(We had not intended to say any thing on the subject of the "Eureka" in this number, nor until the second number of the work should have been issued: but finding that a great degree of dissatisfaction exists in the minds even of those who are represented in that paper to be the supporters and conductors thereof; and having received an implied request for the insertion of the following communication, we would not refuse it, although we doubt whether the Eureka will ever reach its third number, whether its contents are subjected to public criticism or not.) _Mr. Editor:_ I had a little curiosity to hear what the press said of this periodical; but as yet I have not seen any notice, except the brief one in your columns. As a general rule, it is inexpedient for an association to publish a periodical. Instead of being an expression of the society, it almost unavoidably becomes the organ of a clique, and renders the patronage of an otherwise liberal organization subservient to private interest. In the columns of the "N. York Farmer" was first advocated the formation of the N. Y. State Agricultural Society. Among the first acts of this society was the issuing of an agricultural paper at _twenty-five cents_ per annum. This was scattered over the whole country to the injury of those who had been pioneers in publishing agricultural papers. The Society could not sustain it without loss. It was sold to an individual on condition that he would publish the proceedings of the Society. The price was quadrupled. It was soon found that a periodical having a general circulation, could not devote much space to a local society, however noble and prosperous. Necessity led to the columns of the daily press, and to the issuing of a yearly volume of Transactions. This will be the result of every prosperous association. If the proceedings are worth publishing, the press will spread them over the whole face of the civilized world. A collection of the most important and well-digested papers in a yearly volume, is more in accordance with the dignity and usefulness of a national association. Besides the injustice done to other periodicals previously in existence, the association adds nothing to its reputation by the undertaking. There are three or four individuals at the American Institute who have a hankering for the control of a paper. It is very easy to see that the publishing of a weekly paper by the Institute would be a suicidal act. All the Institute has to do is to make its proceedings interesting, and the widest publicity will be given as a matter of course.
