The cliff they had just ascended evidently extended entirely around the shoreline of the key. Before them the ground sloped into a natural, bowl-like depression. This valley ran the length and breadth of the island, which was about five miles long by two miles wide. The road, gleaming white in the morning sun, ran straight down the valley, to a group of low white buildings, a mile or so away. A heavy growth of trees and shrubs covered the valley. There seemed to have been no attempt to cultivate the soil, and except for the road, the group of buildings and a large house that perched on a knoll in mid-valley, nature had been allowed to run its own pace.
