To judge by a letter from the Russian Merchant Company, which was formed in London, it was at his own instance that Stephen Burrough in 1557 sailed from Colmogro, not to Obi, but to the coast of Russian Lapland to search for the lost vessels.[120] The following year the English were so occupied with their new commercial treaties with Russia and with the fitting out of Frobisher's three expeditions to the north-west, that it was long before a new attempt was made in the direction of the north-east, namely till ARTHUR PETS' voyage in 1580.[121] He was the first who penetrated from Western Europe into the Kara Sea, and thus brought the solution of the problem of the North-East Passage to the Pacific a good way forward. The principal incidents of this voyage too must therefore be briefly stated here. PET and JACKMAN, the former in the _George_, the latter in the _William_, sailed from Harwich on the 9th June/30th May, 1580. On the 2nd July/22nd June they doubled the North Cape, and on the 12th/2nd July, Pet was separated from Jackman after appointing to meet with him at "Verove Ostrove or Waygats." On the 15/5th land was in sight, the latitude having the preceding day been ascertained to be 71 deg. 38'. Pet was thus at Gooseland, on the west coast of Novaya Zemlya. He now sailed E.S.E., and fell in with ice on the 16/6th July. On the 20/10th July, land was seen, and the vessel anchored at an island, probably one of the many small islands in the Kara Port, where wood and water were taken on board.
