No. 4.] THE ARMY WORM. 291 



it difficult to crawl up the vertical side of the furrow, and 

 crawling along it instead. About every 10 feet along the 

 furrow a small hole should be dug in which the caterpillars 

 collect, and where they can be destroyed by crushing or 

 pouring in kerosene or quicklime. A band an inch or more 

 deep of powdered lime (agricultural lime) has proved quite 

 an effective barrier in some cases this year, and in others 

 better results were obtained by plowing the furrow so as to 

 throw the earth out on the side away from the caterpillars. 

 In any case a furrow to be effective must be thoroughly dry. 

 The dust band so frequently recommended did not prove 

 satisfactory. 



Excellent results attended the use of a bran mash bait. 

 This was prepared by taking 1 pound of Paris green, 25 

 pounds of bran or middlings, 2 quarts of cheap molasses, 

 and water to make a thick mash when thoroughly stirred. 

 This was placed in strips across the line of march or spread 

 broadcast, and the caterpillars fed freely upon it. The 

 drawback to this method is that fowls and many birds feed 

 freely upon this mash and are also poisoned. This may 

 also happen if birds feed upon poisoned caterpillars. 



Sometimes the army worms crawl up on the stems of 

 grasses, grains, etc., and remain there feeding, so that 

 materials placed on the ground, such as bran mash, do not 

 reach them. In several instances two men with a rope 

 stretched between them, walking across fields where this 

 was the case, would knock off the caterpillars, which would 

 then feed upon the poisoned bait below. 



If cranberry bogs are menaced from the sides, filling the 

 ditches quite full of water should prove effective when this 

 is possible. If not, and the worms can enter the bog or 

 are already in it, spraying with arsenate of lead as already 

 directed is probably the best treatment. 



Enemies. 



There are many enemies of the army worm. Birds feed 



freely upon it, and during the present season the State 



Ornithologist, Mr. E. H. Forbush, has collected reports 



that the "birds seen to feed on the army worms here and
