To quickly assess the difficulty of the text, read a short excerpt:
The gradient of depth without the reef is exceedingly steep, the dark blue of ocean depths being entered at once upon crossing the barrier. For lack of proper apparatus for obtaining bottom samples from the deeper water without the reef we were unable to determine whether or not a line of dead reef exists on the slope without. From other indications, however, we were of the opinion that the platform (the island shelf) is of fairly recent submergence to about its present depth and that the prese...nt living reef is too young to have ex- panded very far in a seaward direction. The coral polyps find here almost ideal conditions for growth, — shallow water, high temperature, and a steady current, richly laden with food sweeping the edge of the shelf. No rivers with burden of silt interfere and the water is of exceptional purity. Along a rising coast successive lines of fringing reef with occasional inner patches of dying coral might be expected, the outer ones being in the most flourishing condition.
