and that Daman's Negro was about to depart for Jarra; but he said he had
no doubt, if I would stop a little, that he could persuade the latter to
accompany us. I waited accordingly, and in about an hour the boy returned
with the Negro; and we continued travelling over a sandy country, covered
chiefly with the _Asclepias giganteo_, until mid-day, when we came to a
number of deserted huts; and seeing some appearances of water at a
distance, I sent the boy to fill a soofroo; but as he was examining the
place for water, the roaring of a lion, that was probably on the same
pursuit, induced the frightened boy to return in haste; and we submitted
patiently to the disappointment. In the afternoon we reached a town
inhabited chiefly by Foulahs, called Samamingkoos.

Next morning (March 4th) we set out for Sampaka, which place we reached
about two o'clock. On the road we observed immense quantities of locusts;
the trees were quite black with them. These insects devour every
vegetable that comes in their way, and in a short time completely strip a
tree of its leaves. The noise of their excrement falling upon the leaves
and withered grass, very much resembles a shower of rain. When a tree is
shaken or struck, it is astonishing to see what a cloud of them will fly
off. In their flight they yield to the current of the wind, which at this
season of the year is always from the north-east. Should the wind shift,
it is difficult to conceive where they could collect food, as the whole
of their course was marked with desolation.

Sampaka is a large town, and, when the Moors and Bambarrans were at war,

loss, though the King of Bambarra was afterwards obliged to give up this,
and all the other towns as far as Goomba, in order to obtain a peace.
Here I lodged at the house of a Negro who practised the art of making
gunpowder. He showed me a bag of nitre, very white, but the crystals were
