Little Dave Morgan lived in North Wales. His father kept a great any goats. They used to climb up and down these high mountains, and leap from crag to crag, where no other animal would dare to go. On Dave's sixth birthday, his father brought down from the mountains a pair of twin kids for his present. One was pure white, with buff ears, and Dave named her "Snow-drop." The other, a beautiful gray, shaded with black, he named "Billy." He petted and fed them so they soon grew fat and saucy. I have no doubt Billy really liked his little sister, but he delighted in teasing her whenever he could get a chance.
In Wales there are many mountain streams, narrow, but very deep. The only foot-bridge over some of these streams is a plank, or trees laid side by side. There was one stream which this little brother and sister often crossed, Billy going first.
