...observing the eclipse, one of the most interesting is that of the Navy, which plans to send the Los Angeles, the new dirigible that recently crossed the Atlantic, with an equipment of photographic telescopes, spectoscopes, and probably a moving picture camera, out to sea to observe the eclipse. The exact spot, about 100 miles east of Montauk Point, L. I., where the Los Angeles will be when the two minutes of totality begin has already been decided on by astronomers from the Naval Observatory. The airship will probably not be over 6000 feet up, but this will probably be enough...
...View. Armed only with a smoked glass, it is possible to see the disk of the sun gradually eclipsed by the moon. As more disappears, dusk comes on. Then it may be possible to see shadow bands playing across the land, a phenomenon the exact origin of which is not known. As the eclipse becomes almost complete, it may also be possible to see "Baily's beads." These are little spots of light coming through the valleys of the moon like strings of bright beads. This is as much as an observer in the region of partial eclipse can hope...
...main things that scientists hope to learn from lay observations are the exact borders of the totality belt and the times of the arriving of the total shadow and its departure, to the nearest second. These will help to improve knowledge as to the exact path of the moon...
...brief periods of total eclipses, there has probably been only about an hour made up of scattered minutes here and there, now and then, during which the corona has been under scientific examination. It is known to be connected with the phenomena of sunspots and electrical disturbances, but its exact nature is uncertain. The moon's course also will be closely examined to correct errors in present calculations; for, although the moon travels very regularly in a general way, it is slightly pulled aside this way and that by many diverse factors very hard to caculate. The effect of gravity...
Best of all, however, it appears that where the information is found it is not to be exact and comprehensive. With the large amount of checking up that there is to be done in the getting out of such a book the Student Council and its editor. Herman E. Wiener '20, have done a remarkably good piece of work. There is small ground for criticism and everyone concerned should feel that he has a part in a really big artiste and practical success. Perhaps in the future there will be sufficient funds to allow the preparation of additional pictures...
