"A recent discovery in the sluice boxes of the Logan Mine in Illinois Valley of a Spanish coin bearing the date mark of 1784, is held to establish the approximate date of gold-seeking operations of the Spaniards in southwestern Oregon.

Findings made in the deep gravel throughout the past generation have confirmed the belief in the minds of those who have been in touch with them that during the mission or pastoral period in California and antedating any local history, Spaniards visited this section of Oregon in quest of gold."
