The correspondence from D.W. [David William] Smith to President Peter Russell regarding Smith’s desire to sell a certain piece of property in Newark (now Niagara-on-the-Lake, Ont.) to be used as a location for a common grammar school. The notice gives a description of the building situated on the property as being adaptable for the use of a school. The Board of Survey convened in December 1798 to examine Smith’s property and gave an appropriate valuation of the properties and buildings Smith was offering for sale. Smith was the deputy surveyor general of lands for Upper Canada.

Joseph William Winthrop Spencer (commonly known as J.W. Spencer) was a geologist and geomorphologist best known for his work on the geology of southern Ontario and the Great Lakes. He was born in Dundas, Upper Canada in 1851, but moved to Hamilton, Ontario in 1867. In 1871, he began studies in geology at McGill College in Montreal. In 1875 he worked in the Michigan copper mines and shortly afterwards prepared a thesis on the copper deposits. He submitted this thesis to the University of Gottingen in Germany in 1877 and was awarded a doctorate in geology, the second Canadian to earn a doctorate in this field. In 1880, he became a professor of geology and chemistry at King’s College in Windsor, N.S. Subsequently, he taught at the University of Missouri, and then the University of Georgia, but moved to Washington, D.C. in 1894, where he worked as a consultant geologist. Spencer spent much of his life studying preglacial river valleys in Ontario and the origins of the Great Lakes, as well as the Niagara River and Falls. In 1907, he published a book titled The Falls of Niagara: their evolution and varying relations to the Great Lakes. His opinions in these areas differed from some of his contemporaries, namely the American geologist Grove Karl Gilbert. Gilbert published a review of the The Falls of Niagara that exposed some flaws and inaccuracies in Spencer’s estimate of the age of the falls. Spencer’s studies also took him to the Caribbean and Central America. In 1920 he moved back to Canada, but died the following year.

Eight lithologic facies recognized in the Mississippi Fan sediments drilled during DSDP Leg 96 are defined on the basis of lithology, sedimentary structures, composition, and texture. Of these, the calcareous biogenic sediments are of minor importance, volumetrically, as compared with the dominant resedimented terrigenous facies. Clay, mud, and silt are the most abundant sediments at all the sites drilled, with some sand and gravel in the midfan channel fill and an abundance of sand on the lower fan. Facies distribution and vertical sequences reflect the importance of sediment type and supply in controlling fan development. Sea-level changes and diapiric activity have also played an important role. Clay and sand fraction mineralogy closely mirror the dominant sediment source, namely, the Mississippi River system and adjacent continental shelf. Local and regional variation in composition on the fan mostly reflects facies differences.
