TO
 STUDY GLACIAL BOULDER FORMS
Prof. Wentworth Tells Chamber of Mission and
 Its Main Objective

NcSulIS ol CloSS SIuuy OI gla cial moraines and of glacial bould CTS carried by ice-carrying sub Arctic streams may prove to be tn, solution of how glacial boulder were deposited in gravel beds scat tered from Virginia to North Caro- lima, northern Alabama and north ern Mississippi, the Chamber o Commerce was told today by Ches ter K. Wentworth. Associate Pro lessor of Geology of Washington University, St. Louis.
 He and L. l.. Ray, teaching assist ant in the same institution, art conducting the Investigations which will require work here and al Skagway for several weeks; a sim. liar time on the upper Yukon Riv. CT between Whitehorse and Cir. cle; and additional time in Prince William Sound glacier areas.
 History of Research
 Some 10 years ago, Prof. Went worth said, study in the terraceo gravels in Maryland, considerably south of the known reach of the Pleistocene ice fields, revealed the presence of glacial boulders. Il was at first thought these had been carried into the district by the action of tidal waters, move ment of large bergs, etc.
 Later work in areas of Virginia Tennessee and North Carolina northern Alabama and Mississippi revealed similar boulders beyond the reach of tidal influence. It was then concluded that the bould- CTS had been carried Ly rivers in which ice floes were running.
 Seeks To Prove Difference
 Prof. Wentworth and MT. Ray seek to determine if there is any discoverable difference betwee n boulders deposited by glacial reces- sion and those carried by sub-Arctic streams when they are carrying ice. Superficially, he said, there doesn't seem to be any difference. However, the two scientists are taking exact measurements, noting the effects of the grinding of gla- cial masses and looking for other data.
 After studying the glacier re- gions here and near Skagway, they will visit gravel beds on the Yu- ko nRiver and make similar stu- dies of the boulders in them. They will then visit Prince William Sound glaciers for any additional data needed which may not have been obtained in their earlier work.
 Apply To States
 If it is found that there is a dif- ference in the composition of the two classes of boulders, the crite- ria will be applied to the areas in the States where the original prob lem arose and where 1t may be en- countered in the future.
 Even if there should be no diff ference. Prof. Westworth said, the trip would not be without profit since it will afford an opportunity to observe at first hand glacial action and that of sub-Arctic streams.
 MT. Ray was introduced to the Chamber and expressed apprecia- ton for the courtesies shown them since their arrival here.
 Push Highway Work
 R. HStock. of Wright Construc- ion Company, told the Chamber his firm would rush work on the Glacier Highway project near Swift ser's dairy ranch, for which it holds } contract. Work will be started next week and completed as soon IS possible.
 Anscel Eckmann, chief of opera ions of the Alaska Washington Airways and first flyer to make flight from Seattle to Ju- 1eau, was welcomed back here by he Chamber today.
 Finest Air Flight
 MT. Eckmann arrived Tuesday evening with M. Anderson, San Francisco importer, who has cov- red practically the. whole country y air. MT. Anderson termed the Alaska trip by plane the prettiest md greatest he has ever taken md has promised to return either ate this year or next Spring with ix companions for more extend d flight" MT. Eckmann said.
 Interest in the Seattle Alaska ar 'oyage is growing rapidly. Solar his year, the company has re- eived about ten times as many inquiries regarding it as ever be- ore. The company expects to ring many north later in the yea. |
 Plans For Operations
 The Petersburg, with Pilot Bob 1llis, will remain in Juneau. MI sckmann leaves here tomorrow with the Wrangell for Ketchika I. That ship will be left there and he Sitka taken to Seattle for over
