native forest by the cloudburst of January IG, when over 20 inches of rain 

 fell in 36 hours. Although the river bed was scoured out and kukui trees 

 uprooted in the valley bottom, the side gulches somewhat scoured, and a 

 few slides occurred on the palis, the condition of the remaining forest was 

 undisturbed, and if it had not been for this forest, there would have been 

 a m.uch greater flood in lower Palolo Valley and the Waikiki swamps. 



Assistance was rendered the Land Office in prescribing methods of thin- 

 ning and regulations to be inserted in the license for cutting algaroba 

 wood on public land in Lualualei, Oahu, to be sold at auction on Feb- 



ruary 25. 



Respectfully submitted,

REPORT OF THE ASSISTANT SUPERINTENDENT OF 

 FORESTRY, JANUARY, 1921. 



Honolulu, Hawaii, February 12, 1921. 



Superintendent of Forestry, Honolulu, T. H. 



Dear Sir: — The following report of ray activities during the month of 

 January, 1921, is respectfully submitted: 



The greater part of this month was spent in the Honolulu office ur)on 

 routine administrative matters. A memorandum was prepared concerning 

 the use of Wailoa River Park of Hilo as an arboretum; some time was 

 spent in transcribing data on the Hilo Forest Reserve and in the prepara- 

 tion of a bibliography of the genus Ficus. 



In company with the Superintendent, an inspection was made of the 

 Kuliouou Forest Reserve, Oahu, where a ridge-top fence was found com- 

 pletely undermined by wind erosion, permitting the entrance into the re- 

 serve of a number of cattle from the land of Maunalua east of the re- 

 serve. On this trip three wald goats w^ere found and killed on the divide 

 at the mauka edge of the forest. A number of trees of several species 

 were planted along the makai boundary to test their adaptability to this 

 site. 



A similar inspection of upper Palolo Valley disclosed considerabb dam- 

 age from the storms of the first two weeks of this month. Numerous land- 

 slides on the upper slopes and in the valley bottom, the erosion of the 

 trail and stream banks, uprooting of large trees, and the almost total dis- 

 truction of the eight-ineli water pipe line, the building of numerous gravel 

 banks to a depth of four and five feet by the flood waters, and the de- 

 struction of the water gate and 700 feet of forest fence, were among the 

 things that were observed. 



On January 22nd a conference, including Mr. Agee and Dr. Lyon of 

 the Planters' Experiment Station, the Superintendent of Forestry and 

 myself, was held to discuss the genus Ficus. It was decided to concm- 

 trate attention for the present upon the propagation of six species which 

 seem to give the most promise of being useful additions to the forests of 

 Hawaii and which appear unlikely to develop objectionable featuros. A 

 plan of cooperation between the Hawaiian Sugar Planters' Association and 

 the Territorial Division of Forestry for the administration of the Hilo 

 Forest Reserve was also outlined at this meeting. 



The latter part of the month was spent with Ranger Ellis and laborers 

 repairing the forest fences at Kuliouou and Palolo. 



Respectfully submitted, 



CHAS. J. KRAEBEL, 



Assistant Superintendent of Forestry.
