Awaiting the thawing out of the schooner, I could only employ my time in the immediate vicinity of Port Foulke with such work as I found practicable. The pendulum experiments of the previous autumn were repeated, and several full sets of observations were made for the determination of the magnetic force. The survey of the harbor and the bay was completed; the terraces were leveled and plotted; and the angles on "My Brother John's Glacier" were renewed. In all of these labors I found an intelligent and painstaking assistant in Mr. Radcliffe. This gentleman also labored assiduously with the photographic apparatus; and, through his patient coöperation, I was finally enabled to secure a large number of reasonably good pictures. Some valuable collections of natural history were also made, and in this department I had much useful assistance from Mr. Knorr and Mr. Starr. The ice in the harbor offered them a fine opportunity as the cracks opened, and their labors were rewarded with one of the finest collections of marine invertebrata that has been made from Arctic waters.[1] My*
- ↑ I am indebted to Dr. William Stimpson for a careful examination and comparison of this collection, the results of which were published by him in the "Proceedings" of the Academy of Natural Sciences of Philadelphia, for May, 1863. The collection contains little that is wholly new; but, as Dr. Stimpson has remarked, "They possess great interest from having been found, in great part, in localities much nearer the Pole than any previous expeditions have succeeded in reaching on the American side of the Arctic Circle. They include some species hitherto found only on the European side; and, we may add, the number of species collected by Dr. Hayes is greater than that brought back by any single expedition which has yet visited those seas, as far as can be judged by published ac-*
