Lignitic dial was discovered on or near the coast of Coos Bay as early as 1855, and this is still the only productive coalfield within the state, although there are outcroppings of the mineral all along the Coast Range N.
Forests.-The White Mountain region and Coos county to the north of it, embracing in all nearly one-third of the total area of the state, is essentially a forest country.
Of this total the only other large items were clay and clay products (valued at $371,640), and mineral waters ($259,520; of which $150,512 was the value of table waters) from nine springs, four in Rockingham, three in Hillsboro county and one each in Coos and Carrol counties-and other mineral waters were used in the manufacture of soft drinks.

On the coast, Coos Bay, a tidal estuary, is the principal harbour between the mouth of the Columbia and San Francisco; it admits vessels drawing 14 to 16 ft.
Of water, and both the north and south forks of the Coos river are navigable for vessels of light draft (the depth at low water is only 1.5 ft.) 14 m.
The principal railways are: that of the Oregon Railroad & Navigation Company (controlled by the Union Pacific), which crosses the north-eastern corner of the state and then runs along the bank of the Columbia river to Portland; three lines of the Southern Pacific in the Willamette Valley, the main line connecting Portland with San Francisco; the Astoria & Columbia River, connecting Portland and Astoria; the Coos Bay, Roseburg & Eastern Railroad & Navigation Company (owned by the Southern Pacific), connecting Coos Bay with one of the Southern Pacific lines; and the Corvallis & Eastern (owned by the Southern Pacific), connecting Yaquina Bay with all three lines of the Southern Pacific. Throughout the Cascade Mountain Region and the great semi-arid region east of those mountains, which together embrace more than two-thirds of the state's area, there is not a railway.
There are four customs districts: southern Oregon, with Coos Bay as the port of entry; Willamette, with Portland as the port of entry; Oregon, with Astoria as the port of_entry; and Yaquina, at the mouth of the Yaquina river.
