Fonds consists of original manuscript for the romantic opera, "Conrad, or, The Heir of Holstein," adapted from Matthew Gregory Lewis's One O'Clock. Libretto was composed by W. H. Bellamy and music by William Hutchins Callcott.

The collection consists of documents amassed by Roderick Mackenzie. Among the Masson manuscripts there are other series of letters; as well as journals kept by North-Westers and various business documents. Some of this material exists as originals; others are contemporary copies - the George Keith letters for example are contemporary copies on paper watermarked 1827. The collection also includes some duplicate texts - contemporary copies or later nineteenth-century copies that in some cases represent edited versions of the texts. Samuel Wilcocke's account of the death of Benjamin Frobisher exists in a draft original (or contemporary copy) and in a late nineteenth-century clean copy. Of course Benjamin Frobisher did not die in the dramatic circumstances as recorded by Wilcocke, but peacefully in Quebec City in 1821.

This material consists of business documents and correspondence reflecting the activities of the St. Lawrence Steamboat Co., mostly for the pre-1840 period, although there are documents dating to 1863. The major portion of the fonds, comprising 83 of a total 89 volumes, consist of freight books (1819-1833) and passage books (1822-1838). These logs provide information on passengers and goods carried between Montreal and Quebec, as well as other stops such as Chambly. The fonds includes information on fifteen steamboats and two barges, operated by the St. Lawrence Steamboat Company, which made voyages between 1819 and 1838. The data found in the vessel logs in the fonds include names of vessels, details on their crews, quantities of fuel aboard such as wood and coal, and the number of downbound voyages (that is, from Montreal to Quebec) and upbound voyages per seasons (generally from May through November). Lists of cabin and steerage passengers as well as descriptions and quantities of goods carried between Montreal, Chambly, Sorel, Trois-Rivieres, and Quebec are also sometimes included in the logs. The information also includes charges levied for passage and for freight as well as the names of consignors (shippers of goods) and consignees (receivers of goods, usually a merchant), as well as the destination address. The steamboats found in the fonds also frequently towed barges and brigs, whose names are sometimes recorded along with the charges levied. In addition to these vessel logs, the fonds also includes: account books, 1803-1818, 1844, 1851; wage books, 1826-1832-1835; bills of lading, 1812-1813; and letterbooks, 1827-1829, 1843-1863. One book of account pertains to laundering costs for the years 1819 to 1828; a journal (log book) for the “Lady Sherbrooke” for 1823 is also included. Finally, there is an inventory of furniture, bedding and wares onboard th steamers in 1829, 1831, and 1833, and an unrelated and incomplete pay list for dock workers dated September 1892.

Diaries with gaps for the years 1868 to 1910. Also included are a diary of a trip to Scotland and England in 1862 and a scrapbook which covers the years 1863-1869 as well as a catalogue of Wicksteed's library.
