J. P. AuLT, ON Magnetic Work in Northern Canada, June to September, 1908. 



Actinginaccordance with instructions of June 2, 1908, I left Washington June 5 for Winnipeg, 

 Canada, accompanied by Observer C. C. Stewart as assistant, in order to establish a series of 

 magnetic stations in Northern Canada. The following instrumental outfit was assigned to the 

 party: magnetometer No. 7, dip circle No. 172 with dip needles i and 2, and intensity pair 3 and 

 4, pocket chronometers Kittel Nos. 256 and 257, and observing tent No. 7. 



Upon arrival at Winnipeg, June 8, Mr. C. C. Chipman, commissioner of the Hudson's Bay 

 Company, was consulted regarding the best route for a trip into the north of Canada and as to the 

 necessary arrangements. The station at Winnipeg was reoccupied on June 9 and 10, the party 

 leaving Winnipeg the evening of the loth for Prince Albert. Here final arrangements were made 

 and the required outfit was secured for a canoe trip into the northern provinces, the route followed 

 being by way of Cumberland House, Sturgeon Lake, Frog Portage, Churchill River, and north 

 to latitude 60. The return was made over the same route as far as Cumberland House and 

 thence down the Cumberland River to The Pas and from there to the Canadian Northern Railway 

 at Hudson's Bay Junction, over the recently completed section of the new railway to Fort Churchill. 



The trip to Cumberland House was made on board the Hudson's Bay Company's steamer 

 Saskatchewan and occupied 2 days, the start being made from Prince Albert on June 13. At 

 Cumberland House two guides were secured and after a delay of 6 days, on account of adverse 

 weather conditions, our canoe trip was begun on June 22; this trip consumed 68 days, the north- 

 ernmost point. Canoe Limit, being reached on August 2. The return to The Pas was accom- 

 plished by August 29. Prince Albert was reached on September 8, and from there I returned 

 to Washington, D. C, on September 18, leaving Mr. Stewart to carry out further work on the 

 railways of Canada (see Mr. Stewart's report). 



The total time required for the work was from June 5 to September 18, or 105 days, giving an 

 average total time of 5.5 days per station; the time spent in traveling to and from the field was 

 12 days. The total travel approximated 5,800 miles; the field travel was 1,800 miles, 1,600 of 

 which were by canoe, giving an average of 95 miles field travel per station. During the 1,600 

 miles by canoe, 71 portages were made varying in length from 100 yards to 2 miles. It rained on 

 36 of the 68 days spent in canoe travel, but most of the rains were of short duration and caused 

 little delay. We were delayed 6 days at Cumberland House before starting the canoe trip, and 

 5 days at The Pas on account of the weather and the necessity of waiting for a hand-car. 



During the expedition the following stations were occupied:
