The way we captured the two latter was by turning over the rocks, to the under sides of which we found them adhering in great numbers, sticking on like snails to a garden wall.  Some of the cowries were very beautiful, particularly those of a deep brown colour approaching to black.  This kind, however, were rather rare, and the lucky finder of a large one excited some envy.  These beautiful little shells are of all sizes, from half an inch to two inches in length.  When the stone is first turned over, the fish is almost out of its home, and the bright colour of the shell is hidden by a fleshy integument, but a few seconds suffice for it to withdraw within doors, and then the mottled pattern is seen in its full beauty.  The best way to get the shell without injury to its gloss, is to keep the fish alive in a bucket of salt water, until you reach home, and then to dig a hole a couple of feet deep, and bury them.  In a month or so, they may be taken up, and will be found quite clean, free from smell, and as bright in hue as during life.  I have tried boiling them, heaping them in the sun, and various other methods, but this is undoubtedly the best.

Should it ever fall to the lot of any of my readers to have to cook periwinkles —­ and there are many worse things, when you are certain of their freshness —­ let them remember that they should be boiled in ’salt water’.  This is to give them toughness; if fresh water is used, however expert the operator may be with his pin, he will fail to extract more than a moiety of the curly delicacy.  These little facts, though extraneous to our subject, are always worth knowing.

At one end of Garden Island, and distant from it about 200 yards, stands a very singular rock, of a whitish hue, and when struck at a certain angle by the sun, so much resembling the canvas of a vessel, that it was named the “Sail Rock.”  At low tide this could be reached by wading, the water being little more than knee-deep.  Its base was literally covered with oysters of the finest quality.  The mere task of getting there was one of considerable difficulty, for the rock was as slippery as glass, and whenever you got a fall —­ which happened on an average every five minutes —­ bleeding hands and jagged knees bore testimony to a couch of growing bivalves being anything but as soft as a feather bed; also the oysters cling so fast that they might be taken for component parts of the rock, and only a cold chisel and mallet will induce them to relinquish their firm embrace.  Three or four of the party had ventured out, and we had secured a large sackful, after which we all retired to the tent, except one of our number, who, having a lady-love in Cardwell with an inordinate affection for shell-fish, lingered to fill a haversack for his ‘inamorata’.  We were comfortably smoking our pipes and watching with satisfaction the tide rising higher and higher, when a faint “coo-eh” from the direction of the rock reached us, followed by another and another and another, each one more shrill than the last.
