a dark canvas cloth at the base of the trees and scrape 

 off the egg masses by means of a wire brush. Then col- 

 lect the egg masses from the canvas cover and burn 

 them. 



Q. When is the best time to plant my willow hedge 

 and poplar screen, also tulip and sweet gum? 



M. A. S., Harrisbttrg, Pa. 



A. Willows and poplars can best be planted in the early 

 spring. Tulip trees and sweet gum can be planted best 

 in spring. 



Q. When is the best time to set out evergreens? 



J. P. E., Baltimore, Md. 



A. Early spring is the best time, though the latter part 

 of August is almost equally good. 



Q. What shall I use to paint tree wounds ? 



A. L. L., Chicago, III. 



A. Use refined coal tar, and if too thick, thin it down 

 with creosote. 



Q. I am much interested in the article referring to 

 Common Sense Tree Labels in American Forestry. I 

 wish to learn if these enameled labels may be purchased 

 for private use and from whom. 



H. M., Boston, Mass. 



A. Such labels may be secured from E. George & Com- 

 pany, 194 Front St., New York City; Standard Sign Mfg. 

 Co., Pittsburg, Pa.; New York Stencil Works, 100 

 Nassau St., New York City ; and the Ingram Richardson 

 Co., 100 William St., New York City. 



ADVICE FOR DECEMBER 



1. Fertilize, with well-rotted manure, all the weaker 

 trees on the lawn and some of the shrubs that need 

 encouragement. Apply the manure either as a top dress- 

 ing or else dig in lightly with the soil. Apply to a radius 

 equal in distance to the spread of the branches. 



2. Insert bolts in trees that have a tendency to split. 

 Most splitting occurs in January and February, and some 

 species, like lindens and elms, have a greater tendency to 

 split in the crotches than other species. Do not resort to 

 bolting unless absolutely necessary, because a bolt gen- 

 erally detracts from the beauty of the tree. 



3. Cut down all the marked trees and burn the infested 

 wood. 



A'. Look over your spraying apparatus and tools and 

 make all necessary repairs in preparation for the spring 

 season. 



NOTES 



Many authorities believe that filling tree cavities with 

 concrete is wrong, that such fillings are not permanent, 

 that the concrete cannot be waterproofed and soon cracks 

 and leaves a worse condition than no filler. 



C. H. Hoyt, of Cleveland, O., writes that he has been 

 several years perfecting a method of using the asphalt 

 method and has solved the problem by making it easy 

 to use and getting perfect protection at very small cost. 



He has recently issued an illustrated folder on this 

 method, which can be had for the asking. 



On October 1, 1915, all the Boy Scouts of Mount 

 Vernon, N. Y., assembled at the Presbyterian Church 

 and heard a detailed account of the life history of the 

 Tussock Moth, one of our worst shade tree leaf feeders. 

 This insect overwinters in the egg stage and from fall 

 till spring the eggs may be found in small white clusters 

 firmly attached to the bark of trees and protected places 

 along fence rails and under the house mouldings. Each 

 troop was assigned a definite section of the city and 

 each section was further subdivided for the individual 

 Scouts, so that the entire city might be covered. For 

 nearly three weeks the boys scouted around gathering 

 the egg masses and then the territory of each troop 

 was shifted so that the work might be checked up, triple 

 credit being given for eggs collected during this checking 

 period. Upwards of a quarter of a million eggs were 

 collected by the scouts during the contest, and it would 

 be difficult to state in dollars and cents the value of serv- 

 ice so rendered to the city. 



FOREST ITEMS FROM HAWAn 



A FOREST and grass fire late in August burned 

 over several hundred acres on the U. S. Military 

 Reservation on the Island of Oahu, Territory of 

 Hawaii, before it could be completely extinguished by 

 2,500 regular troops from Schofield Barracks who fought 

 it with difficulty on the steep mountain slopes with wet 



bags. 



In the work of reforesting with indigenous trees the 

 open areas on the watershed back of the city of Hono- 

 lulu, which was begun two years ago, the Division of 

 Forestry of the Territory of Hawaii uses imperfect cans 

 which are discarded by the hundred at the pineapple 

 canneries and may be obtained free of cost. One seed- 

 ling is raised in each can which first is split up the side 

 and the bottom almost completely cut around. The can 

 is held together with a wire. At the planting area, the 

 wire is removed, the can opened up and the seedling 

 taken out with a complete ball of earth around the roots. 

 Superintendent of Forestry C. S. Tudd reports that by 

 this method almost perfect success is obtained from 

 the planting. The cans can be used three or four times 

 for this purpose. 



The old royal Hawaiian palace in Honolulu, now used 

 for the executive offices of the Territory, is receiving a 

 new flooring of native ohia wood. This is logged and 

 manufactured at Pahoa, Hawaii, by the Hawaii Hard- 

 wood Company, which operates the only sawmill in the 

 Islands. 



During 1914, a little short of one million trees were 

 l)lanted in different parts of the Hawaiian Islands for 

 ornament, windbreaks, and fuel. Species of the Austra- 

 lian eucalyptus are used for the latter purpose and grow 

 so rapidly that they can be cut six years after planting. 

 Many of the species sprout readily from the stump.
