Two splendid marquees were erected at an early hour in the morning--one for the accommodation of the ladies, the other for the dinner party; and two beautiful pleasure-yachts which conveyed a portion of the invited to the scene, rested at anchor in the Sound, and with their white sails and coloured streamers contributed their share of life and beauty to the landscape. Let the reader then imagine what a spectacle was presented when the groups of quadrille-dancers--the beauty and gallantry of the metropolis and its vicinity--commenced dancing on the greensward to the music of one of the finest of military bands--what a delight to the happy multitude of spectators who looked on at the graceful and tempered gaiety of high life! The mind of the accomplished painter Watteau, in his finest pictures of the _fetes champetres_ of the French, never conceived any thing so exquisitely beautiful and romantic. This party did not disperse till after sunset. After an early dinner, dancing was again resumed; and it is worthy of remark that throughout the day there was not a single instance of rudeness or indecorum on the part of the uninvited spectators--no attempt even to approach beyond the natural rocky boundary which they had chosen for themselves--and that the festivities were concluded with mutual pleasure to all the parties who had participated in them. Alas! of the gay party then assembled--the gentle maidens in all the bloom of youthful beauty, the frank young soldiers, the men of fortune, the delighted parents--of all these how many now lie low! More, reader, than you could possibly imagine! Nor can we avoid exclaiming again, alas that such scenes of rational pleasure, in which the higher and the humbler classes came together in healthful and innocent enjoyment, are not now to be seen in our country as they were heretofore!
