averaging from five to six and one half feet in a season. They 

 are large enough to cut the second year, but produce only about 

 two tons per acre, and may continue to yield good crops for from 

 ten to fifteen years. By November the willow-whips are ready 

 to cut, the old stubs being left to produce the next year's crop. 



It is the object of the grower to produce a tall, straight but 

 flexible growth about one-eighth of an inch in diameter at base, 

 and measuring from five tD nine feet in height. The injury 

 caused by the beetles is not so much the weakening of the plant 

 by loss of foliage as by the branching of the willow-whips which 

 results from the injury to the rapidly growing tips. The beetles 

 which have lived over winter are astir early in May and feed for 

 two or three weeks. They attack the young willows vigorously, 

 feeding largely on the new growth, thus causing the tips to wilt 

 and die. Frequently the entire tip is eaten off. In this manner 

 irreparable injury is caused at the beginning of the season. 

 Plate I is from a photograph showing a bunch of young willows 

 with injured tips. Plate II is from a photograph of a normal 

 willow whip and one which was injured early in the season in a 

 manner similar to those shown at Plate I. A.t a the willow was 

 eaten off or sufiSciently to stop the growth, thus resulting in the 

 sprouts and consequent worthless willows as these sprouts never 

 become long enough for basket-making purposes. The uninjured 

 willow is shown on the left. 



The injurious work begun by the beetles is continued by the 

 larvse and adults of the next brood, and as these are much more 

 numerous and appear at a time when the willows are growing at 

 their best, the injury is much greater.
