Mr. Sumner arrived in this vicinity on Sunday morning, November 2d. On Monday he drove from Professor Longfellow’s, in Cambridge, where he had been staying, to the house of Amos A. Lawrence, Esq., at Longwood, in Brookline. Soon after one o’clock, the invited guests, who had assembled at the State House, proceeded in open carriages to Longwood, where they were joined by Mr. Sumner, who passed along the line of carriages, and was silently greeted by the gentlemen rising and removing their hats. The carriages then proceeded across to Roxbury, and thence along Washington Street to the Boston line, which was reached at three o’clock. Here the cavalcade was assembled, together with a vast concourse of citizens. The chief marshal was General John S. Tyler, assisted by the following gentlemen as aids: Major John C. Park, Colonel R. I. Burbank, Major Moses G. Cobb, E. Webster Pike, Esq., Adjutant-General E. W. Stone, Colonel A. J. Wright, Colonel W. W. Bullock, and Carlos Pierce, Esq. The following were the assistant marshals: Captain I. F. Shepard, Charles H. Hawes, W. E. Webster, F. L. Chapin, O. H. Dutton, Major F. A. Heath, F. B. Fay, Julian O. Mason, A. A. Dunnels, Stephen Rhoades, H. D. Child, Leister M. Clark, Charles W. Pierce, R. F. Martin, Rufus Frost, F. A. Fuller, J. W. Wolcott, William B. Spooner, Henry D. Williams, Colonel Robert Cowdin, of Boston, and Eugene Batchelder, Charles D. Hills, D. P. Ripley, of Cambridge. As it went up Washington Street, the cavalcade numbered, by actual count, about eight hundred horsemen; but its numbers were subsequently increased by fresh arrivals, in couples and in groups, to over a thousand. On the head of the cavalcade reaching the borders of Roxbury, it halted, and the whole was drawn up in a long line at the upper side of Washington Street, facing the centre. For over half an hour it waited for the cortege from Brookline which was to escort Mr. Sumner, and when at last the latter appeared, it was received with hearty cheers and music from the Brigade Band. It consisted of some sixteen or eighteen barouches or carriages, containing the Committee of Arrangements and other gentlemen.
