The article focuses on the program for the annual meeting of the Phycological Society of America. The meeting will be held at the University of Alberta, Edmonton, Alberta, in Canada, from June 20-24, 1971. The chairmen of the program will be Harold C. Bold and Louis Druehl. All sessions of the program at which contributed papers, lectures and the symposium are presented are scheduled as joint sessions of the Phycological Society of America, the Phycological Section of the Canadian Botanical Association and the Phycological Section of the Botanical Society of America.

Glock, Ringer, and Babbie have argued that people who become involved in church are seeking a comfortable refuge from the deprivations associated with being old, female, unmarried, or having a small income or little education. The present research tests this thesis using data from a province wide sample of adults in Alberta. No support for the thesis is found among any denominational grouping. When the thesis is broken down into its component hypotheses, however, the pattern of relationships that emerges is one that has long been familiar to sociologists. [ABSTRACT FROM AUTHOR]

Nineteen shales from the continental Belly River Formation and sixteen shales from the marine Wapiabi Formation were studied by X-ray diffraction and fluorescence methods. The diffraction data indicate that dolomite and lilite are present in significant amounts only in the Wapiabi. Feldspar and 12 Å and 14 Å clays are more abundant in the continental shales. The marine shales are enriched in K, Ca, Rb and Zr. The continental shales are higher than marine shales in Sr and Mn. The Rb/K is higher in the marine shales, the Sr/Ca is lower than in the continental shales. [ABSTRACT FROM AUTHOR]

The upper Cretaceous Belly River Formation of the southern Foothills of Alberta is a unit 2,000–2,500 ft. thick composed mainly of mudstone interbedded with lenticular, fine- to medium-grained sandstones in units 5–100 ft. thick. Thin intraformational mudstone-pebble conglomerates, nodular limestones, coal seams, bentonites, magnetite-sandstone, and pelecypod beds make up the remaining, minor part of the lithology. The sandstones are composed of about one-half quartz (and quartzite), one-third rock fragments (including chert), and one-fifth feldspars. They are mostly lithic sandstones in the cIassification scheme adopted. The quartz rock fragments and feldspars are separable into compositional and genetic groups. Variatal minerals are carbonates, chlorites, red and brown biotide, and two types of glauconite. The principal accessory minerals are allanite, apatite, collophane, almandine garnet, tourmaline, and zircon. Albitization of intermediate plagioclase suggest the grade of diagenetic aIteration has neared the laumontite-albite stage. Quantitative clay analysis of nine mudstones, shales and bentonites shows illite and montmorillionite to be the dominant minerals (with considerable mixed layering). Illite is detrital, montmorillonite and mixed-layer clays are diagenetic.
