sure from the west was expended extended north- 

 ward to the latitude of the Liard River at least. 

 Northward there seems to have been less of a 

 barrier and the alignment in the Kocky Moun- 

 tains, preserved from the boundary line north- 

 ward to that point, is broken and the Mackenzie 

 Mountains represent the eastward extension of 

 the lines of weakness developed by the lateral 

 compression. The eastern margin of this earth 

 movement affects the area under study. 



The influence of rock structure on quarrying 

 methods: Oliver Bowles. While brief reference 

 is made to the effect of joints on drilling and 

 blasting limestone, chief emphasis is placed on 

 the importance of rock structures in dimension 

 stone quarrying, and the influence of such struc- 

 tures on the quality of the finished products. 

 Reference is made to the manner in which mar- 

 ble, slate and granite quarrying methods should 

 be modified to conform to best advantage ivith 

 such rock structures as slaty cleavage, bedding, 

 grain and rift. The great need of a more ex- 

 tended application of geology to quarry prob- 

 lems is emphasized. 



The fluorspar deposits of the Madoc district, 

 Ontario : M. E. Wilson. The fluorspar deposits 

 of the Madoc district are all veins oeoupj-ing 

 fault fissures of post-Ordovician age, and are 

 similar in type to the fluorspar deposits of the 

 central United States and the north of England. 

 The principal features that distinguish the de- 

 posits are that they occur in part in faults on 

 which the displacement has been horizontal and 

 in a region where igneous rocks of later age than 

 the Pre-Cambrian are unknovm. The evidence 

 bearing on the origin of these deposits therefore 

 lends greater support to the hypothesis that they 

 have been formed through the agency of meteoric 

 waters than in the case of other fluorspar de- 

 posits of the Madoc type. 



The geology and surface features of the 

 Torngat Mountains in northern Labrador: A. P. 

 Coleman. The rocks displayed in northern 

 Labrador are chiefly Laurentian granites and 

 gneisses and Grenville sedimentary deposits. On 

 the upturned edges of these rocks there are much 

 later Pre-Cambrian sediments with gentle dip. 

 The earlier Pre-Cambrian rocks, once forming 

 great ranges of mountains, have been cut down 

 to a peneplain of which the northeastern edge 

 has been elevated, forming a tableland. The 

 edge of the tableland has been carved by great 

 valley glaciers into the wildest mountains of 

 eastern North America, and a few small glaciers 



still survive. This glacial work has excavated 

 some of the most impressive fiords to be found 

 in America. 



Gaspe Peninsula: the country, its geology and 

 economic possihilities: F. J. Alcock. This 

 paper is a briei description - of the physiography 

 and geology of Gaspd peninsula, with particular 

 reference to an area in the initerior where a 

 variety of igneous rocks occur. Associated with 

 these are important deposits of zinc and lead 

 which present certain features of interest. 



The geology of oil in Canada: D. B. Cowling. 

 A discussion of the oil producing areas and pros- 

 pective oil fields of Canada. 



No program was prepared by Section E on the 

 afternoon of December 29 in order that the mem- 

 bers might meet with Section M (Engineering) 

 and hear a number of papers of interest to geolo- 

 gists and geographers. In the evening a combined 

 dinner for Sections E and M was held in the Music 

 Room of Hart House, University of Toronto, 

 where a very enjoyable time was spent.

SECTION Q— EDUCATION 



Section Q held session from December 28 

 to 30. A dinner and smoker was held on Wed- 

 nesday evening. The dinner was followed by 

 an address by Dr. R. M. Yerkes, of Washing- 

 ton, entitled "Remarks Concerning the Research 

 Information Service of the National Research 

 Council and Its International Relations." On 

 Friday morning a session was held in conjunc- 

 tion with Section I. At this session E. K. 

 Strong, Jr., of the Carnegie Institute of Tech- 

 nology, delivered his retiring presidential ad- 

 dress for Section I, and Dr. Charles H. Judd, 

 of the University of Chicago, delivered his re- 

 tiring vice-presidential address for Section Q 

 on "Technique of Scientific Revision of the 

 Ciu'riculiun." A joint session of Section Q and 

 K was held on Friday afternoon, at which a 

 symposium on "An International Auxiliary 

 Language" was given. 



The average attendance at the final sessions 

 included in the program was good throughout, 

 including from 125 to 250 educators and 

 psychologists.
