agents and experts will be available for 

 demonstration work. 



In the meantime, every one who is inter- 

 ested in the protection of the pine timber 

 land, and the prevention of the widespread 

 destruction of the pine throughout the 

 country should report to this bureau the 

 location of every large patch of dying 

 or red-topped dead timber observed be- 

 tween now and the first of next February. 



The time to conduct the real work of 

 control will be between the 1st of Novem- 

 ber, 1911, and the 1st of March, 1912, and 

 concerted action in carrying out the most 

 eronomical and effective methods in the 

 affected areas in each county of the sev- 

 eral states involved is essential to success. 



The methods of control will vary some- 

 what in different localities and sections of 

 the region, but briefly they are as follows: 



a. The location of dying trees actually in- 



fested with the broods of the destructive 

 insects. 



b. The destruction of the broods in the 

 bark of the main trunks of the trees. This 

 is accomplished in many different ways, 

 and whenever the wood can be utilized for 

 cordwood, lumber, or other commercial pur- 

 poses, the value of the product will balance 

 the costs of treatment, and in some cases 

 yield a profit, but to avoid serious mistakes 

 one must know how and be sure he Is right 

 before he makes the attempt. 



The advice of the experts of the bureau 

 of entomology. United States Department 

 of Agriculture, can be had for the asking, 

 and personal instructions will be given and 

 demonstrations made in sections of the 

 several states where the greatest interest 

 is manifested and where the best facili- 

 ties are offered for rendering the service to 

 a large number of owners.
