When an Eskimo is attacked with _piblokto_ indoors, nobody pays much attention, unless the sufferer should reach for a knife or attempt to injure some one. The attack usually ends in a fit of weeping, and when the patient quiets down, the eyes are bloodshot, the pulse high, and the whole body trembles for an hour or so afterward.
The well-known madness among the Eskimo dogs is also called _piblokto_. Though it does not seem to be infectious, its manifestations are similar to those of hydrophobia. Dogs suffering from _piblokto_ are usually shot, but they are often eaten by the Eskimos.
The first winter moon came early in November, and on the 7th MacMillan started for Cape Columbia for a month of tidal observations, taking with him Jack Barnes, a sailor, Egingwah, and Inighito and their wives. Poodloonah, Ooblooyah and Seegloo went as MacMillan's supporting party, to carry supplies, and Wesharkoopsi and Keshungwah started for Cape Richardson to bring back the musk-ox skins which had been left there during the fall hunting trips.
The tidal observations by MacMillan at Cape Columbia were made in connection with the tidal observations which were constantly going on at Cape Sheridan during the fall and winter, and with those taken later at Cape Bryant on the other side of Robeson Channel. These tidal observations of the expedition of 1908-09 were the farthest north of all continuous series ever recorded anywhere, though similar observations had been taken by the Lady Franklin Bay Expedition at Fort Conger, about sixty miles southwest.
Marvin and Borup, during the November moon, continued the tidal observations at Cape Sheridan. The tidal igloo, which was built on the ice just inside the tide crack, about one hundred and eighty yards from the ship, was an ordinary Eskimo snow igloo and was used as a protection to the men in taking the observations at the tide staff. This staff, about twelve feet long, was driven into the bottom, and its length was marked off in feet and inches. As the tide rose and fell, the ice and the igloo moved with the water, but the staff remained stationary, and by the position of the ice upon the staff we measured the tides, varying with the day, the moon and the season.
