Natural history. 483 A. M. VerrillâThe Hermxida Islands. 71 differing in fineness and in the amount of small shells and shell-sand. It was not very profitable dredging^ but the siftings yielded many small undescribed shells, annelids, etc. On such white bottoms a very large black Holothurian (Stichopus) is very abundant. It becomes 15 to 18 inches long, and three or four broad. Associated with it are numerous large, nearly black or dark purple sea urchins (Toxopneustes). Both are conspicuous with a water-glass, on account of their dark colors. (See Part V.) The bottoms of chalky mud make excellent anchorages, for it is said that vessels never drag their anchors in it, owing to its tenacity. It is related that a British sloop-of-war, the " Driver," once lost her bowsprit, while weathering a northerly gale in Murray Anchorage, by plunging it so deeply under water that she fouled it under her anchor cable, but yet did not drag the anchor. 12.âThe Beefs or " Flats'%â North Bocks. The outer reefs form an almost continuous semioval boundary wall to the region of lagoons, for over 30 miles, from east of St. George's Island all around to and beyond the western end of the group. They are from half a mile to two miles or more in breadth and in most places are only slightly covered by water at low tide, so that the seas break heavily upon them, in long lines of white breakers in. Figure 27.âThe Eeefs or Flats near North Rock. J. B. Heyl. Phot. December, 1875, by windy weather. In many places, as in the vicinity of the North Rocks, quite extensive areas of the flat reefs are laid bare by low tides. In other large areas the reefs are covered by from 1 foot to 8 feet of water at low tide. These reefs are very irregular in Please note th
