(A marvel of Victorian engineering, the Suez Canal opened in 1869 and affected both trade patterns and politics, with the resultant ease of access for Europeans to parts of Africa enabling a new wave of colonization efforts during the 1880s.

The description is identical across three editions of the same manual:
Long flowing robe of cloth-of-gold, with waves of blue satin bordered with pearls, underskirt of red satin embroidered in Egyptian designs. A gold key at the girdle; Egyptian head-dress of pearls, turquoise, and diamonds; girdle of roses and lilies.
