Peaks on the Sound Give Forth Smoke
A HUGE RENT ALSO APPEARS
Citizens of Whatcom Disturbed by an Earthquake Shock Earlier in the Day.

Whatcom, Dec. 11. - [Special.] - One of the Twin Sister, north of Mt. Baker was observed at 11:30 a.m. emitting a huge volume of smoke, which arose apparently to the height of a thousand feet. The smoke was soon lifted to the north and disappeared about 2:30 p.m. A column of smoke also arose from Mt. Baker, and other mountains showed the same phenomena. A rent was observed in the main Sister which has never appeared before, and which was apparently a quarter of a mile long, running from the top of the mountain toward the base. The mountain has never been surmounted, the top being a precipitous mass of chrome iron and about 9,000 feet high.
In the early morning a distinct earthquake shock was felt. William Shears, who is a well-known citizen and who lives on J street, was disturbed at about 5 a.m., as was also William Saunders, who lives at the corner of J and Fifteenth streets, and many others. At about the time of the first eruption, the mayor and his family were likewise startled by a distinct shock.
