EASTERN HEMLOCK BORER 
Examination of the' root systems of 30 hemlock trocs in stands on the 
Menominee Indian Reservation, washed out in 1939 and 1940, has conclusively 
shown that the eastern hemlock borer ( Melanophila, fulvogutta.ta Harr.) can 
successfully attack eastern hemlock only when the trees are definitely dying 
from other causes. Therefore this borer should be considered as ?. secondary 
insect. The succession of consecutive drought vears in this region from 1930 
to 1937 was the primary cause of the heavy hemlock mortality in these . stands. 
There was a. noticeable reduction in the abundance of the beetles in 19^0 for 
the first time since the study was started in 1937* This is apparently be-
