H.T. Colebrooke, Esq., in a paper inserted in the Asiatic Transactions, vol. xii. asserts, that it requires an elevation of 28,000 feet, for an object to be visible at the distance of 200 94 geographical miles; now 245 English miles are equal to 211-1/2 geographical miles; consequently, if Mr. Colebrooke be correct, the summit of Atlas, east of Marocco and Dimenet, which is seen at a distance of 211-1/2 geographical miles, must be 29,610 feet high, or above five miles and a half.
Again, the chain of Atlas in Lower Suse, which lies east of Elala, and which is constantly covered with snow, is situated three days' journey, horse travelling, east-south-east from Elala, in Lower Suse; Elala is three days' journey from Santa Cruz, horse travelling, making together 180 miles: add for distance from the foot of the Elala mountains to the snow, 60 miles, and the Atlas in Lower Suse will be seen at the distance of 240 miles, or 207 geographical miles.
Thus, from Santa Cruz to the } foot of the Atlas mountains, in the} 180 miles. district of Elala, in Lower Suse }
Add for distance from the foot } of the Elala mountains to the } 60 snow } --- So that the Atlas in Lower Suse, } being seen at a distance of } 240
Or 207 geographical miles, must have an altitude of 28,980 feet.
On the north side of the city of Marocco is a gate called _Beb El Khummes_, and near it is held, every Thursday, a market called soke _El Khummes_; at which immense quantities of horses, camels, mules, asses, oxen, sheep, goats, wheat and barley are sold; oils, gums, 95 almonds, dates, raisins, figs, bees' wax, honey, skins, &c. &c. &c.; also, slaves, male and female. Such a horse as would cost in London 50_l._, sells here for 50 dollars; a good mule sells for the same, viz. 50 dollars; a bull, 12 dollars; a cow, 15 dollars; sheep, a dollar and a half, each; a goat, a dollar. Very fine large grained wheat, which increases one-fifth in the grinding, sells at one dollar per saa, or about half a dollar per Winchester bushel. The slaves are conducted through the market by the auctioneer (_delel_), who exclaims, occasionally, (_khumseen reeal aal zeeada_, i.e.) "50 dollars on the increase," till he finds no one will advance; when he goes to the owner and declares the price offered; the owner then decides if he will sell or not; if he sells, the money is paid immediately, but if not, he takes his slave away with him, and tries him again the next market-day, or waits in expectation that this wretched article of trade will rise in value.
