Birmingham Botanical Gardens may seem an unlikely place to explore the wonders of the Industrial Revolution, but hidden behind its fragrant borders Guy Martin finds a hidden world of hi-tech Victorian engineering, show-off architecture, intrepid plant-hunters scouring the furthest corners of the Empire, and city fathers terrified of the 'degenerate' urban poor.—Enzedder
