POSTS MADE DURABLE. 



Woods Given Sixteen Years' Addi- 

 tional Service by Preservative 

 Treatment. 



Fence posts of many kinds of cheap 

 woods which ordinarily would soon de- 

 cay if set in the ground can be made 

 to last for twenty years Ijy a simple 

 treatment with creosote. Most of the 

 so-called "inferior" woods are well 

 adapted to the treatment, and this is 

 especially true of cottonwood, aspen, 

 willow, syfcamore, low-grade pines, and 

 some of the gums. When properly 

 treated, these woods outlast untreated 

 cedar and oak, which are becoming too 

 scarce and too much in demand for 

 other uses to allow of their meeting 

 the demand for fence posts. 



Impregnation with cresote has been 

 greatly cheapened by the introdution 

 of the "open tank." which can be in- 

 stalled at a cost of from f30 to $15, or 

 much less if an old boiler is used. A 

 tank with a bottom 12 square feet in 

 area will suffice for treating 40 or 50 

 6-inch posts a day, or double this num- 

 ber when two runs per day can be 

 made. The absorption of creosote per 

 post is about as follows: Eucalyptus, 

 one-tenth gallon; willow, two-tenths 

 ffallpn; sassafras, ash, hickory, red oak, 

 ■Water oak, elm, maple, four-tenth's 

 gallon; Douglas fir, quaking aspen, and 

 black walnut, six-tenths gallon; syca- 

 more, cottonwood, and lodgepole pine, 

 seven-tenihs gallon. The price of 

 creosote is about 10 cents per gallon 

 in the East and Middle West, 16 cents 

 per gallon on the Pacific coast, and 27 

 cents per gallon in the Rocky Moun- 

 tain States. The cost of treating a 

 post will therefore vary from 4 to 

 15 cents. Properly treated, it should 

 give service for at least twenty years. 



Experiments of the Forest Service 

 show that with preservative treatment 

 the durability of lodgepole pine in Ida- 

 ho is increased sixteen years. The cost 

 of creosote is there relatively high, yet 

 by treating posts there Is a saving, 

 with interest at 6 per cent., of 2 cents 

 per post yearly. More important than 

 the saving, however, is the fact that 

 through preservative treatment other 

 woods are fitted to take the place of 

 cedar, of which the supply is rapidly 

 becoming exhausted. A detailed de- 

 scription of experiments in preservint; 



fence posts, together with practical 

 suggestions for treating them on a 

 commercial scale, are contained in 

 Circular 117 of the Forest Service. 

 This publication can be obtained upon 

 application to the Forester at Wash- 

 ington, — Press Review 27 (Circular 117 

 of the Forest Service).

The school ma'ams will flock to Am- 

 herst ngain next summer. The Massa- 

 chusetts Agricultural College will sup- 

 ply 'them with four weeks of fun and 

 study in the outdoor life. This plan 

 of teaching teachers out of doors was 

 tried with great success in the summer 

 of 1907, and the plan now is to give 

 more varied and extended exercises 

 along the same line. There will be 

 work in elementary agriculture, nature 

 study, science and education suited 

 for teachers, preachers and amateur 

 farmers. This is a novel departure 

 in school work, but one which is al- 

 ready giving good results.

 wait long enough, as Harry found out 

 to his cost. The uninsured are trot-
