Good quality potatoes, such as are marketed in England, are rarely found in Egypt. The crop is generally grown from "seed" imported from France and Italy, and a sandy soil is chosen. Two crops, however, can be taken from the land per annum. The first is planted in October, and should be ready for lifting in the beginning of February, a period of five months; the second, planted in February, is ready for harvesting in June--the duration of time for the crop to be on the land, one hundred and ten days. It sounds novel to a British grower to speak of a winter and a summer crop of potatoes, two crops in the year; but this is so, and the winter may yield three tons per acre, while the summer produces five to six; while the current price per ton returned to the grower is about seven pounds. As this is the most popular of vegetables, and the demand always so great for good, well-grown new potatoes, experiments have been tried for raising these in the neighbourhood of Cairo and sending them packed in boxes to arrive in England, when they would be eagerly bought up in the market as luxuries, at the beginning of March. Here are the returns of the experiment. From fifteen to eighteen pounds per ton were realised; carriage, freight, and other expenses amounted to three pounds per ton, leaving a margin of profit over the price in Egypt of from five pounds to eight pounds sterling. Enough this to make the Delta worthy the name of a land of promise, and especially more so when it can be, and is, announced that it is a country where there is no potato disease. In exceptional cases, however, there is the drawback of cold weather, which retards the growth of the winter crop. Another objection is that all the seed potatoes--and these are heavy of freight--have to be imported, as storing throughout the summer is impracticable. It is only fair to say, however, on behalf of our good old mealy friend, the familiar object of every man's table, that in his guise of a foreigner--an African--he will be much better if he is let alone and not subjected to the tricks of trade, which recoil upon and tend to spoil his character. For in the harvesting of the crop a bad practice has arisen with the Egyptian market gardener, who generally carries on his operations in the neighbourhood of some irrigation canal connected with the Nile, where he has, so to speak, abundance of conserved water always on tap ready to give his fields a heavy watering. This he bestows upon his potatoes just before turning them out of the ground, as he finds that it greatly increases the weight of the tubers; but it spoils their quality, and makes them what a Londoner calls "waxy," and a north countryman "sad."
