"In navigating the seas, if the course is determined by compass and the declination appearing on the chart should be as much as three degrees off, which it frequently is, this could make a difference of about 30 miles a day, and in three or four days a vessel might steer 90 or 100 miles off the course. It is said that if a vessel were to steer from the north Atlantic for Falmouth by the charts of a century ago her course would bring her, without the intervention of any other means of determining the situation, to the Orkney islands in north Scotland."
Dr. Louis A. Bauer, director of the department of terrestrial magnetism of the Carnegie institution, joined the Carnegie on the Isthmus and will finish the voyage to Washington. The Carnegie is a non-magnetic vessel, constructed and equipped with virtually no iron, or steel or other magnetic substance aboard her. She is a sailing vessel, having a small auxiliary engine, capable of making four knots. The engine and the stove in the galley are of brass, the anchors are bronze. In the building of the hull locust spikes were used. There are 23 in the crew, including six scientists.
Their observations
BEARS ARE PLENTIFUL
"Party" of Ton of Them Stopped an Automobile in Road.
That bears are as plentiful in northern Columbia county, Pennsylvania, as rabbits is the declaration of many who have visited that section.
Returning from a trip to the mountains, Frank Hosier, Ralph Knouse, Harry Welliver, A. J. Hartman and Omar Ash say they were compelled to stop their automobile because of a  "Bear party" in the road ahead of them. There were ten bears romping the highway, two old ones and eight cubs.
