mittee, and which is now being manufactured in a limited 

 way. This apparatus consists of a 100-gallon tank, mounted 

 on a suitable truck for transportation by hand, a powerful 

 double-acting brass pump with agitators, 200 feet of hose, 

 spray poles and nozzles complete, and can be purchased for 

 the lump sum of $125. The advantages of this outfit over 

 the one previously described are that it requires no team for 

 transportation, the pump is submerged and therefore there 

 is no leakage, while powerful agitators keep the mixture 

 thoroughly stirred. These outfits have been used in the 

 parks of Worcester and Springfield and elsewhere with com- 

 plete success. There is a question whether more and better 

 work cannot be done with two outfits of the kind previously 

 described, as used at Ipswich; but this is a point which 

 park authorities must settle after examining the respective 

 outfits. 



It may seem somewhat strange to pass the subject of 

 spraying outfits without extensive consideration of those 

 operated by power. The writer has carefully examined a 

 large number of these power outfits, secured figures of their 

 cost, etc., and has come to the conclusion that, at least for 

 our New England cities and towns, better and more satisfac- 

 tory work can be done with the same amount of money 

 invested in hand outfits. A suitable gasoline or steam spray- 

 ing outfit cannot be purchased for less than $225, the price 

 ranging upward to $500. A fair estimate of the cost of the 

 power apparatus would be $400, and for this sum there could 

 be obtained three outfits such as used in the gypsy moth 

 work, or seven like those used at Ipswich. 



The great desideratum in spraying operations is to thor- 

 oughly cover the infested territory in the shortest possible 

 time. This can be done by a battery of small outfits much 

 more satisfactorily than with power apparatus. These light 

 outfits permit simultaneous attack over the greater part of 

 an entire city , and with a suitable corps of men the spraying- 

 can be done at just the right entomological moment ; whereas 

 the same amount of capital invested in one or two power 

 outfits would not permit timely work on a large scale. In 

 addition, where such an outfit breaks down, everything
