Others are so constructed that the spray is discharged laterally or at a more or less acute angle (figs. 2 and 3). In using these nozzles for winter w^ork on deciduous trees it has been found that most thorough and most satisfactor}^ work can be done with less w^aste of spra}' when nozzles having a lateral discharge are emplo3^ed. The reasons for 1^^ ^^ skeleton or framework, presenting to the sprayer â 1% ^^s!^ ])^^ ^ limited surface for stopping a direct spray. For this reason, where a nozzle hav- ing a direct discharge is employed, a large portion of the spray Avill of necessity pass through the limbs of the tree and fall upon the ground, while at best it will pass through the tree but once. Bv using the cyclone nozzle with lateral discharge, h()we\'er, the cone of spray may be directed upward through the whole top, and in falling back it passes through the tree a second time. Here is a decided gain in the liml) surface which will be reached by the use of a given amount of spray. The nozzle having lateral discharge can also be handled to much greater advantage than the nozzle w ith direct discharge. By turning the extension pip(^. which bears the nozzle, the cone of spray may be directed upward, downward, or laterally upon the limbs as desired. This has proven of great advantage in doing thorough w^ork. The ordinary lateral discharge cA^clone nozzles are suitable for use with most of the copper sprays. For use with the sulphur sprays or Bordeaux mixture containing a large amount of lime, the common Vc^rmorel or cyclone* nozzle is rather too light and the opening too small. In California a special f
