cottage 10 feet deep, rose over the Belfast-Londonderry coach 
road, crossed it with a width of 300 yards, and poured over the far 
bank in a cascade, and continued down the valley till it reached 
the River Maine, which it dammed temporarily, and killed all the 
fish. The flow into the Maine did not cease till Sept. 28. The 
deposited area of bog was three-quarters of a mile long, and 200 to 
300 yards wide, with a maximum depth of 30 feet. The place 
where the bog had swelled up 30 feet, afterwards sunk 20 feet below 
its original level, and a small pool occupied the hollow.’

cutting, which was from 12 to 15 feet in height. A very rapid — 
flood of peat and water poured forth, bearing on its surface — 
large masses of the crust of the bog; it rose 10 feet over Baslick — 
Bridge, and left a deposit of peat, which covered 165 acres of low — 
ground and extended for some 6 or 7 miles down the valley of the — 
Suck. A valley was formed in the peat bog half a mile in length — 
and 20 feet deep.
