The interesting and scholarly volume of Mr. McCrindle, recently published by A. Constable and Co., invites an attempt to settle more precisely the line on which Alexander reached the bank of the Indus. Mr. McCrindle loses the clue when Alexander reaches Nikaia. This place he is inclined to fix somewhere near Bagraâm, and he thinks that a part of Alexander's troops then passed through the Khaibar to the district called Peukelaôtis, somewhere near Hashtnagar on the river Landai. The formation of the country makes such a course improbable; but Mr. McCrindle admits that the geography of Kâfiristân, Chitrâl, and Swât is too little known to enable him to trace the course of the Macedonian army at this point. I will here try to supply that information.
