4 GEOLOGICAL SURVEY OP CANADA. 



immediate adjoining territories are concerned, brought into agree- 

 ment. 



In the counties of Argenteuil, Terrebonne, Montcalm, Joliette and 

 Berthier about 1,700 .square miles bave been examined in detail by 

 Messrs. Vennor and Ord, particular attention having been paid to 

 ascertaining the distribution of the Laurentian crystalline limestone 

 bands and serpentines, with -which most of the economic minerals of 

 the region, iron ore, plumbago, phosphate, mica and asbestos are 

 associated. . 



On the south side of the St. Lawrence Mr. A. Webster has examined 

 an area of about 1,700 square miles, tying, for the most part, within 

 the great gold-bearing belt on the head waters of the Chaudiere, the 

 St. Francis and the Salmon Rivers, including the country around Lakes 

 Aylmer, St. Francis and Megantic. 



Mr. Richardson's attention has been devoted to making certain 

 measurements and examinations between River du Loup, the 

 Temiscouata road and the Trois Pistoles River, which were required 

 to fix the out-crops and define the limits of the various formations. 

 This work should now be extended north-eastward to Gaspe, including 

 a detailed exploration t of the Schickschock Mountains. 

 Work in New The progress of the work in New Brunswick has been satisfactory, 

 Messrs. Bailey examinations and surveys having been made in central and southern 

 Eiis. e New Brunswick, in Carleton and York counties, by Messrs. Bailey, 



Matthew and Broad of about 1,500 square miles, including 600 miles of 

 measurement by odometer and pacing; and in northern New Bruns- 

 wick, by Mr. Ells, in the counties of .Northumberland, Restigouche 

 and Gloucester, including the coast of the Baie des Chaleurs from 

 Bathurst to Campbeltown. Some interesting photographic illustra- 

 tions of the country have been secured, and about 1,000 miles of track 

 surveys have been made. 

 Explorations In Cape Breton an. area of about 500 square miles, lying between 



by Mr. Fletcher t- . x ' J ° 



in Cape Breton River Inhabitants Basin on the south and Whykokamagh on the north, 

 has been closely surveyed by Mr. Fletcher, all roads, brooks and tracks 

 having been measured by odometer, with the view of constructing an 

 accurate and detailed map of this important mineral district, in which 

 deposits of coal, petroleum, gypsum, marble and other valuable 

 minerals have been found, and give promise of becoming economically 

 available. 



Some of the detailed reports of these explorations are now sub- 

 mitted. The field- notes and the measurements of the others have been 

 worked up and plotted, but it is deemed advisable to defer their publi- 

 cation for further and more extended observations in the respective
