HAS HE A SIXTH SENSE?
He reads and understands the most delicate intonations and modulations of voices addressing him, as others read and understand facial expression. His sensitive fingers detect differences in metals, and follow, as if with a gift of perception, the lines of models submitted to him, and his mind sees even more clearly than by mere physical sight the intricacies of the most complicated machinery intelligently described to him, or over which his fingers are allowed to move. “That is a good stick,” he will say, examining a pile of lumber with his fingers. “Here’s a shaky piece, throw it out; it won’t do for this work,” may come next, or, “Saw off this end; it’s poor stock. The rest is all right.” On hearing him criticize, direct, and explain things within his province, a stranger finds it hard to believe he cannot see at least a little,—out of one eye.
