Pick them up again and tack them on where they were not at all needed

Jack's peculiarities of speech became more pronounced, and the Irish brogue, mixing with the cockney dialect he had picked up in English ships and about the Liverpool and London docks, which was at other times less noticeable, asserted itself more distinctly when he was deeply moved. The cockney features of his dialect were intermittent. Sometimes he would drop his h's all about in a most promiscuous and reckless way and pick them again up and tack them on where they were not at all needed; while at other times - in the same sentence perhaps - he would keep them where they belonged.
