steam shovel

At Lahontan the teams were engaged on the earthwork of the dike with the adjoining Lahontan Beach canal south of the dam. Paving of the up-stream slope of the dam was carried out by night shift in steam shoveling rock at the quarry and delivering by cars and cableway to the dam, where paving was placed by day shift and nearly completed to the present top of the dam at the end of the month.

I have never had any experience with steam shoveling.

A noun use.]
