As a further confirmation of this, we have dated the particulars of a comet which, the Abyssinian annals say, appeared at Gondar in the month of November, in the 9th year of the reign of Yasous I. and as this comet was observed in Europe to have come to its perihelion in December 1689, and as that year, according to our account, was really the 9th of that king’s reign, no further proof of the exactness of our chronology can possibly be required. By means of these observations, counting backward to the rime of Icon Amlac, and again forward to the death of Joas, which happened in 1768, and assigning to each prince the number of years that his own historians say he reigned, I have, in the most unexceptionable manner that I can devise, settled the chronology of this country; and the exact agreement it hath with all the remarkable events, regularly and sufficiently vouched, plainly shews the accuracy of this method. If, therefore, in a few cases, I differ two or three years from the Jesuits in their first account of this country, I do not in any shape believe the fault to be mine, because there are, at all these periods, errors in point of fact, both in Alvarez and Tellez, much more material and unaccountable than the mistake of a few years; and these errors have been adopted with great confidence in the Hispania Illustrata, and some of the best books of Portuguese history which have made mention of this country. TRAVELS TO DISCOVER THE SOURCE OF THE NILE. BOOK VI. FIRST ATTEMPT TO DISCOVER THE SOURCE OF THE NILE FRUSTRATED--A SUCCESSFUL JOURNEY THITHER, WITH A FULL ACCOUNT OF EVERY THING RELATING TO THAT CELEBRATED RIVER. CHAP. I. _The Author made Governor of Ras el Feel._ I soon received an instance of kindness from Ayto Confu which gave me great pleasure on several accounts. On the south part of Abyssinia, on the frontiers of Sennaar, is a hot, unwholesome, low stripe of country, inhabited entirely by Mahometans, divided into several small districts, known by the general name of Mazaga. Of this I have often before spoken, and shall have further occasion in the sequel. The Arabs of Sennaar that are on bad terms with the governor of Atbara, fly hither across the desert to avoid the rapine and violence of that cruel tyrant. The arrival of these produces in an instant the greatest plenty at Ras el Feel; markets are held everywhere; cattle of all kinds, milk, butter, elephants teeth, hides, and several other commodities, are sold to a great amount.
