So much then for my first principle: "From the beginning to the end of the course correlate arithmetic with other subjects, and teach in part at least as a means to an end." The second principle was evolved by thinking upon what a lovely subject arithmetic is in one way; just a lovely little series of steps, the first step leading up to the next one, and so on. Well, in making a set of stairs it won't be very much good to have one step there, another there, and another over there; so I took for my second principle what my friend Mr. McMurray calls "Tying your ends;" link vhat you do with what, has gone before.

It is a number--it is a fraction. It is a decimal and there is really not much new to be learned about it except the "five cases" that cover all, of p...
