flowed like a torrent with the waves of a sea; the rocks, melted by its heat, stood up as a wall, and, for a time, it prevented the passage of Badawin, who, coming from that direction, used to annoy the citizens. Jamal Matari, one of the historians of Al-Madinah, relates that the flames, which destroyed the stones, spared the trees; and he asserts that some men, sent by the governor to inspect the fire, felt no heat; also that the feathers of an arrow shot into it were burned whilst the shaft remained whole. This he attributes to the sanctity of the trees within the Harim. On the contrary, Al-Kistlani asserts the fire to have been so vehement that no one could approach within two arrow-flights, and that it melted the outer half of a rock beyond the limits of the sanctuary, leaving the inner parts unscathed. The Kazi, the Governor, and the citizens engaged in devotional exercises, and during the whole length of the Thursday and the Friday nights, all, even the women and children, with bare heads wept round the Prophet’s tomb. Then the lava current turned northwards. (I remarked on the way to Ohod signs of a lava-field.) This current ran, according to some, three entire months. Al-Kistlani dates its beginning on Friday, 6 Jamadi al-Akhir, and its cessation on Sunday, 27 Rajab: in this period of fifty-two days he includes, it is supposed, the length of its extreme heat. That same year (A.H. 654) is infamous in Al-Islam for other portents, such as the inundation of Baghdad by the Tigris, and the burning of the Prophet’s Mosque. In the next year first appeared the Tartars, who slew Al-Mu’tasim Bi’llah, the Caliph, massacred the Moslems during more than a month, destroyed their books, monuments, and tombs, and stabled their war-steeds in the Mustansariyah College. [FN#4] In this part of Al-Hijaz they have many names for a pass:—Nakb, Saghrah, and Mazik are those best known. [FN#5] This is the palm, capped with large fan-shaped leaves, described by every traveller in Egypt and in the nearer East. [FN#6] The charge for a cup of coffee is one piastre and a half. A pipe-bearer will engage himself for about £1 per mensem: he is always a veteran smoker, and, in these regions, it is an axiom that the flavour of your pipe mainly depends upon the filler. For convenience the Persian Kaliun is generally used. [FN#7] A day’s journey in Arabia is generally reckoned at twenty-four or twenty-five Arab miles. Abulfeda leaves the distance of a Marhalah (or Manzil, a station) undetermined. Al-Idrisi reckons it at thirty miles, but speaks of short as well as long marches. The common literary measures of length are these:—3 Kadam (man’s foot) = 1 Khatwah (pace): 1000 paces = 1 Mil (mile); 3 miles = 1 Farsakh (parasang); and 4 parasangs = 1 Barid or post. The “Burhan i Katia” gives the table thus:—24 finger breadths (or 6 breadths of the clenched hand, from 20 to 24 inches!) = 1 Gaz or yard; 1000 yards = 1 mile; 3 miles = 1 parasang. Some call the
