was cloudless at the time, the weather clear and agreeable, with 

 what mariners would call a " stiff breeze." The wind prevented 

 the effect of the earthquake from being noticeable on the river, 

 although some observant persons say that the surface of the water 

 appeared darker than its ordinary color while the concussion 

 lasted." 



The A^ews adds the following : — '•' The shock was so sudden that 

 to those who were within doors it appeared as if the chimney-wall 

 or roof of their own or their neighbor's house had given way and was 

 tumbling down. At the Artillery Barracks, the men ran from their 

 rooms into the square and up towards the magazine, fully convinced 

 that another explosion had taken place. On the citadel, too, 

 where we are told the shock was most violent, the men ran in ter- 

 ror from their bomb-proof rooms into the square, and crowded the 

 ramparts to see where the explosion had occurred. 



" We learn that in the ship-yards at St. Roch's, the ships on the 

 stocks waved to and fro. Some persons say they distinctly saw 

 the river rise in some parts to a height of nearly ten feet, and that 

 it receded almost immediately." 



Mr. Herbert Williams writes to the Quebec Chronicle as follows, 

 from Harvey Hill Mines, under the date of Thursday April 21 : 

 " At 1.15 p.m., yesterday, a smart shock of an earthquake was 

 felt in this district, lasting from ten to fifteen seconds. It was also 

 perceived by some of our miners, who were at the time working 

 at a depth of 180 feet below the surface. The undulation at 

 this place, as nearly as I could judge, seemed to travel from south- 

 west to northeast, the wind blowing at the time from the north- 

 east. At 6.40 p.m., we had a brilliant flash of lightning without 

 its usual accompaniment of thunder ; the sky at the time was 

 perfectly clear, the wind blowing strong from the northeast. As 

 yuo will, I doubt not, receive many communications from different 

 parts of the Province, it may be interesting to learn the time of 

 its appearance at different places. Hence I send you the above 

 facts of its occurrence here."
