Preserving Timber from Insects.

| Experiments made in France have shown that the reason the sap-wood in timber is worm-eaten is because of Ihe existence of starch in IL It is he starch that the insects are after, snd they do not attack the hard ivood because it contains no starch. The experimenters have devised a jnethod of preserving timber from such attacks. In the spring they cut i ring through the bark around the upper end of the trunk, and suppress all buds that are developed there. By autumn the starch has disappeared from the sap-wood and the tree is ready to be felled. Timber thus prepared, it is said, does not become worm-eaten.
