--Seven kegs of powder, of one hundred pounds each, were found in the culvert under the Dry Dock
, at Norfolk
, Wednesday, and it is supposed still more will yet be found.
They were placed there on the night previous to the firing of that establishment, no doubt with the intention of blowing the Dock to pieces.
Two or three kegs were taken out the following morning, which were then supposed to be all that were placed there.
