AMERICAN FORESTRY

estry School, followed with a very timely 

 and practical address on the effect of 

 smoke on trees. 



Prof. E. P. Felt, New York State En- 

 tomologist, told in a practicajl mianner 

 what his abservations have been of the 

 use of oil sprays. J. F. Collins, United 

 States Department of .'\griculture, used 

 slides to illustrate his address on pruning 

 and cavity work as applied to shade trees. 



A discussion led by Dr. Geo. E. Stone, 

 of Amherst, Massachusetts, brought out 

 the poor work done by many poorly trained 

 ree workers. He was loud in bis praise 



: the tree wardens of Massachusetts, 

 many of whom fill the office without com- 

 I)ensation, and are proud of their guard- 

 ianship over the trees of their boroughs. 



Mr. F. A. Bartlett, of Connecticut, dem- 

 onstrated the modern way of treating trees 

 for decay. 



I>r. Felt again addressed the Institute 

 with an illustrated talk on "Some Common 

 Insect Pests of Shade Trees." Attention 

 was drawn to the vital need of efficient 

 spraying to control most of these enemies. 

 He also suggested the various municipali- 

 ties refrain from planting one or two va- 

 rieties of trees and advocated the planting 

 of several varieties, devoting certain 

 streets to certain species, if such a uni- 

 formity is desired. 



The Institute closed with a report by 

 Mr. W. O. Filley, secretary-treasurer of 

 the Board, on the work of that body. 



BONUS FOR PLANTING TREES 



In order to encourage reforestation in 

 Nova Scotia. Mr. Frank J. D. Barnjum, 

 of Annapolis Royal, N. S., is offering a 

 cash bonus of $2.00 per acre to the farmers 

 of Nova Scotia for every acre of spruce 

 or pine seedlings planted by them on their 

 farms the coming spring of 1922, no one 

 farmer to be paid a bonus on more than 

 100 acres, so as to distribute the plantings 

 as widely as possible over the Province. 

 Location and method of planting must be 

 approved by the Government Forester of 

 Nova Scotia, if one is appointed, otherwise 

 by Mr. Barnjum's forester, to insure sat- 

 isfactory results. 



DISTINGUISHING MAHOGANY AND 



WALNUT FROM RED GUM 

 TN the manufacture of furniture and cabi- 

 nets a great deal of red gum is used 

 as an imitation of mahogany or Circassian 

 walnut. When red gum is properly finished 

 it can be made to look so much like either 

 of these woods that only by very careful 

 observation can the true be distinguished 

 from the substitute. There is a very dis- 

 tinct difference, however, between red gum 

 and mahogany or walnut. This difference 

 lies in the size of the pores. 



In mahogany, Circassian walnut, and 

 black walnut, the pores are so large that 

 they can be seen very distinctly on a 

 smoothly-cut surface of the end grain. 



where they appear as minute openings 

 smaller than pin holes but visible without 

 magnification. On surfaced faces the 

 pores appear as fine grooves, running par- 

 allel with the grain. They are even visi- 

 ble through the varnish, appearing as dark 

 lines. 



In red gums the pores are much smaller 

 and can be seen only with a magnifying 

 glass. 



EVERY STATE USES WEST COAST 

 SHINGLES 



TF7ESTERN red cedar shingles from 

 " Oregon and Washington are shipped 

 to every State in the Union. Minnesota is 

 the largest single purchaser of Washing- 

 ton shingles, while California is the biggest 

 buyer of Oregon shingles. The Middle 

 Western States are very heavy buyers 

 while about eight per cent of the total sales 

 go to the Southern States. 



Oregon and Washington produced six 

 and one-half billion shingles in 1919, or 

 two billion more than in 1918. The cut 

 for 1919 was less than that for 1916 or 1917, 

 and far below that for 1909. 



Western red cedar is the leading shingle 

 wood in the United States. Shingles manu- 

 factured from the wood in Oregon, Wash- 

 ington and British Columbia represent 85 

 per cent of the total production of the 

 country. Shingles are also made from 

 cypress, white cedar, redwood and yellow 

 pine. Douglas fir shingles were manufac- 

 tured commercially in 1919, largely because 

 of the scarcity and high cost of western red 

 cedar logs.
