_Coloquintida_, called by the Arabs El Hendal, is found along the coast, on the sandy shore above the high water mark from Agadeer to Wedinoon, an extent of about two hundred miles: it had never been imported into this country till last year, by myself, when it sold at 3_s._ 8_d._ per lb. Throughout this fertile country roses, and various beautiful flowers which are carefully reared in hot houses with us, grow spontaneously in the plains: of these I have seen in Temsena, and about Rabat, and in Suse, lupins, jonquils, wall-flowers and hyacinths of various colours and exquisite fragrance (of the latter there is a beautiful kind, being a Spanish brown, inclining to scarlet.) The roses about Marocco grow in the streams and ditches. At Tafilelt they have a powerful fragrance: it is from the leaves of the Worde Fillelly, or Tafilelt rose, that the celebrated _Attar_ of roses (commonly called _Otto_ of roses) is extracted: the word _Attar_ is an Arabic word signifying a distillation or filtration.[118] _Surnag._—This vegetable grows on the declivities of the Atlas mountains. The Moors drink a decoction of it for the purpose of inciting them to venereal pleasure. _Truffles._—This root, called by the Arabs Terfez, is somewhat similar to the potatoe, and about the size of a lemon; it grows in sandy places, near the surface of the earth, where it is discovered by the light soil appearing swelled and cracked. It is not planted, but grows spontaneously; some are black, others white, but the former are the best; both, however, have a black rind, which does not peel off like that of a potatoe, but is cut or pared like that of an apple. The Arabs, Moors, Shelluhs, and Jews, equally prize the truffle; it is therefore in great demand, and used in all made dishes, and is a very delicate, nutritious, and wholesome food: they are also highly stimulating, on which account they are more esteemed among this amorous people than for their delicate taste; they are particularly palatable with wine, and often introduced in the dessert. They are very good boiled in water or in steam. In Suse, Abda, and Bled-el-jerrêde, they are found in great abundance. The season for them is March, when the storms of thunder prevail. After a storm, the people repair to the sandy plains, dig them up, and bring them to the towns, where, being in great demand, they sell at a costly price. GUMS, OILS, &c.
