The fearlessness and firmness of character, which he inherited from both father and mother, manifested itself in many ways. He had a lamb, whose horns were crooked, and had a tendency to turn in. His father had given it to him for his own, on condition that he should keep the horns carefully filed, so that they should not hurt the animal. He had a small file on purpose, and took such excellent care of his pet, that it soon became very much attached to him, and trotted about after him like a dog. When he was about five or six years old, British soldiers came into the neighborhood to seize provisions for the army, according to their custom during our revolutionary war. They tied the feet of the tame lamb, and threw it into the cart with other sheep and lambs. Isaac came up to them in season to witness this operation, and his heart swelled with indignation. He sprang into the cart, exclaiming, "That's _my_ lamb, and you shan't have it!" The men tried to push him aside; but he pulled out a rusty jack-knife, which he had bought of a pedlar for two-pence, and cut the rope that bound the poor lamb. A British officer rode up, and seeing a little boy struggling so resolutely with the soldiers, he inquired what was the matter. "They've stolen my lamb!" exclaimed Isaac; "and they shan't have it. It's _my_ lamb!" "_Is_ it your lamb, my brave little fellow?" said the officer. "Well, they shan't have it. You'll make a fine soldier one of these days." So Isaac lifted his lamb from the cart, and trudged off victorious. He had always been a whig; and after this adventure, he became more decided than ever in his politics. He often used to boast that he would rather have a paper continental dollar, than a golden English guinea. The family amused themselves by exciting his zeal, and Polly made him believe he was such a famous whig, that the British would certainly carry him off to prison. He generally thought he was fully capable of defending himself; but when he saw four soldiers approaching the house one day, he concluded the force was rather too strong for him, and hastened to hide himself in the woods. His temper partook of the general strength and vehemence of his character. Having put a small quantity of gunpowder on the stove of the school-house, it exploded, and did some injury to the master. One of the boys, who was afraid of being suspected of the mischief, in order to screen himself, cried out, "Isaac Hopper did it!"--and Isaac was punished accordingly. Going home from school, he seized the informer as they were passing through a wood, tied him up to a tree, and gave him a tremendous thrashing. The boy threatened to tell of it; but he assured him that he would certainly kill him if he did; so he never ventured to disclose it.
