Passage 10.35.9
Στιρίταις δέ ἐστιν ἐπὶ ὑψηλοῦ καὶ πετρώδους ἡ οἴκησις· σπανίζουσιν οὖν κατὰ τοῦτο ὕδατος θέρους ὥρᾳ· φρέατα γὰρ αὐτόθι οὔτε πολλὰ οὔτε ὕδωρ παρεχόμενά ἐστιν ἐπιτήδειον. ταῦτα μὲν δὴ λουτρά σφισι καὶ ὑποζυγίοις ποτὸν γίνεται, τὸ δὲ ὕδωρ οἱ ἄνθρωποι τὸ πότιμον ὅσον στάδια τέσσαρα ὑποκαταβαίνοντες λαμβάνουσιν ἐκ πηγῆς· ἡ δὲ ἐν πέτραις ἐστὶν ὀρωρυγμένη, καὶ ἀρύονται κατιόντες ἐς τὴν πηγήν.
The inhabitants of Stiris dwell on high, rocky ground; consequently, they suffer a shortage of water during summertime, for wells here are neither numerous nor do they provide suitable water. Such wells as they have serve only for bathing purposes and as drinking-water for their beasts of burden. The people themselves must descend approximately four stadia to fetch water for drinking from a spring, which is hewn out among the rocks; thus they go down to it and draw directly from the spring.
