I have endeavoured, but without much success, to collect information respecting this very extraordinary man. It appears that his father and mother, whose maiden name was Rodda, were in a situation of life raised above the common level, and that they bestowed on their son the best education easily attainable, who on his part became eminently distinguished among his companions. If young Lemon ever, therefore, employed himself in executing the inferior labours usually performed by mining boys, as some have alleged with the view of increasing the wonder of his subsequent progress, and others impelled by less laudable motives, it is clear that they must have been undertaken from a desire of making himself practically acquainted with all the details of perhaps the most delicate operations in metallurgy. His bodily strength and firmness of mind seem to have been commensurate with those abilities, which displayed themselves most conspicuously in after life. Within my recollection, the people of Breage and Germoe were fond of relating that Squire Lemon in his youth made the foremost link of a living chain, which, connected only by the grasp of their hands, extended itself into a tremendous surf, and rescued various human beings from a watery grave. At a very early age, Mr. Lemon became one of the managers of a tin-smelting house at Chiandower, near Penzance; and the career which he pursued with so much ability and success, was traced for him at this place. The ancient mining of Cornwall, like that of Banka in the present day, had been confined for a long succession of ages to merely collecting diluvial deposits of tin ore, which, from its great specific gravity, is always found beneath every other debrit, and immediately incumbent on the solid rock, or unmoved strata, provincially called “the Fast.” As the first operation invariably consists in washing away the lighter ingredients, by agitating the whole in streams, which never fail of gliding through the vallies where alone these deposits are found, the name “stream-work” has been adopted, to distinguish these sources of tin from mines which descend on the lodes themselves. Mines invariably grew out of the stream-works, but with a progress so very slow as scarcely to be imagined by persons conversant only with the rapid improvements of modern times. Pits were at first sunk on the backs of lodes, till the presence of water impeded the work. Shallow adits, or drains, were obviously used in favourable situations, and the windlass, with its bucket and rope, must be of great antiquity. To this succeeded the rack and chain pump, identical with those still used in large ships; but the span beam and cage, moving on a perpendicular axis, by which the labour of horses became applicable to what had previously been done by the human arm, are so very modern, that the Editor remembers a carpenter who used to boast that he assisted in making the first whim ever seen westward Hayle.
