TERRIBLE CATASTROPHE – FORTY-NINE CHILDREN DROWNED. – From the Quincy (Ill.) Herald we learn that a most terrible calamity, rivaling that of the Pemberton Mills, occurred on Thursday last, near the town of Hardin, Illinois, on the Illinois river, and about twenty-five miles above Alton. Fifty school children in attendance at a university in that place, went out upon the ice to play. The ice gave way, and with one exception, all were lost. Our informant was unable to give further particulars, but he represents that the village was the scene of universal mourning, almost every family in it having lost one or more of its members.
