Two observers continued the work of the Magnetic Survey of 
Canada. Forty-eight stations were occupied along the Canadian 
Pacific Railway between Chapleau and Moosejaw, and forty-four in 
southern and south-western Ontario. The average distance apart of 
stations was twenty-five miles: At each station the declination, in- 
clination and horizontal intensity are determined, also the diurnal 
variation of declination. Another Kew dip-circle was added to the 
instrumental outfit during the year, and a Kittel mean time pocket 
chronometer. 
The longitude of the transit house at Winnipeg (on Fort Osborne 
barrack ground), which is to serve as a base for longitude determinations 
in the prairie provinces, was determined early last summer by tele- 
graphic exchange of time with Ottawa, using one of the copper wires 
of the Canadian Pacific Railway Company’s telegraph. The low re- 
sistance and self-inductance of this wire made it possible to dispense 
altogether with repeaters, thereby materially increasing the accuracy 
of the exchanges. The time of transmission was only six one-hundredths 
of a second, indicating a velocity of over 20,000 miles a second, and was 
remarkably constant throughout the series of exchanges. 
Six other stations were occupied in the west, the longitudes being 
determined from Winnipeg; and two stations were occupied in Western 
Ontario, the longitudes being determined from Ottawa. 
Work on the International Boundary Surveys has been actively 
continued. The final monumenting of the 141st meridian of West 
longitude, with the triangulation and topography, was completed to a 
point midway between Yukon and Porcupine rivers, and the pro- 
jection of the meridian was carried to a point ten miles north of the 
latter river. Two surveying parties were employed on the boundary 
of the Alaska Coast Strip, and one on the water boundary between 
Vancouver Island and the State of Washington. About 250 miles of 
the re-survey of the 49th parallel, along the southern boundaries of 
the provinces of Saskatchewan and Manitoba, were completed, as also 
the survey of parts of the boundary between New Brunswick and Maine 
on the St. Croix and St. Francis rivers. 
The operations of the Geodetic Survey have comprised triangu- 
lation observing in Ontario and Quebec, reconnaissance in the western 
peninsula of Ontario, west from Lake Superior, on the coast of British 
Columbia, and in the Maritime Provinces. Precise levelling has been 
carried on in Nova Scotia, Ontario and Manitoba.
