The firm also engineered the water supplies of the suburbs of Calcutta, and of a large number of Indian towns, including Allahabad, Benares, Cawnpore, Lucknow, Agra, and Srinagar (Kashmir).

Pyne, on behalf of Martin's firm, built for the Emir an arsenal, a mint, and various factories and workshops, subsequently introducing, as state monopolies, a number of modern industries.
