“That here in the Olympic region you see what is literally an unknown, unexplored scope of country, as foreign to the foot of mankind as it was countless ages gone by. So far as history reads, neither white man nor red has ever ventured fairly within these limits; a mountainous waste which rises from the level country, within ten or fifteen miles of the Straits of San Juan de Fuca, in the north, the Pacific Ocean in the west, Hood's Canal in the east, and the barren sand-hills lying to the far south.
