REPORT OF THE DIRECTOR AND STATE GEOLOGIST 1903 11 



map has been prepared' to show the distribution of beaches, 

 whether marine or lacustrine. The attempt made last season to 

 discriminate the different classes of drift of glacial origin in the 

 low submerged tract below the 600 foot line was perforce 

 abandoned for most of the area, when it became evident that the 

 glacial deposits had been worked over by the action of waves and 

 currents during the epoch of submergence so as to confuse and 

 commingle materials of diverse origin. 



For the purpose of obtaining information coneerning the tilted 

 attitude of the beaches and the marine limit in this district, two 

 visits were made to outside points in Canada, the first to the 

 vicinity of Ottawa, and the other to the isolated igneous masses 

 near St John's and Beloeil, in Quebec. 



In the case of Monnoir or Mt St John near St Gr^goire, no 

 definite upper limit of wave action was observed. The northern 

 and eastern slopes we're largely bared of drift. What appear to 

 be fractures partly filled with blocks riven from their walls, are 

 striking features in the upper part of this mount on its eastern 

 aspect. The fractures extend in a northwesterly and south- 

 easterly direction. Professor Woodworth could not determine at 

 the time of his visit that the narrow openings were due to excava- 

 tion of nonresistant material by waves. 



A visit to Beloeil showed heavy pebble beaches developed about 

 the base of this mountain on the west up to an elevation of from 

 310 to 320 feet above sea level by aneroid compared with .the hight 

 of the rail at St Hilaire. An ascent of the northwestern part of 

 the mountain showed no traces of beaches or wave action, but; the 

 slopes were everywhere too steep to record clear indications of 

 marine action. 



From Ottawa, a reconnaissanee was made of the slopes of 

 Kingsmere mountain, northwest of that city, between Chelsea on 

 the Gatineau, and Kingsmere postoffice. Traces of shore lines 

 were found between Old Chelsea and Kingsmere postoffice at 

 480, 550, 640 and 705 feet by aneroid set at Chelsea Station. A 

 heavy deposit occurs along this road at about 800 feet ; but Profes- 

 sor Woodworth was not able to find the criteria which would
