of at least 600 miles, the slave-trade in this quarter would be rendered unprofitable,—­for it is only by the ivory being carried by the slaves, that the latter do not eat up all the profits of a trip.  An influence would be exerted over an enormous area of country, for the Mazitu about the north end of the Lake will not allow slave-traders to pass round that way through their country.  They would be most efficient allies to the English, and might themselves be benefited by more intercourse.  As things are now, the native traders in ivory and malachite have to submit to heavy exactions; and if we could give them the same prices which they at present get after carrying their merchandise 300 miles beyond this to the Coast, it might induce them to return without going further.  It is only by cutting off the supplies in the interior, that we can crush the slave-trade on the Coast.  The plan proposed would stop the slave-trade from the Zambesi on one side and Kilwa on the other; and would leave, beyond this tract, only the Portuguese port of Inhambane on the south, and a portion of the Sultan of Zanzibar’s dominion on the north, for our cruisers to look after.  The Lake people grow abundance of cotton for their own consumption, and can sell it for a penny a pound or even less.  Water-carriage exists by the Shire and Zambesi all the way to England, with the single exception of a portage of about thirty-five miles past the Murchison Cataracts, along which a road of less than forty miles could be made at a trifling expense; and it seems feasible that a legitimate and thriving trade might, in a short time, take the place of the present unlawful traffic.

Colonel Rigby, Captains Wilson, Oldfield, and Chapman, and all the most intelligent officers on the Coast, were unanimous in the belief, that one small vessel on the Lake would have decidedly more influence, and do more good in suppressing the slave-trade, than half a dozen men-of-war on the ocean.  By judicious operations, therefore, on a small scale inland, little expense would be incurred, and the English slave-trade policy on the East would have the same fair chance of success, as on the West Coast.

After a land-journey of forty days, we returned to the ship on the 6th of October, 1859, in a somewhat exhausted condition, arising more from a sort of poisoning, than from the usual fatigue of travel.  We had taken a little mulligatawney paste, for making soup, in case of want of time to cook other food.  Late one afternoon, at the end of an unusually long march, we reached Mikena, near the base of Mount Njongone to the north of Zomba, and the cook was directed to use a couple of spoonfuls of the paste; but, instead of doing so, he put in the whole potful.  The soup tasted rather hot, but we added boiled rice to it, and, being very hungry, partook freely of it; and, in consequence of the overdose, we were delayed several days in severe suffering, and some of the party did not recover till after our return to the ship.
