In the process which we have used for testing wrapper tobacco with regard to these elements of the burn, the area of the leaf consumed, rather than the time elapsing before the glow is extinguished, is measured. The form of the apparatus used in this method will be understood by reference to the accompanying illustration (tig. 2). The essential feature is the form on which the leaf is wrapped, consisting of a col- lapsible wooden tube, one end of which tits into a glass tube of the same diamete...r. This latter is in turn connected with a second glass tube through which is drawn a current of air. The best material for making the wooden form is well-seasoned cherry with a straight grain, but ash has also been found to answer the purpose very well. From the wood selected is made a cylinder 5 inches in length, f inch in diameter .at one end, and tapering slightly to the other end (see tig. 3). In the larger end of the cylinder a f-inch hole is bored to a depth of 3f inches, and the shell thus formed is separated into six equal segments by saw- ing to a depth of 3i inches.
