the Montana formations, described by the .same author in Bulletin 163 

 of the Survey; plants of the Payette formation descri))ed by Dr. Knowl- 

 ton in the Eighteenth Annual Report of the United States Geological 

 Survey; plants from the Cascades of the Colum])ia; plants from 

 Esmeralda County, Nevada; a fine series of cycads from the Freezeout 

 Hills north of the Medicine Bow River, Carbon County, Wyoming, 

 collected by Mr. Charles Schuchert and Dr. Lester F. Ward. 



PROGRESS IN INSTALLATION. 



The progress in caring for the collections has been eminently satis- 

 factory. The confusion incidental to the erection of the new galleries 

 has been practically overcome, and it is not too much to say that the 

 collections as a whole are in better condition now than ever before. 



The installation of the systematic series in the Section of Applied 

 Geology on the gallery in the southwest court (Plates 1 and 2) has 

 been practically completed and some 2,500 new labels have been sup- 

 plied. The reserve collection of ores has been arranged in the storage 

 drawers beneath the rail cases and a complete card catalogue of the 

 same prepared. Great changes have been made incidentally on the 

 ground fioor of the court, which is now given up to the building-stone 

 collection; the collection illustrating the mineral resources of the 

 United States, and various special collections, as the Tenth Census col- 

 lection of iron ores; rocks and ores illustrating the geology of Lead- 

 ville; and collections illustrating the metallurgy of gold, silver, lead, 

 copper, zinc, and iron. 



Progress in the Section of Vertebrate Paleontology has been slow, 

 since the energies of the division have been occupied almost entirely 

 in making a temporary place for the Marsh collection. One hundred 

 and thirteen boxes of this collection have been opened and their con- 

 tents distributed and catalogued. Fifteen skulls of TltanofJierhan^ 

 and the limb bones of a large dinosaur have been mounted for exhibition. 



In the Section of Invertebrate Paleontology Mr. Schuchert reports 

 the mounting of 2,850 specimens of Triassic, Jurassic, Cretaceous, 

 Ordovician, Silurian, Lower Helderberg, and Lower Carboniferous 

 fossils. In addition, the 1. H. Harris collection of Cincinnati fossils, 

 comprising 75 boxes, has been unpacked, assorted, and prepared for 

 installation. A large amount of material has been also added to the 

 duplicate collections. 



In the Section of Paleobotany the work of installing the Lacoe col- 

 lection has been practically completed. Many of the older Museum 

 collections which have never been satisfactorih* cai'ed for have been 

 overhauled and catalogued and numbers painted upon the specimens 

 in a way, it is hoped, to avoid possible confusion in the future. 



The work of building storage racks on galleries of the east south 

 and west south ranges has been completed and satisfactory progress 

 made in installing in the drawer space thus afforded material belong- 

 ing to the sections of Vertebrate Paleontology and Paleobotany.
