The Omda and his attendants carry out the operations with the utmost care and solemnity, and have the most touching faith in the accuracy of their results. Apart, however, from errors in the gauges and scales used, and from the want of provision of a free fall on the downstream side of the weir, the fact that the velocity of the stream is entirely left out of account is sufficient to give the qirat a very variable value, low for small and high for large streams, the result being that the small wells are being taxed at about 50 per cent. higher rates than the large ones. In order to ascertain the average value of the qirat for streams of different size, I arranged with Mr. Patterson, who at the time was the Government Representative in Kharga, to send the Omda to headquarters and instruct him to measure a number of new bores belonging to the Corporation of Western Egypt, as these bores, being cased and provided with proper outlet valves, lend themselves to exact measurement better than the majority of the native-owned wells. The Omda employed the ordinary local native method just described, while I, using a tank of known capacity and a reliable stop-watch, made direct measurements immediately afterwards. The results obtained show that below 2 the qirat has a value of 22 gallons a minute; from 2 to 4 of 26 gallons a minute; and from 5 to 6 of 38 gallons a minute. The annual tax levied on the water amounts to 50 piastres (about 10s. 3d.) per qirat. If the average value of the qirat be taken at 25 gallons per minute, the tax works out at approximately 1s. for every 6,000 cubic metres of water. Looked at from another point of view, it may be considered that the tax amounts to about 1s. 6d. an acre, as with every qirat of water the native cultivator in the oasis will annually raise about two acres of rice and five of wheat or barley. The total revenue derived by the Government from the oasis, by taxes on date-palms and water, amounts to a little over £1,000 per annum. My old friend Sheikh Mustapha, who for more than twelve years has been Omda of Kharga village, was very anxious to know the results of the comparative measurements made on the bores. He professed himself as surprised at the difference in the results, but emphatically refused to entertain the possibility of there being any error in his measurements, made by so old-established a method. Although he was far too polite to so express himself in words, I felt that the old gentleman had the utmost contempt for my method of well measurement. With the exception of the Dakhla peasants, the inhabitants of the oases differ entirely from the fellahin of the Nile Valley. According to Brugsch, the original inhabitants were Libyan (Berber) tribes, but after annexation to Egypt, there was considerable immigration from Nubia and other parts of the Nile Valley. Nevertheless, in the oasis of Kharga the physiognomic type of the Berber race is still predominant.
