Captain MacMillan spent two years in graduate work at the University after receiving his degree from Bowdoin. Since, his life has been that of an explorer of the polar regions. He accompanied Peary, who had been interested in him for many years, on the trip when the north pole was discovered, and he has since made many discoveries which stamp him as one of the world's greatest explorers...
Beyond the polar seas, beyond the flows of ice and snow, lies a blind spot on the map, a never-never land to the explorers of the past. Peary, Scott and Stefanson have gone on to a greater discovery and the land of the Northern mysteries is still left untouched to challenge such men as Amundson, McMillan, and Olgarssor to add the last chapter to the history of continental discovery...
There are masses of goats, and a polar, and different kinds of mouse
...Einthoven's device records the fluctuations of this current by means of two wires of quartz, so fine that they are invisible even under a microscope, unless thrown into relief by light against a dark background. These wires are threaded across the magnetic field formed between the polar ends of an electromagnet. In each pole of the magnet is screwed a microscope, one lending light, the other enlargement. Rubber manacles are placed over the wrists of the patient. Under each manacle is a salt pad (electric conductor) from which a wire runs, bearing the current of the body...
When the Shenandoah broke loose some months ago from its mooring mast at Lakehurst, N. J, and avoided destruction by supreme skill, cautious Mr. Coolidge vetoed all plans for a Polar flight. Now that the U. S. has two large dirigibles in its possession, and such perfect command of both ships has been demonstrated again and again, there is revived talk of the expedition. General Mason M. Patrick in fact wants the ZR3 transferred to the Army, and a race between ZR3 and Shenandoah "to either the North or the South Pole." There would be sufficient thrill to a polar...
