 The following account of this wonder> full phenomenon, as seen by admiring hundreds in this city on "Wednesday eve ming of last week, is from the pen of Prot! Olmstead of Yalo College, published in the Palladium.

 We were visited last evening, by | one of those remarkable auroral arch> es which seldom occur other than once in a generation. Many persons, however will recollact lhpt a similar phehomcnon exhibited itself on the 18th !, of August, 1897. Both occurred nearly at the same time in the evening, and their appearances greatly rrssm5lcd each oth> CT.

 Our attention was attracted early in the evening to that twilight illumination of the sky which is the usual precursor of the aurora. When near the northern horizon there is seen dense bank of milky vaper, either with, or without smoky cloud ut its base, We may usually expect ore of the more splendid eXhbi- lionS of lha aurora. In the present case, the proguoStics were such as 10 warrant lhe expectation of an unusual, although not one of the most magnificent display The arch began 10 form about quarter before ten o'clock. Al 9h 54m it presen- ted grand spectacle, spanning the heav- ems from cast 10 west, crossing the merid ian little north of the !nlh. Its color was of a pure milk white. Its form was that ofa bro i'd zone over head, but ta- pe,ed towards either extremity, and bent northward on both ends, neither of them reached to the horizon. At the distance of , degrees from the northern margin appeared striking and beautiful feature consisting of offset's, or short parallel ridges, a, right angle, to tue side of the arch.

 Al 10 o'clock, tic southern marGin of the arch skrtel on the bright star POiIux, in Geminii, whiI., on the east its centre covered Arciuru, and its summit touched the bend of the eiccle in Leo. It did not therefore, form great circle of the sphere, nor was it as these arches are sometimes reported to be, perpendicular to the magnetic meridian. The whole moved slowly to thn south, until Ion l2n when it broke up into transverse ridges, rsSem5ling parallel drifts of snow, and soon afterwards vanished. Several faint attempts were mad. 70 form itself anew, but the attention was drawn from thosc ridges to the An'nral Waves which ot about baIfpast 10 began 70 flow up from the northern sky towards the magnetic pole of tho dipping needle few deg rees southeast of the zcnl,h. These con- tinued for half an hour, ia surprising degree-aficr which lhe aurora subsided in,o the original twilight appearance.

 Ii as W. sincerely hope, precise obser- va,ions were mrdo upon this arch, in diff fercnt places, tracing it's position by the fixed stars, they should be reported in the pApers-,hcy vii! furnish valuable da> ia for estin.gtiAg the height of the aurora above the surface of the earth. Our pres ent impression s that this was very far hove ,he clouds. and was seen over erea, ext, al O. county. U.
