Ether 10:20–23

And they built a great city by the narrow neck of land, by the place where the sea divides the land. And they did preserve the land southward for a wilderness, to get game. And the whole face of the land northward was covered with inhabitants. And they were exceedingly industrious, and they did buy and sell and traffic one with another, that they might get gain. And they did work in all manner of ore, and they did make gold, and silver, and iron, and brass, and all manner of metals; and they did dig it out of the earth; wherefore they did cast up mighty heaps of earth to get ore, of gold, and of silver, and of iron, and of copper. And they did work all manner of fine work.
