SHADE AND TIMBER TREE SURVEY OF COLORADO 

 STATE FORESTRY PROJECT NO. 2 



Work upon this project has been greatly hampered for the 

 same reasons mentioned in connection with Project No. I, and 

 practically no progress has been made except to complete the shade 

 tree survey of the city of Fort Collins, which was begun during the 

 first biennial period. It is particularly desirable that this project 

 should be carried on for the reason that some of the oldest timber 

 plantations in the state are being cut and worked up into lumber, 

 fuel and posts, and the data which these plantations offer should 

 be secured and recorded. 



STATE FORESTRY PROJECT NO. 3 



NAME OP PROJECT. Demonstrations in Timber Preservation. 



OBJECT. To teach fanners and other interested persons how 

 to prolong the period of use of fence posts by preservative treat- 

 ment. 



LOCATION. The work to be carried on at the State and County 

 Fairs and similar gatherings throughout the principal farming sec- 

 tions of the State. 



METHOD OF PROCEDURE. The person in charge of this work 

 shall visit such fairs or similar gatherings of farmers and persons 

 directly interested in agriculture as the time will permit and show 

 by actual operation the process of fence post preservation adapted 

 to the ordinary farm. 



(a) For this work a suitable portable outfit shall be obtained 

 which can be shipped to the places of demonstration and quickly 

 set up and put into operation. This outfit should consist of a riveted 

 sheet iron tank of one-eighth-inch black iron ; 30 inches in diameter 

 and 44 inches in height, and a sheet iron fire box with smoke pipe 

 for the heating of same. A chemical thermometer registering to 

 250 degrees Fahrenheit should be used in regulating 1 the tempera- 

 ture of the preservative. 



(b) The preservative used may be one of the standard gas 

 tar creosotes or any of the local gas tars or gas tar products most 

 readily and cheaply obtainable. 



(c) The process employed shall be the open tank process as 

 described in Farmers' Bulletin No. 382 of the United States Depart- 

 ment of Agriculture, title : "The Preservative Treatment of Farm 

 Timbers."
