20,799. Lack, C. T., and Chivers & Sons. Sept. 6. Animals, catching; adhesive traps.-A metal guard for protecting trees from insects &c. is provided with a strip d, Fig. 4, of ductile metal or material fastened round the large central aperture and adapted to be pressed into close contact with the tree, and to yield as the tree grows. The guard is coated with adhesive material, and consists of a disk a slit radially and secured on the tree by means of a metal disk c, Fig. 2, folded so as to embrace the overlapping ends. An indentation f is made in the disk e and guard a, thus forming a fastening which gives way when the tree becomes so large as to press against the disk a.
