edge concerning the habits of the trees and other plants found 

 therein, plans for the proper care of the forest can not be as 

 wisely made as when these data are available. The investigations 

 being carried on by Mr. Rock deal in many cases with questions 

 of pure science, but they all have their practical bearing in one 

 way or another. 



In his report along with an outline of the work done on his 

 collecting trips, Mr. Rock records many interesting facts about 

 the vegetation of certain little explored localities. It contains in 

 this way much of interest from a geographical as well as from a 

 botanical standpoint. 



The importance of the results already got in this investigation 

 justify better provision being made for it in the future. Not only 

 are additional herbarium cases needed for taking care of the 

 material collected, so that it will be protected from insects and 

 housed in a manner where it will be readily available, but pro- 

 vision should also be made for the publication of results. This, 

 as Mr. Rock points out, is an essential part of this sort of study. 



Although somewhat out of place here, it might be said in this 

 connection that the Board of Agriculture and Forestry has for 

 some time had the manuscript of two bulletins ready for printing, 

 the publication of which has been prevented by lack of funds. 

 One is a popular treatise on "The Vegetable Garden in Hawaii," 

 by Professor F. G. Krauss, which contains just such information 

 about gardening methods as people are constantly asking for. 

 The other is a compilation of the laws concerning, and the rules 

 and regulations made by the Board of Agriculture and Forestry. 

 Both are useful books, that ought to be published. 



MISCELLANEOUS FOREST WORK. 



The activities of the Division of Forestry are not confined 

 strictly to the work described under the heads Forest Reserves 

 and Forest Extension. Other branches of forest work are pur- 

 sued as fast and as far as time and resources permit. 



RUBBER INVESTIGATION. 



As entitled, chronologically at any rate, to first mention, is the 

 successful outcome of the investigation on methods of tapping 

 rubber trees, carried on jointly by this Division and the Hawaii 

 Agricultural Experiment Station during the spring of 1909. It 

 will be remembered that out of its allotment for the fiscal period 

 ending June 30, 1909, the Division of Forestry contributed 

 $1200.00 toward this study the Experiment Station providing 

 the men to do the necessary work in field and laboratory. This 

 investigation proved that with systematic methods of tapping the 

 Ceara rubber tree in Hawaii will yield profitable returns, a fact
