Bast, or bass, is the inner bark of various species of the linden. It is used in Europe (chiefly in Russia) largely for manufacturing mats, which form a most excellent protective covering for plants, etc., securing them against frost and cold. It is also used quite extensively in horticulture for tying up plants and for binding grafts, etc. Its soft ribbon-like character renders it peculiarly valuable for this purpose, - far superior to twine, osiers, etc.
A very excellent article of bast may be obtained from the basswood of this country. The outer bark having been stripped off and soaked in water, the inner bark separates in long ribbons, which are then dried and stored away for use.
