In fact the danger of all collectors is this alluring temptation which besets other people in other ways. Many people prefer the exception to the rule, the imperfect sport to the commonplace type. If so, this discursive chatter is not wholly irrelevant, since it preludes an apology for including certain references to work distinctly below the level of the best, which, by its accidental position in volumes where the best occurs, can hardly be ignored completely. Another point of conscience arises which each must decide for himself. Supposing that the collection of wood-engravings of the sixties assumes the proportion of a craze, must the collector retain intact a whole set of an illustrated periodical for the sake of a few dozen pictures within it, or if he decides to tear them out, will he not be imitating the execrable John Bagford, who destroyed twenty-five thousand volumes for the sake of their title-pages? Must he mutilate a Tennyson's _Poems_ (Moxon, 1857) or _The Music-master_, or many of Dalziels' gift-books, for the sake of arranging his specimens in orderly fashion? The dilemma is a very real one. Even if one decides to keep volumes entire, the sets of magazines are so bulky, and in some cases contain such a small proportion of valuable work, that a collector cannot find space for more than a few of them. Possibly a fairly representative collection might be derived entirely from the back-numbers of periodicals, if any huge stores have yet survived the journey to the paper-mill or the flames; the one or the other being the ultimate fate of every magazine or periodical that is not duly bound before it has lost its high estate, as 'a complete set,' and become mere odd numbers or waste-paper. So far the question of cost has not been raised, nor at present need it frighten the most economic. Taking all the subjects referred to in this book, with perhaps one or two exceptions (Allingham's _Music-master_, 1855, for instance), I doubt if a penny a piece for all the illustrations in the various volumes (counting the undesirable as well as the worthy specimens) would not be far above the market-price of the whole. But the penny each, like the old story of the horse-shoes, although not in this case governed by geometrical progression, would mount up to a big total. Yet, even if you purchase the books at a fair price, the best contain so many good illustrations, that the cost of each is brought down to a trifle.
