ALBATEOSS EXPLOEATIONS ; ALASKA, WASHINGTON, AND OREGON. 87 
A subsequent run from the Sannakhs to Bird Island on August 4, developed a 
current of 1 knot per hour S. W., so it will be seen that the currents are not uni- 
form, and it is more than probable that they are affected by the tides. 
While engaged in sounding oft' the east and south shores of the Shumagins, from 
Atkin Island to Chernabour, a current of seven-tenths mile per hour was found setting 
S. 53° E. ; and from Castle Rock N. 84° B. 65 miles, thence to Mitrofania Island we found 
it was setting N. 18° W., about one-half mile per hour. 
From Mitrofania Island to Light house Rocks, and thence to Trinity Islands, the 
current was about Isi. 78° B., three-fourths mile per hour. 
We were within the influence of the tidal streams much of the time while off' the 
east coast of Kadiak, which affected us more or less according to our distance from 
land, and made it difficult to determine the amount of drift. The resultant of tides 
and currents indicated a set of about one-fourth mile per hour to the northward and 
eastward. 
On Portlock Bank north and east from Kadiak we found a current of four-tenths 
mile per hour S. 24° W. to longitude 151° 00' 00" W., S. 65° W. three- tenths mile per 
hour to 148° 30' 00" W., and S, 10° E. four-tenths mile per hour to 147° 30' 00" W., 
increasing in force and taking a more easterly direction as we approached Middleton 
Island. 
From the island to the reported position of Pamplona Rocks, and thence to lati- 
tude 55° 30' 00" north, the current was to the northward and westward, averaging 
six-tenths mile per hour, and S. 60° W. one-half mile per hour to the south end of 
the Queen Charlotte Islands when we again came within the influence of the tides. 
From September 19 to October 21, between Cape Flattery and San Francisco, 
the current was to the southward and eastward, averaging about three- tenths mile 
per hour, except during one day off Gray’s Harbor and Shoalwater Bay, where it 
set north four-tenths mile per hour. 
29. PARTIAL LIST OF HARBORS AND ANCHORAGES BETWEEN KADIAK ISLAND 
AND UNALASHKA ISLAND. 
The following li^t of harbors and anchorages is inserted in this report chiefly for 
the purpose of calling the attention of strangers to localities where vessels have found 
shelter. The information respecting them was obtained principally from local authori- 
ties, very few having been visited by the Albatross. In dealing with this information 
it should be borne in mind that the vessels navigating the regions in question are for 
the most part light, handy schooners, and the availability of a harbor is very apt to 
be considered with reference to the craft iu which the informant has been in the habit 
of sailing. Some of the harbors are designated as good for all classes of vessels, and 
here again a word of caution may be necessary, as the largest vessel ever seen among 
the islands was probably a sloop-of-war. 
The positions given are approximate, and are only intended as a guide to enable 
the navigator to recognize localities in case of conlrision or absence of names on his 
chart. The list is arranged with reference to longitude, from east to west. Too much 
dependence should not be placed on any of the charts of this region, as very few accu- 
rate surveys have been made, and most of the data are from the reconnaissances of 
early Russian navigators. The eye and the lead will continue to be the most reliable 
guides until the region has been properly surveyed.
