    The American Sumatra Tobacco Corporation, Hartford, Connecticut USA
    A simplified procedure for measuring the specific volumes (filling values) of tobaccos utilizing ordinary 100-ml graduate cylinders and cast lead weights was devised and tested against two reported methods. Based on replicated tests on 23 samples of...

    Physical characteristics of cured tobacco. II. Some factors affecting certain physical properties

    ARTHO A.J.; MARSHALL H.V.; WEYBREW J.A.
    The American Sumatra Tobacco Corporation, Hartford, Connecticut USA
    A coordinated sequence of simplified procedures was used to measure leaf weight, leaf body (wt/area), strip yield, specific volume, relative fragility, and hygroscopicity on a set of twenty-four flue-cured and six Burley samples. Replicated...
