The plan was accepted on the 26th of July, 1850; and Messrs. Fox, Henderson, and Co. became the contractors, for the sum of £79,800, if the materials should remain their property, they being at the expense of removal; or £150,000 if the materials became the property of the Commissioners. It actually cost £176,030. The first column was fixed on the 26th of September, 1850; the contract to deliver over the building complete to the Commissioners on the 31st of December was virtually performed; and on the 1st of January, 1851, the Commissioners occupied the vast space with their carpenters, painters, and various artisans. The Crystal Palace excited universal admiration, from the wonderful combination of vastness and beauty, from its immense magnitude united with lightness, symmetry, and grace, as well as admirable adaptation to its purpose. And when it was fully furnished and open to the public, on the 1st of May, 1851, the visitor felt as if he had entered a fairy-like scene of enchantment, a palace of beauty and delight, such as one might suppose mortal hands could not create. The effect on the beholder far surpassed all that its most sanguine projectors could have anticipated. The scene was impressive on the opening on that beautiful May morning by the Queen and Prince Albert, followed in procession through the building by a long train of courtiers, Ministers of State, foreign ambassadors, and civic dignitaries; while the sun shone brightly through the glass roof upon trees, flowers, banners, and the picturesque costumes of all nations, the great organ at the same time pealing gloriously through the vast expanse, which was filled by a dense mass of human beings, representing the grandeur, wealth, beauty, intelligence, and enterprise of the civilised world. The number of exhibitors exceeded 17,000, of whom upwards of 3,000 received medals. It continued open from the 1st of May till the 15th of October, altogether 144 days, during which it was visited by 6,170,000 persons, giving an average daily attendance of 42,847. The greatest number in one day (October 8th) was 109,760. The greatest number in the Palace at any one time was 93,000, which surpassed in magnitude any number ever assembled together under one roof in the history of the world. The charges for admission were half-a-crown on particular days, and one shilling on ordinary days. The receipts, including season tickets, amounted to £505,107, leaving a surplus of about £150,000, after paying all expenses; so that the Exhibition was in every sense pre-eminently successful. However, it did not, as was anticipated, inaugurate an era of peace.
