Rost

In the mountaynes also, at certaine seasons, there flocketh innumerable the Bogong Moth. The people gather them in cavernes, and rost them in fire, whereby they become rich meate, full of oyle, and with a taste like unto nuts. So plenteous is this harvest, that many tribes do assemble together for mirth, for trafficke, and for solemn rites, even as we resort unto fayres and markets. These victuals, which to a stranger may seeme strange and loathsome, are to the dwellers of that land both sustenance and treasure. They shewe howe Nature, though harsh and barren, yet provideth for her children, if only they have knowledge to seeke her hidden store. In such wise do the ancient inhabitants teach their youth, that the desert is not void, but rather a banquet spread by the earth herselfe.
