REPORT OF DEPARTMENT OF METALLURGY. 245 



to clearing out the sjnice and niakinji- it available for exhibition ]>nr- 

 poses. The force of workmen in the department being considerably 

 increased, this work was undertaken with as much vigor as i)ossil)ler 

 and continued until the middle of June. It was found that nuuh of 

 this material had never been entered in the catalogue, and it was nec> 

 essary, therefore, to make 4,182 new entries, embracing 7,540 new si)eci- 

 mens. Of these the most important collections were the steel exhibits 

 of Park Brothers & Co., Ilussey, Wells & Co., and Carnegie Brothers^ 

 Pittsburgh, Pa.; a collection of rolled iron shaiies from the Phoenix Iron- 

 Company ; a very large collection of firebrick from many localities ; a. 

 collection of ores from Colorado; and two collections representing the 

 smelting of copper, one from Ducktown, Tenn., and the other fromi 

 Phceuixville, Pa. 



The entire collection of foreign ores was overhauled and put into* 

 shape for exhibition. This collection embraces a very valuable series 

 from the Krnpp Works, Essen, Germany ; collections representing the 

 ores of Sweden, Russia, Spain (very large and complete), Portugal, Italy^ 

 Turkey, Japan, Mexico, and the Australasian colonies. This latter col- 

 lection is especially valuable on account of its richness in si^ecimens of 

 tin ores and their associates. 



The entire collection of coals belonging to the department was er- 

 amined, and it was found that many specimens had seriously decom- 

 posed, and were therefore of little value. Such as were yet in good 

 condition, and from localities difficult of access, were saved and put 

 upon exhibition. By the middle of April a section of this work-rooni 

 had been so far cleared that it was thrown open for exhibition puri)oseSy 

 and the work was continued until the material for the Kew Orleans Ex- 

 position began to arrive, when it was necessarily suspended. 



At the opening of the year very little progress had been made in the? 

 regular installation of the collection, although many specimens were 

 available. In connection with the work of clearing out the work-room, 

 the installing of the specimens was taken up, and an attempt made at 

 temporary arrangement. This has so far proceeded that the very val- 

 uable collection of native ores is now installed in the large black-walnut 

 cases. A portion of the Census iron ores has also been installed, and 

 the steel exhibit of Park Brothers & Co., the rolled shapes from the 

 Phoenix Works, portions of the Kirkaldy test specimens, and a por- 

 tion of the tack exhibit have been placed on exhibition. 



A large amount of the foreign material has been displayed, but it has 

 not yet been systematically arranged and installed. 



Nineteen letters of information and report upon specimens submitted) 

 have been made, together with nine other reports. In the preparatioa 

 of the catalogue of the collection 10,900 entries have been made, cover- 

 ing 15,271 si)ecimens ; and in the i)reparation of the card catalogue 

 9,337 cards, covering 12,303 specimens, upon which 389 determinations, 

 of mineral species have been made, have been written.
