Reference #11928:
At Eboulements ten houses were completely thrown down, besides that of Mr. Clement, M.P.P., for Charlevoix, and Dr. Laterriere. Two children are reported killed in this parish, but a letter from there today does not mention the fact. It appears that all the houses within an area of a mile, in this locality, were more or less damaged and there would have been great loss of life had not the people hurriedly quitted their residences. The two-story stone building used as an hotel at the Eboulements wharf has been almost levelled to the ground.
At St. Paul's Bay, one half of the church and seventeen houses have been prostrated. At Isle-aux-Coudres, five houses were thrown down. In rear of St. Paul's Bay and Eboulements, small mountains have been lifted up and their shape changed.
Near Cape Trinity, a mass of rock more than four hundred feet in length, has been detached from lofty banks and precipitated into the river Saguenay.
A letter received in town this morning from River Ouelle, says the earthquake did much damage there.
