At this part of the conversation I put in my word, and said, "Really, gentlemen, you are all mistaken; the far-famed Derveish you mention is a Frenchman, his real name is Tollemache, and I know him well." It was not a mere smile of incredulity with which they listened. The remark I had made, while it received not the least credit, excited unpleasant feelings, and a friend near me whispered that it was better to abstain from the subject.
The following is a short history of this remarkable individual, who has attained such a perfection in the languages and manners of the natives of Asia as to deceive the most learned.
Mons. Tollemache, the son of a Dragoman at Constantinople, was many years ago recommended to Mr. Warren Hastings, who patronised him; but a quarrel, in which he was involved, at Calcutta, led to his leaving that city and going to the north-western part of India, from whence he went into the countries of Cabool, Khorassan, and Persia, and was lost trace of by his European friends for twelve years. His latter name in Persia was the Derveish Abdûlla, under which he became renowned for his piety and learning. He had officiated as first reader of prayers[19] before the late King, who honoured him with his favour. He came to Abusheher, from whence he went to Surat, where, after his overtures of service to the English government had been refused, he proceeded to the Isle of France, and is mentioned in Lord Wellesley's notes as the person employed there with Tippoo Sultan's Ambassadors. On proceeding afterwards to the Red Sea he was made prisoner by Admiral Blanket, and sent to Bombay, where I became acquainted with him at the house of a friend with whom he resided.
The memory of Tollemache was stored with rare Persian poems and songs: his conversation was, from his various knowledge, very entertaining. Of his power to assume any Asiatic character, the following anecdote will suffice. He had been dilating on his success in deceiving natives of the countries through which he passed, and observed me to be rather incredulous. I had not remarked his leaving the room some minutes before I did, but, when driving out of the gate, I was so annoyed by the importunities of a Mahomedan mendicant, who was almost naked, that I abused him, and threatened to use my whip, if he did not desist, when the fellow burst into a fit of laughter, and asked me if I so soon forgot my acquaintances? I could hardly credit my eyes and ears on recognising Tollemache; and the recollection of this occurrence prevented me saying more to my friends at the Shaikh's party, whom I left in the belief that the holy Abdûlla was a saint upon earth.
The first march from Abusheher we had to pass over a desert plain of considerable extent, on which I amused myself by watching narrowly the various changes, as we were near or remote from it, of that singular vapour, called by the French Mirage, and by the Arabs and Persians Sirab.
The influence of this vapour in changing the figure of objects is very extraordinary; it sometimes gives to those seen through it the most fantastical shapes; and, as a general effect, I think it always appears to elevate and make objects seem much taller than they really are. A man, for instance, seen through it at the distance of a mile and a half upon the level plain appears to be almost as tall as a date tree.
Its resemblance to water is complete, and justifies all the metaphors of poets, and their tales of thirsty and deluded travellers.
The most singular quality of this vapour is its power of reflection. When a near observer is a little elevated, as on horseback, he will see trees and other objects reflected as from the surface of a lake. The vapour, when seen at a distance of six or seven miles, appears to lie upon the earth like an opaque mass; and it certainly does not rise many feet above the ground, for I observed, that while the lower part of the town of Abusheher was hid from the view, some of the more elevated buildings, and the tops of a few date trees, were distinctly visible.
Among the presents for his majesty of Persia were two light field-pieces, to which were attached a select detachment of horse-artillery. Great care was taken to equip this party in the best style; and as they had a difficult march to perform, they were sent in advance, under the tall officer who has been already mentioned. Our third stage to Dalkhee was so rough and stony, that we were alarmed lest we should hear bad accounts of their progress; but our fears were all dissipated by the reports of the villagers.
