wliich admit of two bands on each side instead of one, should be selected. In high-power outfits for shade-tree work, special hose is needed. Connections are obtainable for this work which are pro\'ided with bands fastened mechanically to the unions, so that the hose cannot come apart when being dragged over the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability -
