"In the summer of 1850, there went up a whaling fleet of one hundred and fiftyfour American vessels, manned as above and of a like average value. This fleet, in the course of a few weeks, left for their pursuits in those inhospitable regions, took 243,680 barrels whale oil, and 3,654,000 pounds of bone.

"In the current year (1851) there went up a fleet of about one hundred and fortyfive American vessels; but their returns have not been received; partial accounts of wreck and disaster only have reached us. They are startling.

"The lives and property at stake there, for the two years for which we have complete returns, may thus be stated:

"The losses during the year 1851 have been unprecedented, so far as heard from. No less than seven sail of this fine fleet of 1851-the Honqua, the New Bedford, the Arabella, the America, the Armata, the Mary Mitchell, and the Henry Thompsonhave been wrecked there and left behind as monuments of the dangers which meet these hardy mariners in their adventurous calling. There are reports of other losses and wrecks: these are certain; and though several of them were lost, not on shoals, but otherwise, yet these are enough to tell of imperfect hydrography, and to show the national importance of looking to it; for it may be so that, in case of loss in the ice, the knowledge of a sheltered anchorage near, and which a survey would give, would have prevented the exposure to the ice which induced the loss.

"All our Commerce with what is called 'the East' is not so valuable as this was for 1849 and 1850."

NEW LIGHT AT THE ENTRANCE OF CHRISTIANIA FIORD.

ROYAL NORWEGIAN MARINE DEPARTMENT, CHRISTIANIA, June 5. As the present coal-light on Færder, at the entrance of the Christiania Fiord, will, in the course of the summer, be replaced by a fast lens-light of the first class, notice is hereby given that in the course of twelve or fourteen days the said light will be placed 130 ells (260 feet) south of the present light-house, about 190 above the level of the sea. The light on this place will be equally visible, as from its present site, to those vessels coming from sea, and seeking the Christiania Fiord; only in cases of vessels within Færder, coming west of the Fuglehuk Light, will the light on Færder be invisible, in consequence of the high ground north of the light.

Due notice will be given of the period when the new apparatus will be lighted.
