as witness the great connoisseurs of the turn of the century—J. P. Morgan, Benjamin Altman, Heber R. Bishop, T. B. Walker—and the tradition continues with men like Avery Brundage, whose collection of Oriental art is now housed at the de Young Museum in San Francisco.
The author has traveled throughout the United States in search of jade, and has purposely selected examples from U.S. museums only, as most of these collections have received little attention recently. The pieces herein are but a sampling of the rich treasure in American galleries.
Quite a few of the jade carvings in this volume are not on exhibition at present. It is deplorable how much jade and other fine art is hidden away in museum storerooms! There are, of course, some pieces which are so close in style to that which is already on display that it would be superfluous to exhibit them. I suggest that perhaps these articles could be loaned to other museums whose collections are not as adequately endowed. Again, there are jades which do not meet museum standards of quality. Possibly these pieces could be lent to schools for study purposes. In any case, I hereby make an urgent plea for a clean sweep so that jades and other objets d'art, as well, will once again reflect the light of day and we will all have the opportunity to reap their aesthetic rewards.

Introduction
Location of Jade Rough Material
There are distinctly two materials known as jade in the Western world—nephrite and jadeite. The former is found in the mountains and river beds of Eastern Turke-stan (near Khotan and Yarkand). It is this nephrite material which was familiar to the ancient Chinese as well as later generations.
Nephrite is also found near Lake Baikal in Siberia. It is uncertain when the Chinese first imported this material, but Hansford suggests that trade began after 1850 [19, pp. 46-48]. As many pieces made of this material are typically 18th century, the question remains open.
Jadeite was originally discovered in the tributaries and valleys of the Uru River near Mogaung, Burma. From the late 19th century on, however, the major source has been the Tawmaw Plateau. While there may have been some jadeite brought to China at an earlier time, there is no conclusive record of this until the latter part of the 18th century, during the reign of Emperor Ch'ien-lung [21, p. 44].
In recent years, small deposits of nephrite' and jadeite (the latter reputedly of a similar color quality to Burmese material) have been found on Honshu island, Japan (in Kotaki and Omi); these deposits may have been the original source of material for the numerous jadeite beads excavated from early Japanese Jomon (prehistoric) tombs. There is no evidence, however, that this stone was ever exported to the Chinese mainland. We conclude, then, that the jadeite known to the Chinese was of Burmese origin [36; 52].
The preceding simply clarifies a few points which are sometimes misunderstood, and leads us to perhaps the most astonishing fact of all. Despite varying accounts to the contrary, no definite proof has been established that either nephrite or jadeite was ever quarried in China proper! Some authorities have translated references to jade from Chinese classical writings, but it has been pointed out that the word yü or its calligraphic equivalent also refers to other minerals and sometimes
