The foundations for numerous dams in proglacial and interglacial valleys in the Prairie provinces consist of soft alluvial soils. The deposits are up to 60 m deep, and contain thick layers of clay interspersed with lenses and layers of silt, sand, and gravel.This paper describes the damsite investigation and laboratory testing required, the design methods and construction procedures used, and the foundation performance observed during and after construction. A number of empirical relationships between index tests and physical properties of the soils, which provide useful guidelines for preliminary design, are presented.The design approach has gradually evolved from an empirical design with limited testing to a more rational design based on detailed investigations and thorough instrumentation. Increased reliance is placed on observational apparatus to monitor movements and pore pressures to confirm design assumptions as construction proceeds. The theoretical design is always checked with former designs of dams that have performed satisfactorily.Safe economical dams have been constructed in spite of large deformations and high pore pressures. Two case histories illustrate the wide range in dam design for alluvial foundations. The first shows an older design cross section with modifications required to ensure a stable dam, and the second describes a recently constructed dam that incorporates many of the latest design concepts.

Queer moments abound in traditional rituals associated with marriages and weddings, not only in some regions of English Canada but in most European and European-colonised locations. In the Prairie provinces and Ontario, mock weddings (folk dramatic travesties of the Christian/majoritarian wedding ceremony, usually performed cross dressed) can interrupt wedding showers or milestone anniversary parties. And from Prince Edward Island to British Columbia, charivaris (late night visits to a newly married couple, featuring extreme noisemaking and/or traditional trickery) can follow a marriage. The authors question whether these practices transgress against conventional heterosexual marriage or merely ritualise and thus contain potential resistance to its strictures, and find that they do both.

AbstractTetranychus sinhai Baker (Acarina, Tetranychidae), a new pest was observed to infest barley, wheat, and rye crops in the Prairie Provinces of Canada. In barley, typical symptoms of the mite attack are manifested by a darkening of leaves, followed by yellowing and wilting from the bend of the leaf to its tip. The increase in number of mites per leaf was reflected by the showing of advanced symptoms on leaves. One hundred and sixty-five barley varieties from different parts of the world were examined for their reaction to T. sinhai infestation in the field. Of these 15 were found to be resistant, 47 moderately resistant, 88 moderately susceptible, and 15 susceptible. In general, the barley varieties grown in arid regions of the world appeared to be more resistant to T. sinhai infestation.The most commonly grown barley varieties in Canada, Parkland, and Montcalm, were moderately susceptible. Only two North American varieties, Canadian Lake Shore–C.I. 2750, and Gem C.I. 7243 showed high resistance to T. sinhai infestation.
