There is a hint of the large Aveling horse on the smoke box of this 10 HP engine. The "under tank" for additional water is just visible above the rear of the left front wheel and is similar to one fitted on the UK's oldest Aveling road locomotive, number 4561 of 1900. The crew and engine have taken a momentary pause for the photographer in their timber hauling work at the Lumpkin Mill, Butte County, Calif. This is the second Aveling, number 2259 of 1887.
