[The following report of the proceedings at the Thanksgiving Dinner in London arrived too late to be incorporated in the body of THE CONTINENTAL; in consequence, however, of its immediate interest to our readers, we have decided upon giving it to them, even if it must appear as a supplement. It is surely a very pleasant thing to know that our patriots abroad consecrated the festival by grateful thanks to the Giver of all good; and that public and loyal utterances were made of the great national truths which, in our present crisis, it is of such vital importance to make known to the men and governments of other countries.--ED. CONTINENTAL.] In pursuance of the proclamation of the President of the United States, addressed to all citizens, at home and abroad, the loyal Americans now in England, to the number of several hundred, assembled at St. James Hall to dinner. The Hon. Robert J. Walker presided, assisted by Hon. Freeman H. Morse (our Consul here), and Girard Ralston, Esq. On the right of Mr. Walker sat the American Minister, Mr. Adams, and on the left, George Thompson, Esq., late M. P. from London. After the reading of the proclamation, the prayer, and the hymn, Mr. Walker addressed the company as follows: LADIES AND GENTLEMEN: By the request of my countrymen, I shall preface the toasts prepared for the occasion, by a few introductory remarks. This day has been set apart by the President of the United States for thanksgiving to Almighty God for all the blessings which he has vouchsafed to us as a people. Among these are abundant crops, great prosperity in all our industrial pursuits, and a vast addition, even during the war, to our material wealth. Our finances have been conducted with great ability and success by the Secretary of the Treasury, Mr. Chase, who has also succeeded in giving us, for the first time in our history, a uniform national currency, which, as a bond of union, and as an addition to our wealth and resources, is nearly equal to all the expenses of the great contest. During the present year, nearly 400,000,000 of dollars of the six per cent. stock of the United States has been taken at home, at or above par; whilst, within the last few months, European capitalists, unsolicited by us, are making large investments in the securities of the Union. But, above all, we have to thank God for those great victories in the field, which are bringing this great contest to a successful conclusion.
