Red Cross Knitters and Sewers, Please Learn How to Use a Cane

IF you enjoy sewing out-of-doors, but object to a lap-full of the necessary materials, here is a little device which will make sewing in the garden an unalloyed pleasure. And best of all, you may not have to buy a single article in order to have this attractive combination sewing- bag and table.

��A Soap Bubble Can Be Made to Last for Months

THE air of an ordinary room is filled with tiny particles of matter which fall on the airy soap bubble, alter the surface tension, and — poof — it is gone. The effect of these minute particles on the stability of bubbles was first brought to light by Sir James Dewar. He ex- perimented in clarified air until he was able to produce bubbles which lasted for months. He has even produced a soap film, which was a year old recently and which seems to remain just as it was made.

So tell the children that the secret of successful soap bubbling is to have a perfectly pure soap-solution and to blow the bubbles in and with air that is also perfectly pure.

��Individual Protective Housing for Delicate Plants

FOR the protection of transplanted hothouse plants, Mr. John C. Mueller of St. Louis has invented a device which may be described as an individual pro- tective housing with hothouse and irriga- tion features. The box-like device with a slanting top is placed over the plant which needs protection and is secured by pressing the lower edges of the structure into the ground. A removable top with strips of glass and ventilated by holes with raised edges, calculated to keep the rain-water from flooding the plant, is provided. If desired, a water tank may be placed in the upper part of the housing, from which water* may be slowly supplied continu- ously to the growing

���plant.
