The trade last year was greatly increased by the unusually large demand for olive-oil from all parts, and there is no doubt that, under a more liberal Government, the commerce might be developed to a vast extent. RABAT. The principal goods imported at Rabat are, alum, calico of different qualities, cinnamon, fine cloth, army cloth, cloves, copperas, cotton prints, raw cotton, sewing cotton, cutlery, dimity, domestics, earthenware, ginger, glass, handkerchiefs (silk and cotton), hardware, indigo, iron, linen, madder root, muslin, sugar (refined and raw), tea, and tin plate. The before-mentioned articles are imported partly for consumption in Rabat and Sallee, and partly for transmission into the interior. The value of different articles of produce exported at Rabat during the last five years amounts to £34,860 1_s_. There can be no doubt that the imports and exports at Rabat would greatly increase, if the present high duties were reduced, and Government monopolies abolished. Large quantities of hides were exported before they were a Government monopoly: now the quantity exported is very inconsiderable. MAZAGAN. _Goods Imported_.--Brown Domestics, called American White, muslins, raw cotton, cotton-bales, silk and cotton pocket-handkerchiefs; tea, coffee, sugars, iron, copperas, alum; many other articles imported, but in very small quantities. A small portion of the importations is consumed at Mazagan and Azimore, but the major portions in the interior. The amount of the leading goods exported in 1855 was:--Bales of wool, 6,410; almonds, 200 serons; grain, 642,930 fanegas. No doubt the commerce of this port would be increased under better fiscal laws than those now established. But the primary and immediate thing to be looked after is the wilful casting into the anchorage-ground of stone-ballast by foreigners. British masters are under control, but foreigners will persist, chiefly Sardinian masters. THE END [1] The predecessor of Muley Abd Errahman.
