CHAPTER XII.
Return to the Zambesi--Bishop Mackenzie's grave--Frightful scenes with crocodiles--Death of Mr.Thornton--African poisons--Recall of the Expedition.
We put to sea on the 18th of October, and, again touching at Johanna, obtained a crew of Johanna men and some oxen, and sailed for the Zambesi; but our fuel failing before we reached it, and the wind being contrary, we ran into Quillimane for wood.
Quillimane must have been built solely for the sake of carrying on the slave-trade, for no man in his senses would ever have dreamed of placing a village on such a low, muddy, fever-haunted, and mosquito-swarming site, had it not been for the facilities it afforded for slaving.

The bar may at springs and floods be easily crossed by sailing-vessels, but, being far from the land, it is always dangerous for boats.

Slaves, under the name of "free emigrants," have gone by thousands from Quillimane, during the last six years, to the ports a little to the south, particularly to Massangano.

Some excellent brick-houses still stand in the place, and the owners are generous and hospitable: among them our good friend, Colonel Nunez.

His disinterested kindness to us and to all our countrymen can never be forgotten.
