N.E. by N. magnetic, at an altitude varying from 8° in N.W. by N. magnetic to 12° in N.N.W. 

 magnetic and to 4° in N.E. by N. magnetic. - 28° • 2 F. Calm, cloudless sky. 



lOh. p.m. Faint yellowish streak, extending from an altitude of 10J° to 25° in N.W. l)y N. 

 magnetic. Most brilliant rays in N.N.W. magnetic, as bright as a star of 3rd magnitude. 



Midnight. Bright rays of light in W. magnetic, extending from 8° to 18° in altitude, and 

 from W. i N. to N.W. by N. magnetic, in the form of an arc, getting fainter towards the N.W. 

 by N. (magnetic) end, which was at an altitude of about 25°. 



April 9. — Oh. 15m. a.m. The above had all disappeared, except for a broad streak in W. ^ N. magnetic, 

 from an altitude of 9° to 15°, where it was very faint. Temperature, -27° F. Wind N. by 

 E., 1. Cloudless sky. A very faint arch, extending from N.W. by N., altitude 8°, to N.N.E. 

 magnetic, altitude 20°, just discernible. A faint patch bearing N.E. by E. magnetic, at an 

 altitude of 5°. 



2h. a.m. Faint streamers to an altitude of 12°. Very faint arc, extending from N. 20° W. 

 (magnetic) to N.W. by N. magnetic, at an altitude of alrout 15°. Cloudless sky. -26" -5 F. 

 Calm. 



6h. a.m. Broad faint streamers bearing S. (magnetic), altitude 6° to 9°. - 22° F. Light 

 Ci.-s. cloud bearing N. by E. true. Wind N.N.E., 1. 



April 11. — 2h. a.m. A steady streamer maintained, stretching from Harbour Hill to almost overhead. This 

 streamer has a concave side to the W., and lies due N. and S. The western edge is most defined 

 and the sky appears darker immediately adjacent to this edge than in any other part of the sky. 

 No sign of aurora from April 11 to 18, due, perhaps, to bi-ight moonlight making these faint 

 displays invisible. 



April 19. — lOh. p.m. Auroral are, extending from W. 5° N. magnetic to N.E. magnetic; apex 13° above 

 horizon, and a little to N. magnetic of Observation Hill. Motion slow, streamers short, viz., from 

 1° to 2°, and brightest to N.E. magnetic. Intensity of brightest patch = star of 3rd magnitude. 

 Wind E.S.E. true, 2-3. Temperature: -15°-3F. No clouds. Fairly bright moonlight. Arc 

 had entirely disappeared at lOh. 10m. p.m. 



llh. 20m. p.m. A similar, but fainter, arc formed. Amplitude same, but altitude of apex 

 had increased to about 30°. Nothing visible at llh. 30m. p.m. 



Midnight. Very faint auroral clouds around zenith. Moonlight veiy bright. Barometer 

 falling somewhat fast and temperature rising. 



April 20. — Ih. 30m. a.m. Two faint streamers in N.,each about 10° in length and about 4° apart, starting 

 from 5° above horizon. 



2h. a.m. Faint auroral patches near zenith. 



lOh. p.m. Extremely faint auroral arc, extending from N.E. by E. magnetic to N.W. by W. 

 magnetic. Apex N. liy W. magnetic, altitude 11°. 



Midnight. Faint streamer about N.E., rising to 70 from horizon. 



April 21. — Midnight. A very perfect arc, extending from horizon at S.W. true to N.E. true. Greatest 

 altitude about 30°. Formed entirely of vertical rays. Fairly brilliant in the N.E. Temperature 

 - 40° F. b. Calm. 



April 22. — 2 a.m. A band, with a twist at the zenith, made a complete arc from the S. horizon to the 

 N. horizon (true). Temperature, - 37° F. b. Calm. Intensity moderate. 



April 23. — 2h. a.m. Faint bands of aurora, extending from zenith down to top of land, bearing N. 20° W 

 magnetic. Temperature, - 15° F. Wind E. by N. true, 2-3. be. Cu. 1, N.W. magnetic. 



4h. a.m. Bright and broad streaks of auroral light, altitude 10°, bearing N. 80° W. magnetic 

 and N. 75° W. magnetic. Faint band bearing W.S.W. magnetic, extending from altitude 8° to 15°. 

 Temperature of air, - 13° -4 F. Wind E. by N. true. Cloud, Cu. 2, N.W. by W. magnetic.
