BULLETIN OF THE UNITED STATES FISH COMMISSION. 
near Paterson, N. J. (from the collection of Prof. D. S. Martin, of New York, where 
they had been since a short time after the discovery) ; and a small quantity of pearls 
taken from the altar of the Turner group of mounds, Little Miami Valley, Ohio (from 
the original find of Prof. Frederick W. Putnam, who obtained several bushels of 
them, resembling strikingly those found by Warren K. Moorehead). 
There was also a large collection of various species of Unios, from the small shells 
to the magnificent valves measuring nearly 8 inches in length, in a series in which one 
valve of each specimen is polished and the other in its natural state, to show the 
commercial possibilities of these shells. These were principally from the Sugar River, 
Wisconsin; others from Texas, Tennessee, and Kentucky. 
A glass jar contained a fine specimen of the fresh-water mussel Margaritana 
margaritifera , from the Botova River, in Bohemia, carefully prepared and injected, 
showing a pearl in place between the mantle and the shell (see plate n). 
A very interesting series of mounted fresh water pearls was shown from Wis- 
consin, Tennessee, Ohio, and Texas. Among these are some absolutely white, pink, 
and brown pearls. All those from Wisconsin are very fine, possessing a marvelous 
metallic luster. In the Mining Building, Bunde & Upmeyer, of Milwaukee, exhibited 
several hundred Unio pearls, some of them very fine, of the various colors found in 
the rivers of Wisconsin. 
The New York State exhibit, in the gallery of the Anthropological Building, con- 
tained a superb collection of Unios, beautifully mounted and well labeled, belonging 
to the State cabinet. This collection embraces those of the Rev. John Walton, Shelly 
G. Crump, C. Fj. Beecher, and others. In the south gallery, forming a portion of the 
exhibit of Professor Ward, of Rochester, were some magnificent specimens of Unios. 
Superb examples of Dipsas plicatus Lea, from Lake Riwa and from central China, 
containing pearl figures of Buddha, and fiat, pearl-like disks, produced by inserting 
between the mantle and the shell of the mollusk small tin-foil figures or disks, were 
shown in the folk-lore collection of G. F. Kunz and in the Ward collection in the 
south gallery (see pi. hi), both of which are now in the Field Columbian Museum. 
In the southeastern gallery of the Anthropological Building were about fifty 
specimens of Unios and mother of-pearl shells with one valve of each shell polished. 
One of the most interesting objects of pearl inlay was a small, round earthenware 
pot in the collection in the Cliff-dwellers’ exhibit, just west of the Anthropological 
Building. In this earthen pot irregular squares of Unio shell have been inlaid in 
hard clay in regular layers, the clay between the pieces of pearl being about the width 
of the pieces themselves, and producing the effect of mosaic. This is the only object 
so decorated that has ever been found. 
In the Swedish Building, Augusta Mollenberg, the royal court jeweler, exhibited 
twelve fresh water pearls, weighing from 4 to 10 grains each, eight mounted on a 
chalice and two on an ecclesiastical bowl. A Norwegian jeweler exhibited several 
dozen pearls, white and faintly pink, from Norwegian rivers. 
In the English section of the Manufactures Building, Edmund Johnson, jeweler 
royal of Ireland, exhibited several fresh-water pearls, weighing over 10 grains each, 
from Irish rivers, mounted in a brooch, in his collection of reproductions of Irish 
gold antiquities. 
In the Mexican section, in the Fisheries Building, from the district of Jederal, 
with a series of marine pearl shells from the west coast of Nuevo Leon, was another 
series of fresh water Unios, some measuring nearly 10 inches in length.
