A dozen boys were playing ball in a field adjoining the boarding-school of Dr. Pericles Benton, in the town of Walltham, a hundred and twenty-five miles northeast of the city of New York. These boys varied in age from thirteen to seventeen. In another part of the field a few younger boys were amusing themselves. All these boys were boarding-scholars connected with the school.
