Referring to your proposed expedition to the north of Baffin Bay, I have no hesitancy in saying that observations upon the force of gravity at that point would be of great value, as opportunities for work at such high latitudes have been rare. Should a properly organized and equipped expedition to that region be arranged for, I would feel bound to make every effort to provide for the making of such observations.

The Nares Expedition report an extensive series of fossiliferous and other rocks along the western shores of Smith Sound and the region further northward. The strata range from the Laurentian through the Silurian, Devonian, Carboniferous, and Tertiary. The latter contain important beds of lignite at a number of points. The whole series appears to strike northeast and southwest; As the route proposed by you is nearly at right angles to the strike of the rocks, it is probable that the expedition would afford an excellent opportunity to study the whole series in a comparatively short distance, and discover important structural relations as well as valuable economic contents.

I have for many years held to the view that a thorough knowledge of the Arctic regions could be best obtained by continuous exploration. Sporadic efforts are expensive, and the chances of success are very few on account of the yearly changes in the condition of the ice. A small party, such as you have planned, with modest aims, is better than a more pretentious expedition. Hall, Schwatka, Peary, were more successful in proportion to the
