"--I became a sort of hermit," he continued; "but I did not spend my time after the usual fashion of the conventional hermit, who lives on water-cresses and reads great books with a skull to keep the pages open. I built myself a rude cabin under a great rock, and lived somewhat after the fashion of the other inhabitants of that wild region, mostly robbers and outlaws. As I had nothing which any one would want to steal, I was not afraid of them, and I could occasionally be of a little service to them, especially in the way of rude medical attendance, for which they were willing to pay me by giving me now and then some food. "I had laid in a stock of writing-materials before I went up on the mountain, and I now went to work with great enthusiasm to set down what I knew of the expedition of Xerxes, and here it was that I made the notes which were afterward so useful to Herodotus. "When the country became quieter I went down into the plains, looked over the battle-fields, and obtained a great deal of information from the villagers and country people. I stayed here nearly two years, and had a pretty hard time of it; but when I went away I took with me a very valuable collection of notes. "For many years I made no use of these notes; but being in Halicarnassus, I heard of Herodotus, who was described as a great scholar and traveler, and engaged in writing history. To him I applied without loss of time, and I made a regular engagement, working several hours with him every day. For this he paid me weekly a sum equal to about two dollars and seventy-five cents of our present money; but it was enough to support me, and I was very glad to have the opportunity of sending some of my experiences and observations down into history. It was at this time that the love of literary work began to arise within me, and in the next three or four centuries after the death of Herodotus I wrote a number of books on various subjects and under various names, and some of these, as I mentioned before, were destroyed with the Alexandrian Library.
