the trunk carefully and especially the weak, wounded or decayed parts. 
He may find them in any of these portions of the tree. 
Appearance of the grub, and way of doing its work. The egg seems to 
be hatched hy the natural warmth of the season. The appearance of the 
grub is the following : — It is whitish in color, with a large head and body, 
whose diameter is about half that of the head, and whose length is about 
four times that of the head ; its general shape resembles that of a tadpole. 
We have seen them of different sizes, from half an inch to more than an inch 
long. Their ravages are committed in getting their food, which is the inner 
bark of the tree, and the tender wood. Sometimes they feed on the solid 
wood, especially in small trees. They are furnished with a strong pair of 
jaws, with which they eat their way along, leaving behind them a thin track 
of powder like sawdust ; they may be easily followed by these signs, when 
they confine their operations to the surface-wood. They may remain in the 
tree several years, before they emerge in the form of the beetle; for it is 
in the tree that they get their entire growth. In small trees they often 
penetrate to the very heart of the trunk, and seem to burrow there for the 
winter. We have dug them out of such hiding places, which they found in 
some beautiful Tallman Sweetings, that were utterly destroyed by them. 
Sow have they found their way to our orchards? They seem to follow 
the process of improvement, and to keep pace with the planting of trees 
and shrubbery of all kinds. They appear to go from the older portions of 
the country, to the more newly improved regions, making a few miles pro- 
gress every year ; we are inclined to think that they can spread quite 
rapidly, by the transportation of young trees from distant nurseries. 
Within a few weeks past, grubs have been taken from apple-trees which 
were taken from a Rochester nursery in the spring of 1854. These grubs 
were so large that the idea was at once suggested that they must be more 
than a year old ; this became almost certain, when these huge grubs were 
compared with some others, taken from trees near by, which were very 
small, though found where they might have had a rapid growth. It be- 
hooves us to look well to the trees we buy ; we do not know certainly, that 
nurserymen can detect the presence of the grub, in all cases ; but we think 
it can be ascertained whether the tree has been stung. If so, all buyers 
have the right to claim of sellers that no damaged articles be offered them. 
Sow shall we resist the Borer ? In all ways ; no one thing will do the 
whole work ; under the head of prevention, we would suggest several things : 
1. Buy none but sound trees ; sound, we mean, in every sense ; trees of 
vigorous growth, of fine roots, of unbroken bark, and that never have been 
stung by the beetle.
