ANNOUNCE WHAT, WHEN, AND WHERE OF TODAY'S ECLIPSE

8 o'clock.--Moon will make its first indentation on the sun's rim. This nick will grow quite speedily as the moon moves between the earth and the sun.

8.30 o'clock.--Sun will be half obscured with darkness approaching very speedily, much in the same manner as night approaches.

9 o'clock.--Sun will be a very thin crescent. The atmosphere will look stormy. Observers should watch for shadow bands on sides of white buildings and on the snow. The thin crescent of the sun breaks up into glittering points of light, which astronomers have dubbed Baily's beads.

Look quickly towards the west. Rushing from the horizon the shadow passes from west to east at a speed of two thousand miles an hour.

9.11 o'clock.--Sun now eclipsed in path of totality. Stars now clearly visible. After a minute or so the reaction will set in and the moon will pass from the sun's face.

10 o'clock. Mid-year examinations begin.
