structure together with some life-like reproductions of plants. 
These form an important feature of the installations in Hall 
29 of the Department of Botany, where an appreciable be- 
ginning has been made toward the illustration, in this man- 
ner, of types of the entire plant kingdom on its main divi- 
sions. These models are produced in the Museum labora- 
tories. 
Case 13. Varieties of Quartz. The remarkable range of 
colors and forms of this mineral is illustrated. 
Case 14. Vertebrate and Invertebrate Fossils. Fossils 
from some of the more recent geologic periods are shown. 
They include a mounted skeleton of an extinct saber-tooth 
tiger, a fossil fish, and some beautifully preserved fossil am- 
monites, all from localities in the western United States. 
Case 15. American Horned Owl and Cottontail Rabbit. 
Our most rapacious bird surprised with its prey in the soli- 
tude of a winter landscape. 
Case 16. Decorative art of New Guinea, as exemplified 
by string bags, wood-carvings, and shell-work. 
Case 17. Metalliferous Minerals. Minerals which are 
compounds of some of the important metals, such as copper, 
lead, zinc, and iron, are displayed, the specimens chosen being 
especially those which are strongly colored, in order to illus- 
trate the colors often characteristic of these compounds. 
Case 18. American Red Fox. The common fox of east- 
ern North America is shown suddenly arrested in his hunting 
and listening with interest to the sound of quarreling mice 
under a log. 
Case 19. Birds of Paradise. Selected examples of the 
most curiously and gorgeously plumaged group of birds from 
the distant islands of New Guinea. 
Case 20. Basketry from the Indian tribes of California. 
Case 21. Buckskin costume, bags, and war bonnet from 
the Indian tribes of the Great Plains. 
Case 22. Blankets of the Navaho, Arizona and New 
Mexico. 
At the south end of the hall are a Chinese honorary 
gateway carved from teakwood and two pottery wine-jars of 
Roman times and also examples of the N. W. Harris Public 
School Extension cases.
