The double-edged pruning saw with coarse teeth on one side and fine on the other would be far more widely used, if it were not for the fact that the unused edge so often injures the bark of the trunk when the saw is being used. A very satisfactory guard may be quickly made of a brass curtain rod by prying it apart slightly at the seam and cutting: a suitable lensrth to fit over the edge, as shown in the sketch. This will cling to the saw blade by its own tension. - Contributed by James H. Brundage, Katonah, N. Y.
