The only species showing no signs of feeding were tulip, 9, and sassa-fras, one. A second count was made in a swampy area several hundred yardsfrom the first plot. The number of trees totalled 104, and the predomi-nant species here were red maple, 68, and American elm, 26. Other speciesincluded yellow birch, 3; shadbush, 2; butternut, 4; and winterberry,one. All of the trees in this general area were completely defoliated. An Outbreak of the Elm Spanworm in Connecticut 101. Figure 13. Trunk of tree, showing long skeins of matted leaf fragments. 102 Connecticut Experiment Station Bulletin 428 It appears, then, that swamp lands containing a large percentage ofred maple are particularly susceptible to attack by the elm spanwormwhen an outbreak occurs. The area previously mentioned at Middleboro,Mass., was of this type and was composed chiefly of white cedar and redmaple, with a lesser amount of yellow birch. The red maple suffereddefoliation of 90 to 100 percent; and birch, 60 to 65 percent. Completestripping for two or three successive seasons resulted in the death ofpractically all of the red maple. Although a close examination was notmade, most of the trees at Monroe were observed to have refoliated laterin the season. However, a number of elms along the border of a 50-acrepiece failed to put forth new leaves. SOME AFTER EFFECTS OF THE HURRICANE R. B. Friend A s AN aftermath of the hurrica
