Harley finds little “data available on scientific shoveling,” save for F. W. Taylor’s The Principles of Scientific Management (1911) — discussion of shoveling at pages 64-69 — and Daniel J. Hauer his “A Hundred Hints for Shovelers,” in The Contractor vol 25 (March 19, 1918): 135-139
Thought to make this an animated gif, but the figure is not at consistent scale throughout this series of halftones. Have been thinking about early cinema — Hollywood, silent films, in part because of Well ain’t she a fine looking Dame? — and this sequence fit right in. The Hauer article (“Hundred Hints” — actually 101) is poetic in an aphoristic way. Shoveling — like scraping — is a favorite activity.
To be continued.
