'Without taking into consideration the enormous difference between carping at the deficiencies, and condemning the faults, of others, and that of _avoiding faults_ and _supplying deficiencies_, and losing sight, also, of the important truism, that knowledge derived from experience even, in order to subserve any useful purpose, either in authorship or in its application to business, must be drawn from _successful_ experience, many of our book-mongers seem to take it for granted, that to be able to raise plausible objections to the books that have fallen in their way, and to profess experience in teaching a particular science, constitute the grand climacteric of all that is requisite in order to form a successful _writer_ upon that science. But it is not the man who has merely _taught_, or who has taught _long_, or who is able to point out _defects_ in authors, that is capable of enlightening the world in the respective sciences which have engaged his attention; but the man who has taught _well_. It is the man of genius and enterprise; he who has brought to the task of his calling uncommon powers of discrimination, and a sound judgment, and whose ambition has led him not to rest satisfied with following the tedious routine of his predecessors, but _to strike out a new and a better track_, or at least to render smoother and brighter the path long trodden. It is to such men, and such only, that we are indebted for all our great improvements in the construction of elementary works for schools and private learners.' S. KIRKHAM. _New-York, July 25, 1837._ FOOTNOTES: [7] A short time since, Goold Brown stated to the writer, that 'in eleven years he had received but just nine hundred dollars for copy-right.' [8] I can name the time and place. It occurred at the funeral of Aaron Ely. * * * * * NEWSPAPORIAL.--Our readers are not ignorant of the high estimate which we place upon the 'NEW-YORKER' weekly journal. For industry, talent, interest, and general usefulness, we scarcely know its superior. In a recent eloquent appeal to the justice of its numerous delinquent subscribers, it announces that hereafter, owing to the pressure of the times, it can only be afforded at three dollars per annum for the folio, and four dollars for the quarto edition; at the same time giving notice, that it will credit all payments, until the first of November, at the original price of two and three dollars. THE SUNDAY MORNING NEWS, already well established in reputation, and very widely circulated, has received a valuable addition to its attractions, in the accession of JOHN HOWARD PAYNE, ESQ., formerly of the 'Ladies' Companion,' and Mr. JOHN JAY ADAMS, to its editorial department.
