On the other hand, a strong suggestion of similarity to these dishes is presented by some undecorated large stone lamps from Alaska, and by a class of pottery bowls with a human figure perched on the rim at one end from some of the Arkansas mounds, Mexico, and farther southward. (See Mason, J. A. A remarkable stone lamp from Alaska. The Museum Jour., Phila., 1928, 170-194.) _Copper mask._--Shortly before leaving Juneau I became acquainted with Mr. Robert Simpson, manager of the "Nugget" curio shop, and found in his possession a number of interesting specimens made in the past by the Tlingit Indians. An outstanding piece was an old copper mask, which was purchased for the National Museum. Mr. Simpson obtained it years ago from a native of Yakutat and stored it with native furs and other articles of value. It originally belonged to a shaman of the Yakutat tribe and was said to have been worn by him in sacrificial slave killings, the shaman with the mask representing some mythical being. It is an exceedingly good and rare piece of native workmanship. _Copper "shield."_--Another interesting article secured from Mr. Simpson is a large old shieldlike plate of beaten copper, decorated on one side with a characteristic Tlingit engraved design. Mr. Simpson, in a letter to Doctor Hough, dated June 26, 1926, says: "The shield, or to speak more correctly the copper plate--for it was not used as a shield--was the most valuable possession of the Tlingits. They were usually valued in slaves, this one, at the last known exchange, having been traded for three slaves. The possessor of four or five such plates was a man of the utmost wealth. Some claim that they got these copper plates from the early New England traders and others that they came from the Copper River. Either is possible. Lots of the Copper River nuggets were very large and flat and could have readily been hammered into plate form. I bought this in the village of Klawak on the west coast of Prince of Wales Island. I do not know of another one around here. All of the local elderly natives are familiar with its previous value, and when they have wandered into my shop to sell things they always made deep obeisance to this plate." _Talks._--While in Juneau the writer spoke before the Rotarians, who honored him with a lunch; and later, in the auditorium of the fine new high school, gave a public lecture on "The Peopling of America," etc. The object of these and the many subsequent talks in Alaska was, on the one hand, to reciprocate as far as possible the kindness and help received on all sides, and on the other to leave wholesome information and stimulus in things anthropological. The audience was invariably all that a lecturer could desire, and many were left everywhere eager for help and cooperation. The aid of some of these men, including prospectors, miners, settlers, engineers, foresters, and various officials, may some day prove of much value in the search for Alaskan antiquities.
