We passed safely through the rocks and shoals near Walrus Island into an expanse of calm water, sheltered by jutting cliffs, where the sea glanced like a mirror, and for the first time we observed the fairy-like shells of the paper-nautilus sailing lightly over the dazzling surface.

It was impossible to see these lovely seafarers without wishing to obtain specimens; and the canoe accordingly gave chase, presently securing half a dozen, which were handed to us in the yacht to be carefully preserved for the museum, and the place was ever after called Nautilus Creek.

Further on we rounded a short promontory, flat, with an abrupt rock at the extremity, to which we gave the name of Cape Pug-Nose; and then, at some distance, appeared the grand cliffs of a headland running far out to sea.

This I supposed we should have to weather, but my pilots made no change in our course, and, following the canoe, we soon came in sight of the majestic archway which offered us a short passage to Pearl Bay.

The wonderfully architectural appearance of the pillars, arches and pinnacles, surrounding and surmounting this noble entrance, struck me with admiration, resembling parts of a fine gothic cathedral, and inducing me to propose for it the name Cape Minster.

A perfect cloud of little swallows darted from the cavernous entrance on our approach, divided into flocks, soared, wheeled, flew right and left, and finally returned in a body as swiftly as they came, to the sides of the long dark tunnel, which were festooned with their nests.

We detached a number of these as we passed, taking care to leave those containing eggs or young. The best were at a considerable height, but the broken and shelving rocks afforded, in some places, footing for such daring and active climbers as Fritz and Jack, and they quickly obtained as many as we could possibly require.

Our progress was much assisted by the tide, which, like a current, bore us onward along the nave of this natural cathedral; aisles, transepts, screens and side-chapels appearing between the columns and arches which in the `dim religious light' were revealed to our wondering eyes.

On emerging into the dazzling sunshine, we found ourselves floating in the calm expanse of Pearl Bay; but it was some minutes before we could look around on the bright and lovely scene.

Fritz had not overrated its beauty, and the romantic islets which studded its waters seemed to give the effect of a pleasant smile to features already perfect.
