engineering drawing: Agricultural Chemical Works for Patent Super-Phosphate of Lime with John M. Gallager's Patent Retorts, 1861. T. P. Pemberton, ink with watercolour on paper. Gift of Margaret E. McKenna, 1977 (1977.90). Drawing for the ‘Agricultural Chemical Works’ on Chemical Road. Drawing probably done for the Hopewell Chemical Manufacturing Company that lasted until the early 1860s. It is possible this building was never constructed.
