The humidor is an ideal gift for any person who smokes. The wood for making one, as shown in the illustra- tion, may be of Spanish cedar, mahogany, or quartered oak, as the builder desires. The box and cover are made and glued together in one piece, then the cover is sawed off to insure a perfect fit. A strong corner connection is shown at A. A piece of a strawberry box or peach basket makes a good key to glue in the grooves. Care must be taken to run the grain with the width and not with the length of the strip.
Ill: The Amount of Moisture within the Box i, Shown on the Dial in the Cover
Finish the outside of the box with two coats of the desired stain, then cover with a coat of wax, shellac, or varnish. The inside should be finished with one coat of white lead and two or three coats of white enamel, to make the wood impervious to moisture.
In the center of the cover top is set a piece of glass and to the under side of the latter a hygrometer is attached with a little glue. This instrument tells the relative humidity, or the amount of moisture, in the air within. The moisture may be regulated by adding a few drops of water, as needed, to a piece of ordinary blotting paper placed on the inside. - Contributed by James T. Gaffney, Chicago.
