Perhaps on a future occasion some such scheme of admission as the following might be found most productive. After the exceptional days at the commencement, occupying the first fortnight, the admission might be charged thus:— May June July Aug. Sept. Oct. s. d. s. d. s. d. s. d. s. d. s. d. Mon. 1 0 1 0 1 0 0 6 0 6 0 3 Tues. 10 0 5 0 2 6 2 0 1 6 1 0 Wednes. 5 0 2 6 1 6 1 0 1 0 0 6 Thurs. 2 6 1 0 1 0 1 0 0 6 0 3 Frid. 1 0 1 0 1 0 0 6 0 6 0 3 Sat. 1 0 1 0 0 6 0 6 0 3 0 3 The principle of this scale is, that each week day shall gradually diminish in actual price, but shall always preserve its relative price. Thus Tuesday is always the day of dearest admission, Wednesday of the next dearest, whilst Saturday is always the day of cheap admission. These periods might be distributed by weeks instead of months. Whatever arrangement is made as to the price of admission, it is of very great importance that the number of visitors at the various prices should be noted and recorded for future use. It will indeed be unfortunate if knowledge so important for any similar occasion, should not be registered on the present. For this purpose _every_ entrance should have one or more self-acting turnstiles registering the number of those who pass through it. Not only the public who pay, but the exhibitors and all who have free admissions should be registered. At the end of each hour, when the clock strikes, each gate-keeper should enter in a book the number indicated by his register. Such a collection of facts, extending over the whole time of the Exposition, would not only be invaluable for any future one, but would furnish materials for other important inquiries. The general state of the weather, which of course would have a powerful influence, might be known from other registers: but it would be advisable that at the end of each day some note were made of the general state of the weather at the Crystal Palace itself. § After the first of these Expositions it seems probable that their advantages will become so well known, that it may be quite possible to let out the stalls to exhibitors under certain conditions. Foreigners might still be admitted to exhibit without payment, because the expense of carriage would more than compensate for the rent. Some stalls might be granted without rent by the Commissioners, the peculiar circumstances of each case having been considered. Again, other stalls, or at least other means of exhibition, might be accorded to those who contributed articles of actual use in the building; as for example, a large striking clock, a steam-engine to drive the machinery or to supply the fountains.
