English: Mamvira Cataract, The First or Lowest of Murchison’s Cataracts. "On the first ascent of the Shire our attention was chiefly directed to the river itself. The delight of threading out the meanderings of upwards of 200 miles of a hitherto unexplored river must be felt to be appreciated. All the lower part of the river was found to be at least two fathoms in depth. It became shallower higher up, where many departing and re-entering branches diminished the volume of water, but the absence of sandbanks made it easy of navigation. We had to exercise the greatest care lest anything we did should be misconstrued by the crowds who watched us. After having made, in a straight line, one hundred miles, although the windings of the river had fully doubled the distance, we found further progress with the steamer arrested, in 15E 55' south, by magnificent cataracts, which we called “The Murchison,” after one whose name has already a world-wide fame, and whose generous kindness we can never repay. The native name of that figured in the woodcut is Mamvira. It is that at which the progress of the steamer was first stopped. The angle of descent is much smaller than that of the five cataracts above it; indeed, so small as compared with them, that after they were discovered this was not included in the number." [p. 78]
