In 1854, Benjamin Shantz acquired a sawmill on Mill Creek from George Butchart, built a gristmill nearby and a community people developed around these mills. Stores, hotels and tanneries were built and a village plot for Port Elgin was laid out in 1857. The original economic development of Port Elgin during the 19th century was based on its harbour facilities on Lake Huron making the village a distribution centre for the surrounding agricultural region. The book includes pictures taken in Hepworth which is located at the base of the Bruce Peninsula on Highway 6 east of Sauble Beach. Sauble Beach is a resort community on the eastern shore of Lake Huron with a beach that is seven miles long; a few pictures taken here are shown. Pictures taken in Shallow Lake, another town located on Highway 6 south and east of Hepworth, have been added. Architectural styles and terms are described in the appendix.
This volume contains the contributions from the speakers at the NATO Advanced Research Workshop on "Structure of the Photosynthetic Bacterial Reaction Center X-ray Crystallography and Optical Spectroscopy with Polarized Light" which was held at the "Maison d'Hotes" of the Centre d'Etudes Nucleaires de Cadarache in the South of France, 20-25 September, 1987. This meeting continued in the spirit of a previous workshop which took place in Feldafing (FRG), March 1985. Photosynthetic reaction centers are intrinsic membrane proteins which, by performing a photoinduced transmembrane charge separation, are responsible for the conversion and storage of solar energy. Since the pioneering work of Reed and Clayton (1968) on the isolation of the reaction center from photosynthetic bacteria, optical spectroscopy with polarized light has been one of the main tools used to investigate the geometrical arrangement of the various chromophores in these systems. The recent elucidation by X-ray crystallography of the structure of several bacterial reaction centers, a breakthrough initiated by Michel and Deisenhofer, has provided us with the atomic coordinates of the pigments and some details about their interactions with neighboring aminoacid residues. This essential step has given a large impetus both to experimentalists and to theoreticians who are now attempting to relate the X-ray structural model to the optical properties of the reaction center and ultimately to its primary biological function.
Erin, Ontario is the subject of Book 22 in the Cruising Ontario series of books of photographs of towns and cities in Ontario. The photos show the architecture and design of old buildings, many that are over 100 years old, with some descriptions of the buildings and background information, but mostly it is a visual experience to enjoy. A small community began at the headwaters of the Credit and Grand Rivers with the erection of mills in 1829-30. The mills were later rebuilt by Daniel McMillan who is in our extended family tree. As we drive from our home in Dundas to the home of our sons and their families in Orangeville, we pass through Erin, often stopping at the bakeshop, and now occasionally making a stop at the Tim Horton's.
