Other means might be readily devised of increasing the receipts, giving at the same time increased convenience to the public. Thus, from the great extent of the building, and from the crowd, it may become difficult to pass easily from one part of the building to another. Now if the stalls were placed back to back along the centre of the great longitudinal avenues, a railway formed of wooden planks placed edgeways might be raised above the middle of them at a height of about eight feet, which would interfere but little with the stalls. On this open railway cars mounted on wheels bound with india-rubber,[6] in order to avoid all noise, might travel at the rate of from one to two or perhaps three miles an hour. These cars might have luxurious cushions, and hold parties of different numbers. One line in a side aisle, the “express,” might be devoted entirely to conveying passengers from one end to the other at the rate of three miles an hour, setting down at six or more intermediate stations: the payment might be one penny, or perhaps, on grand days, two or three pence. The other lines should take parties slowly along, so as to allow time to see the crowd below and the wonders of the exhibition, which might be rendered more distinct by means of opera glasses. Each trip might occupy twenty minutes or half an hour, and be charged threepence, sixpence, or a shilling, according to the price of admission on that day. By these means multitudes of ladies, children, and even of men, relieved from bodily fatigue, might be able to acquire knowledge or derive pleasure, which without these resources it would be impossible for them to enjoy. It is probable that the light iron framing of such cars might be provided gratuitously by some exhibitors, and the spring cushions and ornamental drapery might be supplied by others, in consideration of the advertisement thus afforded of the purveyor’s taste and skill. The chariots of these railways should be drawn by means of a rope connected with the motive power. If dumb railways are not thought expedient, small galleries at least might be made to which admission should be obtained by a small payment, so that those who wanted to traverse quickly from one part to another of the building, might thus, by avoiding the crowd, save time. Umbrellas, and sticks, and great coats might be taken charge of by ticket on payment of one halfpenny. Also, any visitor might be allowed to deposit on his departure a bag containing his catalogue, note-book, or any articles which it might be inconvenient to him to take home with him each day, as is customary at the railway stations. Other accommodations will suggest themselves, to be provided on the payment of a very small fee; for example, soap and water and a clean towel may be very desirable to some visitors, especially to those who may examine the machinery.
