Tus daily newspapers of Tuesday, the 29th of December, 1896, 
announced that, in the early hours of the morning of the previous 
day, a bog, situated at the head of the Ownacree valley, seven 
miles N.N.E. of Headford, near Killarney, had burst, and dis- 
charged a fluid mass, which, pouring down the valley of the 
Ownacree, had devastated the surrounding country in its course. 
Without loss of time the Royal Dublin Society appointed a 
committee, consisting of Professor W. J. Sollas, Mr. R. Ll. Praeger, 
Dr. A. F. Dixon, and Mr. A. D. Delap, to investigate and to 
report on the phenomenon. The committee left Dublin on the 
afternoon of Friday, January 2nd, and devoted Saturday, Sunday, 
and the early part of Monday to the work. They desire to 
acknowledge in this place the kind assistance rendered them by 
Mr. Maurice Leonard, 3.p., acting for Lord Kenmare, on whose 
estate the bog is situated. 
The following summary comprises the results of their observa- 
tions and inquiries, supplemented by information derived from 
the full accounts which appeared in the Dublin press. 
A dry summer had been followed by a wet autumn, and, about 
nightfall on December 27th, a heavy downpour of rain set in, accom- 
panied by a south-easterly gale. Somewhere between two and three 
o'clock the following morning, the edge of the Knocknageeha bog, 
which overlooks the Ownacree valley, gave way, and liberated a 
vast flood of peat and water. There was no immediate warning of
