shaped brand. Mrs. Dolly Kiger applied the name of the ranch to the community about 1874, according to information given the writer by C. H. Smyth, postmaster at Diamond in 1925. Diamond Craters are about six miles northwest of Diamond post office. There are about 20 of them occupying an area of some five square miles, described in USGS Bulletin 217. In 1927 Mrs. Minerva J. Kiger, of Corvallis, wrote the compiler that she was the Dolly Kiger referred to above. She confirmed the history of the name Diamond as given herein.
DIAMOND Hill, Linn County. Diamond Hill is on the east edge of the Willamette Valley about six miles north of the south line of Linn County, and about ten miles north of Coburg, Lane County. The compiler is of the opinion that Diamond Hill was named for John Diamond, prominent Lane County pioneer, whose home was near Coburg. Diamond Peak and Diamond Lake in the Cascade Range were named for the same man. John Diamond was born in Londonderry, Ireland, in 1815, and emigrated to New York in 1833. He lived at times in the states of New York, Michigan, and Illinois, and emigrated to Oregon in 1847. He took up a claim where the town of Coburg now stands. He sold the property in 1858, and after three years of traveling, settled just east of Coburg. For additional biographical information, see Walling's History of Lane County, page 488. Along with other pioneers, he made explorations into the Cascade Range, which accounts for the application of his name to geographical features in that area. The compiler does not know the circumstances of the naming of Diamond Hill. It seems certain that Diamond did not live in the locality, which was about ten miles north of his homesteads. He may have had some business interests there, or possibly pastured stock there. John Diamond was a sturdy citizen and neighbors may have complimented him on that account. Diamond Hill post office was established on the Linn County list on September 16, 1858, with James H. Pierce first postmaster. This office was closed September 28, 1869. An office with the name Diamond was in service from April 23, 1887, to October 4, 1887, with David H. Pierce postmaster. It was doubtless in the same community.
DIAMOND LAKE, Douglas County. This is one of the important mountain lakes of Oregon, and lies in the southeast part of the county between Mt. Thielsen and Mt. Bailey. It has an elevation of 5182 feet. About 1927 George H. Kelly of Portland and Wm. P. Vandevert of Bend, both of whom were familiar with the history of the middle Cascade Range, informed the compiler that Diamond Lake was named for John Diamond. This was the same man for whom Diamond Peak was named. Diamond discovered the lake from the summit of Diamond Peak in 1852. The name has nothing to do with the shape of the lake. See under DIAMOND HILL.
DIAMOND Lake, Klamath County. Diamond Lake is a station on the Cascade line of the Southern Pacific just northeast of Beaver Marsh. It was named for the large lake about twenty miles westward. When the railroad was built, the station was named Lonroth for Elias Lonnrot. 1802-1884, Finnish philologist and discoverer of the Kalevala, the great epic of Finland. Shortly after the Cascade line was built, the railroad changed the name from Lonroth to Diamond Lake. This was about 1926.
DIAMOND LAKE, Union County. Diamond Lake is in township 5 south, range 43 east, and drains into Elk Creek, a tributary of Minam
