Rensselaer Semi-Weekly Republican, Volume 19, Number 26, Rensselaer, Jasper County, 3 December 1897 — Holes in Sails. [ARTICLE]

Holes in Sails.

A sea captain has found that the sails of a ship when filled with a number of small holes bear it along more rapidly than when they are perfectly whole. He says that an ordinary sail cannot receive the full force of the wind, owing to the bulk of stationary air that fills up the hollow of the concave canvas.
