Lights appeared at the rear windows of the tenements, and families sat at supper. It was snell weather again, the sky dark with threat of snow, and the windows were all closed. But with a sharp bark beneath the lowest of them Bobby could have made his presence and his wants known. He watched the people eating, sitting wistfully about on his haunches here and there, but remaining silent. By and by there were sounds of crying babies, of crockery being washed, and the ringing of church bells far and near. Then the lights were extinguished, and huge bulks of shadow, of tenements and kirk, engulfed the kirkyard. When Bobby lay down on Auld Jock's grave, pellets of frozen snow were falling and the air had hardened toward frost. VI. Sleep alone goes far to revive a little dog, and fasting sharpens the wits. Bobby was so tired that he slept soundly, but so hungry that he woke early, and instantly alert to his situation. It was so very early of a dark winter morning that not even the sparrows were out foraging in the kirkyard for dry seeds. The drum and bugle had not been sounded from the Castle when the milk and dustman's carts began to clatter over the frozen streets. With the first hint of dawn stout fishwives, who had tramped all the way in from the piers of Newhaven with heavily laden creels on their heads, were lustily crying their “caller herrin'.” Soon fagot men began to call up the courts of tenements, where fuel was bought by the scant bundle: “Are ye cauld?” Many a human waif in the tall buildings about the lower end of Greyfriars kirkyard was cold, even in bed, but, in his thick underjacket of fleece, Bobby was as warm as a plate of breakfast toast. With a vigorous shaking he broke and scattered the crust of snow that burdened his shaggy thatch. Then he lay down on the grave again, with his nose on his paws. Urgent matters occupied the little dog's mind. To deal with these affairs he had the long head of the canniest Scot, wide and high between the ears, and a muzzle as determined as a little steel trap. Small and forlorn as he was, courage, resource and purpose marked him.
