A U.S. Navy cruiser's crew and shipyard workers pose on scaffolding built around her twin propellers during a dry-dock period, likely in the late 1890s or early 1900s. Such periodic dockings were essential for scraping marine fouling from the hull and inspecting underwater fittings, and the ship's small-caliber saluting or rapid-fire gun is visible mounted on the quarterdeck rail above.
