Rh which we had left in the morning, and the undulated grounds at which we had now arrived.

But at length we perceived the tracks of living beings, and soon after saw the huts of Colonel Rees's negroes. Scarcely covild ever African traveller have approached the city of Timbuctoo with more excited cu- riosity than we felt in approaching this plantation. Our Indian horses seemed to participate in our joy, and trotted at a smart rate towards the principal building, at the door of which we leaped from our saddles, just as the sun was withdrawing his ruddy light. Colonel Rees was at home, and received us with great kindness. Refreshments were immediately placed before us, and we spent the evening in agreeable conversation. The next day I walked over the plantation, and examining the country around, found the soil of good quality, it having been reclaimed from swampy ground of a black colour, rich and very productive. The greater part of the cultivated land was on the borders of a lake, which communi- cates with others, leading to the St John's River, distant about seven miles, and navigable so far by vessels not exceeding fifty or sixty tons. After breakfast, our amiable host shewed us the way to the celebrated spring, the sight of which afforded me pleasure sufficient to counter- balance the tediousness of my journey.

This spring presents a circular basin, having a diameter of about sixty feet, from the centre of which the water is thrown up with great force, although it does not rise to a height of more than a few inches above the general level. A kind of whirlpool is formed, on the edges of which are deposited vast quantities of shells, with pieces of wood, gravel, and other substances, which have coalesced into solid masses having a very curious appearance. The water is quite transparent, although of a dark colour, but so impregnated with sulphur, that it emits an odour which to me was highly nauseous. Its surface lies fifteen or twenty feet below the level of the woodland lakes in the neighbourhood, and its depth, in the autumnal months, is about seventeen feet, when the water is lowest. In all the lakes, the same species of shells as those thrown up by the spring, occur in abundance, and it seems more than probable that it is formed of the water collected from them by infiltration, or forms the subterranean outlet of some of them. The lakes themselves are merely reservoirs, containing the residue of the waters which fall during the rainy seasons, and contributing to supply the waters of the St John River, with which they all seem to communicate by similar means. This spring pours its waters
