Palaeopigment accumulation and implcations for paleolimnology over the lost century for two Ontario lakes

Crawford Lake is a meromictic lake, which is 24 m deep and has an area of 2.5 ha, and has never been reported to have mixed below 16 m. Lady Evelyn Lake, which became a reservoir when a dam was built in 1916, is dimictic with a maximum depth of about 35 m. 1 My research proved that both native chlorophylls and the ratio of chlorophyll derivatives to total carotenoids were better preserved in the shallower lake (Crawford Lake) because it was meromictic. Thus the anaerobic conditions in Crawford Lake below 16 m (monimolimnion) provide excellent conditions for pigment preservation. Under such conditions, the preservation of both chlorophylls and carotenoids, including oscillaxanthin and myxoxanthophyll, are extremely good compared with those of Lady Evelyn Reservoir, in which anaerobic conditions are rarely encountered at the mud-water interface. During the period from 1500 to 1900 A. D. in Crawford Lake, the accumulation rates of oscillaxanthin and myxoxanthophyll were extremely high, but those of chlorophyll derivatives and total carotenoids were relatively low. This was correlated with the presence of a dense benthic mat of cyanobacteria near the lake's chemocline. Competition for light between the deep dwelling cyanobacteria and overlying phytoplankton in this meromictic lake would have been intensified as the lake became more and more eutrophic (1955-1991 A. D.). During the period from 1955 to 1991 A. D., the accumulation rates of chlorophyll derivatives and total carotenoids in the sediment core from Crawford Lake (0-7.5 cm, 1955-present) increased. During this same period, the accumulation rates of cyanobacterial pigments (Le. oscillaxanthin and myxoxanthophyll) declined as the lake became more eutrophic. Because the major cyanobacteria in Crawford Lake are benthic mat forming Lyngbya and Oscillatoria and not phytoplankton, eutrophication resulted in a decline of the mat forming algal pigments. This is important because in previous palaeolimnological studies the concentrations of oscillaxanthin and myxoxanthophyll have been used as correlates with lake trophic levels. The results of organic carbon a13c analysis on the Crawford Lake sediment core supported the conclusions from the pigment study as noted above. High values of a13c at the depth of 34-48 cm (1500-1760 A. D.) were related to a dense population of benthic Oscillatoria and Lyngbya living on the bottom of the lake during that period. The Oscillatoria and Lyngbya utilized the bicarbonate, which had a high a 13C value. Very low values were found at 0-7 cm in the Crawford sediment core. At this time phytoplankton was the main primary producer, which enriched 12C by photosynthetic assimilation.

Grand Trunk Railway way bills, 1900

The Grand Trunk Railway initially ran from Montreal to Toronto, then with expansion of Canada operated to British Columbia, linking major cities together. In 1900, two way bill forms were completed; one for the Niagara Falls Wine Co. and the other for T.G. Bright & Co. Both companies were headquartered in Niagara Falls, Ont. The consignors were John Mayberry & Co. and John Eleareys?.

Upper Lakes Shipping Ltd. fonds 1955-1990, n.d. (non-inclusive)

In March 1931, Captain Bruce Angus was sent to Sarnia by Gordon C. Leitch, general manager of Toronto Elevators. He was sent to inspect the Sarnian to ensure it was still seaworthy. Leitch was a savvy business man, who had been active in the business community for a number of years. Leitch began his career with a partner in the lumber business. When that went under he moved into graineries and worked for the Winnipeg Wheat Pool for 12 years. After Winnipeg he moved to Toronto, which was closer to his home town of Ridgetown, Ontario. In Toronto Leitch became manager of the Toronto branch of the Canadian Wheat Pool. While managing the wheat pools in Toronto Leitch became aware of huge costs associated with shipping the grains from the praries into the Toronto area. He felt that there was no need for such costs and decided to do something to make them better and cheaper for the business. Originally the grain was loaded onto Lakers that would bring the grain from the praries to Lake Huron and Georgian Bay. It was stored there until needed by the Toronto graineries and then hauled across land by either truck or train. The land journey was the most expensive and the one which Leitch wanted to eliminate. This was a fine plan except for 2 obstacles that were quickly overcome. First of all the Welland canals were not large enough to accommodate the large carriers that were bringing in the grain. This was changing as the expansion and widening of the canals was already underway. The second issue was the lack of storage in Toronto for the grain. The grain elevators had been destroyed by fire in the late 1880s and never replaced. Leitch propsed his company built its own storage elevators along the water front to allow not only for easier access to the grain, and more timely production of products. The elevators would aslo create a reduction in shipping costs and an overall more competitoive price for the customers of the grainery. The company refused, so Leitch went elsewhere to friends and contacts within the grain industry. The elevators were built and Leitch quit his job with the Canadian Wheat Pool and became the general manager of the elevators. Although the elevators were built and ready for storage the next issue was filling them. None of the carriers wanted to do business with Leitch because the competition in Georgian Bay threatened to cancel their contracts if they did. Leitch saw no way around this, but to provide his own transportation. This is when he sent Captain Bruce Angus to scout out potential ships. The ship was purchased for $37,000 and after another $30,000 was spent to fix it up, it was ready for business. The need for transportation and the finding of a seaworthy ship, lead to the beginnings of the Northland Steamship Company. The Sarnian proved to not be enough for the business underway. Leitch decided another ship was necessary. He joined forces with James Norris the owner of the Norris Grain Company. He proposed they join forces to create a more economical means of transportating their products.

E.O. Graham, nurseryman, planting guide leaflets collection, ca. 1900.

Edward Oliver Graham of Rochester, N.Y. worked as a nurseryman in that city for 27 years. He owned a nursery business that operated under his own name for many years. The central office was located in Rochester, but there was also a branch located in Toronto, Ont. In 1903 he formed a company known as the Graham Nursery Company. He died in September 1909.

Office of the University President Sous fonds: Dr. James A. Gibson

Dr. James A. Gibson was born in Ottawa on January 29, 1912 to John W. and Belle Gibson. At an early age the family moved to Victoria, B.C. where John W. Gibson was a director of the Elementary Agricultural Education Branch, Department of Education. Gibson received his early education in Victoria, receiving a B.A. (honours) at UBC in 1931. In 1931 he was awarded the Rhodes scholarship and received his B.A., M.A., B.Litt and D. Phil at New College, Oxford. This was to be the beginning of a long and dedicated relationship with the Rhodes Scholar Association. Upon his return to Canada, Dr. Gibson lectured in Economics and Government at the University of British Columbia. In 1938 he was married to Caroline Stein in Philadelphia, and the same year joined the staff of the Department of External Affairs as a Foreign Service officer. Within twenty minutes of his arrival he was seconded to the Office of the Prime Minister and Secretary of State for External Affairs, W. L. Mackenzie King in charge of War Records and Liaison Officer. This was a critical time in the history of Canada, and Dr. Gibson experienced firsthand several milestones, including the Royal Visit of King George VI and Queen Elizabeth in 1939. Dr. Gibson was present at the formation of the United Nations in San Francisco in 1945, being part of the Prime Minister’s professional staff as well as attending conferences in Washington, Quebec and London as an advisor to the Canadian delegation. Gibson contributed many articles to the publication bout de papier about his experiences during these years. After his resignation in 1947, Gibson joined the staff of the fledgling Carleton College, as a lecturer. In 1949 he was appointed a professor and in 1951 became Dean of Arts and Sciences. Dr. Gibson acted as President from 1955 to 1956 upon the sudden death of Dr. MacOdrum. In 1963 Dr. Gibson accepted the invitation of the Brock University Founders’ Committee, chaired by Arthur Schmon, to become the founding president. Dr. Gibson guided the new University from a converted refrigeration plant, to an ever expanding University campus on the brow of the Niagara Escarpment. Dr. Gibson remained firmly “attached” to Brock University. Even after official retirement, in 1974, he retained the title President Emeritus. Gibson’s final official contribution was an unpublished ten year history of the University. In retirement Gibson remained active in scholarly pursuits. He was a visiting scholar at the Center of Canadian Studies, University of Edinburgh; continued his ongoing research activities focusing on W. L. Mackenzie King, the Office of the Governor General of Canada, and political prisoners transported to Van Dieman’s Land. He remained active in the Canadian Association of Rhodes Scholars, becoming editor from 1975 to 1994 and was appointed Editor Emeritus and Director for Life in 1995 in honour of his dedicated and outstanding service. In 1993 he was awarded one of Canada’s highest achievements, the Order of Canada. Gibson retained close ties with Brock University and many of its faculty. He maintained an office in the Politics Department where he became a vital part of the department. In 1996 Brock University honoured Gibson by naming the University Library in his honour. James A. Gibson Library staff was instrumental in celebrating the 90th birthday of Gibson in 2002, with a widely attended party in the Pond Inlet where many former students, including Silver Badgers. The attendees also included former and current colleagues from Brock University, Canadian Rhodes Scholars Association, family and friends. Gibson was later to remark that the highlight of this event was the gift of his original academic robe which he had personally designed in 1964. In 2003 Dr. Gibson moved to Ottawa to be near some of his children and the city of his birth and early career. In that year “two visits to Brock ensued: the first, to attend a special celebration of the James A. Gibson Library; his late to attend the 74th Convocation on Saturday, October 18, 2003. A week later, in Ottawa, he went for a long walk, returned to his residence, Rideau Gardens, went into the lounge area, took off his coat and folded it up, put it on the back of his chair, sat down, folded his hands in his lap, closed his eyes, and died”.
