This photograph is part of a series taken by the firm of Shepherd and Robertson for a book entitled 'The People of India' by Forbes Watson, published in 1868. The Bheesties are water sellers, and according to Watson the ones seen here are Muslim. Many of them served with the army and were highly regarded for their bravery in battle. 'They go into action with their corps, supplying water under the hottest fire. Many a wounded or dying soldier has been relieved in his agony of thirst by these gallant fellows'.
