It was a small tin cash-box which stood upon the writing-desk. Holmes pried it open with his chisel. Several rolls of paper were within, covered with figures and calculations, without any note to show to what they referred. The recurring words “water pressure” and “pressure to the square inch” suggested some possible relation to a submarine. Holmes tossed them all impatiently aside.
