Boulton had already won his way to the very front rank in his calling, honestly and honourably; and he was proud of it. He had created many new branches of industry, which gave regular employment to hundreds of families. He had erected and organised a manufactory which was looked upon as one of the most complete of its kind in England, and was resorted to by visitors from all parts of the world. But Boulton was more than a man of business: he was a man of culture, and the friend of cultivated men. His hospitable mansion at Soho was the resort of persons eminent in art, in literature, and in science; and the love and admiration with which he inspired such men affords one of the best proofs of his own elevation of character. Among the most intimate of his friends and associates were Richard Lovell Edgeworth,[134] a gentleman of fortune, enthusiastically devoted to his long-conceived design of moving land-carriages by steam; Captain Keir, an excellent practical chemist, a wit and a man of learning; Dr. Small, the accomplished physician, chemist, and mechanist; Josiah Wedgwood, the practical philosopher and manufacturer, founder of a new and important branch of skilled industry; Thomas Day, the ingenious author of ‘Sandford and Merton;’ Dr. Darwin, the poet-physician; Dr. Withering, the botanist; besides others who afterwards joined the Soho circle,--not the least distinguished of whom were Joseph Priestley and James Watt.[135] [134] Mr. Edgeworth was first introduced to the notice of Mr. Boulton in the following letter from Dr. Darwin (1767):--“Dear Boulton, I have got with me a mechanical friend, Mr. Edgeworth, from Oxfordshire,--the greatest conjurer I ever saw. God send fine weather, and pray come to my assistance, and prevail on Dr. Small and Mrs. Boulton to attend you to-morrow morning, and we will reconvey you to Birmingham if the devil permit. E. has the principles of nature in his palm, and moulds them as he pleases,--can take away polarity, or give it to the needle by rubbing it thrice on the palm of his hand! And can see through two solid oak boards without glasses! Wonderful! astonishing!! diabolical!!! Pray tell Dr. Small he must come to see these miracles. Adieu, E. Darwin.”
