of the idiosyncrasy of the etcher, it is, of its very nature, incomplete, and acts but as herald to proclaim the greater results to be obtained by following out the art to its proper goal. The great impetus which Bewick's genius gave to the art of wood engraving at the commencement of the present century was carried onwards by his distinguished pupils Luke Clennell, Charlton Nesbitt, and William Harvey, the latter of whom, in 1821, cut the large block of the death of Dentatus (15 in. × 11-1/4 in.) from the picture of the erratic genius B. R. Haydon, under whom he was at that time studying drawing. Robert Branston, John Thompson and his brother Charles,[70] Jackson, and W. J. Linton, are names of equal renown; in fact, during the first half of the century, England may be said to have been supreme in the art. Gradually, however, the various mechanical processes for facilitating the commercial extension of the art such as electrotyping,[71] photography, &c., brought here, too, their deteriorating effects, causing the engraver to become less of an artist and more of a mechanic. In delicacy of work and elaboration of detail, American artists now stand first among wood engravers; but they attempt too much with the means at their command, and try to produce upon the comparatively soft material, wood, the delicate fineness of line which can only be realised in perfection on metal. The extreme closeness of the lines, combined with the exigencies of rapid surface printing, dull more or less the minute interstices which ought to show pure white; effect is lost, and, notwithstanding the excellence of the workmanship, the result becomes monotonous and wearying rather than pleasurable to the satiated eye. In etching also America takes high rank; in addition to Mr. Whistler, the names of Messrs. J. Gadsby Chapman, Gifford, Duveneck, F. S. Church, Pennell, Stephen Parrish, and Mr. and Mrs. Moran, are well known in Europe.
