Eruption of Long Lake and Mud Lake, in Vermont. 47 
depth, so that every trace of the original bed of Barton River 
disappeared, and the river was left to choose for ‘itself a new 
bed, many feet below the old one in the bottom of the gulley. 
In some instances the excavation was narrower, in conse- 
quence of huge rocks on both sides, which the torrent could 
not move ; but in such cases, amends were made in its great- 
er dep’ ere an immoveable rock was found on 
- side only, it usually altered the course of the torrent, without 
materially diminishing its breadth. Wherever any such ob- 
struction made an eddy, by stopping mome ntarily the tor- 
rent’s progress, the effect was still observable in deposits of 
sand, immediately above the obstructions, varying in depth 
and extent with the time during which the water paused, and 
the surface which it covered at the moment. Some of these 
are an acre or more = extent, and 20 feet indepth. In these 
eases there was usually a deposit of the floating forest trees. 
At Keene torntte it not only swept away the grist-mill and 
saw-mill of Mr. Wilson, with the mill-dams, but the 
sites, with all the ground beneath them for many feet, as wellas 
bed of the river by which they had been imperfectly sup- 
plied. A man in one of the mills, hearing the noise of the 
mepeeseene flood, ran to save himself; and had_ but just es- 
from its ast as it went by. His horse, tied at a post 
near the mill, was swept away, and was afterwards found a 
great distance below, literally torn to pieces. 
About a mile below the mills, the torrent entered a more 
level country; where the river had been wont to glide 
ough a broader valley, and was generally bordered with 
flats or intervals of some rods in width, covered with forest 
trees. Here this moving mass of trees, ‘earth and water, ex- 
panded itself as the country opened, and with the velocity ace
