38 SCIENTIFIC RESULTS OF ZIEGLER POLAR EXPEDITION 



in south and zenith; 2:20:42, very light wind, faint aurora in south, cross still in moon ; 

 2: 20: 52, aurora from zenith to east and west ; 2:21:12, faint aurora in west, dark clouds in 

 east and west ; 2: 21 : 38, aurora has disappeared, partly cloudy in east, wind light. — 3: 16: 00, 

 revolver not taken to hut ; high wind. — 4: 20: 00, revolver not taken to hut, aitrora in north ; 

 4: 20: 46, passage to vestibule drifted in so much thai observer cannot very well observe weather 

 conditions or aurora. — 6, preparations for sledge journey being completed, no time to carry 

 out observations this day. — 7, sledge party left this A. M. — 9:06: 26, observations interrupted 

 by failure of light. — 13:02:46, magnet vibrating up aud down; 13: 04; 02, daylight begins; 

 13:06:36, increasing but stopped a moment at this reading. — 16:03:42, daylight begins; 

 16:08: 18, magnet taken out and replaced (not being level in stirrup either way); 16: 12: 00, 

 clear overhead, light fog on ice field; 16: 12: 32, scale increasing almost imperceptibly; 16: 16: 32, 

 observer can see no cause for this jump of needle; 16:21: 18, daylight ends; 16:22:22, sky 

 clear; 16:22:54, aurora from northeast to zenith increasing in intensity; 16:23:10, very 

 faint aurora in zenith and southwest. — 17; 16: 00, instrument removed from pier in morning to 

 clean grooves in which foot-screws set. — 18: 22: 00, wind velocity about 20 miles an hour, sky 

 hazy. — 20:00:00, instrument cleaned in morning, revolver not taken to hut; 20:03:28, day- 

 light begins. — 21:11:36, revolver not taken to hut; owing to 60 to 70 mile wind hut could 

 not be reached before 11:30. — 22: 12:00, revolver not taken to hut; 22: 14: 21, checked mag- 

 net with adjusting pin. — 23:00:00, revolver not taken to hut; 23:00:06, magnet checked 

 with adjusting pin; 23:03:18, daylight begins; 23:05:30, wind ceases; 23:06:46, wind in 

 gusts; 23:08: 58, light northerly wind, sky cloudy; 23: 15: 54, wind from northwest; 23:16:04, 

 trouble with light cause of delay in observations; 23:22:06, sufficient light to see dwelling 

 distinctly through flying snow; 23:23:18^ daylight ends. — 24:16:00, revolver not taken to 

 hut. — 25:24:10, fiber broke. — 26:11:30, put in four new fibers.— 27:02:46, daylight 

 begins; 27:05:22, decreased to this, stopped, and then increased. — 28:08:00, fibers found 

 broken; three new fibers put in and observations started as soon as torsion taken out; fibers 

 again broken during intensity observations and replaced by four new fibers at 23 : 00. — 

 29:13:54, scale increased to 57*.4 at 13:55.2. — 30: 00: 00, sky partly cloudy, north-north- 

 east wind of velocity 48 miles per hour; 30: 00: 12, observer found tin box in pocket and put 

 same away where would not affect instruments; 30:06:00, wind decreasing; 30: 12:41.7, scale 

 reached 28*.7, decreased steadily, stationary for a moment at i6*.8, decreased to lo^.o after 

 reading at 12: 46, then increased to 18^.7, and then oscillated as shown at 12:50; 30:15:04, 

 scale decreased to ii*.6; 30: 15: 54, magnet vibrating up and down; 30: 20:02, scale increased 

 to 22*.9, stopped, decreased to 22^.1; 30: 20: 10.6, scale increased to 51^.7; 30: 20: 38, increased 

 to 49*.i, stopped, then increased to 5I^9 at 20: 38.9; 30: 20: 44, scale decreased to 38''.7, stopped, 

 then decreased to 34^.9 at 20:44.2; 30:20:46, then increased to 36^.2; 30:21:13, scale in- 

 creased to 26^2; 30:21: 14, decreasing to 28*. i; 30: 21:40, reading 6^4 estimated; 30:21:46, 

 daylight ends. 



April, 1904. — 1:20:00, revolver not taken to hut; 1:20:06.5, decreased to 28''.o. — 

 3:00:00, revolver not taken to hut; 3:00:36.4, scale increased to 78^.1; 3:00:38, scale 

 decreased until passed out of field of view; 3:02:26, daylight begins. — 4:08:00, revolver 

 not taken to hut ; 4: 10:58, scale increased to 72*.9. — 5: 12:00, revolver not taken to hut.— 

 6:02:00, sky clear, calm; 6:16:14, instrument slightly out of level. — 7:16:00, sky clear, 

 calm. — 8:20:00, sky clear, light north wind. — 10:02:08, scale decreased to 65*. 2 ; 

 10:03:20, scale increased to 52\2 ; 10: 05:44, reading 78^7 estimated.— 11:08:00, northeast 

 wind of 40 miles per hour velocity. — 12: 12: 00, revolver not taken to hut ; 12: 12: 08, magnet 

 oscillating up and down. — 13:00:00, light southwest wind; 13:07:00, wind south, hazy, 

 light snow; 13:09:12, from quiescence scale decreased; 13:16:59, scale now ao^.e. —
