Description of the island mentioned in Chapter 14.

From the text:

I had crossed a marshy tract full of willows, bulrushes, and odd, outlandish, swampy trees; and I had now come out upon the skirts of an open piece of undulating, sandy country, about a mile long, dotted with a few pines and a great number of contorted trees, not unlike the oak in
growth, but pale in the foliage, like willows. On the far side of the open stood one of the hills, with two quaint, craggy peaks shining vividly in the sun.

Then I came to a long thicket of these oaklike trees—live, or evergreen, oaks, I heard afterwards they should be called—which grew low along the sand like brambles, the boughs curiously twisted, the foliage compact, like thatch. The thicket stretched down from the top of one of the sandy knolls, spreading and growing taller as it went, until it reached the margin of the broad, reedy fen, through which the nearest of the little rivers soaked its way into the anchorage. The marsh was steaming in the strong sun, and the outline of the Spy-glass trembled through the haze.
