On June 8 the attention of many people in this country was distracted from the war for a few minutes to contemplate the wonderful phenomenon occurring in the sky, this being the eclipse caused by the passage of the moon between the sun and the earth.

Eclipses in which the sun is partially obscured by the moon are fairly common, but it is rare for any portion of the earth to be visited by a total eclipse, in which the moon's disk completely covers that of the sun and for a few minutes produces an artificial and temporary night.

The eclipse of June 8 was the first eclipse in this century to be total in the United States, and over the band of totality it naturally excited the greatest possible interest. This band of totality extended from the Pacific to the Atlantic coast but was only about sixty miles wide, so that for most of the country the eclipse was seen only as a partial covering of the sun's disk by that of the moon. The partial eclipse lasted for about two hours, but at some places in the east the sun set before the moon was clear of its disk.

One of our readers had the happy thought of photographing the eclipse at intervals from the moment when the moon's disk was first seen touching that of the sun until the sun was hidden behind the trees of the horizon. He used an 8 x 10 camera and lens with a Standard Ortho-non plate, and gave eighteen exposures in all, one exposure being made every five minutes. The lens was closed to its smallest opening, the shutter set at 1/100th of a second, and after seeing that the camera was rigidly set in its position, the shutter was snapped at five minute intervals. The photograph shows that at the beginning this gave too much exposure so that some of the first exposures are buried in halation, and the reflection of the sun's image from the various surfaces of the lens has produced spots of light on the negative of the kind known to the opticians as "flare" spots. But as the sun sank lower in the atmosphere and its light began to be obscured by the absorption of the air, the exposure gave admirable results.

To the astronomers, a total eclipse offers a rare and valuable opportunity. From the sun there are continually shooting out flames of incandescent gas which cannot be seen because of the intense

RED TERRA COTTA TOBACCO JAR LINED WITH BLACK The Griffins are yellow against a blue ground, the geometrical design is yellow, reddish brown and blue light of the sun itself, while around the sun there spreads out into space a wonderful phenomenon called the "corona," which is seen in an eclipse as a ring of pearly gray light, growing fainter and fainter as it recedes from the sun and spreading out into space on all sides. In order to photograph these phenomena a number of scientific expeditions went from the observatories to the belt in the country where the eclipse was total, and setting up temporary observatories with elaborate apparatus, they photographed the corona and the "prominences," as the flames of incandescent gas are called, and made measurements of the phenomena associated with the sun which can only be studied effectively when the sun's disk itself is eclipsed.

By courtesy of Professor Edwin B. Frost we are able to print a photograph showing a quarter of the circumference of the sun obscured by the moon's disk, projecting from the edge of which are seen two gigantic prominences. This was taken by the expedition from Yerkes Observatory, of which Professor Frost is the director. The uppermost prominence shown, looking like the skeleton of some prehistoric monster, projects no less than 47,000 miles from the surface of the sun, a distance nearly six times the diameter of the earth. The exposure for this photograph, which was made by Miss Mary R. Culver, was twenty seconds, the sun being somewhat obscured by clouds. In addition to the prominence there is seen around the sun the light of the inner corona, this being the only portion which was bright enough to be recorded with the exposure given.

The astronomers are now busy studying the results which they have obtained, and drawing from them lessons which will in turn be used to plan new measurements to be made at the next eclipse.

A Generous Offer

A great many photographers have gone into the service and left their studios in charge of their wives, and in a great many cases, no doubt, these women need advice and instruction.

W. S. Lively, known by most every one in the profession as the manager of The Southern School of Photography, has seen this opportunity of doing a big unselfish thing and has grasped it. He proposes to throw open the doors of his school to the wives of photographers who have entered the Government service, and will give them two weeks of absolutely free instruction.

A program which would ordinarily cover three months will be condensed into a two weeks course of intensive training that will be of inestimable value to the woman who has been left with a photographic business as her support.
