REPORT OF NATIONAL, MUSEUM, 1924 93 



The watercraft collection was very materially enhanced in quality 

 by two accessions of steamship models. The Canadian Pacific Rail- 

 way Co., Montreal, Canada, through Walter Maughan, steamship 

 passenger manager, generously loaned a model of the steamship 

 Empress of Russia, one of the vessels plying between Vancouver and 

 the Orient. The model was made in Glasgow, Scotland, and is per- 

 fectly executed in every detail as far as exterior is concerned. It is 

 approximately 12 feet in length and is shown in an appropriate 

 exhibition case, which also was loaned to the Museum. The second 

 accession is that of the model of the steamship Leviathan, which was 

 transferred to the Museum from the office of the Alien Property 

 Custodian, which office secured the model at the time of the seizure 

 of other German property upon declaration of war with that coun- 

 try. This model, too, is complete in every detail as to exterior and 

 measures 18^ feet in length over all ; in other words, it is approxi- 

 mately one-fiftieth actual size. Both of these accessions do much 

 toward rounding out the collection of models visualizing the develop- 

 ments in steam transportation. 



In mineral technology very important and valuable additions were 

 made to the glass-industry exhibit through the generosity of the 

 Corning Glass Works, Corning, N. Y. The series of objects includes 

 two scale models of the modern glass-melting furnaces, known, re- 

 spectively, as the pot furnace and tank furnace; 174 specimens of 

 chemical, railway, industrial, domestic oven, and art glassware; and 

 a full-size glass-blowing machine such as is used in the making of 

 incandescent electric-light bulbs. With this accession, the glass 

 industry exhibit may be said to be approaching more nearly to a com- 

 plete exhibit. Mention was made in the last annual report that the 

 divisions' own preparators were engaged in the preparation of a 

 model visualizing the land pebble phosphate mining industry of 

 Florida. This model was accessioned during the current year and 

 placed on exhibition. Its construction would hardly have been 

 possible had it not been for the whole-hearted assistance rendered by 

 the Morris Fertilizer Co., Chicago, 111. The model is 16 feet long 

 and 30 inches wide^nd visualizes the mining and preparation of this 

 valuable mineral product. For addition to this exhibit the Morris 

 Fertilizer Co., Atlanta, Ga., donated 10 samples of land pebble 

 phosphate rock in the various stages of its preparation, and from 

 photographic negatives supplied by this company the Museum's 

 photographic laboratory made eight transparencies showing con- 

 ditions in and about this enterprise, which are exhibited above the 

 model. As a further addition to its earlier donation to the division's 

 exhibit of asbestos and asbestos products, the Keasbey & Mattison
