We now return to the canal of Mahmoudieh. Fifteen years ago there was a scarcity of grain in Europe, but a great abundance in Egypt, and the merchant-sovereign had an opportunity of realizing an extremely handsome profit on the products of his soil; but the Nile happened at that season to be unusually low, and vessels found it so difficult to load at the mouth of the river, that his harvest of gain was in a great measure lost. He then conceived the idea of a canal to unite the river with the secure and excellent harbor of Alexandria. With him there is but a short interval between planning and executing. He sent his soldiers into the country with requisitions on the various governors for men, according to the size of their villages or districts. The poor natives were hunted up, and being fastened to long poles by iron collars around the neck, forty to a pole, were thus driven down to the line marked out by his engineer, and there set to work. Mr. Gliddon, who saw the work in progress, informed me that there were 150,000 men employed upon it at one time. In six months the canal was completed, with the exception of a little masonry, and was opened for use. It is sixty miles in length, ninety feet wide, and eighteen in depth, including six feet of water. The workmen had no tools, except a few hoes to break the hard upper crust: when this had been done, they scraped the earth together with their fingers, formed it into balls, and passed them by hand to the sides of the canal, a large portion of the wet mass often escaping between their hands while on the way. Exposed to the sun, and without shelter at night, and probably without sufficient food, disease crept in among them; and I was credibly informed that during the digging, 30,000 of the workmen perished: their bodies, as soon as life was extinct, were tossed upon the growing heaps of earth at the side, and this was their burial. The canal follows the line of that dug by Alexander the Great, till near Damanhour, when it unaccountably makes a great bend to the south. The engineer has made another blunder in the grading, in consequence of which it is too shallow to be navigable during the two months when the river is at the lowest.
