have been augmented by five others, installed with particularly inter- 

 esting material, as follows : one case showing the growth and utilization 

 of the Creeping Palms (the rattan and ivory-nut palms) ; another 

 case illustrating by a fine series of specimens the character and utili- 

 zations of the wood, ekels, and leaf of the Cocoanut Palm; another 

 displays the various uses of the cocoanut itself, its "meat" and "shell ;" 

 another has been arranged to illustrate the various kinds of fruits in 

 the Palmae and their utilization ; another shows the fibers and other 

 products of the Black Palms (Borassus, Arenga, and Coryphal), the 

 fifth being devoted to the Bermuda Palmetto (Sabal Blackbeumianun). 

 The Lily Family now has representation in a complete case of various 

 products and characters, as has also the Banana Family. A half- 

 case has been installed with interesting products of the Ginger Family, 

 another with a fine series of the fruits of the Walnut Family, and a 

 third adds to the former representation of the Fig Family a complete 

 series illustrating the manufacture of Siamese and Laos papers from 

 the bark of Streblus asper. A full case has been installed with various 

 fibers of the Nettle Family, and another devoted to the wide range 

 of fibrous materials yielded by the Mallow family. The three cases 

 formerly devoted to the Legumes have been augmented by two others 

 devoted to the Ground-nut, Gums, and various fruits and seeds of 

 economic value or botanic interest. A half-case now inaugurates an 

 exhibit of the Rose Family; another the Cycads and their starches, 

 the Yews, the Rushes, the Naiads, and the Candle trees; and a third 

 has been devoted to the Sedges and their utilization. A beginning 

 has also been made in the proper casing of the extensive dendrological 

 collections of the Department, three cases having been installed with 

 the unique series of Jamaica woods, and a fourth devoted to a complete 

 illustration of the products of destructive distillation of wood. In 

 addition to these installations, considerable time has been devoted 

 to the further and more complete organization of the study-reference 

 material. This valuable series (duplicating for the purposes of 

 investigators the specimens entering into the permanent installations) 

 is daily proving its great usefulness to the ends of the Department. 



The most important work of installation in the Department of 

 Geology has been the entire reinstallation of the collections of syste- 

 matic mineralogy and structural geology. These collections occupied 

 Halls 63, 64 and 65. All former cases were removed and new cases 

 provided for the collection throughout. Twenty-two wall cases 

 and sixteen floor cases were provided. Each wall case has two
