The ritual of the Church of England is contained in the Book of Common Prayer with its rubrics. The Roman ritual is divided into the breviary, the missal, the ritual, and the pontifical. The ritual contains those offices which may be administered by a priest, while the pontifical deals with those which can only be per- formed by a bishop. Ritualists, a name adopted by those who, at the commencement of the Oxford Move- ment, devoted themselves to the task of pro- curing an exact and intelligent following of the rubrics of the Book of Common Prayer. They were then led to study the whole ritual system of the Catholic Church, and many of them adopted rites and ceremonies for which no direct authority could be found in the Anglican prayer-book, and some of which have been forbidden by decisions of ecclesi- astical courts. In 1874 the General Conven- tion of the Protestant Episcopal Church at- tempted to legislate against alleged ritualistic practices. River, a mass of water moving down a def- inite channel from a higher to a lower ele- vation. The speed of a river increases with its slope and volume.

The Missouri has a comparatively rapid descent for such a large river—about 28 in. per m. (about one in 2,250). Some parts of a river's course are areas of
