hut, and the largest village of but three. Of the 

 nature of these habitations the reader will have al- 

 ready gathered sufficient from my description of Ka- 

 lutunah's den at Etah. 



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 

 w^ere 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 pains- 

 taking assistant in Mr. Radcliffe. This gentleman also 

 labored assiduously with the photographic apparatus ; 

 and, through his patient cooperation, I was finally 

 enabled to secure a large number of reasonably good 

 pictures. Some valuable collections of natural his- 

 tory 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 inverte- 

 brata that has been made from Arctic waters.^ My 



1 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 Philadel- 

 phia, 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-
