glow in the E. (true), and very faint streamers from nearly all parts of the heavens, excepting 

 the W. true. 



4h. a.m. Very faint streamers in N., N.E., S., and N.W. true, reaching up to about 50° 

 altitude, and disappearing about altitude 20°. 



July 6. — 2h. a.m. Faint aurora for a few moments. A semi-arc of streamers S.E. to E. (true), crest 

 of arc S. true, where the longest and brightest streamer was 20° to 40° in altitude. 



4h. a.m. Faint streamers in the E, and S. true, strongest in S., 20° to 40" in altitude. 



6h. a.m. Luminous aurora clouds in S. (true) in a somewhat serpentine form, rather bright 

 just for a few moments, a few very faint streamers in the E. true. 



8h. a.m. Single aurora beam in N.W. (magnetic), altitude 20°. 



Midnight. Faint arc, extending from Observation Hill to Bluff, altitude at brightest 

 part 10°. 



July 7. — 2h. a.m. A few faint beams shooting up from S.W. by W. (magnetic) to the zenith ; 

 intermittent and lasting a few seconds only in each case. 



5h. a.m. Faint auroral curtains, extending from Observation Hill to S. true, altitude 

 generally 30°. 



Similar phenomenon at 6h. a.m. 



8h. a.m. A faint semi-arc of more or less diffused vertical beams, rising from N.N.W. 

 magnetic to a height of 30° over W.N.W. (magnetic), where it was lost. Outside this was a 

 fainter half-arc, rising from N.E. (magnetic) and ending at an altitude of about 20° over N.N.W. 

 magnetic. Intensity faint. Wind nil. Temperature, - 24° F. No clouds. 



6h. p.m. Bright auroral glow from E. to S.E. true, at times forming bright arc, but generally 

 diffused glow, altitude 7°. - 14° -5. E, 1-2. 



8h. p.m. Faint arc of streamers from E.N.E. to S.E. true, altitude 10°. Light E. airs. 

 -11° F. 



Midnight. An arc of luminosity, no beams apparent, stretching from a height of 10° at 

 E.N.E. magnetic to 20° at N.N.W. magnetic. Vertical breadth of arc from 6° to 8°. Intensity 

 very faint. - 19° F. Calm, no clouds. No marked darkness beneath and in the arc. 



July 8. — Time 6h. a.m. E.xtensive aurora of vertical streamers, arranged chiefly in pairs, some very broad 

 and very long, length from 40° to 60", and extending up to the zenith at N.W. (magnetic), otherwise 

 arranged in an arc, quickly shifting upward and being replaced by another from below, so that 

 in the N.E. (magnetic) there were sometimes the extremities of as many as four arcs in view at 

 once. Geneial intensity faint. Brightest streamers in E.N.E. (magnetic) very low down and short, 

 to W. magnetic high and long, S.W. magnetic long, but base touching hills. There were no true 

 curtains, and instead of a dark appearance beneath the arc there was more inclination to a faint 

 luminosity, which may have been thin mist. Calm. Temperature, - 12° '5 F. No clouds. 



July 10. — 8h. a.m. Irregular arcs formed of vertical streamers, from horizon in N.E. magnetic to W., where 

 altitude was from 10° to 20°. In N.W. by N. magnetic one of these arcs was moving fairly 

 rapidly to the right. The upper part of the curtain was from 30° to 40° above the horizon when 

 it had swung round to face the observer. Intensity variable, bright at times, movement of 

 curtain visible. Temperature, - 8° F. Calm, clear sky, no clouds. 



At 4h. 27m. p.m. fairly bright aurora glow, just showing upon hills from W. 5° N. to 

 N.W. magnetic. Only lasted a few minutes. No clouds. Wind E., 2. - 4° F. 



July 12. — At 6h. a.m. faint curtain from N.N.E. (magnetic) through 10° of amplitude, altitude 10° to 15°, 

 light fading in upper part, two or three vertical shafts about N. Others N. 40° W. to N. 70° W. 

 (magnetic), altitude 30° to 45°, light fading in altitude. No part of phenomenon exceeding 4th 

 magnitude star in intensity. Wind E.N.E., 4-5. 



At about 8h. 20m. a.m. observed disconnected curtain of aurora from N.N.E. to N.W.
