As he approached his windows to ascertain what kind of weather was to be found outside, he became aware of sounds which would indicate that some event of activity and hilarity was going on below. He realized now that he had been hearing these sounds--quite without hearing them, after the fashion of the absorbed workman--for the last half-hour. Looking out, he beheld an interesting affair in full swing. At each end of the side yard the heavy snow which a late March storm had brought overnight had been shovelled and manipulated into the semblance of a fort such as lads are wont to make. Between these two entrenchments a battle was raging. But it was no lads who held the places of the combatants. Instead, as he looked, Mr. Jefferson saw rising warily from behind the fort nearest him, a girlish figure in a scarlet blanket suit, its dark head half shielded by a scarlet toboggan cap very much awry. A mittened hand flung a snowball with strength and precision straight into the opposite fort, and the assailant immediately dodged down behind the embankment. From the opposing stronghold then cautiously appeared a head snugly bound in a blue scarf, from which locks of fair hair escaped at divers points. A second snowball, accompanied by a loose flutter of snow, wended its way uncertainly through the air, and fell a foot short of the fort behind which crouched the scarlet figure. The figure immediately rose and fired an answering volley. Peals of laughter and gay shouts rang through the air. At this very moment a third person ran into the yard from the street, calling: "For shame, George! I'm going to take sides with the enemy, and we'll have you out in no time!" Jefferson saw this third figure, in sweater and cap, dash across the open, narrowly escaping a vigorous shower of missiles from the near fort, and disappear behind the farther one. The battle was now on in earnest. Let Scarlet Toboggan fire as fast and as furiously as she might, a merciless bombardment of her protecting walls had begun. The girl in the blue scarf--and priceless furs--had sunk laughing upon the floor of her refuge, while her new ally, bringing to bear the full strength and skill of his sex, battered at the entrenchments across the yard, and began to make havoc thereon. Georgiana was a brave foe, but though she fought with surprising endurance she was beginning to be seriously worsted, several feet of her snow rampart having been shot away, when a voice behind her cried out a command, and an arm, more sinewy than hers, sent a hard shot whizzing past her head into the opposite fort with that directness of aim and effectiveness of delivery which only the male arm can accomplish. "Duck down and make snowballs while I fire!" the voice ordered, and Georgiana, breathless but still undaunted, obeyed.
