EXPEDITION TO POINT BAREOW, ALASKA. 413 



rapidly from W. to E., slightly tinged with green and rose, and varying in brightness from 1 to 2. 

 Only a few traces overhead were left at G, and for the next three hours the sky was clouded over. 

 though (here were traces in the S. at 8. It was clear again at 10.17, and an irregular white quiet 

 band was seen running from SE. to NW., through Draco, Ursa Major, and Canes Venatici. There 

 wiis a broad streamer in Lyra in the E. about 30 long, and a bright patch in the NW. in Triangu- 

 lum, Aries, Taurus, and Perseus. At 11.17 the SW. half of the sky was covered with white quiet 

 bands converging in the E. and W. (brightness to 1), and there were also streamers from Sagitta 

 and Cygnus in the NE. to Triangulum in the NW. This was accompanied by a violent disturb- 

 ance, the horizontal force being too low to read, and the declination rising over two degrees, with 

 large increase of the vertical component of the force. The display at 5 was accompanied by a 

 disturbance afl'ecting chiefly the horizontal force. After 11.17 the sky became permanently cloudy. 



January 1 awl 8, 1883, 10.15 p. m. to 1 a. m. At 10.15 there was an arch of lino short streamers 

 in the NE. with its extremities bearing NW. by NE. by S., and an altitude of about 30. This 

 faded, and none was seen till 12.15 a. m., when there was a zone, with its starting points in Orion 

 and Serpens. Of these bands two were close together and parallel, passing nearly overhead, 

 and the third through Serpens, Hercules, Cygnus, and Pegasus; thence to Orion it was broken 

 into streamers. In Serpens and Bootes the baud had the curtain form (brightness 1). The zone 

 form continued at 1 a. m. (brightness 1), with its starting points in Mouoceros ESE. and llercules 

 NNW. The main portion (three bands, two narrow and one broad, considerably twisted) ran 

 through Lyra, Draco, Cepheus, Ursa Minor, Camelopardalis, Auriga, Gemini, and Cain's Minor, 

 and a paler band passed through Canis Minor, Lynx, and Ursa Major, then fading towards the 

 N. This eastern band was brightest at 1.15. At 2 the starting points of the zone were just below 

 a Leonis E. by S. and near ? Aquihr NNW. From Leonis to Monoceros ESE. it was horizontal, 

 and the eastern edge then passed through Cancer, Gemini, Auriga, Camelopardalis, Ursa Minor 

 (AV. of Polaris), Cepheus, Draco, and Cygnus, and the western through Canis Minor, Orion, Taurus, 

 Aries, Triauguluru, Andromeda, Pegasus, Vulpecula, and Sagitta (brightness 1 to 2). The hori- 

 zontal portion was gone at 2.15. At 3 a. m. bands and streamers (brightness 1) approaching the 

 curtain form, especially in Leo, filled the NE. sky from Leo ESE. to Hercules NNW. and from near 

 the horizon to Ursa Major. This was broken and paler at 3.15 and a pale streamer was shooting 

 up from the NNW. ending in Cassiopeia. The sky was half overcast with hazy clouds at 4, and 

 at 4.15 traces were visible through the clouds in the N. At 5 there was a pale yellowish, band, 

 (brightness 1) in the SW. from Monoceros and Canis Minor through Orion, Taurus, and Aries 

 The sky then became more cloudy and traces only were observed in the S. at G a. m., and in the 

 NE. at ,7 a. m. The sky then became wholly obscured. The magnetic needles were comparatively 

 quiet, being slightly disturbed from 3 to 8 a. m. and again from 12 m. to 2 p. m. 



January S and 9, 1883, 10 p. m. to 2.12 p. m. There was a glow in the NE. at 10 p. in. which at 

 10.15 had developed into a faint arch, with its extremities bearing N. and E. and its crown at an 

 altitude of about 2<P. This was gone at 11, but at 12.15 a. m. there was a patch of hazy light ia 

 the X. in Canes A'enatici, Coma Berenices, and Ursa Major, and a line of faint streamers through 

 Corona Borealis, Bootes, Ursa Major, and Lynx. At 1 there was a slightly sinuous arched band 

 (brightness 1) in the NE. from Monoceros ESE. through Canis Minor, Cancer, the top of Leo, 

 Leo Minor, t ho lower part of Ursa Major, Canes Venatici. Bootes, and Corona Borealis to Hercules 

 in the NNW. The northern end appeared to be breaking into streamers. These had developed 

 at 1.15 into a bunch shooting up into Draco, and the. band had split into two. At 2 a. m. these 

 started from lloicules in the NNW., three or four diverging bands stretching across the eastern 

 sky growing paler towards the SE. ; one through Lyra, Ursa Minor, Ursa Major, and Lynx; one 

 Through Corona Borealis, Bootes, ( 'anes Venatici. I.co Minor, and Leo, and one or two between this 

 and the horizon with traces of a band which was developed at 2.15 through Cygnus, Cepheus, 

 Cassiopeia, Camelopardalis, and Auriga to Gemini, while the eastern bands were fading. The 

 sky tiit-i! iiecamt' overcast. Traces of a zone across the zenith \verevisiblethroughthehazyclouds 

 at '<, and similar traces of a band at. 4 a. m., which appeared to be moving AV. Traces were seen 

 again in the NK. at <J a. m. The sky was partially clear at 8.17, and a quiet band (brightness 1) ran 

 from Andromeda through Lacerta, Cygnus, Draco, and Bootes. The sky cleared off' permanently 

 after this. At !).17 there was a broad, quiet, white band (brightness 1) along the southern horizon
