 are to investigate in succeeding seasons. 



Miss Alice Eastwood, curator of the botan- 

 ical department of the California Academy of 

 Sciences, has recently returned from a collect- 

 ing trip to Dawson, Yukon Territory, Canada. 

 In order to be on hand for the earliest vegeta- 

 tion, particularly the willows, Miss Eastwood 

 left San Francisco on April 4. The journey 

 from Whitehorse to Dawson, a distance of over 

 three hundred miles, was made in an open 

 stage on runners over the snow and the frozen 

 rivers. Eull material was obtained of all the 

 ■willows from the winter stage in some species 

 to the fruiting stage in all, with leaf specimens 

 from the flowering bushes. Eleven species 

 were found at Dawson within the town limits, 

 and four were added from the higher moun- 

 tains of the Yukon near Dawson. The return 

 trip was made up the river to Whitehorse and 

 every day opportunities for collecting were af- 

 forded when the boat stopped to take on wood. 

 Collections were made at Whitehorse, Atlin, 

 Llewellyn Glacier, Lake Bennet, from Log 

 Cabin to White Pass and Skagway. Small 

 collections were also made on the way to 

 Seattle when the boat stopped at Sitka, Wran- 

 gell and Killisnoo. The trip was made at the 

 instigation of Professor 0. S. Sargent, head 

 of the Arnold Arboretum and through the co- 

 operation of that institution and the Cali- 

 fornia Academy of Sciences. 



Mr. Alfred John Jukes-Brown, F.R.S., 

 lately of the English Geolc^ical Survey, died 

 on August 14 at the age of sixty-three years. 



Mrs. Mary A. Albertson died on August 

 19, at the Nantucket Maria Mitchell Memorial, 

 where she had been librarian and curator for 

 ten years. To her much of the success of the 

 memorial is due. While the astronomical work 

 and the observatory received her faithful at- 

 tention, she early organized a botanical de- 

 partment. Having been associated with Pro- 

 fessor Mitchell in earlier days she knew her 

 great love for flowers and worked to collect 

 a complete herbarium of Nantucket flora 

 (native and introduced). It is gratifying to 



report that she lived to see this nearly com- 

 pleted. 



The TJ. S. Civil Service Commission an- 

 nounces an examination for chief petroleum 

 technologist to fill a vacancy in this position 

 in the Bureau of Mines, for service in San 

 Francisco, Cal., at a salary of $4,800 a year. 

 The duties of this position will be to super- 

 vise and participate in the technologic and 

 other scientific and economic work of the 

 Bureau of Mines in relation to petroleum and 

 natural gas, as to production (which involves 

 a consideration of the oil- and gas-bearing 

 strata), storage, transportation and refining; 

 the prevention of waste; the prevention of loss 

 from underground water encroachment and 

 other economic problems affecting the industry. 

 Graduation with a bachelor's degree from a 

 college or university of recognized standing, 

 special or graduate work in practical geology, 

 and not less than five years' responsible experi- 

 ence in various practicaL petroleum opera- 

 tions, such as would fit the candidate for the 

 above enumerated duties, are prerequisites for 

 consideration for this position. This exami- 

 nation is open to all men who are citizens of 

 the United States and who meet the require- 

 ments. 



Notice is given by the organizing committee 

 of the Nineteenth International Congress of 

 Americanists that the session which was to be 

 held in Washington from October 5 to 10 of 

 this year has been postponed on account of 

 the European war. An expression of opinion 

 was asked of the membership, which has al- 

 ready reached the exceptional number of 

 three hundred, and the almost unanimous reply 

 was to the effect that since the many Euro- 

 pean members and governmental delegates 

 could not attend, it would be impolitic to hold 

 the meeting during the present season. A new 

 date for the session will be decided upon as 

 soon as conditions permit. It is suggested that 

 by putting off the congress till the summer of 

 1915 arrangements may be made to hold a 

 joint meeting with the Pan-American Scien- 

 tific Congress, which is to meet in Washing- 

 ton next season. This would have the great 

 advantage of enabling foreign members to
