High water.
--The river rose several feet yesterday, and last evening there was every probability that it would continue to rise throughout the night. The heavy rains, together with the melting snow, have produced a freshet more formidable than any that has occurred here for years. All the islands in this neighborhood are overflowed, some of them entirely, leaving only the tree-tops to mark their locality. On Mayo's Island a large force was at work, yesterday, endeavoring to secure the timber, which was in danger from the surrounding flood. The water at Rocketts was nearly up to Main street, and business operations at the lower wharves were suspended. All the mills on the Manchester side stopped running. At the falls, the rushing and surging of the waters presented a view of much grandeur, and below Mayo's bridge the broad expanse of the river, bearing on its surface a vast quantity of drift lumber and logs, was spectacle altogether unusual for this vicinity.
