They found a portion of a Roman building, but the greatest haul was in an old gravel pit, some 50ft. by 34, filled with hardened mud, in which were contained considerable quantities of animal and vegetable remains, apparently the discarded refuse of the inhabitants of the vicinity. In the same depository were also found very numerous fragments of the red Roman pottery, usually called “Samian Ware,” pieces of glass vessels, broken terra-cotta lamps, parts of amphoræ, mortaria, and other articles made of earth, and all the rubbish which might naturally become accumulated in a pond in the course of years. In this mass likewise occurred a number of Imperial Roman coins, several bronze and iron styles, parts of writing tablets, a bather’s strigil, a large quantity of caliga soles, sandals and remains of leather, all of which can now be seen in the highly interesting Museum of the Corporation of the City of London, at the Guildhall. CHAPTER XVII. Foundation of Royal Exchange laid—Medal connected therewith—Father Mathew’s miracle—Christening of the Prince of Wales—King Edward VII.—Hard work of the King of Prussia—The Earthquake in London—The Queen drinking “grog”—Photography-Talbotype—Sale at Strawberry Hill—Presents to the King of Prussia. The first event of note in this year was the laying, by Prince Albert, of the foundation stone of the Royal Exchange, on 17 Jan., with all the pomp at the command of the City authorities. The usual coins, etc., were deposited in a cavity, together with a Latin inscription, engraved on zinc, of which the following is a translation: “Sir Thomas Gresham, Knight, erected, at his own charge, a building and colonnade for the convenience of those persons who, in this renowned Mart, might carry on the commerce of the World, adding thereto, for the relief of indigence, and for the advancement of literature and science, an Almshouse and College of Lecturers, the City of London aiding him, Queen Elizabeth favouring the design; and, when the work was complete, opening it in person with a solemn procession. Having been reduced to ashes with almost the entire city, by a calamitous and wide spreading conflagration, they were rebuilt in a more splendid form by the City of London and the Ancient Company of Mercers, King Charles II. commencing the building on 23 Oct., A.D. 1667; and, when they had been again destroyed by fire, on the 10th Jan., AD. 1838, the same Bodies, undertaking the work, determined to restore them at their own cost, on an enlarged and more ornamental plan; the munificence of Parliament providing the means of extending the site, and of widening the approaches and crooked streets, in every direction; in order that there might, at length, arise, under the auspices of Queen Victoria, built a third time from the ground, an Exchange, worthy of this great Nation and City, and suited to the vastness of a Commerce extending to the circumference of the habitable Globe.
