A FIELD TEST OF CANAIGRE-TANNED HEAVY LEATHER IN LOW QUARTER SHOES

摘要

Dependence on foreign vegetable extracts was a matter of grave concern during World War II. The U.S. Department of Agricul¬ture, after a survey of indigenous wild plants which could be used in their place, settled on canaigre, a tuber of the Southwest, for a major effort that included cultivation and manufacture of a commercially-acceptable extract. Under an agreement with the U.S, Amy Quartermaster Research and Engineering Command, the extract was used in the tanning of sole leather on a pilot plant scale and a portion of the leather obtained in this test was used as components of low-quarter shoes for troops on garrison duty. The service characteristics of these shoes were studied over a period of 14 months.
