succeeded in getting one of these carronades ashore above high-water mark. From this circumstance that beach is still called "Cannon Beach". In his Report, dated February I, 1847, House Miscellaneous Report No. 29, 30th Congress, 1st Session, ordered to be printed February 28, 1848, Lieut. Howi- son mentions Tillamook Head as "Killimuk's Head".
A. N. Armstrong, for several years a government surveyor in Oregon, published a book entitled "Oregon", in 1857. In this book, page 74, he calls the bay, Tillamook. On page 101 he calls the Indians "Tillamooks (or Killamooks)". These are the earliest mentions I have found in early books on Oregon of the name Tillamook.
I have been unable to ascertain when the name was changed to begin with a "T" instead of a "K". Judging from the date of books, mentioning the name, it was about or at the time the County was created.

Coos County.
Coos County was created December 22, 1853, by the Ter- ritorial Legislature. (Special Laws of 1853-4, page 13). It comprised parts of the western portions of Umpqua and Jack- son Counties, and south of the Umpqua River. Its western boundary was the Pacific Ocean.
Its name is derived from a tribe of Indians of the Kusan family, whose principal habitat was at what is now called Coos Bay, in that County. The name of the tribe and of the Bay was the same. In Lewis and Clark's "Journals" the name is spelled Cook-koo-oose, ("Original Journals," Vol. 6, page 117). This name they obtained from the Clatsop Indians.
In Slacum's Report (1837) he gives the name of Coos River as Cowis. In Wilkes' "Western America," page 73, he spells
