This writing is the outgrowth of an attempt to produce a correct map of the western New York moraines. The map in later use, figure 2, is fanciful in its exaggeration. This new map, figure 1, is not beautiful, but truthful. It tells nothing but the truth, but fails of necessity to tell all of the facts relating to terminal drift.

But the innumerable lines of the ice-front positions have little scientific importance, although of possible local interest. The more massive and continuous morainic belts are of geologic value, . . .
