Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 23, p. 235. Works numbers 18718 in March 1901.
Logging in Mason and Grays Harbor counties on Washington's Olympic Peninsula imposed some severe demands on locomotives and these are reflected in the specifications. Curves of up to 20-deg radius, grades of 7% (yes, 370 feet to the mile). That latter incline was to be scaled by this locomotive pulling one loaded car of 30 tons on the log track at 20 mph. Or it could push logs between the rails, for which the specs required Baldwin to "provide means for wetting slide log way, between tracks." The tender was sized to allow 2,100 gallons for the boiler - enough for a 12-mile round trip.
Locobase hasn't been able to establish the meaning of the locomotive's name, which accompanied it when it joined the Phoenix Logging family in 1907.
