'These persons, on their return,' continued Beltran, 'reported that they had followed the river till they came to a large mountain of perpendicular rocks, which it was impossible to climb, and over these rocks fell the water. And it seemed to them that on the top of this mountain were many trees; and they saw strange wild beasts, such as lions, elephants, and other sorts, which came to gaze at them. And, not daring to advance further, they returned to the sultan.'

'And this is all that is known?' said Walter.

'Yes,' replied Beltran. 'Where the Nile enters Egypt, it spreads in branches over the plain. One of them flows to Damietta; a second to Alexandria; a third to Tunis; and a fourth to Rexi. About St. Remy's Day it expands itself into seven branches, and thence flows over the plains. When the waters retire, the labourers appear and till the ground with ploughs without wheels, and then sow wheat, barley, rice, and cumin, which succeed so well that nowhere are finer crops.'

'And whence,' asked Walter, 'comes this yearly increase of water?'

'I cannot tell, except that it comes from God's mercy. Some say that this overflowing is caused by heavy rains in Abyssinia; but many Arabs believe that a drop of dew falls into the river, and causes the inundation; and some declare they have seen it fall, like a star. The night when it falls is called the "drop-night." But certain it is that, were it not to happen, Egypt, from the great heat, would produce nothing; for, being near the rising sun, it scarcely ever rains, save at very long intervals.'

'Of a truth,' observed Walter, 'all this sounds strange to English ears.'

'Where the river enters Egypt,' continued Beltran, 'there are expert persons, who may be called the fishermen of this stream, and who, in the evening, cast their nets into the water, and in the morning frequently find many spices in them, such as ginger, cinnamon, rhubarb, cloves, lignum-aloes, and other good things, which they sell by weight.'

'But how come the spices into the water?' enquired Walter.

'Well, it is the belief of the country that they come from the terrestrial paradise, and that the wind blows them down from these fine trees, as, in your forests, the wind blows down the old dry wood. But such is mere surmise, albeit widely credited.'

'And the water of the Nile is deemed sweet to the taste?' said Walter.
