physics, geology and Latin who receive $Y,000. 

 It is significant, however, that on the basis of 

 the figures reported most college teaching, par- 

 ticularly in the first two years, is done by men 

 of instructor grade with salaries of $1,000 to 

 $1,200, or by assistants who receive on the 

 average about $500, usually for half-time 

 services. 



VNIVEBSITY AND EDUCATIONAL NEWS 

 Dr. H. T. Summeesgill, superintendent of 

 the New Haven Hospital, has been appointed 

 superintendent of the University Hospital in 

 San Francisco. Dr. Summersgill has arrived 

 to take charge of the present hospital of the 

 University of California Medical School, and 

 to aid in completing the plans for the new 

 teaching hospital buildings, to erect which 

 $615,000 has been given by various friends of 

 the university. Dr. Winford H. Smith, super- 

 intendent of the Johns Hopkins Hospital, re- 

 cently spent a month in San Francisco, com- 

 ing to California as expert adviser for the 

 plans for the new hospital. 



The six-weeks' summer session of the Uni- 

 versity of California, for 1914, enrolled 3,101 

 students. It is expected that next year's sum- 

 mer session, coming while the Panama-Pacific 

 Exposition will be in progress in San Fran- 

 cisco, will much exceed this year's enrollment. 

 The freshman class at the University of Cali- 

 fornia this year, excluding special students, 

 will number over 1,700. 



The first summer school of the George Pea- 

 body College for Teachers has just come to a 

 close. The total enrollment reached 1,006 

 regular students and 99 part-time visitors, 

 coming from 28 states, including all of the 

 southern states. This is possibly the largest 

 enrollment with which any summer school has 

 started. Next year the summer school will 

 continue for twelve weeks instead of six, thus 

 becoming a very integral part of the year's 

 work which is to be divided into four quarters 

 of twelve weeks each.

 Murchison regius professor of geology and

DISCUSSION AND COBEESPONDENCE 

 YOUNG WHITEFISH IN LAKE SUPERIOR 



The literature on the two species of white- 

 fish that are so important commercially in our 

 Great Lakes (Coregonus alhus and C. clupea- 

 formis), as well as unpublished statements re- 

 ceived by the writer from prominent ichthyol- 

 ogists and fish culturists, makes it appear that 

 little, if anything, is known concerning the very 

 young of these fish as they exist in these bodies 

 of water. Where the young whitefish. both 

 native and those that are planted, live and what 

 they feed upon in their natural habitats, consti- 

 tutes an important problem for ichthyologists 

 and fish culturists. Jordan and Evermann 

 (1902),^ writing of Coregonus clupeaformis, 

 say: 



Nothing is definitely known regarding the gen- 

 eral distribution and habits of the young, but they 

 are supposed to remain chiefly in the deep waters 

 of the lake. 



During August, 1913, the writer studied the 

 fish-life of the Whitefish Point Region in 

 Northern Michigan, as one of the investigators 

 sent there by the University of Michigan, 

 with funds given for the work by the Hon.
