E P Burton Lumber Company was formed in 1901 to exploit timber reserves in North Charleston, SC, as one of the first industries in the area. (Very soon thereafter, the US Navy began work on the Charleston Navy Yard.)
The 6 was delivered as a wood-burning logging Prairie produced to a pattern used by many lumber companies in the Southeast. Fuel capacity originally listed as 3 cords, but even then the company foresaw converting the engine to coal burning.
Locobase likes to include specification notes that add to the image one might have of the working life of a locomotive. Here the note refers to water management: "Apply syphon under cab board on left side with 25 ft of suction hose. Syphon to be arranged also as an ejector ...[to] discharge water from tank, always leaving a supply of 8" in the tank, with 25 ft of delivery hose, this for the purpose of supplying water to a skidder tank."
The ejector gained its power from a steam line, but only to propel the water into a tank as indicated in the quote.
It rolled on 40 lb/yard (20 kg/metre) rail over a 20-mile (32 km) line.
After its time with EP Burton, the 6 would serve three more logging companies: German Land and Lumber, Limestone, and Dowling & Camp.
