and more rational modes of discussion, based upon the central underlying principle of the relations of quantities. Arithmetic is but the science of the relation of quantities as expressed by number. To know, for instance, that 3 apples and 4 apples equal 7 apples is to know that 7 apples less 4 apples equals 3 apples; and to know that A's money equals 1 of B’s money is to know that other relation that B’s money equals twice as much as A's; and further to know that C's equals of D's is to know that D's equals of C's. This, it is believed, will be found to be the distinguishing feature of the work, and upon this feature its claim for indorsement is submitted. It is the outgrowth of years of study and trial in the class-room, -the crucial test of every work of this kind, — and is sent forth to seek favor in other class-rooms. SECOND GRADE. LESSON 1. 1.
