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. 



EXPLORATIONS. 



Beginning on the morning of October 5 explorations were made as 

 follows: Glen Eyrie trail on mountain northward, returning via 

 Douglass Canyon; October 6, from Glen Eyrie by way of Colorado 

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

 way of North Cheyenne Canyon, Colorado Springs, and Palmer Park; 

 October 7, from Glen Eyrie by way of Manitou, over Crystal Park 

 trail to Crystal Park, returning by the Bear Creek trail, Bear Creek 

 Canyon, and Colorado Springs; October 8, from Glen Eyrie, by way 

 of Blair Athol, Pike View, Pope Ranch, and Palmer Park; Octo- 

 ber 9, from Colorado Springs by way of Colorado Springs and Cripple 

 Creek Railway to Clyde, thence by wagon to an altitude of about 

 10,000 feet, returning by same route to Colorado Springs; October 



10, from Colorado Springs by way of the Colorado Midland Rail- 

 road to Woodland Park, thence by wagon to Manitou Park; October 



11, by saddle from Manitou Park east to Palmer Lake, thence by 

 wagon southeast by way of Husted to W r oodland Ranch; October 



12, in the Colorado pinery on the Arkansas and Platte divide; Octo- 

 ber 13, in the Colorado pinery, returning by way of Colorado Springs 

 to Glen Eyrie. 



Additional explorations were made on the 12th 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 

 ponderosse Hopk.) within the area examined arc by no means as 

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

 ence.
