experimental plnnting. This is an excellent opportunity for experi- 

 mentation in a thorough manner and on a scale which the Division of 

 Forestry is unable to practice independently. There is almost no limit 

 to the range of climatic conditions which can be found on, the Parker 

 Kanch, and Mr, Carter would be at pains to help tfs find the most favor- 

 able site for each species. The conifer plots established ten years ago 

 on the slopes of Mauna Kea are examples of the excellent results which 

 can be obtained by this sort of cooperation. 



At the time of our visit there were some 300,000 transplants in the 

 ranch nursery, including the genera Eucalyptus, Acacia, Araucaria, Cu- 

 pressus and Pinus. It is obvious that such vigorous efforts in forestry 

 deserve our most hearty support. 



MAUNA KEA EXPEDITION. 



During the first week of the month I made the ascent of Mauna 

 Kea with a party of government officials and scientific men, including 

 the Chief of the U. 8. Geological Survey for Hawaii, the Territorial 

 Ivand Commissioner, the Director of the B. P. Bishop Museum, and the 

 Superintendent of Forestry. The purposes of the expedition were sev- 

 eral, centering chiefly about the problem of mapping the mountain, and 

 sbout the reported evidences of ancient glaciation above the elevation 

 of 11,000 feet, which was Professor Gregory's principal concern. Un- 

 mistakable evidences of glaciation were found and a plan for further 

 study was developed by Professor Gregory. 



MISCELLANEOUS. 



During the second week I visited the Kalapana region of Puna with 

 Mr. Ehrhorn and secured photographs of forest and dune conditions. 



In company with the Superintendent of Forestry, the Commissioner 

 of Public Lands, and the manager of the Hawaii Mill Company, I went 

 over the newly established forest reserve boundary across the land of 

 Piihonua in order to discuss on the ground the conditions of the pro- 

 posed new lease of cane lands which relate to the problem of forest 

 administration. During this trip a plan for the planting of open areas 

 in the forest reserve was developed. 



With the Superintendent of Forestry and Mr. Bryan, Forest Eanger 

 for the H. S. P. A., I spent two days inspecting the line of survey of 

 the Hilo Eeserve boundary across the lands of Waipunalei, Laupahoehoe, 

 Piha, Opea, Kamaee, Hakalau and Kaiwiki. 



Several days were spent with Mr. Bryan examining the area to be 

 included in the proposed Manowaialee Forest Eeserve above Ookala. 

 It appears that the forest in much of the area is irregular in density, 

 due to an old forest fire, and that some planting will have to be done 

 to restore the region to a proper density for water-conserving purposes. 

 Several discrepancies in the old suiveys were uncovered, and these were 

 brought to the attention of the surveyor for correction in the final work. 



PINE TEEES ON MAUNA KEA. 



During the fourth week of the month I cooperated with Dr. H. E. 

 Gregory of the Bishop Museum on a trip up the northwest slope of 

 Mauna Kea. Dr. Gregory's object was to secure further evidence of 

 glaciation on the mountain, while I went to inspect the conifer plots 

 established in February, 1910, by Mr. Hosmer. Both objects were very 

 gratifyingly realized. Abundant evidences of glaciation were found 

 and numerous photographs of striations, moraines and ice-distributed 

 boulders were obtained. 



The tree plot at the lowest elevation, 7J)00 feet, contained a total of 

 201 thrifty trees, ranging in size from 6 feet to 20 feet, and including the 

 following species: Pinus coulteri, Cedrus deodara, Lihocedrus decurrens 

 and Pinus jefreyi, named in order of their vigor of growth. At 9,000 feet
