At three in the morning,…Shadrach was brought to the Bigelows' house. Mrs. Bigelow was not well. Her husband, however, made a fire in the air-tight stove in her room to get the slave and his rescuer some breakfast, and meanwhile went over to get Mrs. Brooks, a most ardent abolitionist, though law-abiding Squire Brooks said, "But if she is very sick they may want me for something, so I'll go over with you." When there, the door opened, [and when] Mr. Bigelow hear Mr. Brooks' voice down stairs with his wife's, he said, "What shall we do now?" But Mrs. Bigelow said, "There must be no concealment: let Mr. Brooks come up." Mr. Brooks with his wife entered Mrs. Bigelow's chamber and to their surprise found Mr. and Mrs. Bigelow, Mr. — and Shadrach the fugitive. Squire Brooks saw what was going on at once, but here was an abstract matter hitherto now presented to him in the most concrete form.
They were fitting Shadrach out with clothes. Mr. Bigelow's hat wouldn't fit him, but the man of law straightway zealously ran across the road to his house and fetched his own hat, sheltered by which Shadrach departed for the North Star, driven by Mr. Bigelow with a horse got from the stables near by (his own horse was white, well known, and hence unadapted for contraband service) in the wagon of Lowell Fay, another near neighbor.
Next day Mr.Cheney … said sharply to Mr. Brooks, "Shadrach was brought to Concord," which statement the Squire had to bluff off as best he might, but he was now liable to fine and imprisonment for violating the sacred law of the land.
