On another occasion, Robert played a series of tricks of a somewhat different character. Like his father, he was very fond of reducing his scientific reading to practice; and after studying Franklin’s description of the lightning experiment, he proceeded to expend his store of Saturday pennies in purchasing about half a mile of copper wire at a brazier’s shop in Newcastle. Having prepared his kite, he sent it up in the field opposite his father’s door, and bringing the wire, insulated by means of a few feet of silk cord, over the backs of some of Farmer Wigham’s cows, he soon had them skipping about the field in all directions with their tails up. One day he had his kite flying at the cottage-door as his father’s galloway was hanging by the bridle to the paling, waiting for the master to mount. Bringing the end of the wire just over the pony’s crupper, so smart an electric shock was given it, that the brute was almost knocked down. At this juncture the father issued from the door, riding-whip in hand, and was witness to the scientific trick just played off upon his galloway. “Ah! you mischievous scoondrel!” cried he to the boy, who ran off. He inwardly chuckled with pride, nevertheless, at Robert’s successful experiment. {57} [Picture: Stephenson’s Cottage, West Moor] At this time, and for many years after, Stephenson dwelt in a cottage standing by the side of the road leading from the West Moor colliery to Killingworth. The railway from the West Moor Pit crosses this road close by the east end of the cottage. The dwelling originally consisted of but one apartment on the ground-floor, with the garret over-head, to which access was obtained by means of a step-ladder. But with his own hands Stephenson built an oven, and in the course of time he added rooms to the cottage, until it became a comfortable four-roomed dwelling, in which he lived as long as he remained at Killingworth. He continued as fond of birds and animals as ever, and seemed to have the power of attaching them to him in a remarkable degree. He had a blackbird at Killingworth so fond of him that it would fly about the cottage, and on holding out his finger, would come and perch upon it. A cage was built for “blackie” in the partition between the passage and the room, a square of glass forming its outer wall; and Robert used afterwards to take pleasure in describing the oddity of the bird, imitating the manner in which it would cock its head on his father’s entering the house, and follow him with its eye into the inner apartment.
