86sufficiently compact and lightweight so as to allow it to be easily trans-ported, e.g., on the back of an animal such as a donkey-- see Molenaar(1956). A crew of this basic construction, with necessary bearings andhandle for manual crank-operation,would cost about $20-$35, depending onavailable materials (Molenaar, 1956). Typical performances of such devicesare listed in Table 3.7, part A.A variation of this basic wooden design utilizes instead a metalauger which turns inside an outer metal cylinder, as in Figure 2.3.
