SCIENCE constantly is providing us with new thrills—new drama. Consider the proposed flight of the Shenandoah to the North Pole, of which Fitzhugh Green writes on page 31 of this issue. Such a flight may prove the greatest venture into the unknown since the voyage of Columbus.

ONE important point to bear in mind in connection with the proposed polar . exploration by dirigible is that in any case such an expedition can never be merely a spectacular feat of dashing adventure. It is essentially a useful undertaking of exploration, which, if successful, promises results of tremendous scientific and commercial importance.

THIS remarkable picture, based on actual astronomical photographs of the South Polar regions of the moon, indicates that the lunar poles, like those of the earth, are covered with snow. At least, that is the theory accepted by most astronomers in explanation of the fact that the poles of the moon are lighter in color than any other regions of its area.

Why Our Habits Make or Break Us

James J. Walsh
ONE of the most significant stories I ever heard was told to me not long ago by a New England manufacturer. A middle-aged man for several years had been a department head in the shoe factory where he had been employed since boyhood. A new concern offered him an opportunity to take charge of its factory at a generous salary, and he accepted.

A NEW era of cheaper electric power and light for homes and factories is foreseen by engineers in the announcement of the successful development of a revolutionary mercury boiler which, in generating metal vapor instead of steam, promises to make one ton of coal do the work of two and to effect a tremendous saving in the world’s fuel supply.

W. K. Kellogg
LIKE Noah, I have built an ark. Not that I am anticipating another deluge. On the contrary, my ark, though capable of withstanding severe storms, is strictly a land craft. Also, it was not designed to supply a necessity. It was built for amusement—so that I might give full expression to my only hobby, which is motor touring.

COLORFUL, picturesque, and fascinating as is the ancient Chinese game that has become, under its many aliases, one of the leading indoor pastimes of the country, it is doubly enjoyable when played at a properly equipped table. Many costly sets are being used on rickety card tables with loose tile racks that do neither the game nor the set full justice.

MANY recently constructed houses have built-in buffets, dining alcoves, bookcases, and the like, but the majority of small dwellings have none of these conveniences.
