James Nasmyth Engineer An Autobiography

On the following day I was taken a round of the ironworks, and inspected their machinery, as well as that of the collieries, in the details of which Mr. Hartop had introduced many common-sense and most effective improvements. All of these interested me, and gave me much pleasure. In the evening we resumed our "cracks" on many subjects of mutual interest. The daughter joined in our conversation with the most intelligent remarks; for, although only in her twenty-first year, she had evidently made good use of her time, aided by her clear natural faculties of shrewd observation. Mr. Hartop having met with some serious reverse of fortune, owing to the very unsatisfactory conduct of a partner, had in a manner to begin business life again on his own account.
