National, Series of Text Books. In another column will be found ai advertisement of the National Series of Text Books, published and for sale by A. S. Barnes & Co., William Street, New Y ork. The Messrs. Barnes are largely engaged in the publication of school books, having one of the most extensive establishments in New York, with facilities for meeting any demand which may be made for their works. Of the merits of the National Series of Readers, we are not prepared to speak personally. They have been adopted for the common schools of this Territory, Terri-tory, by the Territorial and County Superintendents, who are authorized by law to make such selection. We have therefore no alternative but to accept their decision, believing that in the change they have been actuated ly a desire to subserve the cause of education. We bave been opposed to a change in text books, because we know of no good reason why such change should be made, and there are many reasons why it should not ; among others, the expense it will entail en-tail on the community at a time when it can illy afford it. Inasmuch, however, how-ever, ai a change has been deeided on, we hope the board of superintendents have adopted the best books at their command, so that another change may not be necessary in a few years. Without With-out giving any decision for or against the Keaders of the National Series, we believe the geographies, the ecientiric text book? and the German series are very generally commended. We have every confidence in the business reliability relia-bility of Messrs. Barnes it Co., aud doubt not that our merchants aud school trustees who order from them will find all their arrangements satisfactory.
