As regards the style of ornament, it must be left to taste; but, as before promised, it will now be proper to introduce the remarks of Dr. Dibdin on the general effect of gilding and blind tooling, leaving the detail to be suggested to the mind of the gilder.

"First, let your books be well and evenly lettered, and let a tolerable portion of ornament be seen upon the backs of them. I love what is called an _overcharged back_, At first the appearance may be flaunting and garish; but time, which mellows down book ornaments as well as human countenances, will quickly obviate this inconvenience; and about a twelvemonth, or six months added to the said twelvemonth, will work miracles upon the appearance of your book. Do not be meagre of your ornaments on the back, and never suffer _blind tooling_ wholly to pervade a folio or quarto; for, by so doing, you convert what should look like a _book_ into a piece of mahogany furniture.

"In large libraries there should not be too much blind tooling or too great a want of gilt. No doubt the ornament should be as appropriate as possible to the book. One could not endure gingerbread-gilt _Bibles_ and _Prayer-Books_, or _Chronicles_ or _Dictionaries_, or other books of reference. Let these have a subdued decoration on their backs; bands only full-gilt, or a running edge-tool in the centres of them, with small ornaments between the bands.

"I would recommend the lettering of a volume to be as _full_ as possible; yet sententiousness must sometimes be adopted. The lines should be straight, and the letters of one and the same form or character within the line; yet the name of the author may be executed a size larger than that of the date or place of its execution, and the lettering may be between the top and bottom bands, or it may occupy the spaces between three bands, or even more. Re-letter old books perpendicularly, as was the custom. In all fresh bindings, however, prefer horizontal to perpendicular lettering."[A]

[Footnote A: We sometimes fear that Dr. Dibden's commendation of an overcharged back has produced a bad effect. It should be borne in mind that, when the doctor wrote, calf was the prevailing material employed in binding, and that of a light colour.]
