River, and these were answered both from the range behind Cardwell, and from Hinchinbrook, so it was evident there were blacks on the island, though most likely concealed in some of the hidden valleys, which, from the volcanic nature of the country, were so plentiful, and so difficult to find. Lizzie was now brought forward, and subjected to a most rigid cross-examination, with which I will not trouble the reader. She said that they must have crossed over to the main-land, for every place had now been searched. We were in despair, when Abiram Hills said -- "Baal bora ground been sit down along of Hinchinbrook, Lizzie?" A "bora ground" is a particular place to which the blacks are in the habit of resorting at certain seasons of the year, to hold "corroborries" or dances, and also to perform divers mysterious rites on the young people of both sexes attaining the marriageable age. What these solemnities really are, is but little known, and they seem to differ widely in each tribe. In some, the young girls have a couple of front teeth knocked out; in others they lose a joint of the little finger; and at that time the hideous lumps with which the men embellish their bodies must be raised.

Mine know one fellow bora ground, plenty black fellow sit down there, mine believe. My word, plenty d--d fooly me!" We could see from the girl's face that we were now on the right scent, and having ascertained that she could take us to the "bora ground" by the following evening, we finished our pipes, and lay down to sleep, thankful for what promised a possible solution of the mystery. The Cleveland Bay party consisted of seven white men and two black boys, so we now mustered a strong force. Lizzie would hardly allow us time to swallow our breakfast, so impatient was she to be under weigh; and one wretched man, lingering for a moment later than the rest of us, over a slice of beef and damper, found himself the object of general attention, when our little guide stamped her foot, and, trembling with indignation, said --
