The second manner of faking in decorating the cover of a book is to use some old iron stamps for the impress on the leather of the binding. Some of these old implements that have escaped destruction are now used to advantage, especially to stamp decorative coats of arms on imitation antique bindings, so that the buyer should think the books have come straight from the former library of a nobleman. The faker has used this trick successfully with Americans particularly. In this way the stamps of the _Sacré de Louis XV_, which are, apparently, still in existence, have been used as a decoy on fine bindings, as well as that of the Rohan-Chabot family coat of arms perpetuating the supposition that books belonging to that illustrious family are still on the market. The third method is called in French _rembotage_ and consists, as we have said, of transferring covers from one book to another. There are some good editions that have lost their covers and some worthless books with fine bindings--fakery repairs this injustice of fate by transferring the good binding to the more meritorious book, a simple act of justice invariably rewarded in the world of fakery by the large sum that can be asked for the edition thus treated. There are naturally many ways to discover the bindings that have in one way or other received the paternal and not at all disinterested caress of the faker, but the best and safest way--shall we ever tire of repeating it--is to train one’s eye to that helpful synthesis of judgment called experience. Newly coloured and patinated leather does not stand rubbing with a damp cloth like the old does, modern gilding and modern stamping imitating antique designs are heavier and less clean cut as well as not so rich--qualities best understood by comparing modern work with the old, for although the differences are slight they are, nevertheless, plain to the experienced eye accustomed to comparing old and new. Even _rembotage_, the most difficult to detect, may be found out by examining the way one part is joined to the other, the peculiarities of the work, etc. All that can be said, however, to put the neophyte on his guard who may imagine that hints from books or special works on the subject are sufficient to assist him, is: Go slow, and if you are really anxious to have a good collection and prepared to pay good prices, in the beginning ask the man who knows for his help--_Experto crede_.
