[Footnote 65: Probably these great hurricanes are not uncommon on the Euphrates. In the year 1831 a gale sent Colonel Chesney's "little vessel to the bottom of the river;" but a still greater calamity befel the Tigris steamer in the Euphrates expedition which was under the command of Colonel Chesney, in May 1836. A little after one P.M. a storm appeared bringing with it clouds of sand from the west-north-west. The two steam-boats the Tigris and the Euphrates were then passing over the rocks of Es-Geria, which were deeply covered with water. The Euphrates was safely secured; but the Tigris, being directed against the bank, struck with great violence; the wind suddenly veered round and drove her bow off; "this rendered it quite impossible to secure the vessel to the bank, along which she was blown rapidly by the heavy gusts; her head falling off into the stream as she passed close to the Euphrates, which vessel had been backed opportunely to avoid the concussion." The Tigris perished in this violent hurricane and twenty men were lost in her. The storm lasted about eight minutes. Colonel Chesney escaped by swimming to the shore just before the vessel went down: he was fortunate "to take a direction which brought him to the land, without having seen anything whatever to guide him through the darkness worse than that of night."--"For an instant," says Colonel Chesney after getting to land, "I saw the keel of the Tigris uppermost (near the stern); she went down bow foremost, and having struck the bottom in that position, she probably turned round on the bow as a pivot, and thus showed part of her keel for an instant at the other extremity; but her paddle beams, floats, and parts of the sides were already broken up, and actually floated ashore, so speedy and terrific had been the work of destruction." (Letter from Colonel Chesney to Sir J. Hobhouse, 28th May, 1836; Euphrates Expedition Papers printed by order of the House of Commons, 17th July, 1837.) Ammianus Marcellinus (xxiv. 1) speaks of a violent storm at Anatha (Annah) on the Euphrates, during the expedition of the Emperor Julian. It blew down the tents and stretched the soldiers on the ground.] [Footnote 66: A place struck with lightning was considered religious (religiosus), that is, it could no longer be used for common purposes. "The deity," says Festus (v. _Fulguritum_), "was supposed to have appropriated it to himself." Dion Cassius (40. c. 17, &c.) gives the story of the passage of the river. The eagle, according to him, was very obstinate. It stuck fast in the ground, as if it was planted there; and when it was forced up by the soldiers, it went along very unwillingly.
