prevent, as far as possible, the transportation of the pests and their 

 propagation in new localities. If insects suspected of being the 

 brown-tail or gypsy moths are found within the borders of Rhode 

 Island, notice should at once be sent to the Commissioner for Sup- 

 pressing the Gypsy and Brown-tail Moths, at Kingston. 



REMEDIES. 



If the brown-tail moth is found when it first gets into any region, 

 it may be readily destroyed. The winter nests are easily seen when 

 the leaves are off the trees, and if these are cut off and burned there 

 will be no further trouble from the insect. For this work it is neces- 

 sary to get what gardeners call the " pole pruner " which is a pair of 

 pruning shears at the end of a long pole. (Fig. 3, Plate III). The cater- 

 pillars are also readily destroyed by spraying the trees, in early sum- 

 mer or after the caterpillars have hatched in the fall, with Paris green 

 or lead arsenate. The foliage must be thoroughly covered, and in 

 order to do this the spray should be applied, in the form of a fine mist, 

 by means of a good spray pump and especially designed spray nozzle.
