The 1899 House Journal appears to have a misprint for Geer's vote in Tillamook County, giving his total there as 636. This causes Geer's county totals to be off from the statewide total by 1 vote. The compilation Oregon Votes 1858-1972, available at the Oregon Historical Society in Portland, gives the Geer figure in Tillamook County as 635, which allows the totals to match.
