Fruit on an unsprayed apple tree. ing is indicated by the difference in the market value of cider stock and high-grade packing stock. APPARATUS. The spraying equipment should be consistent with the size of the orchard and whether it consists of a hand pump or a power machine, all working parts that come in contact with the spray mixture, such as the pump plunger, pump packing, pump valves and cut-offs should be kept clean and occasionally oiled to prevent corroding from the liquid and thus interfering with their operation. Leaks should not be tolerated in any part of the equipment. If a power machine is used it should be supplied with two sets of nozzles; one set of the Bordeaux type, the other set of the disc type. Bordeaux noz- zles, which make a coarse spray, are of value chiefly in making the first spraying for codling.
