diameter, a neighbor enquired if the borer was among his trees, 
saying it had killed nearly half the trees in his orchard. This 
was the first time his attention was directed to this insect, and on 
examination he found that almost every one of his trees had from 
one to five worms in them; and several were destroyed, beyond # 
all possibility of saving them. In one instance he has found 
twenty of these worms in one tree. For a few years past they 
have not been so numerous in his vicinity as they previously 
were. He has kept a pretty accurate account of his fruit trees, 
and finds that of all the apple trees he has planted, he has lost 
one in every eight from the borer. The insect is more fond of 
the quince, even, than it is of the apple, insomuch that he has 
found it impossible to grow this fruit, the stalks, notwithstanding 
all the care he has given them, being almost invariably riddled 
by the borer. Though he has set out very many quince trees 
during the past sixteen years, he has never been able to get but a 
dozen quinces, and these were gathered in the fall of 1853, when 
all kinds of fruit were so abundant in his section of country. 
The accounts which have been given, and the ideas that are 
prevalent respecting the burrow which this worm excavates in 
the trees which it attacks are very imperfect, and in part errone¬ 
ous. It is the common opinion that it simply bores a cylindrical 
passage upwards in the solid wood of the tree, which passage it 
keeps clean and empty. If this were the case, a constant effort, 
I think, would be required to prevent this footless worm from 
falling to the bottom of its burrow. As we shall see, that part 
of its operations whereby it-does the most injury to the tree, has 
been hitherto overlooked. 
The winged beetle makes its appearance every year early in 
June. Like other species of the family of long horned beetles 
(Cerambycida ) to which it pertains, it flies only by night. In the 
course of this and the following month the female deposits her 
eggs, one in a place, upon the bark, low down, at or very near 
the surface of the earth; but when these beetles are numerous, 
some of their eggs are placed higher up, particularly in the axils 
where the lower limbs proceed from the trunk. From each of 
these eggs is hatched a minute grub, or more properly a maggot,
