country we passed to-day, for about ten miles on the eastern bank of the
river, is mostly covered by sand; that on the western bank is beautiful.
During the whole of the afternoon, however, the country we passed, on
both banks, can be surpassed by none in the world for fertility; the
appearance of numerous water-wheels and large plantations of durra
and cotton, showed us that this fine territory was improved by a
considerable population. The face of the country continues still
the same, an immense and fertile plain, bounded by the horizon
and intersected by the windings of the river Nile. We have seen no
considerable eminence for many days, except that on which stands the
old city of Dongola, which we passed yesterday; it is a fine military
position.

2d of Rebi. The wind to-day was right ahead, owing to the curious fact
that the river here makes an eccentric bend to the left, toward the
north-east, and presents itself as coming from that quarter instead of
from the south or south-west, as usual hitherto.[18] The Rais attempted
to advance by cordelling the boat; but the force of the wind and current
prevented the boatmen from gaining more than two or three miles along
the coast of the island, where we landed yesterday. We were therefore
obliged to pass a great part of this day and all night by the shore. The
island is about twenty miles long and very beautiful; it is called, as I
have been repeatedly informed, "Argo."

3d of Rebi. We were obliged still to continue fast by the shore till
noon, when the wind abating, the boat advanced about two miles by the
help of the cordel, so far as to arrive at a small bend in the river,
which brought the wind a little in our favor, so as to pass by its aid
to the other side, in the hope, if the wind continued the same on the
morrow, to profit by it and proceed. We arrived a little before sun set,
