4th. A transcript to meander through the centre of the building, with a knave to right and left. Cucumber pumps of the _Louis Quatorze_ pattern on the east and west detours, alternating with eight green cellar doors, to give the same effect and finish which marked the _tout ensemble_ of the Vienna buildings. A main curricle on the right to be flanked by iron decades, with arched approaches for bipeds, tripods, and quadrilaterals. 5th. The general appearance of the exterior to favor the Polynesian style, which is replete with architectural beauties. _Fac similes_ of the Tower of Babel, Tower of London, Leaning Tower of Pisa, and Tower Hall, to adorn the four corners. The trusses and bandages supporting the roof, to be of purple and fine linen, with brass mountings. The roof itself to be perpetually covered with wet towels, to guard against sunstroke. 6th. The centre aisle to be covered with canton flannel matting, with the grass sloping up to the back door. Nineteen hotel candles to illuminate the ground floor, with a citrate of magnesia light in the attic window. This extraordinary structure was completed according to agreement, and upon being weighed at the corner grocery, kicked the beam at 1234567890 pounds, 19 shillings and sixpence. Mr. Dobbins was also entrusted with the erection of MEMORIAL HALL. This is a permanent building, so adapted that it may be used hereafter as an Art Gallery or a Station-house. The foundation is not only cemented with Spalding’s glue, but the iron posterns run through to China, and are tied on the other side with the back hair of coolies, detailed for the service through the courtesy of the Pekin government. [MORITURI SALUTAMUS.] Notwithstanding Mr. Dobbins’ immense labors in completing these two buildings, he still found time to run over to Rome and purchase the Colosseum. He brought it home with him for the purpose of exhibiting Prince Bismarck and the Pope in gladiatorial contests during the exhibition months. [Illustration] * * * * * The contract for MACHINERY HALL was awarded to Mr. Philip Quigley, of Wilmington, Delaware. When it grew too big for his State, he removed it to and finished it upon the ground it occupied. The machinery exhibited was worked by forty horse-power, and a neat stable was attached to the rear for the care and accommodation of the forty horses, the contribution of the city passenger railway companies.
