Tacitus says, that this tree was so averse to iron that it trembled upon a knife being laid near it, and some pretend the incision should be made by ivory, glass, or stone. There is no doubt but the more attention there is given to it, and the cleaner the wound is made, the better this balsam will be. It is now, as it probably ever has been, cut by an ax, when the juice is in its strongest circulation in July, August, and beginning of September. It is then received into a small earthen bottle, and every day’s produce gathered and poured into a larger, which is kept closely corked. The Arabs Harb, a noble family of Beni Koreish, are the proprietors of it, and of Beder, where it grows. It is a station of the Emir Hadje, or pilgrims going to Mecca, half way between that city and Medina. Some books speak of a white sort brought by the caravans from Mecca, and called Balsam of Mecca, and others a balsam called that of Judea, but all these are counterfeits or adulterations. The balsam of Judea, which I have already mentioned, was long ago lost, when the troubles of that country withdrew the royal attention from it; but, as late as Galen’s time, it not only existed, but was growing in many places of Palestine besides Jericho, and there is no doubt but it is now totally lost there. When Sultan Selim made the conquest of Egypt and Arabia in the year 1516, three pound was then the tribute ordered to be sent to Constantinople yearly, and this proportion is kept up to this day. One pound is due to the governor of Cairo, one pound to the Emir Hadje who conducts the pilgrims to Mecca, half a pound to the basha of Damascus, and several smaller quantities to other officers, after which, the remainder is sold or farmed out to some merchants, who, to increase the quantity, adulterate it with oil of olives and wax, and several other mixtures, consulting only the agreement of colour, without considering the aptitude in mixing; formerly we were told it was done with art, but nothing is easier detected than this fraud now.
