THE BLACK HILLS BEETLE. 9 



Lake and at such other points as might be deemed necessary; to give 

 instructions to the forest officials and others in carrying out our rec- 

 ommendations for the control of this and other insects directly 

 associated with the dying timber, and to determine for the Forest 

 Service the approximate extent of necessary cutting of timber on the 

 reserve to protect the remaining living timber in the vicinity of Col- 

 orado Springs and adjoining private estates, as proposed by Gen. 



William J. Palmer.

 City, Bear Creek Canyon, High Line road, to Bruin Inn, returning by

Additional explorations were made on the r2th and 13th by Mr. 

 Edmonston, under my instructions, in the vicinity of Palmer Lake. 



During all but one of these trips I was accompanied by Mr. W. D. 

 Edmonston, head ranger of the Pikes Peak Forest Reserve, who was 

 designated by Forest Supervisor Clarke as the proper official to 

 receive instructions in the identification of the infested trees to be 

 felled and barked to kill the principal insect enemies. I was also 

 accompanied on a number of the trips by General Palmer's foreman, 

 who received similar instructions. Supervisor Clarke accompanied 

 us on two trips. General Palmer on three, and Forest Assistant 

 Clement on two. 



SUMMARY OF RESULTS, CONCLUSIONS AND RECOMMENDATIONS. 



(1) The depredations by the Black Hills beetle (Dendroctonus 

 ponderossB Hopk.) within the area examined are by no means as 

 extensive as we were led to believe from the reports and correspond- 

 ence.
