MEN IN TENT CALCULATING EARTH'S MAGNETIC FIELD

Persons walking across the quadrangle between Langdell and Pierce Halls today will notice a mysterious looking tent pitched there. The tent, which was erected at daybreak this morning, contains several members of the United States Coast and Geodetic Survey who are making extremely delicate calculations of the earth's magnetic declination, dip, and field strength.

Conducting a nation-wide tour, these men will obtain valuable scientific data by making many observations of the earth's ever-changing magnetic properties. Next stopping place of the expedition will be the Harvard Observatory at Blue Hill.
