On an extensive plot of ground, lying somewhere between the Thames and the Kensington squares, stood the premises of Messrs. Nockett and Perch, builders and contractors. The yard with its workshops formed part of one of those frontier lines between mangy business and garnished domesticity that occur in what are called improving neighbourhoods. We are accustomed to regard increase as the chief feature in a great city's progress, its well-known signs greeting our eyes on every outskirt. Slush- ponds may be seen turning into basement-kitchens; a broad causeway of shattered earthenware smothers plots of budding gooseberry-bushes and vegetable trenches, foundations following so closely upon gardens that the householder may be expected to find cadaverous sprouts from overlooked potatoes rising through the chinks of his cellar floor. But the other great process, that of internal transmutation, is not less curious than this encroachment of grey upon green. Its first erections are often only the milk-teeth of a suburb, and as the district rises in dignity they are dislodged by those which are to endure. Slightness becomes supplanted by comparative solidity, commonness by novelty, lowness and irregularity by symmetry and height. An observer of the precinct which has been named as an instance in point might have stood under a lamp-post and heard simultaneously the peal of the visitor's bell from the new terrace on the right hand, and the stroke of tools from the musty workshops on the left. Waggons laden with deals came up on this side, and landaus came down on the other--the former to lumber heavily through the old-established contractors' gates, the latter to sweep fashionably into the square. About twelve o'clock on the day following Lord Mountclere's exhibition of himself to Christopher in the jeweller's shop at Melchester, and almost at the identical time when the viscount was seen to come from the office for marriage-licences in the same place, a carriage drove nearly up to the gates of Messrs. Nockett and Co.'s yard. A gentleman stepped out and looked around. He was a man whose years would have been pronounced as five-and-forty by the friendly, fifty by the candid, fifty-two or three by the grim. He was as handsome a study in grey as could be seen in town, there being far more of the raven's plumage than of the gull's in the mixture as yet; and he had a glance of that practised sort which can measure people, weigh them, repress them, encourage them to sprout and blossom as a March sun encourages crocuses, ask them questions, give them answers--in short, a glance that could do as many things as an American cooking-stove or a multum-in-parvo pocket-knife. But, as with most men of the world, this was mere mechanism: his actual emotions were kept so far within his person that they were rarely heard or seen near his features.
