Rock Drill (Jacob Epstein) with its straining to one purpose, is a vivid illustration of the greatest function of life.' In 1940, however, recalling the horrors of the 1914–18 war in the context of the Second World War, Epstein reinterpreted the sculpture much more negatively: Study for Rock Drill (c. 1913) is a × charcoal drawing by Epstein which is part of The Garman Ryan Collection at The New Art Gallery Walsall. Whilst the exact date of the sketch is unknown, because it is a preparatory study for Epstein's full sculpture "Rock Drill", it has been dated to 1913. Epstein dismantled the original sculpture:
Philip Hepworth by a hipped roof clad in pantiles." Another early design was that of an arts-and-crafts thatched house named 'Bolton Muir' (1930) in Gifford, East Lothian. In 1931, Hepworth was featured in a book by architectural critic Trystan Edwards. Published in Zug, Switzerland, this 91-page hardback book, part of a series on the leading architects of the day, was titled "Some recent work of Philip Hepworth". It was illustrated mostly with black-and-white photographs of the buildings designed by Hepworth.
