the barometer, was a series of most extraordinary fluctua- 

 tious; tlie disturbance would suddenly appear at any given 

 station, and after a few hours be scarcely perceptible, only 

 again to appear at this or some other station. A diagram 

 showing these fluctuations is interesting. The center ap- 

 peared for a time to be over the interior valleys of Califor- 

 nia, and not great in depth, and it was only upon consulting 

 ship reports that it was found that the eye of the storm was 

 far to the westward. This center appeared first upon the 

 coast about 3 a. m., January 20th, off Point Conception, 

 where the roughest weather was experienced. A few hours 

 later it was reported off the mouth of the Columbia Kiver. 

 From 5 to 8 A. M., about 175 miles southwest of San Fran- 

 cisco, the Zealandia was in a southeast and southwest hurri- 

 cane, with the glass at 29.23. The barometer, about the 

 same time at San Francisco, was 29.31 inches; at 8 a. m., at 

 Cape Mendocino, the barometer fell to 29.15, with the wind 

 a hundred miles per hour from the S.E.; at noon it was 

 29.06, with the wind from the southeast and blowing with hur- 

 ricane violence, carrying away the anemometer, after which 

 accurate observations were interrupted for a few hours. 

 At the same time the wind was southwesterly at San Fran- 

 cisco, blowing 42 miles, but at Point Lobos, the south head 

 of Golden Gate, six miles away, it was 96 miles an hour. 

 The cyclone was off the coast of Oregon at 7 A. M., as shown 

 by a pressure of 29.17; but by the following morning, the 

 21st, at 4 A. M., the pressure had risen, and the cyclone had 

 completely vanished from the charts, and by 12 M. the 

 isobar of 30.20 passed from Washington Territory through 

 Oregon down to the center of California and out near San 

 Luis Obispo. But one other isobar (30.10), drawing isobars 

 for every tenth of an inch, appeared on the chart, and this 

 enclosed northwest Washington Territory. The next morn- 

 ing (22d) the cyclone reappeared at the mouth of the Co- 

 lumbia River, here also carrying away the anemometer. It 

 again subsided, and burst in once more the same day at the
