Henry C. Barkley (c.1825–c.1895) was a civil engineer and author. His travel books included Between the Danube and the Black Sea (1876), which covers the five years in which he was working on the construction of a railway line linking the Danube and the Black Sea, and Bulgaria before the War (1877), written at the time of the Russo-Turkish war. (He also wrote a guide to rat-catching for public-school boys, and My Boyhood (1877), a collection of tales from his own childhood.) Published in 1891, this work recounts the author's adventures on a journey that took him in 1878 from Bucharest, through Istanbul, across Asia Minor and back to Trebizond (now Trabzon) on the Black Sea coast, a distance of 1400 miles, completed in 96 days. He describes with zest and humour the habits and customs of Christian and Muslim communities that he encounters on the way.
