In the midst of the elemental disorder, they became aware of a hoarse growling sound; the waters were violently agitated, and a great crest of foam rapidly advanced towards their feeble barks. In a few moments it was upon them. It swept clean over the voyagers and their canoes, and those of the latter which had been carelessly moored were borne down the rushing tide. At first an indescribable disorder prevailed; cries of distress rose in every direction; the canoes dashed violently against one another, or came into collision with uprooted trunks floating on the surface of the storm-tossed waters. Fortunately, the danger was quickly over; and as every boat had contrived to grapple some branch or rock, the voyagers discovered at daybreak that, whatever injuries these had sustained, no lives had been lost. The furious gale they had heard in the distance had raised the waters some twelve feet during the night; but the inundation subsided as rapidly as it had risen. Under the shade of wide-branching trees, and closely hugging the shore, the expedition continued its voyage. The neighbouring forests were remarkable for their luxuriant vegetation; troops of apes and squirrels of various species gambolled among the mighty trees, among which rose conspicuous the superb yao, the king of these forests, the trunk of which shoots up, free from knot or bough, to a height of eighty or one hundred feet; and out of which the Laotians hollow their piraguas. In the morning a wild beast now and then came down to the river to drink; and night was rendered hideous by the cries and trumpetings of deer, and tigers, and elephants. * * * * * ~THE KHON CATARACT.~ At length the voyagers came within hearing of the tremendous roar of the Khon cataract. Their boatmen, brisker than on ordinary occasions, hauled or propelled their vessels through a very labyrinth of rocks, submerged trees, and prostrate trunks still clinging to earth by their many roots. They knew that their hard labour was nearly at an end, and that at Khon the expedition would dismiss them, as fresh boats would be required above the cataract. As for their homeward voyage, what was it? To ascend the river had been the work of a week; the swift current would bear them back in less than a day. ~A PLAGUE OF LEECHES.~
