S. A. 1924 c+ipr y exhibits illustrat- ing the ethnology of Africa (Cases 1-22), in particular the art of ancient Benin. Exhibits in the center of the hall illus- trate the culture of India (shields and weapons, ancient brasses, and bidri ware, musical instruments). Special attention is called to the ancient stone sculpture from India, which includes both the early Gandhara period (first and second centuries A.D.) and the later and Jaina art. Further, there are exhibits from East Siberia, Korea (with a notable display of official and court costumes), Formosa, and Java (represented by good examples of batik cloth). The north portion of the hall con- tains collections from Tibet (Cases 44-80), likewise secured by the Black stone Expedition of 1908-10. Weaving and textiles, clothing in a series of costumed figures, and jewelry are fully represented. Images, paintings, sculpture^ niusiehl instruments, and other objects used in worship in the Lama temples are displayed in twelve cases. Hall 23 (at north end of East Gallery) contains the Edward E. Ayer collection of pewter comprising several hundred objects of pewter of European and Chinese origin. Hall 30: Frank W. Gunsaulus Hall (southeast corner, sec- ond floor): Japan. In the smaller room are displayed Japa- nese prints (Surimono, cards of greeting for special occasions). The larger room contains a collection of sword mounts (pre- sented by Dr. Gunsaulus), armor and weapons, costumes of women, Buddhism illustrated by wood carvings, N5 masks, ivory carvings, and musical instruments. A set of dolls used for the Girls, Festival occupies the center of this room. On the walls are shown a wood-cut reproduction of a famous landscape by Sesshu, a large tapestry representing the dedica- tion of the temples of Nikko, and a painted screen of the Tosa school (presented by Dr. Gunsaulus). Ground Floor Hall J : Archaeology of Egypt. There are twenty-two cases containing coffins and mummies of men and animals, ranging from the pre-dynastic to the Eoman period. Twelve cases are devoted to exhibits of pottery, marble and alabaster vases, bronze vessels, figures of deities in bronze and stone, bronze objects for temple use, ushebti figures, jewelry, charms, models of granaries, bricks, mortuary offerings of schist, Coptic objects in bronze and iron, portrait statues, and tomb tablets. Two cases contain Canopic jars, boxes, biers, stools, and coffin covers of stone and wood. In the southwest portion of the hall is a mortuary boat of Sesostris III, from his pyramid at 12 Dashur. There are also shown three sarcophagi, one of the Saitic period, one of the thirtieth dynasty (fourth century B.C.), and another of the Roman period (30 B.C. or later). In the northwest portion of the hall are erected two Mastaba tombs, one of User-neter from the Necropolis of Sakkara (Vth dynasty, 2700 *B.C.) and another of a nobleman, Unis-ankh, from the cemetery of Memphis, Sakkara (early Vlth dynasty, 2600 B.C.). Hall I: Dramatic Performances of the Orient, arranged in geographical order. Proceeding from west to east, the exhibits are as follows: — 1. Chinese religious drama, showing the ten purgatories (Cases 1-4). 2. The Lion Dance, China (Case 5). 3. Chinese masks from an imperial play, illustrating gods and heroes of the Taoist religion (Cases 6-7). 4. Chinese shadow-play figures (Cases 8-9). 5. Masks used in Tibetan mystery-plays (Cases 10-12). 6. Masked figures of a Tibetan mystery-play (Cases 13- 17). 7. Puppets or marionettes from Java and orchestra ac- companying performances (Cases 18-21). 8. Masks, actors’ head-dresses, and actors’ costumes, Java (Cases 22-24). 9. Singhalese masks, Ceylon (Cases 25-28). DEPARTMENT OF BOTANY Halls 25-29, Second Floor The installations in the halls of this department are de- signed to illustrate, as fully as possible, the forms of plant life and the products yielded by vegetation for the use of man. Hall 25: Plant Economics. — The north side of this hall is devoted to a display of the botany and economic products of the Palms, with some cases of Bamboo. The south side of the hall is occupied by food products of vegetable origin, the cereal grasses and small grains, corn and its products, starches, sugars, vegetable oils and fats, tea, coffee, spices, etc. Hall 26: Charles F. Millspaugh Hall. North American Trees. —The cases in this hall present monographic displays of the trees of North America. They show: first the trunks in size ratio throughout; the tree in summer and winter; the wood in plain, quartered and figured boards; a branch in leaf and flower; a map, colored to show the area of distribution; and 13 a descriptive label giving such other information of each species as the specimens themselves fail to convey. Hall 27: Foreign Woods. — The cases in this hall are grouped geographically and contain specimens of the woods and timbers of Russia, Korea, Japan, Formosa, Australia, Philippines, Ceylon, India, Johore, Jamaica, Trinidad and various countries of Central and South America. The speci- mens are so prepared as to give as full an idea as possible of their character and grain. The Japanese series is the most valuable and comprehensive ever brought together. Hall 28: Plant Economics. — On the north side of this hall are displayed various kinds of fibre yielding plants, such as cotton, flax, hemp, jute, and their products. On the south side of the hall are shown varnish gums, lacquers and lac, wood distillation products, rosin and turpentining methods, paper pulp products, cork, tanning materials, dyewoods and a variety of crude drugs. Hall 29: Hall of Plant Life. — The exhibits in this hall are designed to furnish a general view of the range of plant life. Beginning at the northeast corner of the hall the lowest order of plants, the Bacteria, is followed by the Algae, Fungi, Mosses and other non-flowering plants, next are the Conifers and then the flowering plants. The latter occupy most of the hall. Among especially noteworthy exhibits are the flowering and fruiting top of a Coconut Palm, at one end of the hall and at the other, the flower-bearing trunk of the curious Cannon-ball tree, restored to lifelike condition. The hall is far from complete but new exhibits are continually added. Third Floor: The Herbaria. — Three large collections, com- prising over 500,000 specimens of mounted plants, are installed in rooms over Hall 25. These are accessible to those persons specially interested in botany. DEPARTMENT OF GEOLOGY Halls 34-38, Second Floor Hall 34: Minerals, Crystals, Meteorites, Physical Geology* — The east half of the hall is occupied by the mineral collection, in which the minerals are arranged in the customary order. The collection begins at the east end of the hall with the native elements and ends with the hydrocarbons. The William J. Chalmers crystal collection follows. This collection illus- trates, by means of carefully selected mineral specimens, the systems according to which minerals crystallize, and the vary- ing development of crystal form in each system. Several types of twin crystals, and the laws of crystal grouping are illus- trated, as well as various other features of crystal growth, such as zone structure, inclusions and phantoms. 14 An extensive meteorite collection occupies the larger por- tion of the western half of the hall. This collection contains specimens of the great majority of the known meteorites, arranged according to the established classification. Of 850 known falls, 676 are represented here. Many of the specimens are in the form of polished and etched slabs, which display the interesting interior structure of meteorites. The exterior fea- tures peculiar to these bodies are shown by numerous complete and unbroken specimens. Four of these, installed in separate cases, range in weight from 466 pounds to nearly two tons. The west end of the hall is occupied by that part of the collection of physical geology which illustrates glacial phenom- ena, rock weathering and concretions. Two large rock slabs, displayed on bases in alcoves near by, show the effects, in unusual perfection, of glacial planing and grooving of rock. The rest of the physical geology collection is installed in Hall 35. Hall 35: Physical Geology, Rocks, Relief Maps. — The collec- tions at the east end of this hall are a continuation of those in the west end of Hall 34. The more important groups illustrate volcanic products, dendrites, tufas, veins and vein structure, faults, folds, joints and cave formations. Contorted, ropy lava surfaces from Vesuvius and volcanic bombs from France and New Zealand are conspicuous among the volcanic specimens. There are also shown many examples of such oft-mentioned sub- stances as volcanic ash, lapilli and mud. Many of the dendrites, which are fern and flower-like forms deposited by water seeping through cracks in rocks, are objects of exceeding delicacy and beauty. In the case illustrating rock structure, large specimens illustrating slaty cleavage are worthy of attention. Welsh quarrymen have split these great pieces of slate along the cleavage into many thin leaves. In another case are large specimens of ripplemarked sandstone, which display large surfaces ripplemarked by wave action exactly as the sands of lake and sea shores of the present day are scored. A block of lodestone is placed on a pedestal against the wall. With it is a compass so arranged that it may be moved around the specimen to show that the compass needle will always point to the lodestone. Cave products occupy one case. While these consist largely of limestone stalactites and stalagmites, other cave products, such as floor deposits and gypsum rosettes, are also represented. Caves of an unusual type in Utah ornamented with huge, transparent, gypsum crystals instead of the usual limestone stalactites are illustrated by a number of crystals from such a cave which have been so installed as to repro- duce its appearance. A large fulgurite or lightning tube over eight feet long which was formed when lightning struck into an Indiana sand dune occupies a case by itself. In an adjoin- ing case smaller fulgurites from other localities show the effect of lightning on both sand and rock. In one case in this hall a model of the Natural Bridge of Virginia is shown. Be- 15 sides being a faithful reproduction of the bridge in natural colors, with the vegetation and other features reproduced, it illustrates a number of features of rock structure which occur on too large a scale to be satisfactorily shown by small speci- mens. The western half and somewhat more of the hall is occu- pied by a collection of relief maps, which show the topography of selected portions of the earth’s surface. Some of these are representations of well known scenic areas. Others illustrate the topography of States and other political divisions. Por- tions of the earth’s surface which are of unusual geological interest, are also presented in relief. Of especial local interest are a group of relief maps of the region about Chicago, which show the distribution of land and water in this district dur- ing a number of stages following the glacial period. Against the west wall are two large relief maps of the United States. One shows the distribution of rainfall and the annual tem- peratures and the other, the advance of the ice sheet during the glacial epoch. Hall 36: Petroleum, Coal, Clays and Sands.— -The east end of this hall is occupied by petroleum exhibits, beginning with oil sands of the American oil fields, followed by crude petro- leums, grouped geographically. The derivatives of petroleum, and specimens illustrating their uses, form another large col- lection. A model of the original Rockefeller refinery at Cleve- land is shown. Numerous oils refined from petroleum occupy a case in the center aisle. They range in use from burning and lubricating to medicinal oils. The great variety of uses of paraffin in the manufacture of familiar objects of everyday utility is interesting, and is illustrated by many specimens. The uses shown range from waterproofed clothes-pins and shot-gun shells to flowers for ladies’ hats and chewing gum. An exhibit of paraffin candles also forms a conspicuous part of this exhibit. With these familiar derivatives and uses of petroleum products are shown other important products and uses which are not so well known. Near the center of the hall a collection of coal is shown in which particular attention is paid to the coals of Westphalia and the Saar region which are of so much present interest. Accompanying the coal col- lection is a case showing the numerous substances obtained as by-products from coal. The products shown are obtained by the gas company of the city of London in the manufacture of illuminating gas. Although the case necessarily contains only a few of the thousands of coal by-products, the diversity and the brilliant colors of those shown, make it well worthy of attention. In an adjoining case is a duller colored but inter- esting series of the more important coal by-products obtained in this country. Adjoining the coal collections are cases con- taining oil shales and asphalts from many localities and a group of specimens showing the more important uses of asphalt. 16 In the center aisle a case contains diamonds and specimens of the rocks in which diamonds are found and of the minerals associated with diamonds. Two cases illustrate the occurrence and uses of peat. These demonstrate that peat may be used for many purposes besides fuel. Some of these uses are sur- prising. In a near-by case is a model of a lake in which peat is forming which illustrates the subject in great detail. A collection of graphite shown contains numerous specimens of crude graphite and associated rocks, as well as specimens illustrating the uses of this mineral. Of general interest also is a group of specimens showing all stages in the manufacture of the common lead-pencil. The west end of the hall is occupied by exhibits of clays, soils, sands, and other earthy materials. Two cases contain specimens which show how soil is formed, of what it is com- posed, the plant foods it contains and the nature of the several kinds of soils, such as loams and marls, which are ordinarily recognized by farmers. Another case contains soils grouped according to the more exact classification of the U. S. Depart- ment of Agriculture. This is followed by a collection of nu- merous soils arranged according to kind. In the large clay collection, the clays are arranged according to kind. A smaller group . of clays occupies four cases, and illustrates the numer- ous kinds of clay, and the relation of these kinds to each other. As most clays are used in the form of brick, tile, pottery or other burned ware, there appears with most of the specimens a little brick burned from the specimen itself. There are also shown collections of clay-like and earthy minerals of industrial importance. These include fuller’s-earths, mineral soaps, cement rocks, mineral pigments and sands. A synoptic collection illustrates the very diverse uses of the quartzes and sands, and is of particular interest. This collection shows a single specimen for each class of uses. It includes such well- known substances as common plastering and building sands as well as such comparatively little known things as a flask blown from pure, melted quartz for chemical use, and a speci- men of smoky quartz which the Chinese make into smoked spectacles. Hall 37: Frederick J. V. Skiff Hall. Ores, Marbles and Alkalies. — The east half of the hall is occupied by a collection of ores of the precious and base metals. The ores of each metal are grouped separately, except that gold, silver and lead ores are shown together. Under each group the speci- mens are arranged in geographical order according to country, state and mining district. In a case against the east wall, examples of those minerals which are frequently mistaken for gold are shown, and with them for comparison, gold from a variety of occurrences. Interspersed with the groups of ores are models which illustrate the methods of mining ore and of treating ores of the more important metals. A model of a gold mine shows the ordinary methods of mining ores. Treat- 17 ment of gold ore for extracting the gold is illustrated by two models, one of a stamp mill, the other of a simple form of cyanide plant. A model of a lead blast furnace illustrates one common method of extracting lead and silver from the ore. A model of an iron blast furnace and its accessories partly in section illustrates the fundamental process in the metallurgy of iron. One of the usual treatments for separating ore of any kind from admixed rock is shown by a model of a jig. With many of the lesser known metals and some of the others are placed small collections which illustrate the utilization of these substances. The uses of the rare metals are especially well illustrated in this way. To this collection has been added a series of those crystals which have been found useful for radio-communication. As the small specimens of which most of the collection is composed do not show sufficiently well the appearance of ore in mass, several large specimens of ore have been placed in individual cases. Near the center of the room a collection of native copper in a separate case merits attention. In the west part of the hall fifteen cases are filled with marbles and other ornamental stones from many parts of the world. The specimens are large enough to display to advantage the characteristic patterns of each variety. Building stones in the form of four-inch cubes fill five cases. Collections of industrial important non-metallic minerals occupy the west end of the hall. These include barite, fluorite, asbestos, mica, phosphates, grinding and polishing materials, gypsum and borax. With these are placed soda and potash collections, which include a large group of the Stassfurt potash salts. Hall 38 : Historical Geology. — The collections illustrate historical geology and paleontology, and are so arranged that, beginning at the south end of the hall, the forms of life which have characterized successive stages of the eartlTs history are illustrated in order from the earliest up to recent times. Thus the fossils which represent the life forms of each geological period may be found in the portion of the hall corresponding in position to that period in time. Beginning with two in- troductory cases, one illustrating methods of fossilization, and the other, comparisons of ancient and modern plants and animals, the fossils of the Age of Invertebrates, Age of Fishes, Age of Reptiles, Age of Mammals and Age of Man are shown successively. At the north end of the hall is a life-sized reproduction of the Moa, a gigantic ostrich-like bird of New Zealand which was contemporaneous with early man there. The skeleton of a Mastodon and another of the Mammoth, are the two most conspicuous objects in this end of the hall. These also repre- sent animals familiar to early man, as does the adjacent skeleton of the extinct Irish deer. In cases are skeletons of the European cave bear and the California sabre-toothed tiger, two of the more dangerous beasts encountered by primitive man. Among the specimens in another case is the skull of a 18 cave man which is still partially embedded in the rocky cave deposits. Immediately to the south of these is the portion of the hall which contains the fossils of animals and plants of the Ag*e of Mammals, which immediately preceded the time of man, and none of which were probably ever seen alive by human beings. The more conspicuous of these are the mounted fossils of large, extinct mammals. Some of these, like the Titano- theres, combine in one individual features which in modern animals characterize such unlike kinds as the hog and the elephant. Others, such as the American camel, which occupies a case by itself, resemble modern forms. Of special interest is a group of skeletons of the Leptomeryx, a deer of about the size of a small dog. The fossils of these small deer are crowded together in a single slab of rock which occupies an entire case. The great skeleton of the Dinosaur, Apatasaurus, occupies the center of the hall and dominates the entire collec- tion. This belongs to the Age of Reptiles, other fossils of which occupy the central part of the hall. Against the wall and in cases, are legs, ribs and backbones of even larger dinosaurs. The great horned skull of the Dinosaur, Triceratops, occupies a case by itself. Numerous other specimens illustrate dinosaurs and other Mesozoic reptiles of many varieties, includ- ing flying and swimming lizards. Fossils in the south part of the hall represent the life of the early part of the world's history. These do not include so many large specimens, as animals of these periods were as a rule of small size; but the smaller forms are shown in great variety. Crinoids from the Borden collection afford unusually perfect examples of these intricate and curious animals which lived in the time immediately preceding that at which the principal formation of coal took place. Many and diverse forms of corals, sponges and mollusks differing much from those of modern times, compose the larger part of this collection. With these are shown fossils of other animals, such as trilobites, which differed still more from modern marine forms. DEPARTMENT OF ZOOLOGY Halls 13, 15-22, First Floor Hall 13: George M. Pullman Hall. Horned and Hoofed Mammals. — This hall, running north and south and imme- diately west of Stanley Field Hall, is devoted to horned and hoofed mammals — game animals from all parts of the world. In the north end is a large habitat group of Alaska Moose, and thence southward are various representatives of the deer family, the antelopes, gazelles, wild sheep, goats, and oxen, terminating at the south end of the hall with the Bison group. 19 Hall 15: Mammals-Systematic. — This hall is at the right of the main north entrance to the Museum, and is entered by passing through the north end of Pullman Hall. With the exception of those represented in Pullman Hall, it con- tains members of the principal groups of mammals of the world, arranged so far as practicable, according to their rela- tionships. Beginning with the lower forms, the monotremes or egg-laying mammals of Australia and the pouched mam- mals or marsupials, it shows successively various groups, as the horse family, the tapirs, sea-cows, rodents, cat family, dog family, and terminates with the highest mammals, the monkeys and man-like apes. In the northwest corner of the hall is a large habitat group of American beavers. Hall 16: American Mammals-Habitat Groups. — Hall 16, next on the south from Hall 15, contains ten habitat groups of North American large mammals. From east to west, these are as follows: Virginia Deer, showing the difference in their appearance and habits, in the four seasons, Stoned Mountain Sheep, Polar Bear, Musk Ox, Prongbuck, Sonora Grizzly Bear, American Bison. Hall 17: Osteology-Skeletons. — Contains skeletons of the principal vertebrates or backboned animals. These include fishes, frogs and their relatives, birds, and mammals. At the right of the east entrance are the lower forms, fishes, etc., and at the left are the higher apes and man. In the center toward the west end is the huge skeleton of a right whale. Hall 18: Albert W. Harris Hall. Fishes, Reptiles and Amphibians. — The east half of this hall is devoted to fishes and the west half to reptiles and amphibians. The fishes are arranged in two series; one showing repre- sentatives of the principal orders and families of fishes, and the other showing habitat groups and special collections of Atlantic and Pacific food and game fishes, and also Chicago Market fishes. The collection of reptiles includes representatives of the lizards, snakes, turtles, and crocodiles. A special exhibit con- tains North American amphibians and reptiles reproduced in celluloid. Hall 19: Marine Invertebrates-Insects. — The invertebrates include many of the myriad forms of life found in the sea- corals, crinoids, sponges, sea urchins, star fishes, crustaceans, and many others. At the western end of the hall are several cases of insects. One contains poisonous insects, like taran- tulas, centipedes, scorpions and their allies, and the seventeen- year cicada or locust in all of its stages; another contains specimens and enlarged models illustrating the various stages, diseases and products of the silkworm, as well as the life his- tory of a swallowtail butterfly and two common American giant silkworms. In a third case are two habitat groups with illustrated labels, the one showing the insect life of the dune 20 region near Miller, Indiana, and the other portraying the life history of the destructive Tomato Worm Moth. Hall 20: Birds-Habitat Groups. — Eighteen bird groups with painted backgrounds are shown, mostly in large sectional cases with four groups to each case. The majority of the groups are of North American birds, conspicuous among which are the Northern Loon, Golden Eagle, California Condor, Whooping Crane, Wild Turkey, White Pelican, and Ruffed Grouse. Near the west end of the hall is a large case con- taining four groups from tropical America and including the Flamingo, the Jabiru Stork, Horned Screamer, Scarlet Ibis, and Oilbird or Guacharo. At the extreme west end of the hall is a group of Alaskan water birds from the Pribilof Islands, and a group of albatrosses and other mid-Pacific birds from the island of Laysan. Hall 21: Birds- Systematic. — A systematically arranged col- lection of birds including representatives of the more impor- tant orders and families. Cases on the north side of the hall are devoted to North American birds, and those on the south side to birds of foreign countries. Hall 22: African Game Animals. — This, the largest hall, occupies the entire western end of the building. In the north- ern half are groups of large African mammals collected and prepared by C. E. Akeley — Koodoos, Zebras, Buffaloes, and various antelopes. In the southern half are other antelopes, Wart-hogs, Hyaenas, a collection of large apes, mostly Gorillas and Chimpanzees, and also a group of Bornean Orangs and of Proboscis Monkeys. H. N. HIGINBOTHAM HALL Hall 31: Gems and Jewels. — Second floor at head of stair- case leading from the south end of Stanley Field Hall. This hall contains large and valuable collections of gems and jewels of both ancient and modern origin. In the five central cases of the hall are shown examples of nearly every known gem, represented both by cut and uncut specimens. Many of the specimens are of historical interest and of high intrinsic value. Special note may be made of the DeVrees engraved diamond, the Hope and Tiffany aquamarines, the Russian topazes, the series of cut amethysts and the Sun God opal. The largest known specimen of gem topaz and a number of fine emeralds, aquamarines and tourmalines from Brazil have lately been added to the collection. Crystallized and wire gold, gold nuggets and native platinum may also be seen here. The nine wall-cases contain Egyptian and classical jewelry, Roman and Italian cameos and intaglios, jewelry of the Near East, Algerian jewelry, a remarkable collection of jewelry from India, and prehistoric American gold ornaments. 21 THE N. W. HARRIS PUBLIC SCHOOL EXTENSION This department prepares small portable cases of natural history and economic exhibits and delivers and lends them to the schools of Chicago. This direct and effective way of extending the museum into the classrooms of the schools was made possible through the benefaction of the late Norman Wait Harris, who pro- vided in 1911 an endowment of $250,000. This endowment has been supplemented by contributions in 1919 of $25,000 and in 1923 of $100,000 from members of the Harris family. Nearly 800 cases are at present available for this educa- tional work. Other cases are being prepared. At the begin- ning of the school year two cases are sent to each school for a period of two weeks. At the end of that time they are taken to other schools for the same period and two other cases are left in their stead. Deliveries to the schools are made by motor truck. Ten examples of these cases are exhibited at the south end of Stanley Field Hall.
