Note 40 — THE VOYAGE OF NEARKHOS.

All inquirers have agreed in identifying the Kolaka of Ptolemy, and the sandy island of Krokola where Nearchus tarried with his fleet, for one day, with a small island in the bay of Karâchi. Krôkala is further described as lying off the mainland of the Arabii. It was 150 stadia, or 17¼ miles, from the western mouth of the Indus,—which agrees exactly with the relative positions of Karâchi and the mouth of the Ghâra river, if, as we may fairly assume, the present coast-line has advanced five or six miles during the twenty-one centuries that have elapsed since the death of Alexander. The identification is continued by the fact that the district in which Karâchi is situated is called Karkalla to this day. Cunningham Geog. of An. India, I. p. 306.
