April 25, 1882, and October 14, 1882 Observations nearly the same as in the preceding number, the bark under the cracked outer layer being all renewed, and with a bright, healthy, green layer free from stain; free growth of new wood during the season. 11. Concentrated lye, one pound; water, one and one-half gallons. Tree washed same time as above and with about the same results, al- though an unthrifty tree. October 14, 1882 The tree had been pretty well destroyed by the scale last year, and sh...ows but a little growth of new wood. 12. Concentrated lye, one lb. ; water, two gallons. Same as above, except that the tree was still more thoroughly ruined by scale, and at this date has not recovered ^but little new wood; what there is, however, being healthy. 13. Concentrated lye, one lt>:; water, three gallons. This tree had been washed by spray- ing April 1, 1881, with this strength of lye, which proved too weak to destroy the scale. July 23, 1881 Young scale insects covered the tree; the tree was left to itself with that wash- ing.
