"The third, FACILITIES FOR THE CIRCULATION OF VISITORS, is thus attained. The visitor, on arrival at the central hall, proceeds at choice to any one of the four sections. He will, most probably, desire either to follow the whole course of the section selected, or will wish to go at once to some particular class or object. He will be enabled to do either the one or the other, without interfering with the general current, by means of gates or other arrangements, which shall insure the current of visitors passing in one direction. If he desire to proceed rapidly from one end of the building to the other, and finds the great central gangway at all blocked up, he will, no doubt, be able to get on by either the north or south corridors, fifteen feet wide. Numerous doors of egress in these latter afford ready means of exit for a large number of persons. Seats are provided in the middle of the great central gangway for those who may desire to rest. "The fourth, ARRANGEMENT FOR GRAND POINTS OF VIEW. The view from or to the centre of the building will, from its extent, be necessarily imposing. The seats and main avenues are arranged so that, on the occasion of the distribution of the prizes, an immense number of persons may be accommodated. Most interesting views might be obtained from galleries constructed at either end of the building and around the dome, for the admission of the public to which some small charge might be made. "The fifth, CENTRALISATION OF SUPERVISION. All the business of the Exhibition will be carried on in one spot, and be readily under control. The Royal Commission, the principal Committees, Clerks, Accountants, Police, &c., would be together, and in so large an establishment it would be absolutely necessary, or much time would be wasted in walking from one point to another. Passages running behind the money-takers' boxes, with glazed doors into them, would enable each accountant to detect anything improper that might be going on, and to exchange and balance checks, money, &c., at any moment. Telegraphic communication with each of the four pay-places will permit orders to be given, cash accounts, &c., to be issued and returned, from and to the head-accountant's office, as often as may be necessary. "Four Committee-rooms, one for a Jury in each section, have been provided at the extreme east and west ends. The duties of such Committees being deliberative, and not executive, it is not necessary that they should be accommodated in the Central Establishment, where they would be more liable to be disturbed than at the extremity of the building. "A policeman stationed in each gallery would, from his elevated position, be enabled to observe much which might escape detection if he mingled only with the crowd.
