The Cyclone Burner. 



The most effectual means of dealing with the pest in lands 

 which have grown up to brush is to cut the brush with axes 

 or scythes, sprinkle wdth oil, and burn brush, leaves and all 

 vegetation. In this work the spraying pump is very useful. 

 A portable tank is used, and a short hose terminated by a 

 hollow pipe twelve feet long is attached to the pump. A 

 Riley or Cyclone nozzle is used on the end of this tube, and 

 crude petroleum is pumped through this from the tank. 

 The fine spray of oil thus thrown is easily ignited, and 

 makes a very hot volume of flame which may be run over 

 the surface of the ground at will. Such an apparatus can 

 be handled by two men, and would probably be useful in 

 checking tlie invasion of such pests as the army worm. It 

 was by the use of this machine that we checked the ravages 

 of the moth in Swampscott, where all other means had 

 failed. On level ground an apparatus having several nozzles 

 could be mounted upon a wagon, and acres could be rapidly 

 burned over in this w^ay. In brush and on rough ground 

 the oil was s})rayed from a watering pot and burned after- 

 ward. 



It must be evident to all that an intimate acquaintance 

 with the territory infested, a study of the means of distribu- 

 tion and a knowledge of the habits and life-history of the 

 moth, its parasites and enemies, are all indispensable pre- 

 requisites to an intelligent effort for its destruction. In the 

 past two seasons we have tried to ol>serve and record all 

 facts bearing upon these subjects, and to obtain by com- 

 parison and deduction that exact knowledge which must be 

 our guide ; and yet there are some questions of vital impor- 

 tance which it will require the experience of another season 

 to answer, and the committee is not yet ready to make a full 

 report on the habits of the moth, its enemies and })arasites. 

 For such information as has already been published in regard 

 to the work I refer you to the special rei)ort of this Board, 

 which was made to the Legislature in 1892 and was |)ublished 

 in the last amnial report of the State Board of Agriculture ; 

 to a special bulletin published by the Hatch Experiment Sta- 

 tion, at Amherst, in November, 1881), written by Prof. C. H.
