of them twelve feet in thickness. The rock is easy to excavate
near the surface, but will probably be found harder as it goes
down. Free gold is found at the top.
It has been known for twenty-five years that gold existed in this district, and the Treasure mine was worked by arastra for a little time, but abandoned as unprofitable. More recently it has been reopened by other parties, who find it to assay from thirty dollars to forty dollars per ton, and to be free milling. There are several locations on the Blue Fiver ridge dating back no further than 1887. The Eureka, just south of Treasure, is an extension of the same. It has been tested in a small mill, and yields from twenty dollars to thirty dollars per ton. A group of three locations, three-quarters of a mile west of Treasure, are incorporated together under the name of the Blue Fiver Mining Company > and owned in Eugene. The assays of the ore from the Croesus vary from three dollars and seventy-five cents to one hundred and nine dollars per ton, and of the Imperial from five dollars and fifty cents to twelve hundred dollars. This company has a small mill.
The Lane County Mining Company also own three claims in this vicinity, but have worked only one, the Durango, which assays from two dollars and twenty-five cents to eighty-seven dollars per ton. The King-Bee, a large ledge, was worked to a limited extent twenty-five years ago, and abandoned. It assays from three dollars and seventy-five cents to two hundred and eleven dollars per ton, principally gold. Kear the King-Bee is the Buck, owned in Eugene, which assays from four hundred dollars to nine hundred dollars. There are perhaps as many more claims on and immediately about Treasure Hill, which have yet to be heard from. But there seems little doubt that this is a veritable gold-mining district.
Discoveries were also made twenty-five years ago, as well as more recently, at the heads of the Santiam and Molalla Fivers, in the Wallamet Yalley. On the latter, in Clackamas County, is a very thick ledge of bluish-white quartz, carrying free gold and pyrites, which assays twenty-five dollars in gold and two hundred and thirty five dollars in silver to the ton. Specimens from this district are shown which assay seven hun-
