From 7 p.ra,, July 2, to 4 a.m., July 3, steaming from I\fe.rcus Bay to- 

 wards Saint Michael's, Norton Sound, the current set the vessel east- 

 northeast 30 miles. 



On the afternoon of July 12 a short trip was made at Cape Prince of 

 Wales. A strong northerly current necessitated frequent working of the 

 engine to hold the vessel in position. Wind moderate and variable, 



July 30, while made fast to the shore ice at tho oast end of Herald 

 Island, the current was measured with the chip and line and found to be 

 to the northward 1 knot per hour. There was no appreciable change in the 

 velocity or direction of the current during the time the C0R?/IN remained 

 at the island — from 9:45 p.m., until 3 a.m. The ice was setting steadily 

 northward during that time. 



At Cape Wankerem, latitude 58° 05', longitude 176° 30', a tidal 

 current was observed, with a rise and fall at that time of about 2 foot, 

 the flood setting along the coast to the northv/ard. 



At 7:30,, August 3, in tho Arctic Ocean, south of Vifrangol Island, 

 being able to sco a mile or more, wo got under way and steamed to the 

 northwest under one bell until 9, when it again shut down thick, just as 

 we ccono up. to the ice, Tho engine was stopped and soundings imdo in 19:|- 

 fathoms of T/ator, soft bottom, tcmporaturo at bottom 40°, the current 

 setting to tho V70stv/ard very gontly, not more than a quarter of a knot. 



The bed of tho nn.vigablo part of the Arctic Ocean lying north of 

 Boring Straits is a vast plain, with an average depth of less than 30 

 fathoms. South of Wrangel Island the soundings are remarkably regular, 

 at 22 fathoms for many miles, but toward the Asiatic side of the strait 

 the ¥/ater deepens to 27 fathoms at a distance of 20 miles from the coast, 

 gradually shoaling to 14 in the next 10 miles. Just east of Herald 

 Island the depth exceeds 30 fathoms, and to the northeast a few miles 

 reaches 40, This is undoubtedly caused by tho curi^nt which sots north- 

 ward between Herald Island and the Herald Shoal, 



On the 4th of August, while cruising in the strait south of Wrangel 

 Island, our obsyrvations showed a west-northwest set of 12 miles, tho 

 wind light ^and variable. 



On the 4th and 5th of August tho ship's position was dotorminod by 

 observation, showing a. current of 1 knot per hour north-northwost; wind 

 moderate, from cast to southeast. 



On the lOth of August J while at anchor off the south coast of 

 Wrangel Island, near the edge of the ice-pack, the cixrront was ob- 

 served to be setting in a northeasterly direction, from one-quarter 

 to ono-half a loiot por hour.
