The gullibility of Martin Harris is illustrated by his response to Smith locating a dropped toothpick:
“I was at the house of his father in Manchester, two miles south of Palmyra village, and was picking my teeth with a pin while sitting on the bars. The pin caught in my teeth, and dropped from my fingers into shavings and straw. I jumped from the bars and looked for it. Joseph and Northrop Sweet also did the same. We could not find it. I then took Joseph on surprise, and said to him–I said, ‘Take your stone.’ I had never seen it, and did not know that he had it with him. He had it in his pocket. He took it and placed it in his hat– the old white hat–and placed his face in his hat. I watched him closely to see that he did not look one side; he reached out his hand beyond me on the right, and moved a little stick, and there I saw the pin, which he picked up and gave to me. I know he did not look out of the hat until after he had picked up the pin.”
