EXPEDITION TO POINT BARROW, ALASKA. 411 



paler and lower from Canis Minor to Orion's belt. At 1 a. in., there was a very faint arch 

 (brightness to 1) in the NE., with an altitude of about 10, through Leo, Coma Berenices, and 

 Bodies. Beneath was a well-defined dark segment. No more, was seen till 4.17 a. m., when them 

 was a band (brightness t) to 1) from N. to E. through Coma Berenices and Corona Borealis. At 

 3.17 a yellowish-green band (brightness 1) ran from Cyguus through Lyra, Ilercules, and Bootes. 

 Faint traces wen; observed at 7 a.m., while clouds prevented observation during the- rest of the 

 night. The magnetic needles were comparatively undisturbed up to about 7 a. m., when a consid- 

 erable disturbance began, which was still going on after daylight. 



January 3, 18S,">, ;5 <i. m. to 11.15 a. m. A bank of clouds lay along thu horizon all the early 

 part of the morning, and above them there seemed to be considerable glow, though no definite 

 aurora was seen till 3 p. m. (8.43 p. m. local time, January 2), when there was a broad hazy band 

 (brightness 1) somewhat sinuous near the horizon, stretching across the zenith from a point in 

 llydra in the ESE. to AquilaNNW. through Cancer, Lynx, Ursa Minor, Cepheus, Draco, and Cy gnus. 

 This band was about three times as broad at 3.15, embracing also part of Gcaiiini, all of Auriga, 

 part of Perseus, all of Camelopardalis, Cassiopeia, and Cepheus, and part of Draco, Laccrla, and 

 Sagitta. At 4 a. m. it had shifted west of Cassiopea, and was much broken, but a band rapidly 

 developed through Cassiopeia from the SE., waving gently. At 4.15 the whole sky was covered 

 with broad bands winding in large sinuous curves, one especially from Lyra in the N. up to Cassi- 

 opeia, then to Aries and the Pleiades and to Auriga. There was a bright, haxy, in-regular patch 

 of large extent iu the NW. The brightness of the whole was 1 , and all shifted slowly, with gentle 

 undulations. The intensity of the magnetic needle had been low for over twelve hours, and Ihe 

 horizontal force needle was now agitated. At 5 it had subsided into two broad, quiet bands, 

 Starting from Pegasus (brightness 1), one going S. to Orion, and the other N. to Hercules. At <> 

 there were only traces of a band from SE. to \V., at an altitude of about 45. At 7 a broad, 

 yellowish-green band waving rapidly from W. to E. (brightness 1 to 2) ran from Pegasus through 

 Andromeda, Cassiopeia, Camelopardalis, Ursa Minor, Ursa Major, and Canes Venatici. No more 

 aurora was seen till 11.15 p. m., when there were faint traces in the E. The intensity continued 

 low, being consideraly disturbed at 9 a. m. 



January 4, 1883, 3 a. m. to S a. m. At ."> a. m. (10 p. in. local time) there was a very faint ver- 

 tical streamer about 20 long running from near the horizon ESE. This was prolonged at 3.15 

 into a narrow band (brightness to 1) from Hydra, through the top of Leo, Leo Minor, and Ursa 

 Major, then burning very pale through Draco and fading in Lyra YV. of </. Lyr:;-. At. 4 traces of 

 the band were perceptible a little higher, and at 4.15 the traces crossed the zenith. At 5 a yellow 

 ish qnief band (brightness to 1) ran from Cygnus in the NNW. through Lyra, Hercules. Corona 

 Borealis, Bootes, and Coma Berenices. At a. in. a broad, motionless band (brightness 1) extended 

 through Aries, Taurus, Orion, and Canis Minor. After this traces only were noticed in thcNE. at 

 7 and from the NW. to W. at S. The magnetic intensity continued low, especially the horizontal 

 component, but there was no disturbance. 



January 5, 1883, 12.15 <i. in. to 5 a. in. There was a Taint glow in the N E. at 12.15 a. in., which 

 had developed at 1.15 into a regular, narrow, quiet arch through the haze in the NE. (brightness 1), 

 with its extremities bearing ESE. and NNYV. and its crown at an altitude of about .'HP. The stars 

 in the neighborhood were obscured by a bank oi' haze. There was also a band of the same bright- 

 ness beginning in a bank of haze in the NNW. and running through Lyra, Draco, Ursa Minor, 

 Camclopardalis close to ,'* Auriga.' and Gemini, fading in a few minutes. At 2 a. m. (here were two 

 sets of auroral bauds starting from nearly the same place in the haze in the ESE. and NNW., one 

 a broad band, hazy and twisted, waving gently through Lyra, Cygnus, Cassiopeia, Auriga, and 

 the western side of Gemini and Canis Minor, and the. other a zone of three or four quiet bands in 

 the NE., the highest through Ursa Major, and the lowest through Leo. The brightness of the 

 whole was 1. At 2.15 the western band was gone, except its NNW. end, and the zone had in- 

 creased to six or seven bands. At 3 a. m. a very broad hazy zone (brightness to 1) covered 

 nearly the whole of the sky. The starling points were hidden in the ESE. and NNVV., and tho 

 eastern edge readied the hazy clouds close to the horizon, while the western passed through Cyg- 

 nus, Andromeda, Perseus, Taurus, the upper part of Orion, and Monoecn. It was very much 

 faded at 3.15, though the eastern edge was growing bright. At 4 only that part of the zone which
