Pen and ink drawing by Sir Henry Yule (1820-1889) of the site of the bridge over the Hurro River on the Peshawar Road in the North West Frontier Province in Pakistan, dated 1860. The image is inscribed on the front in ink; 'Site of bridge on Hurro River.' Sir Henry served with the Bengal Engineers in India from 1840 to 1862. From 1845 he worked in the North West Provinces (now Uttar Pradesh), with a group of brilliant young engineers, restoring and developing the old Mughal irrigation system. Work on this project was interrupted by the First and Second Sikh Wars (1845-6 and 1848-9) in which Sir Henry participated. At the time this drawing was taken he was Secretary of the Public Works Department for the Government of India, and was largely concerned with irrigation works, roads and railways. He is perhaps best known for his work on the 'Hobson-Jobson' (London, 1886), a glossary of Anglo-Indian colloquial words and phrases.
