The isle of Serendib[Footnote: Geographers place it on this side of the line, in the first climate.] is situate just under the equinoctial line; so that the days and nights there are always twelve hours each, and the island is eighty[Footnote: The eastern geographers make a parasang longer than a French league.] parasangs in length, and as many in breadth. The capital city stands in the middle of a fine valley formed by a mountain, in the middle of the island, which is the highest in the world. It is seen three days sail off at sea. There are rubies and several sorts of minerals in it, and all the rocks for the most part emerald, a metal line stone made use of to cut and smooth other precious stones. Here grow all kinds of rare plants and trees, especially cedars and cocoas. There is also pearl-fishing in the mouth of its river, and in some of its vallies there are found diamonds. I made, by way of devotion, a pilgrimage to the place where Adam was confined after his banishment from Paradise, and had the curiosity to go to the top of it. When I came back to the city, I prayed the king to allow me to return to my country, which he granted me in the most obliging and honourable manner. He would needs force a rich present upon me; and when I went to take leave of him, he gave me one much more considerable, at the same time charging me with a letter for the commander of the faithful, our sovereign, and said, I pray you give this present from me, and this letter, to Caliph Haroun Alraschid, and assure him of my friendship. I took the present and letter in a very respectful manner, and promised his majesty punctually to execute the commission with which he was pleased to honour me. Before I embarked, this prince sent to seek for the captain and the merchants who were to go with me, and ordered them to treat me with all possible respect.
