Herodotus891 and other writers trifle very much when they introduce into their histories the marvellous, like (an interlude of) music and song, or some melody; for example, in asserting that the sources of the Nile are near the numerous islands, at Syene and Elephantina, and that at this spot the river has an unfathomable depth. In the Nile there are many islands scattered about, some of which are entirely covered, others in part only, at the time of the rise of the waters. The very elevated parts are irrigated by means of screw-pumps.
