Essence of Roses. See Roses Otter.

Ross of Jericho, so called because it grows in the plain of Jericho, though it did not originally grow there. It has perhaps been so named by travellers who did not know that it was brought from Arabia Petrea. Rose bushes are frequently found in the fields about Jericho; but they are of a species much inferior to those so much extolled in Scripture, the flowers of which some naturalists pretend to have in their cabinets.

"The rose shrub of Jericho (says Mariti) is a small plant, with a bushy root, about an inch and a half in length. It has a number of stems which diverge from the earth: they are covered with few leaves; but it is loaded with flowers, which appear red when in bud, turn paler as they expand, and at length become white entirely. These flowers appear to me to have a great resemblance to those of the elder-tree; with this difference, that they are entirely destitute of smell. The stems never rise more than four or five inches from the ground. This shrub sheds its leaves and its flowers as it withers. Its branches then bend in the middle, and becoming entwined with each other to the top, form a kind of globe. This happens during the great heats; but during moist and rainy weather they again open and expand.

"In this country of ignorance and superstition, people do not judge with a philosophical eye of the alternate shutting and opening of this plant: it appears to them to be a periodical miracle, which heaven operates in order to make known the events of this world. The inhabitants of the neighbouring cantons come and examine these shrubs when they are about to undertake a journey, to form an alliance, to conclude any affair of importance, or on the birth of a son. If the stems of the plants are open, they do not doubt of success; but they account it a bad omen to see them shut, and therefore renounce their project if it be not too late.

"This plant is neither subject to rot nor to wither. It will bear to be transplanted; and thrives without degenerating in any kind of soil whatever."

Roses Otter (or essential oil of), is obtained from roses by simple distillation, and may be made in the following manner: A quantity of fresh roses, for example 40 pounds, are put in a still with 60 pounds of water, the roses being left as they are with their calyces, but with the stems cut close. The mass is then well mixed together with the hands, and a gentle fire is made under the still; when the water begins to grow hot, and fumes to rise, the cap of the still is put on, and the pipe fixed; the chinks are then well luted with paste, and cold water put on the refrigeratory at top: the receiver is also adapted at the end of the pipe; and the fire is continued under the still, neither too violent nor too weak. When the impregnated water begins to come over, and the still is very hot, the fire is lessened.

ed by gentle degrees, and the distillation continued till 30 pounds of water are come over, which is generally done in about four or five hours; this rose-water is to be poured again on a fresh quantity (40 pounds) of roses, and from 15 to 20 pounds of water are to be drawn by distillation, following the same process as before. The rose-water thus made and cohabated will be found, if the roses were good and fresh, and the distillation carefully performed, highly scented with the roses. It is then poured into pans either of earthenware or of tinned metal, and left exposed to the fresh air for the night. The ottar or essence will be found in the morning congealed, and swimming on the top of the water; this is to be carefully separated and collected either with a thin shell or a skimmer, and poured into a vial. When a certain quantity has thus been obtained, the water and feces must be separated from the clear essence, which, with respect to the first, will not be difficult to do, as the essence congeals with a slight cold, and the water may then be made to run off. If, after that, the essence is kept fluid by heat, the feces will subside, and may be separated; but if the operation has been neatly performed, these will be little or none. The feces are as highly perfumed as the essence, and must be kept, after as much of the essence has been skimmed from the rose-water as could be. The remaining water should be used for fresh distillations, instead of common water, at least as far as it will go.

Rosetto is esteemed one of the pleasantest places in Egypt; it is about two miles long, and consists only of two or three streets. The country about it is most delightful and fertile, as is all the whole Delta on the other side of the Nile, exhibiting the most pleasant prospect of gardens, orchards, and corn-fields, excellently well cultivated. The castle stands about two miles north of the town, on the west side of the river. It is a square building, with round towers at the four corners, mounted with some pieces of brass cannon. The walls are of brick, cased with stone, supposed to have been built in the time of the holy war, though since repaired by Cheyk Begh. At a little distance lower, on the other side of the river, is a platform, mounted with some guns, and to the east of it are the salt lakes, out of which they gather great quantities of that commodity. At some farther distance, sailing up the river, we see a high mountain, on which stands an old building that serves for a watch-tower. From this eminence is discovered a large and deep gulph, in form of a crescent, which appears to have been the work of art, though it be now filled up, and discovers nothing but its ancient bed. Rosetto is grown a considerable place for commerce, and hath some good manufactures in the linen and cotton way; but its chief business is the carriage of goods to Cairo, all the European merchandise being brought thither from Alexandria by sea, and carried in other boats to that capital; as those that are brought down from it on the Nile are there shipped off for Alexandria; on which account the Europeans have here their vice-consuls and factors to transact their business; and the government maintains a beigh, a customhouse, and a garrison, to keep all safe and quiet.

In the country to the north of Rosetto are delightful gardens, full of orange, lemon, and citron trees, and almost all sorts of fruits, with a variety of groves of palm-trees; and when the fields are green with rice, it adds greatly to the beauty of the country. It is about 25 miles north-east of Alexandria, and 100 north-west of Cairo. E. Long. 30. 45. N. Lat. 31. 30.
