kind. Some of this is coarse and rough, and in this case always more
than ordinarily thick; but the larger portion has the surface smooth and
often polished. The color varies from the natural dull leaden hue of the
clay, to a bright brick red, the latter largely predominating.

2. _The brown ware_, or that which shows an admixture of mica. This,
although uniformly without color decorations, is occasionally marked
with impressed figures and lines. Although inferior in quality, being
coarse and fragile, it presents more symmetrical though less varied
forms than are usually found in the preceding group. The influence of
contact with the European races is here very apparent, as, for example,
in the true pitcher and other common utensils and an apparent attempt at
glazing.

3. _The black ware_ which is without ornamentation. This variety in
quality and character is precisely like the polished red of the first
group; but is slightly in advance of that in regard to finish, and
perhaps, as heretofore remarked, may be classed as lustrous, while the
red may be classed as semi-lustrous. The paste of which this black ware
is formed appears to have been better prepared than that of the
preceding varieties, and is the hardest and firmest in the collection.

4. _The cream-white pottery decorated in colors_. This extensive group,
which includes fully two-thirds of the entire collection, embraces
almost every known form of earthenware manufactured by the tribes from
whom it was obtained. The paste of which it is formed is similar in
character to that of the black ware. When broken the fracture shows very
distinctly the effect of burning, the interior being of the natural
leaden color, shading off to a dull grayish white as it approaches the
outer surface. The opaque or creamy-white color of the surface is
