I shall write to you once more before I set out from hence, which I hope will be in three weeks. If the departure and arrival of the caravans, were as well regulated in Africa, as they are in Syria, this vast continent would soon be explored. But the difficulties and delays are great, and can only be overcome by patience. The plague is said to have ceased at Cairo, but it still continues in some parts of Lower Egypt, after having almost depopulated Alexandria and Damietta. It had reached a village only two hours distant from here, but made no farther progress. But great fears are entertained that it will increase and spread next winter, over the whole country, which is generally the case whenever it has not completely subsided towards the end of June. _Extract of a letter from Esne, October 14th,_ 1813. The great Djelabe traders from Sennaar who have just arrived here, have at length put an end to the impediment caused by the chief of Mograt, by killing him and his principal men in his own house at Mograt. But another difficulty has occurred. There is a great scarcity of provisions in the Nile countries, from Gous up to Sennaar, occasioned by the locusts, who devoured entirely the last winter crops. The envoys sent last year by Mohammed Aly, to the King of Sennaar, who have returned with the late caravans, describe the state of the inhabitants as most deplorable; they kill each other for a measure of Dhourra, and neither law nor government is any more attended to. Under such circumstances the caravans assembled at Daraou, in the neighbourhood of Assouan, have not thought proper to leave Egypt, where every kind of provision is at the lowest price. They have wisely resolved to defer their departure until the new Dhourra grain should have been reaped in the southern countries, when as the inundation of the Nile has been very copious this year, plenty will have returned to those districts. I shall thus start in their company in about three weeks from this time, and have little doubt, provided I remain in good health, that I shall reach Massuah in safety, by taking my road straight across the mountains from Damer towards Massuah. From Massuah I mean to cross over to the Arabian coast, and to return to Cairo by the Hedjaz; I hope the Committee of the African Association will not object to this extension of my travels. I keep my ultimate object well in view, and after my return to Cairo, I shall be ready to put it in execution. But I think that the discovery of the interior parts of Nubia is well worth a year’s labour and the expense attending it. My journey through Arabia may probably qualify me better than any thing else, to future perilous travels in the Mohammedan world, nor will it, I hope, be devoid of some advantages to science.
