REPORT OF ASSISTANT SUPERINTENDENT OP FORESTRY, 

 OCTOBER, 1921. 



November Dtli, 1921. 

 Superintendent of Forestry, 



Honolulu, H. T. 

 Dear Sir: 



T respectfully submit the following routine statement of my work dur- 

 ing October, 1921. 



MOKULEIA FOEEST EESEEVE. 



On October 3, in company with the Superintendent of Forestry and 

 Eanger Ellis, I visited the region of Kawaihapai in the Mokuleia Forest 

 Eeserve in order to flag the niakai boundary and to determine the amount 

 of fencing required to exelud? stock from this reserve. Professor Gregory, 

 of the Bishop Museum, accompanied us on the trip in pursuance of his 

 continuous study of the geology of the Islands. 



This semi-xerophytic ' ' transition ' ' forest, in which is found a more 

 variegated arborescent flora than in any other Haw'aiian forest type, has 

 been exposed to grazing cattle for many years, and the continued recession 

 of the forest makes its protection against stock an urgent matter. Hun- 

 dreds of acres are already possessed, to the exclusion of everything else, by 

 a thick growth of Avorthless lantana Avhich flourishes everyw^here in this 

 region where the native ground cover has been destroyed. Steep slopes 

 are eroded and deeply cut by innumerable cattle trails; in many places the 

 sterile bed-rock is exposed by landslides which had their origin in such 

 trails. Springs that were constant a few years ago are now permanently 

 dry ; streambeds Avhich anciently held torrents, and even in later years regu- 

 larly trickled small streams, have now been dry for several years. The 

 entire region demonstrates the havoc that can be wrought l>y cattle in 

 destroying this transition type of forest. 



MAUI COUNTY FAIE. 



Approximately two weeks Avere spent in connection with the exhibit 

 of the Board of Agriculture and Forestry at the Maui County Fair, held 

 at Kahului on October 13, 14, 15. This exhibit, representing the acitivities 

 of each Division of the Board, was considerably larger than the one of last 

 year and proved highly attractive as well as instructive to the visiting 

 crowds. In the Forestry section the rainfall-erosion ''model was again 

 shown, a large pyramidal table exhibited more than fifty varieties of trees 

 and plants and carried a diagrammatic poster explaining ' ' How Trees 

 Grow. ' ' Among the innovations were a very complete collection of tree 

 seeds arranged by Mr. Haughs, a set of thirty photographic enlargements 

 with explanatory legends giving a thorough exposition of ' ' Forestry in Ha- 

 waii,'' a collection of plain and polished boards of the more important 

 native and introduced woods cut from trees grown in Hawaii, and a novel 

 collection of fresh boughs of pine, spruce, and cedar brought down from 

 trees now- growing in the federal experimental plots on Haleakala. Little 

 blocks of true sandalwood, cut from trees in the forests of Oahu, and hun- 

 dreds of packages of ornamental tree seeds were given to visitors at the 

 Forestry exhibit. Large quantities of publications of the U. S. Department 

 of Agriculture were also distributed. 



FEDEEAL TEEE-PLOTS ON HALEAKALA. 



During my stay on Maui I made a thorough examination of the ex- 

 perimental plots of coniferous trees planted on Haleakala in 1909 and 1910 

 by the Division of Forestry in co-operation' with the I". S. Forest Service.
