 "To take our thoughts for few hours away from such discouraeing sight, we unpacked our new motion picture machine. Our Delco plant, equipped with Exide batteries, with which the Bowdoin was lighted. sup piled us with power. We simply snapped button and were off into the busy world to the south. If the donors of the machine only knew how we enjoyed that hour or so up in Fox Channel locked in the ice, and the many, many happy hours we spent later in winter quarters, know they would feel we'll repaid for their gen. , erosity".
 In another place he says "We in vited the Eskimos to come on board to their first moving picture show. We showed them kinograms of life in the States and in various parts of the world, and ended with reel of the Eskkimos at Etah, North Greenland, and in Hudson Bay. What their feel ings were it is hard to imagine. Some were so absorbed that they sat like stone images, while others gave vent to their feelings by a deep 'Ke-pee (wonderfuD"
 Even we who are accustomed to the wonders of modern invention might we'll echo the Eskimos' long drawn out and many times repeated Ike pee" at the instruments designed and built for this expedition by the Car negie Institute.
 These instruments for the observa- tion of the variations in local terres- trial magnetism were in charge of Ralph H. Goddard, one of the scien- tists of the expedition, and might be termed an electrical-chemical-mechan- ical Sherlock Holmes on the trail of the magnetic pole in the home of the Aurora Borealis. Perhaps no scien- tist would say that, but what they do say is no more intelligible to the av- craze man.
 The observatory in which the in- struments were located was on the shore and about 400 feet distanct from the Bowdoin. It was built after the style of a large refrigerator, only it's purpose was to keep the cold out and not in. The inside dimensions were 12 it. by it. high, and three thicknesses of plaster board with l Ha inches air space between were used ir building the instrument room. Then a stone was erected around the first building leaving a three foot passage all around the inner room. The stone building was roofed with tinbers GOV, cred with canvas and the whole ex. terior was plastered over with abou, six inches of packed snow. The en' trance was protected by an Eskimo type of ice house called an igloo. Al together there were five doors to pass through in entering the instrument room. Two oil lamp heaters were kept going in the three foot passage way and thus the temperature was constantly maintained at about minus five centigrade.
 The inner or instrument room was really photographic dark room filled with self-registering magnetic varia' tion apparatus. For instance, one sci of three instruments had magnetic needles with tiny mirrors on one end A two-candle power lamp backed by a mirror reflector was so focused as to cast ray of light on to the mag netic needle mirrors which in turn reflected back pencils of light to a large recording cylinder of sensitizeo paper upon which was thus written the story they had to tell.
 The recording cylinder was aptly called the peanut roaster" by Jo' Small, the Cape Cod mate of the Bowdoin. The film-like paper was re. newed each day for the record of the next twenty-four hours. Altogether there were seven of these pencils oi light writing their daily hieroglyphics on the megaetogram for later inter pretation by the scientists of Carnegie Institute.
 One kept track of the variation in temperature. Three were guardians of the "base lines" and checked the faithfulness of the instruments III sticking to their respective jobs. The other three were the ones which did the tattling of the inner secrets oi the newly discovered region which nc white man had ever seen before. One measured vertical intensity, another the horizontal intensity and the third by the clever use of trosion head measured the variation in declination; that is, the variation of the magnetic
