These are the two principles which the present compiler has had constantly in mind. Yet the second principle has been violated more than once, since, in a collection such as this, one must cut one's coat according to the cloth; or, rather, one must make sure that one is decently covered, though the covering may here and there be somewhat inferior in quality. So it has been necessary, in order to keep the thread of history unbroken, to admit some strands anything but silken; and if the choice has sometimes been of ills, rather than of goods, the compiler can only hope that he chose wisely. The most difficult and trying portion of his task has been, not to get his material together, but to compress it into reasonable limits. Especially in the colonial period was the temptation great to include more early American verse. Peter Folger's "A Looking-Glass for the Times," Benjamin Tompson's "New England's Crisis," Michael Wigglesworth's "God's Controversy with New England," the "Sot-Weed Factor," and many others, which it is recalling an old sorrow to name here, were excluded only after long and bitter debate. No doubt other exclusions will be noticed by nearly every reader of the volume--and it may interest him to know that the material gathered together would have made four such books as this. The thread of narrative upon which the poems have been strung together has been made as slight as possible, just strong enough to carry the reader understandingly from one poem to the next. The notes, too, have been limited to the explanation of such allusions as are not likely to be found in the ordinary works of reference, with here and there an account of the circumstances which caused the lines to be written, or an indication of source, where the source is unusual. Every available source has been drawn upon--the works of all the better known and many of the minor American and English poets, anthologies, newspaper collections, magazines, collections of Americana and especially of broadsides--in a word, American and English poetry generally. In this connection, the compiler wishes to make grateful acknowledgment of the assistance he has received on every hand, especially from Mr. Herbert Putnam and Miss Margaret McGuffey, of the Library of Congress; Mr. N. D. C. Hodges, librarian of the Cincinnati, Ohio, Public Library; Mr. C. B. Galbreath, librarian of the Ohio State Library; Mr. Charles F. Lummis, librarian of the Los Angeles, California, Public Library; Dr. Edward Everett Hale, Mr. William Henry Venable, Mr. Isaac R. Pennypacker, Mr. Arthur Guiterman, and Mr. Wallace Rice. He might add that it is a matter of deep personal gratification to him that in no instance has any author refused to permit the use of his work in this collection. On the contrary, many of them have been most helpful in suggestions.
