at the annual meeting of the Hawaiian Sugar Planters' Associa- 

 tion and a talk was given to the pupils of the Normal School on 

 Arbor Day of that year. A paper on Street Tree Planting read 

 before the Kilohana Art League was later published in more 

 extended form in Thrum's Annual for 1913. This paper con- 

 tains a list of trees suitable for use locally for this purpose, with 

 brief notes in regard to each species. 



There are increasing calls for a popular bulletin descriptive 

 of the common introduced trees planted in Honolulu. It is hoped 

 that such a publication can be prepared and issued by the Divi- 

 sion of Forestry. It would meet a real demand. 



BOTANICAL SURVEY. 



Until September, 1911, Mr. Joseph F. Rock was a regular mem- 

 ber of the staff of the Division of Forestry. He was then trans- 

 ferred to the faculty of the College of Hawaii. Mr. Rock con- 

 tinues, however, as an honorary officer of the Board with the title 

 "Consulting Botanist." 



Under a carefully worded agreement, the herbarium of the 

 Board of Agriculture and Forestry, with the cases in which it is 

 housed, has been loaned to the College of Hawaii. The collec- 

 tion was transferred to the College building in Manoa Valley in 

 the summer of 1912. It may there be consulted by those inter- 

 ested. 



In the spring, of 1911, Mr. Rock made collecting trips to Ha- 

 waii and Maui and that sumimer again visited the Kau District on 

 Hawaii. On each of these expeditions he collected much new 

 herbarium material which was added to the collection. Pend- 

 ing the completion of the new building of the College of Hawaii, 

 Mr; Rock continued to occupy quarters at the Board's office on 

 King street, until July, 1912. 



In September 1911 there was issued as Botanical Bulletin No. 

 I of the Division of Forestry, an illustrated 15 page pamphlet en- 

 titled "New and Noteworthy Hawaiian Plants." In December 

 1911 another similar bulletin was issued by the College of Ha- 

 waii describing some additional new species, under the title "Notes 

 upon Hawaiian Plants with Descriptions of New Species and 

 Varieties." By means of a fund raised through private subscrip- 

 tion, Mr. Rock expects in the near future to publish an illustrated 

 book on the native trees of Hawaii, based upon data collected 

 by him during his active connection with the Board. A brief 

 report by Mr. Rock outlining certain interesting finds made by 

 him on the Island of Hawaii, including one rubber producing 

 tree, a Euphorbia, appears elsewhere in this volume as a special 

 contribution.
