All those summer days, while the Professor was sending cheerful accounts of his activities to his family in France, he was really doing very little. He had begun, in a desultory way, to annotate the diary that Tom had kept on the mesa, in which he had noted down the details of each day’s work among the ruins, along with the weather and anything unusual in the routine of their life.
