No restriction is placed on subject matter and the series reflects the broad interests and policies of Fisheries and Oceans Canada, namely, fisheries and aquatic sciences. Technical reports may be cited as full publications. The correct citation appears above the abstract of each report. Each report is abstracted in the data base Aquatic Sciences and Fisheries Abstracts. Technical reports are produced regionally but are numbered nationally. Requests for individual reports will be filled by the issuing establishment listed on the front cover and title page. Numbers 1-456 in this series were issued as Technical Reports of the Fisheries Research Board of Canada. Numbers 457-714 were issued as Department of the Environment, Fisheries and Marine Service, Research and Development Directorate Technical Reports. Numbers 715-924 were issued as Department of Fisheries and Environment, Fisheries and Marine Service Technical Reports. The current series name was changed with report number 925. Rapport technique canadien des sciences halieutiques et aquatiques Les rapports techniques contiennent des renseignements scientifiques et techniques qui constituent une contribution aux connaissances actuelles, mais qui ne sont pas normalement appropriés pour la publication dans un journal scientifique. Les rapports techniques sont destinés essentiellement à un public international et ils sont distribués à cet échelon. II n'y a aucune restriction quant au sujet; de fait, la série reflète la vaste gamme des intérêts et des politiques de Pêches et Océans Canada, c'est-à-dire les sciences halieutiques et aquatiques. Les rapports techniques peuvent être cités comme des publications à part entière. Le titre exact figure au- dessus du résumé de chaque rapport. Les rapports techniques sont résumés dans la base de données Résumés des sciences aquatiques et halieutiques. Les rapports techniques sont produits à l'échelon régional, mais numérotés à l'échelon national. Les demandes de rapports seront satisfaites par l'établissement auteur dont le nom figure sur la couverture et la page du titre. Les numéros 1 à 456 de cette série ont été publiés à titre de Rapports techniques de l'Office des recherches sur les pêcheries du Canada.

    On the cover The continuous kiln of the Clayburn Brick Works was part of J.B. Millar’s plant expansion in 1911. Such a kiln consists of several inter-connected chambers which allow the heat produced in one section to pass through all of the others before going up the chimney. This chimney, the highest structure in Clayburn, was a landmark visible for many miles until it was pulled down in the 1930s. On its face is written “Clayburn 1911” in raised, buff coloured brick.

  • A Stylistic Analysis of the Petroglyphs of Gabriola
    VISIONS CAST ON STONE: A STYLISTIC ANALYSIS OF THE PETROGLYPHS OF GABRIOLA ISLAND, B.C. By AMANDA SHEA ADAMS BA. University of California, Berkeley, 2001 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS in THE FACULTY OF GRADUATE STUDIES (Department of Anthropology and Sociology) We accept this thesis as conforming to the required'standards. THE UNIVERSITY OF BRITISH COLUMBIA DECEMBER 2003 © AMANDA SHEA ADAMS Library Authorization In presenting this thesis in partial fulfillment of the requirements for an advanced degree at the University of British Columbia, I agree that the Library shall make it freely available for reference and study. I further agree that permission for extensive copying of this thesis for scholarly purposes may be granted by the head of my department or by his or her representatives. It is understood that copying or publication of this thesis for financial gain shall not be allowed without my written permission. Name of Author (please print) Date / • • Title of Thesis: *1//£/CA/£ C/)£7~" &'7~OA*/££-~ S4— Degree: /HA~ Year: sZcTb 3> \ ABSTRACT This study explores the stylistic variability and underlying cohesion of the petroglyphs sites located on Gabriola Island, British Columbia, a southern Gulf Island in the Gulf of Georgia region of the Northwest Coast (North America). I view the petroglyphs as an inter-related body of ancient imagery and deliberately move away from (historical and widespread) attempts at large regional syntheses of 'rock art' and towards a study of smaller and more precise proportion. In this thesis, I propose that the majority of petroglyphs located on Gabriola Island were made in a short period of time, perhaps over the course of a single life (if a single, prolific specialist were responsible for most of the imagery) or, at most, over the course of a few generations (maybe a family of trained carvers).

  • Cortes Island Community Broadband Plan About Cortes Island
    CORTES ISLAND COMMUNITY BROADBAND PLAN ABOUT CORTES ISLAND Cortes Island is approximately 25 km long and 13 km wide, situated at the northern end of the Salish Sea (Strait of Georgia), between Vancouver Island and the British Columbia mainland. Accessible via a 40-minute ferry ride from Quadra Island and a shorter 10 minute ferry crossing from the City of Campbell River. Like many other west coast communities, Cortes Island was inhabited by Indigenous peoples prior to colonization. Coast Salish people made use of Cortes Island for thousands of years, but a smallpox epidemic decimated the population in the late 1700’s. Today, the Klahoose First Nation live at Squirrel Cove. The Indigenous comprise of 7.0% of Cortes Island’s total population.1, 2 The island currently has about 1,035 full-time residents, and most live on the southern portion. The largest age cohort on Cortes Island is 15-64 years old and they comprise 58.9% of the population. The remainder of the population is comprised of seniors (28.0%), children 14 years old and younger (13.1%) and the median age of the population is 53.5 years.1 The population increases in the summer, as Cortes hosts about 3,000 people per day. 3 Cortes Island is a member of the Strathcona Regional District’s Area B. The median value of a home is $300,973 with a $383 median monthly cost of home ownership. Median monthly cost is the total cost for a mortgage, property taxes, and the cost of electricity, heat, water, and other municipal services.
