This done, he [an elephant] took up the pingo and moved away from the spot; but at the distance of about a fathom or two, laid it down again, and ripping open one of the bundles, took out of it all the contents, somans [footnote: Woman's robe], cambāyas [footnote: The figured cloth worn by men], handkerchiefs, and several pieces of white cambrick cloth, all which he tore to small pieces, and flung them wildly here and there. He did the same with all the other pingoes.
A measure of weight equivalent to that which can be carried using a pingo, perhaps about 55 pounds (25 kilograms) (see the 2013 quotation).
