§ If each jury were to explain concisely the means employed by them to examine the qualities of each class of objects submitted to them, much valuable information would result. A collection of these rules for the judgment or verification of articles, if reduced into order, and published in a small compass, by a competent person, at the close of the Exposition, would be invaluable to the public. The result would be beneficial to all _honest_ tradesmen, and injurious only to the _fraudulent_. Such means when put into the hands of the public would soon enable it to distinguish the genuine from the sophisticated articles, and to select those which in point of excellence and durability are best suited to the means or wants of the purchaser.[10] The increased knowledge of the public would be felt by the retail dealers, and would make them more anxious to obtain excellent and durable goods from the manufacturer. § Several of the papers issued by the Commission bear honourable testimony to the sagacity of those who composed them. They treat the persons addressed as reasoning men, explaining to them the results contemplated: thus whilst offering their own most strenuous exertions, they admit that these would scarcely prove effective without the co-operation of the public in a plan devised for the common advantage of all. In former days had there been water-fowl in our parks, some such notice as this would have been placarded:— “Whoever throws stones at, or frightens these birds, shall be prosecuted with the utmost severity of the law.” In the present day we read the much more effective address, “These birds are recommended to the protection of the public.” However ragged the coat of the passer-by, his feelings not his fears are addressed, and his pride is gratified by being appointed as it were a temporary trustee for the safety of his feathered friends. The advantage of acting upon this principle is not confined merely to its direct efficiency for its purpose. A still more important benefit remains latent, one which never ought to be lost sight of in the enactment or the administration of laws. _It enlists public opinion in favour of law and of order._[11] Thus aiding the prevention, the detection, and the punishment of offenders, it renders the interference of the police far less necessary, and when called for, more effective. § This principle might perhaps be applied with advantage to the admission under regulations of certain classes of _skilled_ workmen by means of tickets, for a limited number of days. Most effective assistance might be rendered both to the police and to the attendants at the Exposition by the following plan:—Allow a certain number of persons, in whom the executive can repose confidence,—generally master manufacturers or employers,—the privilege of recommending a small number of their best and most regular workmen or assistants, to whom should be granted tickets of admission, subject to the following conditions:—
