Since the first offshore Lake Erie well was drilled in 1941, the Grimsby and Thorold formations of the Cataract Group have been economically important to the oil and gas industry of Ontario. The Cataract Group provides a significant amount of Ontario's gas production primarily from wells located on Lake Erie. The Grimsby - Thorold formations are the result of nearshore estuarine processes influenced by tides on a prograding shelf and are composed of subtidal channel complexes, discrete tidal channels, mud flats and non-marine deposits. Deposition was related to a regressive - transgressive cycle associated with eustatic sea level changes caused by the melting and resurgence of continental glaciation centred in Africa in the Late Ordovician/Early Silurian. Grimsby deposition began during a regression with the deposition of subtidal channel complexes incised into the marine deposits of the Cabot Head Formation. The presence of mud drapes and mud couplets suggest that these deposits were influenced by tides. These deposits dominate the lower half of the Grimsby. Deposition continued with a change from these subtidal channel complexes to laterally migrating, discrete, shallow tidal channels and mud flats. These were in turn overlain by the non-marine deposits of the Thorold Formation. Grimsby - Thorold deposition ended with a major transgression replacing siliciclastic deposition with primarily carbonate deposition. Sediment was sourced from the east and southeast and associated with a continuation of the Taconic Orogeny into the Early Silurian. The fluvial head of the estuary prograded from a shoreline that was located in western New York and western Pennsylvania running NNE-SSW and then turning NW-SE and paralleling the present day Lake Erie shoreline. iii The facies attributed to the Grimsby - Thorold formations can be ascribed to the three zones within the tripartite zonation suggested by Dalrymple et ale (1992) for estuaries, that is, a marine-dominated facies, a mixed energy facies, and a facies that is dominated by fluvial processes. Also, sediments within the Grimsby - Thorold are commonly fining upwards sequences which are common in estuarine settings whereas deltaic deposits are normally composed of coarsening upwards sequences in a vertical wedge shape with coarser material near the head. The only coarsening observed was in the Thorold Formation and attributed to non-marine deposition by palynological evidence. The presence of a lag deposit at the base of the sediments of the Grimsby Thorold formations suggests that they were incised into the Cabot Head Formation. Further, the thickness of Early Silurian sediments located between the top of the Queenston Formation, where Early Silurian sedimentation began, to the top of the Reynales - Irondequoit formation are constant whether the Grimsby - Thorold formations are present or not. Also, cross-sections using a sand body located in the Cabot Head Formation for correlation further imply that the Grimsby Formation has been incised into the previous deposits of the Cabot Head.

The lower Silurian Whirlpool Sandstone is composed of two main units: a fluvial unit and an estuarine to transitional marine unit. The lowermost unit is made up of sandy braided fluvial deposits, in shallow valleys, that flowed towards the northwest. The fluvial channels are largely filled by cross-bedded, well sorted, quartzose sands, with little ripple crosslaminated or overbank shales. Erosionally overlying this lower unit are brackish water to marine deposits. In the east, this unit consists of estuarine channels and tidal flat deposits. The channels consist of fluvial sands at the base, changing upwards into brackish and tidally influenced channelized sandstones and shales. The estuarine channels flowed to the southwest. Westwards, the unit contains backbarrier facies with extensive washover deposits. Separating the backbarrier facies from shoreface sandstone facies to the west, are barrier island sands represented by barrier-foreshore facies. The barrier islands are dissected by tidal inlets characterized by fining upward abandonment sequences. Inlet deposits are also present west of the barrier island, abandoned by transgression on the shoreface. The sandy marine deposits are replaced to the west by carbonates of the Manitoulin Limestone. During the latest Ordovician, a hiatus in crustal loading during the Taconic Orogeny led to erosional offloading and crustal rebound, the eroded material distributed towards the west, northwest and north as the terrestrial deposits of the fluvial Whirlpool. The "anti-peripheral bulge" of the rebound interfered with the peripheral bulge of the Michigan Basin, nulling the Algonquin Arch, and allowing the detritus of the fluvial Whirlpool to spread onto the Algonquin Arch. The Taconic Orogeny resumed in the earliest Silurian with crustal loading to the south and southeast, and causing tilting of the surface slope in subsurface Lake Erie towards the ii southwest. Lowstand terrestrial deposits were scoured into the new slope. The new crustal loading also reactivated the peripheral bulge of the Appalachian Basin, allowing it to interact with the bulge of the Michigan Basin, raising the Algonquin Arch. The crustal loading depressed the Appalachian basin and allowed transgression to occur. The renewed Algonquin Arch allowed the early Silurian transgression to proceed up two slopes, one to the east and one to the west. The transgression to the east entered the lowstand valleys and created the estuarine Whirlpool. The rising arch caused progradation of the Manitoulin carbonates upon shoreface facies of the Whirlpool Sandstone and upon offshore facies of the Cabot Head Formation. Further crustal loading caused basin subsidence and rapid transgression, abandoning the Whirlpool estuary in an offshore setting.

Materials related to military and naval operations of the 1812 era, research of the late Robert Malcomson, Canadian author and historian. Materials include photocopies of materials relating to the War of 1812, photographs and detailed research notes Malcomson made regarding his approach to research (mainly found in Series VIII). Materials were originally arranged in binders relating to an area of research or a certain publication. Articles were removed from the binders and placed in folders using original titles from the binders as series or sub-series titles. Articles within the binders were separated by tabs indicating what the article related to in the publication or topic of interest. In order to avoid repetition, the writing on the tab was used for folder titles, as each folder would be a part of the Series under which it was grouped. The tab names could be authors, events, accounts etc. of the War. Series and sub-series titles were derived from the original titles on the binders. Original intellectual order was retained, grouping similar subjects into Series and Sub-series. Dates recorded were the publication dates of the articles; however, if no publication date was present the date of retrieval was used if from an academic database (ex. JSTOR). The black and white photos from various repositories are reproductions of paintings, microfilm etc. on photographic paper. The colour photographs from various repositories are actual photographs. All books donated by Malcomson were integrated into the University’s Special Collections book collection. These volumes are noted at the end of the finding aid under separated materials.

George Henry Cornish (1834-1912) was a Methodist minister whose circuits included Clinton, Ont. (1859), Newcastle, Ont. (1861), and Caledonia/Binbrook/Glanford, Ont. (1864- 1865). He wrote several books on the Methodist Church in Canada, including the Cyclopaedia of Methodism in Canada (1881) and the Handbook of Canadian Methodism (1867).

A woman identified only by the broach at her neck as "Ruth" is pictured here in a black and white cabinet card photograph by G. A. Hemstreet. The photo is undated, but believed to be from the late 1870s or early 1880s. The photographer's name is stamped in black ink along the bottom of the card: "G. A. Hemstreet, Photographer, Milton, Ont." This cabinet card was in the possession of Iris Sloman Bell, of St. Catharines, whose relatives include former Black slaves from the United States.G. A. Hemstreet, also known as George A. Hemstreet, was a photographer in Milton, Ontario from 1877 - 1887. Source: Phillips, Glen C. The Ontario photographers list (1851-1900).
