One night,—a solemn, black, breathless August night, when half-visible heat lightning turned the murk of the western horizon to pulses of dirty sulphur,—Lad awoke from a fitful dream of chasing squirrels which had never learned to climb. He sat up on his rug, blinking around through the gloom in the half hope that some of those non-climbing squirrels might still be in sight. As they were not, he sighed unhappily and prepared to lay his classic young head back again on the rug for another spell of night-shortening sleep. But, before his head could touch the rug, he reared it and half of his small body from the floor and focused his nearsighted eyes on the driveway. At the same time, his tail began to wag a thumping welcome. Now, by day, a dog cannot see so far nor so clearly as can a human. But by night,—for comparatively short distances,—he can see much better than can his master. By day or by darkness, his keen hearing and keener scent make up for all defects of eyesight. And now three of Lad’s senses told him he was no longer alone in his tedious vigil. Down the drive, moving with amusing slowness and silence, a man was coming. He was on foot. And he was fairly well dressed. Dogs,—the foremost snobs in creation,—are quick to note the difference between a well-clad and a disreputable stranger. Here unquestionably was a visitor:—some such man as so often came to the Place and paid such flattering attention to the puppy. No longer need Lad be bored by the solitude of this particular night. Some one was coming towards the house and carrying a small bag under his arm. Some one to make friends with. Lad was very happy. Deep in his throat a welcoming bark was born. But he stilled it. Once, when he had barked at the approach of a stranger, the stranger had gone away. If this stranger were to go away, all the night’s fun would go with him. Also, no later than yesterday, the Master had scolded Lad for barking at a man who had called. Wherefore the dog held his peace. Getting to his feet and stretching himself, fore and aft, in true collie fashion, the pup gambolled up the drive to meet the visitor. The man was feeling his way through the pitch darkness, groping cautiously; halting once or twice for a smoulder of lightning to silhouette the house he was nearing. In a wooded lane, a quarter mile away, his lightless motor car waited. Lad trotted up to him, the tiny white feet noiseless in the soft dust of the drive. The man did not see him, but passed so close to the dog’s hospitably upthrust nose that he all but touched it. Only slightly rebuffed at such chill lack of cordiality, Lad fell in behind him, tail awag, and followed him to the porch. When the guest should ring the bell, the Master or one of the maids would come to the door. There would be lights and talk; and perhaps Laddie himself might be allowed to slip in to his beloved cave.
