We make it a rule to keep our readers well posted up in all that concerns their interest, and therefore feel bound, by virtue of our position as the Advocate of Inventors and Mechanics in general, to watch with a jealous eye the proceedings of the above Association. Notwithstanding all the fanfonarade exhibited by its officials, in boasting that they have received five times more applications than they have space to afford, we doubt the fact very much. It appears like a storekeepers puff to get rid of his goods, which are so exceedingly cheap that all the world is disputing who shall give his money for them. However, the time for making applications is now gone by, and no others than the lucky individuals who made their applications in time are to be honored with the title and the privileges of exhibitors. Let us examine, however, what these privileges are, and then perhaps the too tardy applicants, who number to the successful exhibitors five to one, according to the statistics of the Crystal Palace office in Broadway, will not be ready to die of despair. The New York Exhibition of the Industry of all Nations ismodelled, as we are informed, on that held in London, the year before last, and really, if we take into account the self-assumption and arrogance ol its jacks in office, it is on a grasder scale. The future exhibitors have put their heads into a noose out of which, it strikes us forcibly, they will not be able to draw them without paying for the privilege. The orders of the Association of the Crystal Palace are as peremptory as those of the Autocrat of Russia, and the obedience of the exhibitors expected to be as prompt as that of his sens. The articles intended for exhibition must be on the spot by the first week in April, but the Company give no guarantee that there will be a roof over the building at that time to protect them from the weather. The quality of space required was to be specified in the application, but no satisfaction is afforded as to where the articles will be placed, of course the favored few or many will not have theirs in the back ground. And, as a climax, the exhibitors will have to pay for admission, it being very friendly and patronizingly observed, that it will be cheaper to take a season ticket, by this means an exhibitor, who may require to go inside the building every day, at least once and perhaps several times, will be able to do so at a cheaper rate—just as cheap ?.s the public. This is a provident foresight, for which the Association ought to vote their Directors at least a leather medal, to be distributed with the other prizes, as by this means, if from nothing else, they will draw some interest for their shares from the exhibitors, on whose tafents and industry they are at the same time dependent for their success. Now this is really too bad, and we do sincerely hope that the exhibitors will protest, en masse, against this barefaced injustice ; its is but fair that they should have free access at all times to the interior of the building, or else of what benefit will it be to them to entrust their property for exhibition. To suppose that an individual is to do so, and yet not to have free access to the building when it is open, is a monstrous absurdity, and if known at a seasonable time, instead of having five times too many applications, the Association would not have had one, that is, not from a manufacturer or merhanic of any respectability. There may be a class of exhibitors who will have no objection to pay lor admission, speculating upon the sale ol some trumpery article, but the majority of bona fide exhibitors, we are quite sure, will object to any such tax, which ought to have been publicly stated at the time that the Company put out their original advertisement. We therefore advise the Directors to retract this demand, or if they have not publicly made it, to abstain from doing so, for as soon as it is generally known they may depend upon it that such an imposition will be protested against. The majority of the exhibitors are not aware of their intention to do soand it is but right that it should be known by them ; it is however certain that such will be the case, and therefore we look upon the evasive conduct of the managers of the Association in not giving a decided answer to inquiries upon this point as mean and disgraceful in the extreme. If the exhibitors are to be fleeced, as is evidently intended, let them know it, and then they will be prepared how to act, but at present nearly all are ignorant of this attempt upon their pockets. There are some other matters connected with this enterprise on which we wish to speak, but we will deferit to another time ; the proceedings of the Association as far as the interests of inventors and others are concerned, we shall continue to closely watch.
