(Lake Creek) was being vigorously prospected, with the hope of a 

 substantial production very soon. 



Some platinum is recovered with gold in the beach placers to 

 the north and south of Marshfield, but the yield has not yet had 

 any appreciable effect on the industry. 



Nickel deposits occur near Riddles, Douglas County, but no 

 production is reported at the present time. 



One quicksilver mine is located near Cottage Grove, Lane 

 County, which, however, has not had a very prosperous history. 



Common brick and drain tile are made at many localities in 

 Oregon, but clays suitable for pottery of the better grades have 

 either not been located, or if known, have not been worked. 



All attempts to find oil in commercial quantities in Oregon have 

 so far failed . At the present time drilhng is being done near Waldport 

 on the coast, and near Roseburg and Vale on the eastern boundary 

 of the state. So far no success has been met in these undertakings. 

 Near McMinnville, Yamhill County, there are several salt springs 

 and gas wells, one of which in Polk County illuminates a ranch 

 house and is used for cooking. This well has given off natural 

 gas for over thirty years. No scientific development of this field 

 has yet been undertaken. It seems to be the most promising 

 place in Oregon for natural gas, and possibly petroleum. Some 

 "shows" of oil have just recently been reported from a Harney 

 County (southeastern Oregon) well, now down to 1,241 feet.. 



A fair grade of sub-bituminous coal of Tertiary age is mined in 

 the small basins of marine Tertiaries near the coast. The pro- 

 duction is small and comes from two or three small mines. The 

 daily output probably has never exceeded fifty tons. 



A great deal of crushed stone, mainly basalt and diabase, is 

 utilized annually on our highways. Limestone is found in both 

 the northeast and southwest portions of the state. The product 

 is distributed largely by the State Lime Board. 



The most valuable and unique decorative stone, a handsome 

 black marble, anywhere in the state and perhaps anywhere in the 

 Pacific Northwest is quarried near Enterprise, Wallowa County. 



The state of Oregon cannot be said to be a mining state, though 

 it has a promising future in this direction. The state is very
