“EXPERIMENTAL PAVEMENT OF OXFORD STREET.—This, doubtless, the most extraordinary and novel undertaking which has ever been attempted in the annals of road making, is, to the gratification, not only to the respectable inhabitants of Oxford Street, but to a curious public, at last, completed. On Friday (4 Jan.) at 2 o’clock, the line of this great thoroughfare, occupied by the various specimens of paving, extending from Charles Street to Tottenham Court Road, presented a most animated spectacle, being thronged by thousands of spectators anxious to witness its opening to the public. Shortly after 2 o’clock, the Paving Committee appointed by the Marylebone Vestry to superintend the arrangement of this work of art, headed by the parish beadles, in full uniform, with their maces; and accompanied by the respective projectors and the parochial authorities, arrived on the spot in procession, and passed over the ground, followed by 21 omnibuses, after which, the road was thrown open to the public. From time to time, during the progress of the work, many erroneous statements have gone the rounds of our daily contemporaries, with respect to the extent of ground allotted to the experiments, and on other matters connected with the arrangements. The following, however, being obtained from an official source, may be fully relied upon as correct: The whole space between Charles Street and Tottenham Court Road is occupied by 12 different specimens, which are completed in the following order, commencing at Charles Street: viz.—40 feet of Robinson’s Parisian bitumen—24 feet laid in straight courses, and 16 feet diagonally; 74 feet of parish stone paving, 54 feet of which is laid in straight courses, the stones 9 inches deep, and the interstices filled up with Claridge’s asphalte; the remaining 20 feet consisting of stones only 4½ inches deep, but laid diagonally, and filled up with the same composition; 60 feet of the Bastenne and Gaujac bitumen, partly laid in straight courses, and partly diagonally: 135 feet of parish stone paving, divided into three sections, in the following order—1st, 70 feet of dressed Aberdeen granite, with concrete bottom, and the joints grouted with lime and sand; 2nd, 40 feet of the same, laid diagonally; and 3rd, 25 feet of dressed Aberdeen granite, without concrete bottom, the joints filled in with fine gravel; this is followed by 50 feet of the Scotch asphaltum, which is entirely the produce of this country, laid down in straight courses: 60 feet of Mr. Stead’s pavement, of wooden blocks, of a sexagonal form, 12 inches deep, divided into three compartments, one prepared with Kyan’s patent, part dipped in, and joints run with asphalte, and part without any preparation whatever: the last specimen, at Tottenham Court Road, is 60 feet of the Val de
