17 orchardist then suddenly wakes to the fact that something is wrong, and upon close examination soon discovers that his trees are girdled. Mice are more prevalent in orchards under sod than where cultivation is practised, but even cultivated orchards are not free from their depredations, so young trees should be regularly protected against their ravages. This may be accomplished in two ways: (1) by the use of building paper, and (2) by the use of wire or metal protectors. The building paper is a very cheap means of protection from the standpoint of material, but, as it lasts only the one season, is extravagant of time through the necessity of wrapping the trees each fall. Single-ply white or grey building paper is used. Tar paper may be used, but

The paper is cut into strips about six or eight inches wide and the full length of the roll, which is generally about thirty inches. The paper is wrapped fairly snugly around the trunk of the tree and tied with binder twine top and bottom. After tying, a little earth is mounded up around the base to prevent rodents working under the paper. This paper is generally removed in the spring. (Fig. 11.) The other method, the use of wire or metal, is more permanent, more expensive in material, but cheaper in labour, for the metal protectors last for a long period of years. Fine meshed galvanized wire netting is the most lasting material. It is fastened by small pieces of wire, and is made large enough to allow for the trunk expanding as the tree grows. Another very satisfactory and cheaper material is made from expanded metal, such as is used in building. It is better when both galvanized and dipped in paint, in which state it may be obtained from the factory. This material is fastened around the trunk by small wire fasteners as is the wire netting. It is advisable to stick the ends of these wire protectors in the soil so that there will be no danger of the mice working from underneath. Poison Bait.—It frequently happens where there is a heavy fall of snow that the damage from rabbits is almost uncontrollable, as they are able to girdle and chew the branches by standing on top of the snow. The building paper and wire protectors are of little avail against such depredations. Unfor-
