Bob took the paper Harvey extended to him. He found it to be a list,
including hundreds of items. The first few lines were like this:

Sec. 4 T, 6 N.R., 26 W S.W. 1/4 of N.W. 1/4
4 6 26 N.W. 1/4 of N.W. 1/4
4 6 26 S.W. 1/4 of S.W. 1/4
5 6 26 S.W. 1/4 of N.W. 1/4
5 6 26 S.E. 1/4 of N.W. 1/4

After an interminable sequence, another of the figures would change, or
a single letter of the alphabet would shift. And so on, column after
column. Bob had not the remotest notion of what it all meant, but he
copied it and handed the result to Harvey. In a few moments Harvey

returned the list to Harvey. Harvey looked sourly at the ink marks, and
gave the boy another list to copy.

Bob found this task, which lasted until noon, fully as exhilarating as
