"Livingstone's memory will always be preserved in connection with the exploration of the Zambesi, and the discovery of the great cataract of Mosi-oa-tunya, better known as the Victoria Falls of the Zambesi, though the former name is to be preferred. "He discovered the falls in 1855, on his first ascent of the valley of the Zambesi, and the account he gave was so startling that he was thought to be wandering from the truth. In his second journey, five years later, he made a detailed examination of the cataract, making careful measurements of the heights and distances, so that there could be no mistake. If you look at his book and compare the measurements with those of Niagara, you can hardly fail to be astonished." Fred went below to find the volume in question, and soon returned with it. From Dr. Livingstone's description of the great Falls of the Zambesi he read the following: "On the 9th of August, 1860, we proceeded to see the Victoria Falls. Mosi-oa-tunya is the native name, and means smoke-sounding. Seongo, or Chongwe, meaning the rainbow, or the place of the rainbow, was the more ancient term they bore. We embarked in canoes belonging to Tuba Mokoro (smasher of canoes)--an ominous name; but he alone, it seems, knew the medicine which insures one against shipwreck in the rapids above the falls. For some miles the river was smooth and tranquil, and we glided pleasantly over water as clear as crystal, and past lovely islands, densely covered with a tropical vegetation. But our attention was quickly called from the charming islands to the dangerous rapids, down which Tuba might unintentionally shoot us. To confess the truth, the very ugly aspect of these roaring rapids could scarcely fail to cause some uneasiness in the minds of new-comers. It is only when the river is very low, as it was now, that any one durst venture to the island to which we were bound. If one went during the period of flood, and fortunately hit the island, he would be compelled to remain there till the water subsided again, if he lived so long. Both hippopotami and elephants have been known to be swept over the falls, and of course smashed to pulp. "After many narrow escapes from being dashed on the rocks we landed at the head of Garden Island, which is situated near the middle of the river, and on the lip of the falls.
