THE ARCTIC EXPEDITION.
The greatest activity prevailed at Greenhithe at the
earliest dawn 'of light yesterday morning on board the
ships and steamers of Captain Sir Ed ward Belchet's ex-
pedition for the Arctic regions, the Lightning steam-
vessel, and the steam tugs ordered to tow the sailing
vessels Assistance, Resolute, and North Scar down the
river to the Noro, where the tugs will be relieved by the
Basilisk steam-vessel, 400-horse power, Commander
Gardiner, and the Desperate seam-sloop, 400-horse
power, Lieutenant Stevens. The vessels of the Arctic
quadron stared from Greenhithe at a quarter before
five o'clock, A N., and at about twelve o'clock noon were
brought up at anchor about twenty miles below Graves-
eed, toe the Purpose of .communicating with the com-
manding officers of the Basilisk and Dsperate steamers,
and relieving the sreana:tiigs of their previous duty.
A titimb,r of persons went down to Greenhithe in the
course of the day to bid adieu for a time to the officers and
crews of the expedition, but of course they were disap-
pointed. It may be in some degree consolatory how-
ever for them, and all the r, lations and friends of the
officers and crews of the expedition, to know that letters
will reach them bef, re they leave the Orkney Islands,
it posted before the mail leaves London this afternoon.
It may be also important to state that in the event of the
letters not being posted to-day, slight hopes can be en-
tertained that they will reach Stromness in time to be
delivered to the officers and crews of the expedition, as
the mail from Aberdeen only leaves once a week for
Stromness. It should also be particularly remembered
that all letters and papers should be addressed to the
" Arctic Expedition, Stromness."
'I he Monkey, steam-vessel, left Woolwich yesterday
evening with duplicate sets of sails for the screw-
steamers of the Arctic expedition, to render them doubly
supplied in that necessary description of stores, as these
vessels will be moat actively employed, even when their
coals are all consumed. The decks of the whole of the
vessels were piled up with firewood yesterday—a very
large supply of that article having been taken on board.
Among the stores received during the last few days has
been a large quantity of strong Burton ale, in casks.
This agreeable beverage has been found from experi-
ence the most invigorating and refreshing drink for the
sailors, when exposed to extraordinary exertion in the
northern latitudes. The ale his been procured, by di-
rection of the Lords of the Admiaalty, from the brewery
of Messrs. Samuel Allsopp and Sons, of Burton-on-Trent.
E. M. and J. Rettie have supplied stoves to the Resolute,
which occupy but little room, and consume few coals in
comparison to the formerly fitted cumbersome stoves.
Arnot's stoves have been supplied to the Pioneer.
Captain White has presented jars of his curry and
bottles of his anti-scorbutic remedy for scurvy, and Mr.
Arrowsmith several of his new maps, with Penny's
and Dr. Rae's recent discoveries.
