The Peace of 1763 was celebrated with uncommon splendour throughout Europe, and particularly in St. James's Park, where a grand fire-work was exhibited. Our amiable Queen, animated by the same impulse, contrived an amusement for his Majesty on his birth-night equally calculated to surprise and please. The Queen induced her royal consort to pass several days previous to the 4th of June at St. James's; and in that interval a great number of persons were employed in preparing a superb temple and bridge, to be illuminated with upwards of 4000 lamps, in the gardens of Buckingham-house. Such was the secrecy used, that the King entertained not the least suspicion of the design in progress, and was consequently astonished on returning to the above palace at ten o'clock, when the window-shutters were suddenly thrown open, at the brilliancy of the scene, which presented an orchestra containing upwards of fifty performers led by Dr. Boyce, amongst whom were the most eminent singers of the day, and the front of a temple ornamented with emblematic paintings conveying the most grateful intimations. The following article, extracted from the London Chronicle for August 1763, must produce a sensation of regret in the recollection of those who were partial to the amusements of Ranelagh: "The only defect in the elegance and beauty of the amphitheatre at Ranelagh, is an improper and inconvenient orchestra, which, breaking into the area of that superb room about twenty feet farther than it ought to do, destroys the symmetry of the whole, and diffuses the sound of the musick with such irregular rapidity, that the harmonious articulations escape the nicest ear, when placed in the most commodious attitude: it also hurts the eye upon your first entry. "To remedy these defects, a plan has been drawn by Messrs. Wale and Gwin, for adding a new orchestra, which, being furnished with a well-proportioned curvature over it, will contract into narrower bounds the modulations of the voice, and render every note more distinctly audible. It will by its form operate upon the musical sounds in the same manner as concave glasses affect the rays of light by collecting them into a focus. The front of this orchestra being planned so as to range parallel to the balustrade, the whole area also will be disencumbered of every obstruction that might incommode the audience in their circular walk. There is likewise provision made in this plan for a stage capable of containing 30 or 40 performers, to officiate as chorus-singers, or otherwise assist in giving an additional solemnity on any extraordinary occasion." This, or a similar plan, was afterwards adopted.
