On May I, I928 the Carnegie left her wharf in the city of Washington to begin a new series of scientific observations on the oceans of the earth. On the way to England the weather was unfavorable, it being necessary to wait ten days off the entrance to the English Channel on account of gales. The copper sheathing started to peel off at the water-line and both cabin and staterooms were flooded at times.
At 29 stations on the voyage observations of declination were made with the marine collimating compass. Chart corrections ranging from ~-I ยฐ .7 to -I ยฐ .o were found for declination, while the largest error for inclination amounted to o ยฐ .9. The vessel was stopped at six stations on the only days when the weather permitted and observations of the temperature of the water were made and samples of the water were collected. Water-bottles at one place failed to operate. "Some animal of the deep had fouled the wire."
From England the Carnegie went to Hamburg, where Dr.
Kolhoerster delivered an instrument for observing the penetrating radiation associated with his name and that of Millikan in the United States. Thence the voyage led toward the Faro~ Islands and on to Iceland. Off Iceland the vessel crossed her track of I914. Reykjavik was at last reached on July 20.
Thus has begun the long voyage of the Carnegie that will furnish fresh data for magnetic charts of the water areas of the globe and throw light upon the secular variation of the magnetic elements of the earth.
