FORESTRY IN COLORADO 9 



(d) The posts employed in the demonstrations may be such 

 as are available cottonwood, poplar, aspen, lodgepole pine, Doug- 

 las fir, or other cheap woods, if possible. They should be round in 

 form, free from bark and seasoned for at least five weeks. 



(e) Illustrative material showing how and where a post de- 

 cays and the effect of the preservative should be exhibited. A 

 fence post nearly rotted off and shown in lengthwise sections to- 

 gether with one that has been treated, may be used. 



(f) Brush treatment of posts should also be demonstrated. 

 The outfit may consist of a wire-bound roofing brush, a galvanized 

 iron bucket and a suitable trough for holding the post and catching 

 the excess creosote during application. Hot creosote should be 

 painted upon the butt end of the post to a height of 30 inches and 

 after this has penetrated, a second coat is to be applied. 



The top end of each post should be cut sloping and creosote 

 applied in both processes of treating. 



During the autumn of 1914, Mr. J. R. Wheeler was put in 

 charge of this work. His report in part is as follows : 



"The following towns were visited during agricultural fairs : 

 Loveland, Greeley, Grange Hall, Pueblo, Montrose and Kremmling. 



"A banner was displayed reading as follows: 



" 'Farm Forestry Demonstration in Timber Preservation 



" 'Under Direction of The State Forester, 

 " 'State Agricultural College, Fort Collins, Colorado/ 



"Cheap, quick-growing timber, such as cottonwood and poplar, 

 can be made to last 15 or 20 years. Lodgepole pine, Engelmann 

 spruce, and balsam fir can be made to last equally well in this way. 



"Comparative cost of Lodgepole pine in Idaho : 



First cost of post .06 .06 



Cost of treatment .00 .15 



Cost of setting post .12 .12 



Total cost of set post .18 .33 



Estimated length of service 4 years 20 years 



'Annual cost of post, approximately 



(allowing 6% on investment) ___ .05 .03 



Annual saving per post .00 .02 



"The object of the demonstration, to show people how to make 

 use of their cheap, home-grown timber, such as cottonwood and 

 willow, was somewhat thwarted in my not being able to get this 

 kind of timber to demonstrate with. 



"In some instances split cedar was used. This post proves to 

 be a very poor one according to the experience of many farmers,
