Referring to insects which crawl up or down the trunks of trees, Mr. J. W. Manning tells the Mass. Horticultural Society: "For tall elm trees, which cannot be reached with a syringe, printer's ink on a band of paper round the trees, or a metallic collar filled with oil, may be used. A box set round the base of the tree, with a trough for oil, was used in Mr. Clapp's orchard, in Dorchester, nearly forty-five years ago. The first set of boxes lasted twenty years, the second set still remain. They cost about two shillings each. The use of these methods would be of more benefit if a general application should be made to all the trees infested. It is a singular fact that the canker worm will eat everything up to a certain division wall, while beyond the wall not one will be seen. The orchard of T. C. Thurlow, West Newbury, was devastated for years by the canker worm, but the use of printer's ink, at the expense of four and a half cents per tree, was followed by a crop of nine hundred barrels of No. 1 Baldwins, seven hundred the next year, and fourteen hundred barrels the third year."
