We attempted to grope our way to the bottom, but, not having a light, were soon obliged to give up its further examination.
The island is connected to the cape by a narrow ridge of rocks which the spring-tides may probably cover.

The main corresponds with the island in character and general conformation, being extremely barren and rocky, and of the same description of sandstone, the strata of which appear nearly horizontal; the greatest deviation from that position not being more than an inclination of 5 degrees to the south-east.
Upon our return we landed at Caper Point near the bottom of the bay; where, on taking some bearings, a considerable local magnetic attraction was detected, for the needle of the theodolite was nearly eight degrees in error.

Whilst I was thus employed Mr.Cunningham, who was my companion upon this excursion, ranged about among the shrubs in the vicinity and was fortunate in finding the fruit of a tree that was first seen by us at Cambridge Gulf, and had for some time puzzled us from its immense size and peculiar appearance.

It proved to be a tree of the natural order Capparides, and was thought to be a capparis; the gouty habit of the stem, which was soft and spongy, gave it an appearance of disease: but as all the specimens, from the youngest plant to the full-grown tree, possessed the same deformed appearance, it was evidently the peculiarity of its habit.

The stem of the largest of these trees measured twenty-nine feet in girth whilst its height did not exceed twenty-five feet.
