They wouldhave to be self-adjusting, so far as quick adaptationto changing weather conditions and sudden runningstrains is necessary. But such cannot be auto-matically obtained yet. The best fasteners areapproximate in their action. The worst are clumsymechanical contrivances. Most, good or bad, linkthe heel-band with the ski blade. Some fastenersare placed on one or both cheeks. We have already made it plain : the heel-band,when stretched out round the foot, should be freeto revolve in the same plane as the flat of the ski,as set forth in the following sketches :—. FAULTY LEVERAGE. 288 SKI-RUNS IN THE HIGH ALPS Here lateral impulses or checks are transmittedthrough the point of attachment of the heel-band. COBREOT LEVEBAGE.
