EXPEDITION TO POINT P.AltROW, ALASKA. 389 



S, 18cS2, 1 <i. lit. ID 10..'!.') n. in. During the. early part, of the night' tin- sky \v;is cov- 

 ered with thick clouds, but at I a. in. these liad tliinnod away sulliciently to allow a few of tho 

 brightest shirs to bo seen, and broad bands of aurora, apparently in rapid motion, were observed 

 crossing the zenith from the \X\V.to BSE., spreading ont at the /.enilh to a trail some 40 in 

 width. Xo more aurora was observed until 9.10 a. m., when if appeared for about twenty minutes 

 in the form of a quiescent faint band across the xeuith from XW. to SIC., with tin- extremities lost 

 in the. haze. At 10.10 a. in. a band (brightness to 1) encircled the entire horizon, about 10 in 

 breadth, and resting on a dark baud of uncertain character (apparently hazy and stratus cloud) of 

 about the same breadth. At the same time a second similar band formed an arch intersecting the 

 tirst in the SIC. and X., with its crown at an altitude of about l.V. At about 10. .'5.1 the. sky clouded 

 over and no more aurora was observed. A magnetic disturbance commenced about 4, chiefly 

 aft'cctiug the horizontal force, which was hugely decreased. 



Xurrmlicr 9, 1382, 12.30 rt. m. to 7.30 a. m. At midnight no aurora was observed, but at 1 it 

 was already well developed in the form of a brilliant zone (2) from a point in Taurus in the ICSE. 

 Lori/on into Ursa Major and Leo Minor on the X. In the XIC. it did not reach lower than Gemini, 

 but extended also into Auriga. The zone consisted of three or four bands changing rapidly, bnt 

 not moving fast, forming sometimes whorls and streamers, and had spread into Perseus and 

 Andromeda at 1.10. At 1.17 it had faded a good deal, while two streamers started up in the , N. 

 and ICSE., meeting across the zenith, while a large whorl formed in Canes Yenatici. At 2 a. in. 

 the zone was still broader and contracted at the horizon, ran from Hercules in the X. to Taurus in 

 the SIC., mostly west of the zenith, occupying Pegasus, Cassiopeia, Oygnus, and Lyra, drifting 

 westward with rapid shooting and circling motion from SIC. to XW. It had faded a little at 2.10, 

 and was quiet, while quiet glowing banks of light replaced the 1 o'clock aurora. At 2.1 7 tho 

 western aurora had almost wholly faded, and the eastern developed into a regular arch, which 

 lost its regularity in a few minutes. At 3 a. in. the eastern zone had developed again from Orion 

 in ICSE. to Bootes in XX YV., narrowing at the horizon, in the middle stretching from Gemini up 

 to Ursa Minor (brightness 3), made up of sinuous bands, sometimes narrow, sometimes broad, 

 with some longitudinal motion from X. to S., spreading a little towards the W., and not so bright 

 at 3.17. At 4 there was a similar broad band or zone, but quiescent (2 to 3) from a point in Moiio- 

 ceros in the ICSE. through Orion, Taurus, Pegasus, Oygnus, and Lyra, to a point in Ophiiichus 

 near the NX'W. horizon, also spreading eastward in paler bands to Ursa Major, growing paler at 

 4.17. At 5 a. m. two parallel bands 4 s to D apart crossed th.e zenith from Taurus, through Per- 

 seus and Cassiopeia, to Corona (brightness 2), drifting slowly S,, with a rapid waving motion from 

 W. to E. At <> a band with a lew streaks above it, moving slowly to the S., stretched from Orion 

 through Gemini to Leo Minor. 7 a. m. saw a luminous band stretching round close to the horizon, 

 without motion, extending from Pegasus to Serpens. Haze then began to cover the sky, and soon 

 became clouds. A magnetic- disturbance, affecting the horizontal force, and to a less degree the 

 declination also, commenced at 2 a. m.. aud continued several hours after the end of tho aurora. 



Xni-cmlicr 10, 1882, 3 a. m. to 9.10 a. m. The sky was cloudy during most of the night. When 

 it cleared, at 3 a. m., no aurora was observed. A faint glow in the X. and X W. may have been 

 auroral. At 5.15 a. m. the clouds again broke away sufiiciently to show an arch from Taurus 

 through Pegasus to Lacorta from SIC. to SYV., partly hidden by clouds and haze (brightness 1 }. At 

 8 a.. m. the sky partly clouded again, disclosing a motionless baud from Orion to Leo, about 5-S 

 above the, horizon, showing through haze (brightness to 1). At !>.!() a. m. a few faint traces of 

 aurora were visible, through the haze and clouds. The magnetic needles were very slightly 

 affected. 



Xorcmhcr 12, 1S.S2, '> . i. to I/IMIH. During the early part of the night a furious storm of wind 

 and snow was racing, accompanied by a violent magnetic storm ati'ecting all three elements, which 

 lasted several hours after the aurora disappeared. Through a break in the clouds at 3 a. m. sin- 

 uous bands and streamers (brightness 2) were observed in the X.. in and near I'rsa Major. At 

 3.17 the sky was nearly clear, and sinuous bands from the XN"\Y. to 1CS1C. occupied mos; of the 

 western sky, the ends of the bands being lost, in haze, while an incomplete corona formed 1C. of tho 

 zenith (brightness L'). Accurate, observation was rendered impossible by the violence of t lie weather. 

 From this time, on the storm moderated. At 4 a. m. a whirling band ran up from Orion's belt in
