No discoveries are of more importance than those which are connected with the improvement of agriculture. Every one who has attended to this subject is acquainted with the weeping destruction that has been occasioned by the genus of the Erica, or Caterpillar. Many counties of this kingdom, especially in the western districts depend in a great degree on the annual produce of the orchard : and in these districts, at least, it will be of great utility to circulate the intelligence of an experiment for the protection of fruit trees from the Caterpillar, which has been attended with complete success. A clod of earth is moulded round the top of the trunk of the tree ; and this is the whole process. From the hour that this operation is performed, the insects, even in the most remote ramifications, will begin to fall and the tree will, in a short time be wholly freed from this destructive incumbrance. It is true the animal will afterwards attempt to renew his depredations ; but as soon as he arrives at this ring of earth, which should be permitted to remain, he will hasten down the trunk with more rapidity than he attempted the ascent. We state this fact with confidence but we leave to the learned Zoologist the explanation of the mystery.
