Note 562 — Chapter IV · Turkomania and the Turkomans
Reading edition
The desert wells are termed urpa when shallow, and kuduk or kuyu when they are deep and afford a constant supply. The only sign of their existence is the tracks converging on them from every quarter. They are mere holes, without kerb or fencing, and the sides are roughly shored up by the branches of desert shrubs (ibid. p. 299).
