Second Welland Canal - Book 3, Survey Map 8 - Quaker Bridge in Thorold

Survey map of the Second Welland Canal created by the Welland Canal Company showing the canal in the Thorold Township between Port Robinson and Welland. Identified structures and features associated with the Canal include the towing path, back ditch, and the waterway itself. The surveyors' measurements and notes can be seen in red and black ink and pencil. Local area landmarks are also identified and include roads and streets (ex. Road to Port Robinson), Quaker Bridge, Hagar's Wood Wharf, Spoil Bank, and several ponds. Properties and property owners of note are: Lots 222, 223, and 224, Johnathan Hagar, E. Shotwell, and Alem Marr.

Niagara Falls Suspension Bridge Company fonds, 1875-1876, 1878, 1884

In 1846, the governments of Upper Canada and the State of New York initiated the creation of two companies that would be authorized to build a bridge over the Niagara River. The bridge was to be owned by both companies, respectively known as the Niagara Falls Suspension Bridge Company (Canadian) and the International Bridge Company (American). A suspension bridge was completed in 1848. This bridge was later replaced by a second suspension bridge that accommodated railways, built in 1853-54. However, the increasing weight of trains made it necessary for the bridge to be redesigned, and a third bridge was completed in 1886. Eventually, this bridge was replaced by a steel arch bridge, which was completed in 1897.

Niagara Falls Bridge Commission Scrapbooks, 1941-1948, 1953-1963, 1965-1974

The Niagara Falls Bridge Commission was created by a joint resolution of the 1938 U.S. Congressional Third Session. The Extra Provincial Corporations Act of Ontario, Canada licenses the Niagara Falls Bridge Commission. Canada and the United States are equally represented on the Commission by an 8 member Board of Commissioners. Canadian commissioners are appointed by the Premier of Ontario. The three Niagara bridges are the Whirlpool Bridge, the Lewiston-Queenston Bridge and the Rainbow Bridge. Source:http://niagarafallsbridges.com/index.php3

Niagara Suspension Bridge Bank note, 1841

The Niagara Suspension Bridge Bank operated in Queenston in 1840. The bank issued notes in denominations of ten dollars, five dollars and one dollar, and featured a drawing of the Queenston-Lewiston Bridge, ten years prior to its construction. The notes are signed by the bank’s Cashier, Gilbert McMicken, and President, Joseph Hamilton. The bank failed a year after its establishment.

Modeling Metal Protein Complexes from Experimental Extended X-ray Absorption Fine Structure using Computational Intelligence

Experimental Extended X-ray Absorption Fine Structure (EXAFS) spectra carry information about the chemical structure of metal protein complexes. However, pre- dicting the structure of such complexes from EXAFS spectra is not a simple task. Currently methods such as Monte Carlo optimization or simulated annealing are used in structure refinement of EXAFS. These methods have proven somewhat successful in structure refinement but have not been successful in finding the global minima. Multiple population based algorithms, including a genetic algorithm, a restarting ge- netic algorithm, differential evolution, and particle swarm optimization, are studied for their effectiveness in structure refinement of EXAFS. The oxygen-evolving com- plex in S1 is used as a benchmark for comparing the algorithms. These algorithms were successful in finding new atomic structures that produced improved calculated EXAFS spectra over atomic structures previously found.

Henley Bridge blueprints, 1939 [photocopies]

Four pages of photocopied blueprints of the Henley Bridge on the Queen Elizabeth Way in St. Catharines, Ontario. A note below the title indicates the bridge was opened by Her Majesty Queen Elizabeth on June 7, 1939. Three of the pages are part of the same blueprint and can be fit together to recreate the complete blueprint. The remaining page is an incomplete blueprint drawn by William Lyon Somerville, Architect, and dated March 24, 1939.

Intemperance at Meredith Bridge, 1836

A document titled "Plain Facts, In relation to the state of intemperance at Meredith Bridge, ascertained by a committee recently appointed for that purpose". The introduction to the document reads: "The whole population of the village, embracing a tract of territory less than one mile from the Bridge, is nine hundred forty. The number of families within those limits is one hundred and sixty-six. Of the heads of these families, thirty-eight are intemperate, - seventy are temperate drinkers; the remainder abstain wholly from the use of distilled and vinous liquors. There are ninety-six children in those families,in which there is one intemperate parent. The number of children who have temperate parents is one hundred and fifty-nine. The other families have one hundred and forty-four children. Beside the above, there are thirty-seven young men. Of this number, twelve are decidedly intemperate; seventeen are temperate drinkers, and eight subscribe to the doctrine of total abstinate. In the whole Village, there are, at the least, fifty-two decidedly intemperate. There are sold in this Village, annually nine thousand gallons of spirituous liquors, at a cost not less than $6,750. Add to this the other cost attendant on the use of spirituous liquors, estimated to equal that of the liquor itself, and we have an item of expense of $13,500, occasioned by the use of intoxicating drink. The above facts are offered for the serious consideration of the citizens at Meredith Bridge. March 1836".
