[Illustration: Fig. 87.--Blue-and-white Chinese, “Hawthorn” Pattern. (S. P. Avery Coll., N. Y. Metrop. Museum.)] When the Chinese artist condescends to adopt a regular pattern, his attention is directed to relieving the monotony of repetition by diversity of detail. In the vase (Fig. 86) there are at least six distinct styles of edging, and a slight change in the arrangement of the same pattern on the body and neck gives all the variety of two distinct designs. A well-known but rare pattern is that called Hawthorn (Fig. 87) by Europeans, on the _lucus a non lucendo_ principle, since the so-called “hawthorn” is the blossom of certain fruit-trees better known to the Celestials. In this the blue is the ground-color, and in it the decoration, consisting of sprigs of bud and blossom, is reserved. The ground is varied with dark blue lines, as if to simulate crackle, and the sections are shaded so as to have the appearance of overlapping each other. The irregular lines and changing tints not only relieve the ground of monotony, but enrich the general effect, and give the blue additional depth and transparency. The illustration gives a good idea of the freedom with which the spray is disposed, and the good taste with which its arrangement is adapted to the shape of the vase. The decoration is generally applied to vases and pots of the shape given above. Further examples are in the collections of Mr. Robert Hoe, Jr., and Mr. W. L. Andrews. There are also many smaller pieces, such as plates, narrow cylindrical beakers, and others, upon which it may be seen. These are represented in the collections of Mr. Francis Robinson and Mr. W. T. Walters. In such pieces as those last mentioned the ground is less broken up by lines, and in some cases the white is reserved in a ground of unbroken pale blue. In the second specimen (Fig. 88) the white blossom is used with a more sparing hand than in the others, and the eye more readily appreciates the wonderfully beautiful shading of the overlapping sections. The unevenness of surface is also more perceptible to the touch, and, to use a familiar illustration, resembles the overlapping of slates upon a roof.
