The difficulties attending such inquiries as arise out of matters so trivial as an old ballad, are curiously illustrated by the answers already printed respecting the "wooing frog." In the first place, it was attributed to times within living memory; then shown to exceed that period, and supposed to be very old,--even as old as the Commonwealth, or, perhaps, as the Reformation. This is objected to, from "the style and wording of the song being evidently of a much later period than the age of Henry VIII.;" and Buckingham's "mad" scheme of taking Charles into Spain to woo the infanta is substituted. This is enforced by the "burden of the song;" whilst another correspondent considers this "chorus" to be an old one, analogous to "Down derry down:"--that is, M. denies the force of MR. MAHONY's explanation altogether! (Why MR. MAHONY calls a person in his "sixth decade" a "sexagenarian" he best knows. Such is certainly not the ordinary meaning of the term he uses. His pun is good, however.) Then comes the HERMIT OF HOLYPORT, with a very decisive proof that neither in the time of James I., nor of the Commonwealth, could it have originated. His transcript from Mr. Collier's _Extracts_ carries it undeniably back to the middle of the reign of Elizabeth. Of course, it is interesting to find intermediate versions or variations of the ballad, and even the adaptation of its framework to other ballads of recent times, such as "Heigho! says Kemble,"--one of the Drury Lane "O.P. Row" ballads (_Rejected Addresses_, last ed., or Cunningham's _London_). Why the conjecture respecting Henry VIII. is so contemptuously thrown aside as a "fancy," I do not see. A _fancy_ is a dogma taken up without proof, and in the teeth of obvious probability,--tenaciously adhered to, and all investigation eschewed. This at least is the ordinary signification of the term, in relation to the search after truth. How far my own conjecture, or the mode of putting it, fulfills these conditions, it is not necessary for me to discuss: but I hope the usefulness and interest of the "NOTES AND QUERIES" will not be marred by any discourtesy of one correspondent towards another. At the same time, the HERMIT OF HOLYPORT has done the most essential service to this inquiry by his extract from Mr. Collier, as the question is thereby inclosed within exceedingly narrow limits. But if the ballad do not refer to Henry VIII., to whom can it be referred with greater probability? It is too much to assume that all the poetry, wit, and talent of the Tudor times were confined to the partizans of the Tudor cause, religious or political. We _know_, indeed, the contrary. But for his communication, too, the singular coincidence of two such characteristic words of the song in the "Poley Frog" (in the same number of the "NOTES AND QUERIES") might have given rise to another conjecture: but the _date_ excludes its further consideration.
