A white cloth is usually tied to croquet arches when the game is played late in the evening. A much better plan is to slip a piece of white rubber tubing about 1 ft. long on the arch. This tubing can be purchased at any local drug store. This makes the top part of the arch conspicuous so that it may be plainly seen in the dark, and, when the tubing becomes soiled it can be cleaned off with a damp cloth. - Contributed by John Blake, Franklyn, Mass.
