Note 044
In Persia, the prince of the waters is an officer of state. The number of wells and subterraneous channels is much diminished, and with it the fertility of the soil: 400 wells have been recently lost near Tauris, and 42,000 were once reckoned in the province of Khorasan (Chardin, tom. iii. p. 99, 100. Tavernier, tom. i. p. 416.)]
