They make a hole, and fill it with the ashes of babúl-wood, half a sér for every 100 tólahs of bugrawátí. These ashes they then make up in form of a dish, and mix them up with the bugráwatí, adding one tólah of copper, and twenty-five tólahs of lead. They now fill the dish with coals, and cover it with bricks. When the whole has melted, they remove the coals and the bricks, and make a fire of babúl-wood, till the lead and copper unite with the ashes, leaving the gold and silver together. These ashes are also called k'karal, and the lead and copper can be recovered from them by a process, which will be hereafter explained.
