In "The Thirteen-Gun Salute" by Patrick O'Brian, the narrator expresses a profound appreciation for a pristine, isolated volcanic island. This island, rich in fertile land and vibrant vegetation, holds immense value for a naturalist. The absence of harmful introduced species like rats and dogs allows it to remain an untouched paradise, showcasing its ecological significance.

The quote highlights the unique allure of such an unspoiled environment for scientific exploration and observation. For naturalists, discovering a location that has not been tainted by human interference is an extraordinary opportunity, emphasizing the importance of protecting these rare ecosystems from destruction.
