Fonds consists of two hand-sewn booklets, each with five original architectural drawings of the "Hamilton District of Newcastle" gaol and court house. Each sheet has a title depicting the section of the building drawn, i.e., "Ground plan of a court house and gaol to be built at Hamilton district of Newcastle as proposed by Archibald Fraser." All sheets are signed by Archibald Fraser and are undated. Some of the sheets are coloured.

This fonds consists of photocopies of the minutes of the gaol and courthouse building committee, from 1828 to 1831, at Amherst in Hamilton Township, Newcastle District.
