When the mainland streams pour out their floods and the commingled volume hurries north in a mud-tinted, sharply delimited current, and whole trees are cast up on the beaches of far-away isles, vivid examples of the dispersion of animate and inanimate things by purely natural means are afforded. Weighty stones are found locked among roots which, as the wood decays, are deposited on alien sands, thereafter to invite speculation as to origin and means of transport. On one such raft voyaged a living specimen of the white and black banded snake, one of the most singular of the family, for Nature has bestowed on it a placid disposition, and provided it with an unmischievous mouth and fangs so minute that, although classed as venomous, it is not considered injurious to man. Though strange and interesting, on the plea that the family is quite sufficiently represented, the derelict was unwelcome, save as a living proof of the practicability of natural transports. By what grace, indeed, could the creature which earned the Almighty's bitter curse be accepted as “wilsam”--goods of God's mercy driven ashore, no wreck or ship being visible? This small bay never ceases the laying of tribute at one's feet. There are seasons when the amount is less than at others; but how seldom are its sands trodden without a display of the infinite variety of productions of the ocean? When the mood of the sea is savage and the spoil from the reef is flung in ridges among the vegetation of the shore--coral in blocks and shattered masses, shells, seaweed, sponges, and other dead marine animals and driftwood, heap on heap--days of enthusiastic toil might be spent in sorting out the oversurplus of the secrets of the sea. But for months together the beach maintains its cleanly orderliness, and during these dreamy days the sea will tell of many a pretty treasure which the sands will reveal in the face of the sun. The most famous of botanists compiled a floral almanac; the months, and in some cases the weeks, being associated with the development and flowering of significant plants. So might it be possible to ascribe to particular months the tokens with which the obliging sea bestrews the beaches. It is not proposed herein to attempt any such design, which would involve special knowledge of the science of conchology and the compilation of the records of years of patient observation. A few examples of the material on which the delightful work might be undertaken are given, so that the wealth of one brief strip of beach may be taken as typical of a vast stretch of calm waters within the Great Barrier Reef.
