2.—Every line should be boldly, clearly, and elegantly drawn.

3.—Harmony of design, balance of proportions, sympathetic formation of the various parts, demand vigilant maintenance.

4.—Originality of design, with every part having an intimate relationship, an indivisible connection with every other part, is indispensable.

In the execution of a relief scroll, or any style of scroll for that matter, it is a factor of the first importance that the surface be smooth and thoroughly dry.

A great deal of business vehicle scrolling is necessarily done upon the color-and-varnish coat or upon clear rubbing varnish. To prevent the gold leaf (in case gold is used) from adhering to the varnish coat, various expedients have been resorted to, among which the whiting pounce figures as the most effective and the easiest applied. Other recipes include rubbing the surface with a thin solution of starch and water, or glazing it with the white of an egg, or washing it with whiting and water, or applying a thin film of potato starch upon it. Good gilding size is very essential in the art of scrolling. The light and easy whirls of the pencil cannot be done with a size unsuited for the purpose. Moreover, shop requirements have to be met, and they may impose a limit of two hours in which the size must dry today, and tomorrow that limit may be extended to four hours or even longer, and perhaps—although in these days of ocean racers and Black Diamond flyers this may be a remote possibility—the size will be expected to hold over night, after its application, before being gilded.

Quick size.—Gold size japan, 5 parts; fat oil, 1 part. With a dash of japan ground chrome yellow, this size will dry to safely leaf over in 1/2 hour.

Medium quick size.—Gold size japan, 4 parts; fat oil, 2 parts.
