The attention oi our readers is particular ly directed to the following correspondence between Messrs. Wood, Light, & Co., manu facturers ol machinery, Worcester, Mass., and the managers of the Crystal Palace : " WORCESTER, 21st March, 1853. To the Association for the Exhibition of the Industry of all Nations, No. 53 Broadway, New York City: GENTLEMEN.—We observe this morning an article in thi " Scientific American," headed "The Crystal Palace," the perusal of which has led us to the following conclusions, viz., that if the article referred to be true, we do not consider ourselves bound to forward for exhibition the machine we intended for that purpose, it being so entirely different from what was represented to us by your agent when he visited our works. We remain most respectfully yours very truly, WOOD, LIGHT, & Co. [ANSWER] Association for the Exhibition of the In dustry of all Nations, Office No. 53 Broadway, New York, 22 March, 1853 : MESSRS. WOOD, LIGHT, & Co., Worcester, GENTLEMEN.—In answer to your letter of yesterday, I enclose you your application for space, which is considered as withdrawn.— The Committee was disposed to consider it as favorable as possible but in view of the very hasty conclusion at which you have arrivedt they have no reluctance in assigning the space relinquished by you to some other of the many worthy applicants who would oth erwise have been excluded. I have the ho nor to be your very obedient servant, WM. WHETTEN, Sec. P. S.—Mr. Joseph E. Holmes, who called upon you, desires to express his surprise that you should have paid so much attention to a publication not only not authorized by the as sociation but in manifest hostility to it, and grQWiBjg! out of a sentiment of personal re sentment, the source of which was marie pub lic some months since." [The above correspondence between Messrs. Wood, Light, & Co., and the Crystal Palace Association resulted, as most of our readers will understand, from an article which ap peared in number 27, headed " The Crystal Palace," wherein we commented upon the in justice of compelling exhibitors to pay for ad mission, which we learned it was their inten tion to do. The letter of the Association if construed strictly in accordance with the language held forth, fully confirms the impression expressed, in our article, because the firm did not wish to be considered as bound to forward a machine providing they were to be charged for admis sion to the Palace, and without hesitancy their application for space is returned to them, thus virtually acknowledging that the charge would be made. If, however, such is not their intention, then we say that the treatment of Messrs. Wood, Light, & Co., is beneath the dignity which ought to characterize the management of so important an enterprize, and must draw forth the condemnation of all high-minded men; why had not these gentlemen a right to enquire into a matter in which they were inte rested, and why should they not have been treated with common civility? The public must and will doubt the motive which prompts an association to acts so small and contemptible. The motives attributed to us in the post script are simply false and ridiculous, and would not elicit any remarks did we not wish to still further illustrate the spirit which pervades the management. We have repeat edly asserted that we hoped the exhibition would prove successful; we have no other wish at heart and never had after it was fully settled that it was to take place. We intended from the first and still intend to keep an eye upon the manner in which it is to be conducted, and we are bound as inde pendent journalists to express our disapproba tion of all attempts to disregard the rights and interests of contributors, who alone are able to render it an affair creditable to the na;ion. Our position is, and we hope always will be above the influence of place and pow-3r, and we intend that the public shall not suffer by our applause oi objects doubtful in iheir character. The Association did " not authorize" the publication of our remarks; well really this is juite cool, we are happy to inform the publit that the Scientific American is not the official arganofthe company, we are the organ for the people—the exhibitors—in whose welfare we feel much interest.
