be used in place of arsenate of lead, but lime should be added to 

 prevent injury to the foliage. Arsenate of lead causes no injurj', 

 and adheres to the foliage for a long time. 



Caterpillars which are crawling about in great numbers on 

 trees, fences, etc., should of course be destroyed. Sprinkling 

 with kerosene, either pure or in an emulsion, or even with strong 

 soapsuds, is of considerable value in destroying them. 



Trees which are free from caterpillars may be kept so during 

 the season by applying a sticky band to prevent the caterpillars 

 from crawling up the trunk. Wherever the brown-tail moth 

 becomes abundant, it must of necessity be held in check chiefly 

 through the efforts of property owners in cooperation with 

 town or city authorities. The problem does not require the 

 same degree of care as is necessary in handling the gypsy moth, 

 and therefore it is not as essential that it be done by competent 

 men employed by the state.

 writer was accompanied by Mr. A. T. McCook, and the places

The Fresh Water Problem. 



Dodge Pond. A large fresh water pond situated a short 

 distance west of Niantic village. The pond is partially divided 

 into two sections. The small western section near the road is 

 covered with lily pads, and owing to the unusual season is dry 

 at this time. This drying up must have been gradu^, leaving
