At 9 p. M. the aurora began to fade, and at ten had nearly dis- 
_ appeared. At 104 P.M. the north gave indications of another 
aurora which occurred about 12 o'clock, nearly equal in splen- 
dor to the first, and still another occurred about 8 A. M. There 
were also auroras late in the night of the 30th and also of the

Aug. 28th, at 8 p. M., the appearance was that of a large lu- 
minous ring surrounding the zenith; but this form was very 
transient, the light becoming concentrated in the west. Between 
. M. there were two arches formed in the north, the 
first almost 80° in altitude, and the second about 40°. From the 
outer edge of the larger arch darted a succession of streamers or 
rays of light. At 84 15™ a perfect flood of light came up in the 
east, not in streams, but like the dawn of day, just before sun- 
nse, This appearance lasted about half an hour. At 9 P. M. 
streams of light radiated in every direction from a point about 
ten degrees south of the zenith, covering the whole eavens e€x- 
cept a space in the south. One broad belt of red light extended 
from near the zenith to the horizon at a point a little north of 
west.

Aug. 28th, the aurora began with floating irregular masses of 
auroral clouds in the north, which soon spread over the sky, ter- 
minating in a broad zone of light spanning the heavens from H. 
to W. and reaching to 20° south of the zenith, At8 P.M. many 
of the luminous clouds became distinctly crimson, with the deep- 
est hue near the horizon, At 8 15™ a distinct arch formed in

Aug. 28th, at 74. Pp. M., there were visible some splendid masses — 
of rose-colored light in the east and west near the horizon ; 
that in the west being nearly obscured by twilight. At 7% 45m 
a well defined arch passed south of the zenith, and all the sky 
horth of it was filled with light, radiating toward the pole of the
