Balls of Fire.?The ship Portsmouth, just arrived at Warren from a whaling cruise, reports, that on the 18th of March, lat. 57 S., lon. 74 W., she experienced a severe gale. While scudding before it, a dense cloud gathered in the west, out of which issued a hurricane and many balls of fire. One of these struck the cutting pendants at the main-mast head, and fell in fragments on the deck, setting fire to the mast-head and rigging, and doing other damage. We do not remember to have heard of such an occurence at sea..?The Portsmouth has $20,000 in California gold dust..?[Brooklyn Eagle, of the 11th nit.
