_April 29th._--The Duke was carried off at an early hour to begin the work of the day, into which was to be crammed many inspections and sights. These tell on the tourists somewhat; for as we are handed over, day after day, from one important body of ever kind and indefatigable guides and hosts, we are, of course, paying with our persons, whereas, for those on whom we descend there is but a few hours' hard labour, and then comes repose to them and "good-bye" to us. There is an eminently respectable air about Philadelphia; the shops in the main streets are attractive and beautiful; the citizens look prosperous; the vehicles are soberly luxurious, and the horses sleek. The Auditor, who belongs to the Society of which the founder of the State and city was the great ornament and chief, finds himself at home among many "Friends," and albeit they do not generally affect the attire of the sect, and the broad-brimmed hats, upright collars, single-breasted coats, and knee-breeches of sober hue, of the men, and the coal-scuttle bonnets, square, plain collars, and straight-cut cloth dresses of the women, have given place to garments of modern fashion, the good people called Quakers still form a numerous and influential community.

A. Childs; Vice-Presidents Cassatt, Kneass, and Strickland; Mr. Dubarry, President of the Philadelphia and Erie Company; a number of directors--Messrs. Morris, Felton, Biddle, Shortridge, Cummins, Welsh, &c.--of the main line; Mr. Hinckley, President of the Philadelphia, Wilmington, and Baltimore Company; Mr. Griscom, of the International Navigation Company; Mr. Drexel, and many others, to do them honour. The drawing-rooms of the cars were ornamented with bouquets of the most lovely flowers; it is a never-failing and always welcome compliment, and Americans rival Parisians in the love, skill, and taste they display in the arrangement of these floral triumphs. The party visited Greenwich Point and Girard Point, and I saw with alarm
