of the month. September and October were spent in packing collec- 

 tions, studying special industries and visiting the Sulka country at 

 Mope and the neighborhood of Mt. Varzin. Very rare Sulka and 

 Baining masks and other things were obtained. Early in November 

 Dr. Lewis left for the British Solomon Islands. He has made a care- 

 ful study of the culture of these different regions, Berlin Hafen and 

 Huon Gulf in German New Guinea and the southwest coast of New 

 Britain, also full collections in those regions, supplemented by many 

 photographs. Many scattering specimens have been secured from 

 other regions which supplement the fine collections already possessed 

 by the Museum. 



The Dendrologist has completed his work in northern Georgia 

 bringing in from that field 390 elements toward the North American 

 Forestry monographs now preparing for installation. He then pro- 

 ceeded to the Pacific Coast where he will continue uninterruptedly in 

 the field until he has secured the elements of the species to be repre- 

 sented from the region west of the Rocky Mountains. His first carload 

 of material from the Coast has already reached the Museum. Together 

 with his dendrological work he is making general collections for the 

 economic and herbarium series. Roy A. Dixon made a trip to Texas, 

 collecting in Walker, Montgomery and Harris counties; he secured 143 

 species for the herbarium and 477 duplicates for exchange. O. E. 

 Lansing, Jr., continued his local collecting, returning 128 specimens for 

 the herbarium and 470 duplicates for exchange. 



During the latter part of the summer, a number of large feldspar 

 quarries in Maine were visited by the Curator of the Department of 

 Geology for the purpose of securing specimens of the rare minerals 

 contained in the pegmatites and a series illustrating the feldspar industry. 

 Quarries in Auburn, Poland, Hebron, Norway, Georgetown and Top- 

 sham were visited and from nearly all of them valuable material was 

 obtained. At Poland the rare good fortune was had of being present 

 when one of the most valuable pockets of gem tourmaline ever found 

 was opened. The opportunity was improved to collect series of the 

 associated minerals and some steps were taken toward securing some 

 of the gem material at a later date. Some excellent specimens of 

 apatite and of the rare mineral herderite were also obtained at this 

 locality. At Georgetown some large specimens of white and yellow 

 beryl were collected and at Hebron rare forms of columbite, triphylite, 

 and other rare minerals. At all the quarries typical specimens of the 

 feldspars and pegmatites mined were obtained and at the adjoining 

 mills various grades of the ground product. A striking series of trap
