Note 297 — Chapter VI · THE ÆOLIDS, OR SONS AND DAUGHTERS OF ÆOLUS.

See the description of these channels or Katabothra in Colonel Leake’s Travels in Northern Greece, vol. ii. c. 15, p. 281-293, and still more elaborately in Fiedler, Reise durch alle Theile des Königreichs Griechenlands, Leipzig, 1840. He traced fifteen perpendicular shafts sunk for the purpose of admitting air into the tunnel, the first separated from the last by about 5900 feet: they are now of course overgrown and stopped up (vol. i. p. 115).

Forchhammer states the length of this tunnel as considerably greater than what is here stated. He also gives a plan of the Lake Kôpaïs with the surrounding region, which I have placed at the end of the second volume of this History. See also infra, vol. ii. ch. iii. p. 391.
