During the winter, Captain Billings, who had formerly been assistant-astronomer in Cook’s expedition, but was now in the Russian service, arrived at Yakutsk. He was surprised to meet Ledyard in the heart of Siberia; but having a disinclination to connect himself with any person not favoured by fortune, evinced no disposition to be of the least service to him. It has even been suspected, and not altogether without probability, that Billings had some share in bringing about the unfortunate catastrophe which terminated Ledyard’s travels in Siberia. However, previous to this event, he invited his old shipmate to accompany him to Irkutsk, whither they proceeded up the frozen Lena upon sledges. Here, soon after their arrival, Ledyard was arrested as a French spy, placed in a kibitka with two hussars, and hurried back with incredible speed to the frontiers of Poland, where he was dismissed, with the strictest injunctions never again to enter the dominions of Russia. It would now be idle to inquire into the motives which urged the old profligate she-despot into the commission of this act of flagrant injustice. She had no doubt been told (Dr. Clarke suspects by Billings) that his success might be some way or another detrimental to the interests of her commerce; and, without consideration or inquiry, perhaps in some furious fit of rage or drunkenness, she issued the order for his recall, which was executed with no less barbarity than it was issued. How the poor victim found his way from Poland to London Heaven only knows. His sufferings, he says, were too great to be disclosed. However, he had scarcely reached London before a proposal was made to him to travel for the African Association, which, wretched as he was, he was but too happy to accept. The object of his mission, like that of many other brave and adventurous men who have perished in the same track, was to explore the centre of Africa from Sennaar westward, “in the latitude and supposed direction of the Niger.” For this purpose he proceeded to Egypt; but having ascended the Nile to Cairo, and made every necessary preparation for travelling with a caravan to Sennaar, he was suddenly attacked by a bilious disorder, and was poisoned by the vitriolic acid which he took as a remedy, in the month of November, 1788.
