The revised edition of Practical Argumentation is the result of a constant demand on the part of teachers of argumentation and debate for new supplementary material with which to work. The author has endeavored to satisfy this demand by making a complete revision of all class-room exercises and by introducing in nearly every instance fresh material to illustrate the various steps in argumentative composition. A few illustrations that have proved to be of special worth have been retained form the first edition, but all the briefs and most of the extracts from magazine articles and speeches have not appeared before in any text-book. Moreover, as in the first edition, these illustrations have been taken largely from contemporary and popular sources. The models are such that student should have no insuperable difficulty in imitating them; and they have, furthermore, been chosen with the idea of arousing interest. The main body of the book and its fundamental teachings remain practically unchanged.
