210 ■ FOSSIL FLORA OF ALASKA— KNOWLTON. 



Dr. Newberry's successor, Dr. Arthur HoUick, of Columbia College. 

 They are quoted in the present paper as "Plates." 



In 1887, Lesquereux published a paper entitled "List of Recently 

 Identified Fossil Plants belonging to the U. S. National Museum, with 

 descriptions of several New Si)ecies."* This comprised a large amount 

 of material that had been accumulating in the department of fossil 

 plants since the founding of the Smithsonian Institution, Among 

 them were a few species recorded as having been collected in the vicin- 

 ity of Sitka, by E. W. Nelson, t and at Cape Lisburn by H. D. Woolfe. 

 The specimens from the latter place appear to have been a part of the 

 collection that was described from the same locality in the following 

 year, they having been accidentally separated. 



In 1888, as stated above, Lesquereux published f an enumeration of 

 plants obtained at Cape Lisburn by H. D. Woolfe. This collection 

 included 10 species of which number only one was regarded as new to 

 science. 



The last paper dealing with pre-glacial fossils is one by Felix § in which 

 he describes two species of silicified wood. The one obtained by Dr. 

 Krause of Berlin on a basalt mountain south of Dana<1ka|i and the other 

 from Copper Island, 1] a small island in the Southwestern part of the 

 Bering Sea. 



Mr. F. H. Herrick is t\\Q only one, so far as 1 now know, who has iden- 

 tified any of the interglacial wood. His paper, "Microscopical Exami- 

 nation of wood from the Buried Forest, Muir Inlet Alaska" is published 

 as Supplenjent in to Harry Fielding Reid's paper "Studies of Muir 

 Glacier, Alaska."** Mr. Herrick identified the Avood submitted to him 

 with the tide-land spruce [P'wea ISitchefisis, Carr.) now living about the 

 glacier. 



A number of ])ieces of wood from the buried forest Muir Glacier, 

 obtained in 1892 by Mr. Reid, were submitted to me for examination. 

 The report on them will be published also as an appendix to Mr. Reid's 

 paper, soon to appear in the National Geographic Magazine, The spe- 

 cies observed are recorded in their proper systematic position in the 

 present paper. 



The latest work dealing with fossil fiora of Alaska, and this only 

 incidentally, is the U. S. Geological Survey correlation paper on the

1 1 am iuformed by Mr. Nelson that he never visited Sitka and did not bring back 

 any fossil plants from Alaska. This throws doubt on the specimens so recorded, 

 and their locality, and collector remains unknown. I have retained them, howeverj 

 as recorded by Lesquereux.

^ This is really extra-limital, but has been inclnth'd as being more nearly related to 

 the Alaskan province than to any other.
