yet to have data in regard to this experiment. During the spring 

 of 1911 a considerable number of additional tests will be made 

 and also there will be planted in some of the plots, seedling trees 

 of a number of species of Eucalypts. 



The amount allotted by the Forest Service for this project was 

 $2,000.00 for the fiscal year ending June 30, 1909. This was 

 mostly spent in fencing in a number of five-acre plots on each 

 of the two mountains. 



Last year $1,350.00 was allotted. This was used in the pur- 

 chase and transportation of nursery stock, for labor, and for the 

 enclosure of an additional plot on Mauna Kea. 



This year the amount is $1,000.00, which will be used mostly 

 for labor in planting out seedlings and seed. 



EUCALYPTUS STUDY. 



Also in cooperation with the Forest Service there was under- 

 taken, beginning late in 1909, a thorough investigation of the 

 planted groves of Eucalypts in Hawaii, with the object of com- 

 piling and making available for the ready use of those interested 

 all the information obtainable about the growth and yield under 

 local conditions of trees of this valuable genus. Under an agree- 

 ment whereby the Territory was to pay part of the cost of the 

 investigation and to publish the results, Mr. Louis Margolin, 

 Forest Examiner of the Forest Service, was temporarily detailed 

 to Hawaii from November 1909 to May 1910, inclusive. 

 During this time he visited all the Eucalyptus groves of impor- 

 tance in the Territory, made measurements and collected all the 

 available data in regard thereto. The material so gathered he 

 worked up in a report that is shortly to be published as Bulletin 

 No. 1 of the Division of Forestry. 



The appearance of this bulletin during the summer of 1910, 

 as was expected, was prevented by shortage of funds. When it 

 does come out, it should be of very considerable interest and real 

 value to all tree planters in Hawaii, because it contains just the 

 information needed by persons desiring to establish forest planta- 

 tions. Eucalypts are among the most important of our intro- 

 duced trees ; this report brings together in usable form all the 

 information now available about them under local conditions. 



BOTANICAL INVESTIGATIONS. 



A line of work of much interest during the past two years 

 is the botanical survey of the forests of the Territory now being 

 carried on by the Botanical Assistant of this Division, Mr. Joseph 

 F. Rock. As Mr. Rock clearly shows in the introductory para- 

 graphs of his own report, a study of this character is essential 

 to a correct understanding of our forests. Without exact knowl-
