diagramming

In diagramming anything Flint could come to be certain that he had been a slow one.

The task of diagramming a territory for invasion is one after Henry H. Rogers' own heart.

A little diagramming will prove that the U-boat must be almost directly in line of its hoped-for victim if it is to score a hit.

He got out of real work by inventing useless activities for his pupils, such as the "tree-diagramming system."
