Arctic Expedition.
be rom the West Briton.l VWeha,zbeen favoured with the Sight of a letter recently re- ceived by a naval ofice' in Cornwall, from ali officer toDilecde with the expe4ition whtih lately left this country for th e purpose of pro- ceedlnt by land to explore the shores of the Arctic Sea, from Re- punle Bay, of whicb the following extraet wil, we doubt net, be ac- cepttable to our wmders*- MIla Majesty's discovry sloop Griper, Stromness, July 2. Id24 I catrot leave the Orkney Itsles without writing you. Of the nature and objects of this expedlLon I suppose you are already well infonrned it is therefore unnecessary for tne to enter into details. Every thusg whicb could be thought of for the conmfort and safety of these engageEl in it, has been piovided by Government. Wire have complete fur dresses of raroon skin; bags about six feet long and sufflciently wide for a man to get into and sleep in, lined with the sama material; and pillows whibch are air tight, and mnay be iiflated when necesavry, to repose on. Theme pillo,vs are made of duck of'i the closest texture of which two piecei are glued togeLher by a coln position tnade of fndia.rubber diec.Ied in naphtha, which renders them air.tighb and the pillows are-then formed. Thetm is a stop-cock at one corner through which they are inflated, and when not used, the nir is nllowea to escape. When empty, a pillow can be folded up in a small compass, and c;rried in the pocket. We have also water-proof dresses swimming jacleets, and camp equipage suited to the climate we have to encounter, all prepared in tie same manner. We have also coverings of the same material for two boats which we have In frame; each of these boats, when completed for service, will weigh about 1501b.; thev are designed to carry six persons each, with some necessaries. 'tlhe party consists of 12 persons, and if we finul the sea clear of ice, we are to paddle along the shore. We take two ponies from Stromness, to convey the luggage across the peninsula fromn Repulse Boy to the Arctic Sea; theY are strong, ardy, and handsome little apimanls. We have mrteTiaas to form a cart tor the lunagc on our arrival, and six pasir of wheels, of dif. felent aizes an widths. It is, however, generally thought that Esquimuux dogs will be mos servjceable in conveying our luggage on sledges, than the ponies in a cart; and we have a number of sledges of Yarious sizes,- in case it should be found necessary to use them. The Snap, surveying sloop, accornpanies us as far as the ice near Hadson's Strait, where we take out the wtores, provitsins, &ec., and part comnpany. Tue Snap will then _roceed to Newfound- land, to continue thte suveys of that coast. These particulars will give you some idea of the mntner in which we are to proceed on our arrival at Hndson's Strait. I trust we shall fully succeed in the objet in view; at all events, every thing that courage and perse- veranee can accmlihwilbeel'tte. AThCTIC RXfPEDdtToy.
