He then works the skins alternately by moving his feet up and down, being assisted in this treadmill kind of labor by the elasticity of two bamboos, of eight or ten feet in length, the butts of which, being firmly fixed in the ground, enable him to retain his balance by grasping one with either hand.

From the yielding top of each bamboo, a string descends attached to either big toe; thus the downward pressure of each foot upon the bellows strains upon the bamboo top as a fish bears upon a fishing-rod, and the spring of the bamboo assists him in lifting up his leg.

Without this assistance, it would be impossible to continue the exertion for the time required.
While the "bellows-blower" is thus getting up a blaze, another man attends upon the well, which he continues to feed alternately with fresh ore and a corresponding amount of charcoal, every now and then throwing in a handful of fine sand as a flux.
The return for a whole day's puffing and blowing will be about twenty pounds weight of badly-smelted iron.

This is subsequently remelted, and is eventually worked up into hatchets, hoes, betel-crackers, etc., etc.

being of a superior quality to the best Swedish iron.
If the native blacksmith were to value his time at only sixpence per diem from the day on which he first started for the mountains till the day that he returned from his iron-smelting expedition, he would find that his iron would have cost him rather a high price per hundredweight; and if he were to make the same calculation of the value of time, he would discover that by the time he had completed one axe he could have purchased ready made, for one-third the money, an English tool of superior manufacture.
