An unusual album in which the photographs document the epic nature of the construction work from February 1891 and the completed headworks in March 1892. Including a view with Lord and Lady Lansdowne and dogs on the weir while workers demonstrate the raising of the weir shutters, and a comparison between the up-stream view of the under-sluices with the river at normal level and during the flood of August 1892. The two albumen prints are from negatives made on 16 August showing the River Chenab in flood.
