PLAN FOR TREE EXHIBIT 



In its work of cooperating with the General Feder- 

 ation of Women's Clubs, this department of American 

 Forestry has prepared the following outline of a plan 

 for an exhibit in ornamental and shade tree work, to be 

 held in Xew York City in May, 1916: 



VALUE OF TREES 



1. Streets without trees and streets with trees 

 photos. 



2. A home with and without trees. 



3. Example of a tree providing shelter to mothers 

 and children. 



4. Specimen trees showing beauty of trees in all 

 seasons. 



PLANTING 



1. Photograph and transparencies showing specimen 

 trees of best varieties. 



2. Showing streets properly planted with suitable 

 trees. 



3. A model showing an ideal shade tree and methods 

 of planting. 



4. Chart showing detailed cost of planting a shade 

 tree. 



PRUNING 



1. Specimens showing proper pruning and results 

 of improper cutting and failure to cover wound with 

 coal tar. 



2. Photos showing trees and streets badly pruned and 

 improperly pruned. 



3. The best tools used in pruning trees. 



INSECT ERADICATION 



1. Cases illustrating, with actual specimens, the life 

 histories of some of the most important insect pests, as 

 the Tussock, Browntail and Gypsy moths, the Leopard 

 moth, etc. 



2. Model spraying apparatus from well-known makers. 

 ''>. Chemicals used in spraying. 



I. Photos showing spraying work in cities. 



0. What the children may do to help insect eradica- 

 tion. 



DISEASE ERADICATION

2. A treated wound. 



3. Collection of most important fungi. 



CITY FORESTS 



1. Photos showing the City Forests of the Country 

 and how they are being developed. 



2. Photos showing City Forests abroad. 



MUNICIPAL PARKS 



1. Pest park views. 



8. Utilization of parks by the people park recre- 

 ation. 



STATISTICS 



1 . Chart showing the number and appropriations of 

 shade tree commissions, Park Departments, etc. 



EDUCATIONAL 



1. Collection of city tree ordinances. 



2. Best books, magazines, pamphlets, etc. 



3. Circulars on Children's Tree Clubs, Arbor Day 

 Celebrations, etc. 



THE WOOD FLOUR INDUSTRY 



MORE than twenty thousand tons of wood flour, 

 valued at $300,000, are used annually in the 

 United States in two widely different industries, 

 the manufacture of dynamite and the manufacture of 

 inlaid linoleum. Wood flour is also used in making com- 

 position flooring, oatmeal paper, and in several other 

 industries. It forms one of the means by which the 

 huge waste product of our lumber mills is beginning to 

 find some better means of disposal than the burner. Since 

 a total of 36,000,000 cords of such waste is produced 

 each year at sawmills in the United States, of which 

 about one-half goes into the furnaces as fuel, while the 

 rest is burned as refuse to get rid of it, there is no lack 

 of raw material for industries which can develop ways 

 of turning this waste to account. 



Two methods of producing wood flour are practiced, 

 one using millstones, the other steel burr rollers to pul- 

 verize the wood. The latter requires only one-fourth 

 as much power to operate as the former and was devel- 

 oped on the Pacific Coast to handle sawdust as a raw 

 material. The mills of Norway which produce much 

 of the European wood flour are of the stone type. 



Wood flour mills are scattered over the country from 

 Maine to California wherever the proper combination 

 of wood and water power is available, and the domestic 

 wood flour competes with the Norwegian product which, 

 before the European war, was delivered at Atlantic ports 

 for $12.50 to $15 per ton. 



LARGE SALES OF NATIONAL FOREST TIMBER 



BIDS were recently accepted by the Department of 

 Agriculture for two large bodies of National For- 

 est timber estimated to contain 188,100,000 board 

 feet. One is in California and the other in Utah. With 

 one exception, these are by far the most important sales 

 made this fiscal year, which is expected by forestry offi- 

 cials to run considerably above last year in receipts from 

 timber sales, the first five months having shown an in- 

 crease of nearly 40 per cent. The California sale is 

 on the Plumas National Forest, in the Sierra Moun- 

 tains. The most valuable timber is sugar pine, for which 

 $3.25 per thousand was bid, with an estimated total 

 of nearly 26,000,000 board feet on the tract. For yellow 

 pine, of which the amount is put at over 37,000,000 feet, 

 $2.60 was bid. 



The Utah timber is in the Wasatch National Forest, 

 and will be cut chiefly for railroad ties. It comprises, 

 according to the Government's estimate, 82,100,000 board 

 feet of green and dead lodgepole pine, Engelmann spruce, 

 and Alpine fir. The sale price is 10 cents for each tie 

 cut and one-half cent per linear foot for mine timbers.
