large and small. These were considered rep- 

 resentative of the groups to which they be- 

 long, and thus the averages may be considered 

 typical. The per cent, of inbreeding varies in 

 different sections of the country as well as in 

 different kinds of schools, as follows: 



Per Cent. 



Six women's colleges average 12.4 



Fourteen western schools average . . 23.5 

 Five southern schools average .... 25.3 

 Sixteen state universities average . 26.2 

 Twelve eastern schools average ... 29.6 

 Twenty-two central schools average 33.7 



The table shows the kind of degrees the in- 

 bred instructor received from his alma mater. 

 Captions have also been made for those hav- 

 ing studied at the alma mater, either as un- 

 dergraduates or as graduates, without receiv- 

 ing a degree. Persons were not entered under 

 these two captions unless a considerable 

 amount of work was thus done in the alma 

 mater. Frequently more than one first, sec- 

 ond or third degree was obtained. Lack of 

 space prevented showing this in detail. M.D. 

 and C.E. are counted as third degrees. West- 

 ern schools means west of the Mississippi. 

 Eastern schools means schools east of Ohio.

THE TENTH INTERCOLLEGIATE NEW ENG- 

 LAND GEOLOGICAL EXCURSION 



The tenth Intercollegiate New England 

 Geological excursion was taken Saturday, 

 October 22, in the vicinity of Hanover, N. H., 

 under the leadership of Professor J. W. 

 Goldthwait, of Dartmouth College. 



Friday evening a preliminary meeting at 

 which papers were read and discussed was 

 held in the geological lecture room of Butter- 

 field Museum. This meeting was attended -by 

 twenty-one persons. Professor J. W. Gold- 

 thwait gave a summary of his work on the post- 

 glacial subsidences and uplifts in the St. Law- 

 rence Valley. Professor D. W. Johnson dis- 

 cussed the evidence of recent subsidence on 

 the New England coast and showed that the 

 apparent sinking of the land may be accounted 

 for in other ways. His recent studies show 

 that there can have been no change in the 



level of the New England coast in the last 

 1,000 to 3,000 years. The Nantasket beaches 

 show that there has been no change in level in 

 at least 1,000 years. Professor B. K. Emerson 

 gave a summary of the glacial geology of the 

 Connecticut Valley. 



The excursion Saturday morning was taken 

 to the Connecticut Valley esker to study its 

 relation to the other deposits in the valley. 

 The clays of the " highest terrace " were 

 shown to have been deposited in the still 

 waters of a lake formed by a temporary dam 

 of some sort, perhaps a ledge of rock which the 

 stream later abandoned as it cut a new chan- 

 nel into the softer glacial deposits of the 

 former valley. The deltas at the mouths of 

 the tributary streams at altitudes above the 

 " highest terrace " seem to have been laid 

 down in the lake in which the silt of the 

 " highest terrace " was deposited. After a 

 study of the unprotected terraces and aban- 

 doned, incised meanders of Mink Brook the 

 party were obliged to stop on account of rain. 



Representatives were in attendance from 

 Amherst, Brown, Dartmouth, Harvard, Holy- 

 oke, Massachusetts Agricultural College, Mid- 

 dlebury. Smith, University of Vermont, Wel- 

 lesley, Wesleyan, Williams. 



No announcement was made as to the place 

 of the next excursion.
