trespass will be observed, and the amount and location of fencing re- 

 quired to stop such trespass. It is hoped that this entire makai boun- 

 dary can be surveyed and properly monumented during next summer, 

 so that the problem of cattle trespass can be more effectively dealt with. 



Up to November 30th the boundary had been examined across the 

 lands of Piihonua, Waiau, Puueo, Alae, and the Kaiwiki II homesteads. 

 The area mauka of the Kaupakuea and Honomu homesteads, and the 

 south half of the Kaiwiki III homesteads, were also examined. In a 

 remote clearing in the forest in Lot 67 of the Kaiwiki II tract, a Portu- 

 guese family containing nine small children was found living in a con- 

 ilition of insanitation which ought not to be permitted on any Govern- 

 ment homestead. 



A more detailed statement of the boundary examination will be sub- 

 mitted upon completion of the work. 



Eespeetfully submitted,

Assistant Superintendent of Forestry. 



REPORT OF THE ASSISTANT SUPERINTENDENT OF FORESTRY, 



DECEMBER, 1920. 



Honolulu, January 4, 1921. 



Mr. C. S. Judd, Superintendent of Forestry, Honolulu, T. H. 



Dear Sir: — The following routine report of my work done during the 

 month of December, 1920, is respectfully submitted: 



During the first twenty days of the month I continued and completed 

 the inspection of the makai boundary of the Hilo Forest Eeserve, on the 

 Island of Hawaii. Tliis work, although considerably retarded by bad 

 weather, was greatly facilitated by the generous cooperation of the 

 plantation managers in supplying saddle horses and guides familiar with 

 the difficult border country between the forest and the cane fields. 



On December 10, in company -with the President of the Board of Agri- 

 culture and Forestry and various public officials of Hilo, a visit was 

 made to the Wailoa River Park tract, which it is proposed to place 

 under the jurisdiction of the Board for development by the Division of 

 Forestry as an arboretum. Later I made a more intensive examination 

 of this area to determine its suitability for arboretum purposes. The 

 results of this examination are set forth in a separate memorandum. 



On December 11, in company with Mr, Atkinson and Ranger Mac- 

 Kenzie, I visited the Olaa Eanger Station on the A^oleano road. The 

 building is now complete, but requires some further additions of furni- 

 ture and utensils to be ready for occupancy. 



While in Hilo I visited the office of Doty & Co., manufacturers of 

 tree-fern starch. This company is at present getting its supply of fern 

 logs from homestead lands and has under way negotiations for the ferns 

 on a considerable tract of other private land which will supply its plant 

 for a long time. In collaboration with the U. S. Experiment Station, 

 experiments will be started in growing tree-ferns from the unused tops 

 of the trees in order to assure a future supply from private lauds. From 

 our present knowledge of the importance of tree-ferns in the economy of 

 our native forests, it does not appear expedient ever to permit the cut- 

 ting of thse ferns within the forest reserves. 



On December 21, I returned to Honolulu, where several days were spent 

 on office work relating to the Hilo Reserve project. Two short field trips 

 were made with the Superintendent of Forestry, one to inspect the co- 

 operative tree-planting within the Pupukea Forest Reserve, and the 

 other to examine the exotic tree plantations in upper Manoa Valley.
