I felt my face burn. "But I didn't know anything about it," I said.
"No, but you said that you knew all about it,—and then made the statement."
"I wasn't fair," I admitted. "I hadn't any right to say it; for I didn't know."
"Neither does any one else who makes the same statement," said Uncle Rob. "Now I want to ask you some questions about these earth-works."
"Don't know any more about those than I did about Christian Science."
Uncle Rob laughed. "Haven't you ever paced these squares off and studied the proportions of them and wondered what sort of instruments were used?"
"No," I said, "I haven't."
"And you are planning to be a civil engineer, and have taken no concern in this work, done with such accuracy, hundreds and hundreds of years ago?"
I looked around at the upper square, with a new interest. "Well," I said, "I'm so used to seeing them, you know, that I've never thought much about them,—never thought of them in that way,'t all."
