Besides which it may be mentioned that special Commissioners have been sent to this country by France, Russia, and one or two other States; and that in most cases the Governments have undertaken the collection and the transmission to this country, at their own expense, of the articles intended for exhibition, for which, of course, their preparations are now made.

18. In all the countries which have been mentioned active preparations for the Exhibition are now going on, and in some considerable expense is known to have been incurred. The Russian Government has announced that the goods intended for exhibition will be shipped from that country in the autumn of this year, and questions pointing to a similar arrangement have recently been put by the Government of Denmark. The Austrian Government have given notice, that the Great Exhibition which was to have been held at Vienna in the year 1851 has been postponed till the year 1852, in order not to clash with the Exhibition in London. All these circumstances tend to show that the postponement of the Exhibition would be seriously inconvenient to many countries, and would probably occasion considerable and natural irritation at what would appear like national vacillation, besides the certainty of rendering these countries unwilling to run the risk of a second disappointment, and of deterring them from continuing their preparations for a later period.

19. These inconveniences would be felt also by the British Colonies. Committees have been announced as formed in Malta, Ceylon, Nova Scotia, Barbadoes, Guiana, and several of the West India Islands, and it is probable that others have been appointed elsewhere. In India most extensive preparations are being made, and the East India Company have incurred very great expense by their exertions to contribute to the Exhibition.

20. After what has been said, it is unnecessary that the Commissioners should enlarge any further upon the consequences to be apprehended from the postponement which would be occasioned by an alteration of the site of building. They will proceed to offer a few remarks upon some of the objections which have been taken to that at present proposed.

21. An idea appears to prevail in some quarters that the occupation of the Park is intended to be of a permanent, and not, as has been repeatedly announced, of a merely temporary character, and the Commissioners are given to understand that by proposing to construct a building into which a good deal of brickwork is to enter, they have shown an intention at variance with their professions. Upon this point they have to remark, in the first place, that, although the eminent architects and engineers whom they have consulted, and to whom they have uniformly given instructions to prepare plans suitable to a temporary structure, have agreed to recommend the use of brick and other durable materials, they have left it perfectly open to contractors to send in their tenders for the execution of the work in any material or materials whatsoever, and have notified their readiness to entertain such tenders, on the single condition of their being "accompanied by working-drawings and specifications, and fully priced bills of quantities." It is probable that some such tenders will be made, and if made they will be impartially considered; but the Commissioners must protest against the supposition that it is necessarily more judicious to construct a temporary building of perishable than of enduring materials. The first requisite of the building is, that it should be suitable for its purpose, capable of protecting the valuable goods deposited in it from injury of every kind—as, for instance, from the weather, from the effects of the dampness of the soil, from the danger of fire, and so forth, and that it should be strong enough to avert all risk of accidental damage. Its next requisite is, that it should be economical, and in estimating its cost regard must be had not only to the expense of erection, but to the facility of removal and the value of the materials when removed, as a building may easily be conceived to be cheaper which should cost 100,000l. to erect, but of which the materials could afterwards be sold for 50,000l., than another would be which cost but 80,000l. in the first instance, but of which the materials should become so far deteriorated as to produce only 20,000l. when taken down. It is the opinion of those who have devised the plans in the present case, that a building constructed of durable materials will in the end be cheaper than one constructed of such as are more perishable; particularly as a considerable portion of the building, namely, the iron roofing, will be of a kind which is generally used in the construction of railway-stations, and will probably be disposed of for that purpose after the close of the Exhibition, as its temporary application to the purposes of the Exhibition will be of no detriment to its being so. An opportunity of testing the correctness of this opinion will be given when the tenders are received, as, in addition to the customary form, it has been required that they should also be sent upon the understanding that the materials shall remain the property of the contractor, and shall in fact only be hired for the purposes of the Exhibition. The third requisite of the building is, that it should be at least seemly, though it may not be necessary that it should be highly ornamental. The Commissioners trust that it will fulfil this condition, while they would at the same time point out that no expense is to be incurred for merely ornamental purposes, unless it should be thought desirable to select a dome for covering in the large space which must necessarily be left in the centre of the building to suit the internal arrangements. A cheaper mode of covering in this space will probably be resorted to, and the Commissioners have directed that a special estimate of the cost of the dome should be laid before them when the tenders are complete, in order that they may judge of the propriety of sanctioning its erection.

Having offered this short explanation, they can only repeat once more the assurances they have already given, that the building is not intended to be permanent, and that it will be entirely removed, in accordance with the conditions prescribed by the Lords of the Treasury on yielding up the site, within seven months after the closing of the Exhibition, which cannot be deferred after the 1st of November, and will probably take place at an earlier period in the autumn of next year.

22. Another ground of apprehension is stated to be, lest the Park should be injured by the erection of the building, and the injury should continue after the structure is removed. This apprehension is, however, groundless; a small clump of ten trees has been allowed to be removed, in compensation for which, it is proposed by the Commissioners of Woods and Forests to plant another clump elsewhere. It is not intended to cut down any more than that clump. As regards the surface of the ground to be occupied, it will not only not be injured, but will ultimately be materially improved by being drained and freshly sown with grass seed. It will be a strict condition with the contractors for the building that they shall, on its removal, restore the ground to its present condition.

23. Some dissatisfaction has been expressed at the prospect of a furnace being erected to heat the boiler and drive the steam-apparatus. It is however, intended to construct such furnace on the principle of consuming its own smoke, or to burn coke instead of coal, should that, upon the whole, appear the best mode of preventing annoyance. Care will also be taken not to erect any chimney of an unsightly character.

24. As regards the amount of traffic which will be occasioned by the transport of materials and goods to the site, the Commissioners have been furnished by the Building Committee with an approximate estimate that it will not in the whole exceed the ordinary amount of three weeks' general traffic of a single railway-station, and as this traffic will be spread over a period of more than six months, it is manifest that its amount has been enormously exaggerated by public estimation.
