between Vancouver Island and the mainland. The manner in which the 

 re-survey of each section should be carried out is prescribed. The treaty 

 contemplates no change of boundary, but merely the restoration of the 

 original monuments, where such exist, and the placing of additional ones 

 where necessary, all in accordance with the intent of the various treaties 

 and in agreement with the original surveys made under them. In Pas- 

 samaquoddy Bay only is there an unsettled question, for settlement of 

 which provision is made in the treaty. 



The Geodetic Survey of Canada. 



The work accomplished by the Geodetic Survey Staff during the 

 season of 1908 is briefly as follows: — 



Two Observing parties, measuring horizontal angles, were in the 

 jfield during the whole season, but on account of the prevalence of dense 

 smoke very little work was accomplished. The district covered lies be- 

 tween Brockville and Toronto. 



Eeconnaissance Surveys were conducted in the Maritime Provinces, 

 in the Province of Quebec, in Western Ontario and along the Inter- 

 national Boundary west of Lake Superior. This latter reconnaissance 

 was for the purpose of making a primary triangulation to control the 

 survey of the International Boundary along Pigeon Kiver. The recon- 

 naissance in the Province of Quebec, which embraced all of that part of 

 the Province lying southeast of the St. Lawrence Eiver from Montreal 

 to a point some thirty miles below the city of Quebec, and also one row 

 of triangulation stations to the northwest of the St. Lawrence Eiver, a 

 sufficient distance back therefrom to secure high enough points to con- 

 trol the country to the southeast, was most gratifying in its results; it 

 was successful in securing an excellent system of quadrilaterals and 

 large five and six sided figures with central points. 



The work of Signal Building was continued west of Toronto as far 

 as Woodstock or thereabouts. In the Maritime Provinces reconnaissance 

 has been satisfactory. The stations for a triangulation extend from 

 Chamcook Mountain in the southwest corner of New Brunswick, to the 

 northerly extremity of Cape Breton Island, embracing a district about 

 fifty miles wide between those points, including the easterly portion of 

 Prince Edward Island. Chamcook Mountain is one of the primary 

 triangulation stations of the United States Coast and Geodetic Survey, 

 and in conjunction with Trescott Eock — another primary station of the 

 same survey — direct connection is made with the Geodetic Survey of the 

 United States. 



In 1908 two Geodetic Levelling parties were employed, and a line 

 of levels was carried from Coteau Junction — thirty-eight miles south
