There are still other claimants for the merit of having invented the planing machine; among whom may be mentioned more particularly Matthew Murray of Leeds, and Richard Roberts of Manchester. We are informed by Mr. March, the present mayor of Leeds, head of the celebrated tool-manufacturing firm of that town, that when he first went to work at Matthew Murray's, in 1814, a planing machine of his invention was used to plane the circular part or back of the D valve, which he had by that time introduced in the steam-engine. Mr. March says, "I recollect it very distinctly, and even the sort of framing on which it stood. The machine was not patented, and like many inventions in those days, it was kept as much a secret as possible, being locked up in a small room by itself, to which the ordinary workmen could not obtain access. The year in which I remember it being in use was, so far as I am aware, long before any planing-machine of a similar kind had been invented."

Matthew Murray was born at Stockton-on-Tees in the year 1763. His parents were of the working class, and Matthew, like the other members of the family, was brought up with the ordinary career of labour before him. When of due age his father apprenticed him to the trade of a blacksmith, in which he very soon acquired considerable expertness. He married before his term had expired; after which, trade being slack at Stockton, he found it necessary to look for work elsewhere. Leaving his wife behind him, he set out for Leeds with his bundle on his back, and after a long journey on foot, he reached that town with not enough money left in his pocket to pay for a bed at the Bay Horse inn, where he put up. But telling the landlord that he expected work at Marshall's, and seeming to be a respectable young man, the landlord trusted him; and he was so fortunate as to obtain the job which he sought at Mr. Marshall's, who was then beginning the manufacture of flax, for which the firm has since become so famous.
