Lantern slide. Showing the Esna barrage. This photograph was taken by Sgt. Johnson of the 436 Welsh Field Company c. 1917. It formed part of a lecture which he gave. The notes from his lecture read 'Another view of the barrage taken from the boat just after passing through the lock' The 'Esna barrage' built 1906-1908 is near Edfu. This view is similar to EC1790.
