In half an hour they had explored and pronounced safe as large a bathing place as their supply of rope would “fence in” and then began the “fencing” process. They cut several stout stakes six feet long and took them to the water’s edge. Then the three girls in bathing suits assumed their new duty as water pile-drivers. They took one of the stakes at a time to a point along the proposed boundary line of the bathing place, also a heavy mallet that had been brought along for this purpose. A wooden mallet, by the way, was much more serviceable than a hatchet for such work, inasmuch as, if dropped, it would not sink, and moreover, it could be wielded with much less danger of injury to any of those working together in the water.
