For a first-class shoveler there is a given shovel load at which he will do his biggest day's work. What is this shovel load? ... it was found that a first-class man would do his biggest day's work with a shovel load of about 21 pounds. ... [p. 66] At the works of the Bethlehem Steel Company, for example, as a result of this law, instead of allowing each shoveler to select and own his own shovel, it became necessary to provide some 8 to 10 different kinds of shovels, etc., each one appropriate to handling a given type of material ... a small shovel for ore, say, or a large one for ashes.
