were unable to unbar the door owing to the pressure of 3 feet of 
fluid, and escaped by climbing through the window and wading to 
higher ground. 
Below Annagh Bridge, the force of the flood was less felt. At 
Barraduff Bridge, ‘‘ Six-mile”’ Bridge of the Ordnance map, where 
the Ownacree joins the Beheenagh river, the Ownacree is 20 feet 
wide, and the flood rose 8 feet; below the jsanction the stream is 
30 to 50 feet wide, and the flood rose 6° “feet; at “Six-mile ” 
Bridge it rose to the top of the arches, 10 feet above its normal 
level; at the bridge two miles below Headford, the level of the 
flood was about 4 feet above the stream, and finally at Flesk Bridge, 
near the Lake of Killarney, one foot. 
The flood attained its maximum height during its first great 
outburst in the dark hours of Monday morning. At daybreak, 
the roaring flood of black fluid, bearing on its surface huge masses 
of the lighter crust of the bog, had already become confined to the 
central portions of the valley, but still ran across the road and 
over the site of Donnelly’s house. The flow, which continued with 
constantly diminishing violence for the whole of Monday, was not 
regular, but intermittent, swelling and diminishing as fresh portions 
of the bog gave way, and slid downwards into the torrent. Every 
fresh outburst was accompanied by loud noises, likened by 
bystanders to the booming of big guns or the rumbling of thunder. 
Over the sides of the valley the settlement of the peaty part of 
the fluid had already taken place, and, as drainage continued, 
increased somewhat in consistency. ‘The disruption of masses of 
bog continued at intervals down to Friday, January Ist. When we 
visited the scene on Saturday, January 2nd, the flow had lost its 
torrential character, but a turbid stream, many times increased 
beyond its usual volume, occupied the river bed. Mr. James 
Barbour, who visited the place on Saturday, January 8th, reports 
that one could then have stepped across the stream, so that by 
this time it must have shrunk to nearly its usual size. 
The Bog before the outburst.—The district in which the bog is 
situated forms the southern portion of a high and undulating area 
of Coal-measures, generally bog-covered, and attaining a height of 
over 1200 feet, some. miles to the north-west. That part of the 
bog in which the outburst took place is about 750 feet above the
