Titles read: "Dryland swimming".
Pathe Studio, London.
In a set of a living room we see a woman in a swimsuit lying on a contraption that supports the body while you learn to swim - or perfect your swimming strokes. The frame was designed by WJ Howcroft, "the well-known swimming authority".
The woman demonstrates breast stroke, the front crawl (with correct breathing) and back crawl. It all looks quite funny!
