It was evident that these divisions in the company, arose from a spirit of jealousy amongst certain members of it, who had formed amongst themselves certain schemes of personal aggrandizement, and were therefore unwilling to despatch any one into those quarters, in which such abundant sources presented themselves, of amassing inexhaustible riches.
The next attempt was made by Vermuyden, an opulent merchant, on the Gambia, about the year 1660 or 1665, who equipped a boat abundantly stored with bacon, beef, biscuit, rice, strong waters, and other comfortable supplies, the weight of which, however, was so great, that on arriving at the flats and shallows, the vessel could not proceed on her voyage without the greatest danger.

After navigating the shallows for some time, he arrived at a broad expanse of water, which he compared to Windermere Lake, and he now found himself on a sudden entangled in a great difficulty, owing to a number of streams flowing into this lake, and the consequent uncertainty which existed, of choosing that particular one, which might be considered the main branch or stream; and were he to ascend any other, he might find that all his labours had been spent in vain, as it might lead him to a quarter, at a great distance from those stations and towns, where the Europeans had established their commercial settlements.

"Up the buffing stream," says Vermuyden, "with sad labour we wrought," and when he had ascended further up the stream, the sailors were often obliged to strip themselves naked, and get into the water.

This was found, however, to be a most dangerous experiment, for the crocodiles and river horses showed themselves in fearful numbers, and fully inclined to treat the intruders on their rightful domain, with the most marked hostility.

Vermuyden says, they were ill pleased, or unacquainted with any companions in these watery regions, and at all events, he was convinced that his men were not very proper companions for them.
