Donald Clark glanced up from his Latin grammar and watched his father as he tore open the envelope of a telegram and ran his eye over its contents. Evidently the message was puzzling. Again Mr. Clark read it. Donald wondered what it could be. All the afternoon the yellow envelope had been on the table, and more than once his mind had wandered from the lessons he was preparing to speculate on the possible tidings wrapped up in that sealed packet. Not that a telegram was an unheard-of event in the family. No, his father received many; most of them, however, went to the Boston office, and the boy could not imagine what this one was doing at their Cambridge home.
