"Lined up along the iron railings that surrounded the small asphalt yard of the school were twenty or so children, one to a gap. They presented a row of pale, solemn faces with great, round eyes, that had watched who knew how much of the mournful proceedings, and their little hands held the railings tight, and they were all of them quite silent, quite motionless. It was an oddly grave and touching sight, they looked so unlike children generally do, animated and carefree." Why does this sight seem so odd to Arthur?
