They had a bond of union in certain common friends whom they much loved, and with whom they much associated. At least these friends soon became common to them. The acquaintance originally belonged to Norman, and he had first cemented his friendship with Tudor by introducing him at the house of Mrs. Woodward. Since he had done so, the one young man was there nearly as much as the other. Who and what the Woodwards were shall be told in a subsequent chapter. As they have to play as important a part in the tale about to be told as our two friends of the Weights and Measures, it would not be becoming to introduce them at the end of this. As regards Alaric Tudor it need only be further said, by way of preface, of him as of Harry Norman, that the faults of his character must be made to declare themselves in the course of our narrative. CHAPTER II THE INTERNAL NAVIGATION The London world, visitors as well as residents, are well acquainted also with Somerset House; and it is moreover tolerably well known that Somerset House is a nest of public offices, which are held to be of less fashionable repute than those situated in the neighbourhood of Downing Street, but are not so decidedly plebeian as the Custom House, Excise, and Post Office. But there is one branch of the Civil Service located in Somerset House, which has little else to redeem it from the lowest depths of official vulgarity than the ambiguous respectability of its material position. This is the office of the Commissioners of Internal Navigation. The duties to be performed have reference to the preservation of canal banks, the tolls to be levied at locks, and disputes with the Admiralty as to points connected with tidal rivers. The rooms are dull and dark, and saturated with the fog which rises from the river, and their only ornament is here and there some dusty model of an improved barge. Bargees not unfrequently scuffle with hobnailed shoes through the passages, and go in and out, leaving behind them a smell of tobacco, to which the denizens of the place are not unaccustomed. Indeed, the whole office is apparently infected with a leaven of bargedom. Not a few of the men are employed from time to time in the somewhat lethargic work of inspecting the banks and towing-paths of the canals which intersect the country. This they generally do seated on a load of hay, or perhaps of bricks, in one of those long, ugly, shapeless boats, which are to be seen congregating in the neighbourhood of Brentford. So seated, they are carried along at the rate of a mile and a half an hour, and usually while away the time in gentle converse with the man at the rudder, or in silent abstraction over a pipe.
