96 THE EMPTY QUARTER the great King of Wabar. That one at least of the old man- sions—and perhaps the greatest—was destroyed by fire in some form is rendered certain by the ashes that have given it its name, Umm al Ramad,1 but we need not follow the modern story-tellers in the highest flights of their fancy which attri- butes to 'Ad the use of gunpowder for the destruction of the enemy stronghold!

My companions would have preferred to remain on the water at Mushammara but I was anxious to select for my astronomical observations a site as near as possible to Major Cheesman's camp of 1924. The exact site of his work I failed to determine as all our researches failed to discover the 40-foot well of which he speaks,2 though the single mud- built dwelling of eight years ago was now swollen to the dimensions of a hamlet of six houses, of which the largest was that of the late Hamad ibn Muradhdhaf and another the local mosque.

Its depth was not more than 10 feet. The first day we spent in exploring the oasis southward from Mushammara with the result that we did not arrive at the ruins of Qasr Umm al Ramad till after dark.
