 MISCELLANEOUS. 



Before leaving- Hawaii I collected a quantity of seed of the Kopiko 

 (Straussia hillebrandii) which was fruiting abundantly along the Vol- 

 cano Highway at six miles. I also shipped to t)ie central nursery at 

 Honolulu twenty-five bags of tree moss w^hich was collected by a home- 

 steader's family in Kaiw'iki. 



On .September 18th I returned to Honolulu on the Matsonia, and 

 the remainder of the month was given largely to the preparation 

 of a forestry exhibit for the Mani County Fair to be held October 13, 

 14, 15. 



Two days, however, werd spent with the Superintendent of Forestry 

 at Waiahole where a stwingingi water gate was constructed in the 

 forest boundary fence across Waiahole Stream. 



AIRPLANE SUEVEY CONFERENOE. 



On September 28 a conference was held in the office of Major Curry, 

 Air Service, at Fort Shaffer, to discuss the use of airplane photographs 

 in various scientific and' engineering activities of other government 

 departments. The conference included, besides Major Curry, A. O. 

 Buiikland, Cihief of the U. S. Geological Survey in Hawaii, Representa- 

 tive G. P. Wilder of the Territorial Legislature, the Superintendent 

 of Forestry and myself. The discussion revealed that mosaic photo- 

 graphs would be of great value to the Geological Survey in mapping 

 difficult areas; to the Bishop Museum in numerous researches and par- 

 ticularly in delineating the giaciation of Mauna Kea; and to the 

 Division of Forestry in surveying reserve boundaries, in studying the 

 interior condition of important reserves and the gradual recession of 

 their edges, in developing working splans for the planting of bare areas 

 within these reserves, in selecting the location of protection fences, in 

 deciding the limits of new forest reserv-es and in making changies in 

 existing boundaries. In fact, from the standpoint of forestry alone, 

 whatever expense would result to the Government in securing suc'h 

 airplane photographs would be more tlhan justified by the uses which 

 they would serve. Major Curry felt confident that^it was entirely 

 feasible to secure the desired photographs and that the work W'OulJ 

 be iweleomed with interest by the fliers(. Further arrangements will 

 have to be made, hovrever, inj seiCuiring official authoirization and 

 in getting adequate supplies of motor fuel before any work can be 

 undertaken. The effort will then be made to combine this photographic 

 work with the regular program of Air Service activities on the various 

 islands. InS'tead of being done as a seiparate project it will be accom- 

 plished gradually as opportunity offers. The results of this prelim- 

 inary conference iwere higjhly encouraging since it appears certain that 

 the cooperation of the Air Service wdll be forthcoming. 



Respectfully submitted, 



0HA8. J. KRAEBEL, 

 Asst. Superintendent of Forestry.
