Report of Section IV. 



27th May, 1909. 



Section IV begs leave to report that five sessions in all have been 

 held, the following thirteen members being in attendance, viz. : Dr. 

 Frank D. Adams, Dr. L. W. Bailey, Dr. Robert Bell, Dr. J. T. W. Bur- 

 gess, Dr. R. W. Ells, Mr. Lawrence M. Lambe, Dr. A. B. Macallum 

 (President), Dr. G. F. Matthew, Dr. D. P. Penhallow, Mr. E. E. Prince, 

 Dr. W. Saunders, C.M.G., Rev. G. W. Taylor, and Prof. R. Ramsay 

 Wright. Visitors from other sections and members of the general public 

 were also at times present. Eighteen papers were read either in full, 

 in abstract, or by title, in connection with most of which profitable and 

 interesting discussions took place. The titles of these papers are given 

 in full in the accompanying list. Four new members, chosen from the 

 list of candidates nominated this year, have been elected to the section, 

 viz. : Professors McMurrich and McKenzie, of Toronto University, and 

 Professors A. H. R. Buller and Swale Vincent, of the University of 

 Manitoba. These, with one member elected in tJie general ballot before 

 the meeting of the Society, viz. : Professor Ernest W. McBride, of Mc- 

 Gill University,^ made an addition to the Section of five new members. 



The withdrawal from active membership in the Society of Mr. W. 

 If. Harrington, secretary of the section, as mentioned in the annual re- 

 port, rendered necessary the appointment of a secretary to act during the 

 general meeting, and Mr. Lawrence M. Lambe was elected to the office. 



Section IV asks that the Council of the Society be requested to con- 

 sider the advisability of defining more accurately the scope of the several 

 sections, so as to determine the proper position of the science of geo- 

 graphy, there being some doubt at present to which of the sections it 

 should be regarded as most closely related. 



1 Prof. McBride has since removed to England.
