REPORT OF DEPARTMENT OF METALLURGY. 245 



to clearing out the space and making it available for exhibition pur- 

 poses. The force of workmen in the department being considerably 

 increased, this work was undertaken with as much vigor as possible 



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

 this material had never been entered in the catalogue, and it was m-c 

 essary, therefore, to make 4,182 oew entries, embracing 7,540 new speci 



mens. Of these the most important collect ions were the steel exhibits 



of Park Brothers & Co., Eussey, WellsA Co., and Carnegie Brothers, 



Pittsburgh, Pa.J a collection of rolled iron shapes from the Phu-nix Iror 

 Company; a very Large collection of tire-brick from many localities; ;, 

 collection of ores from Colorado; and t wo collect ions representing the 



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



I'lio'iiixville, Pa. 

 The entire collection of foreign ores was overhauled and put into 



shape for exhibition. This collection embraces a very valuable series: 

 from the Krupp 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 specimens of 

 tin ores and their associates. 



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

 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-room 

 had been so far cleared that it w r as thrown open for exhibition purposes, 

 and the work was continued until the material for the New 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 ale 

 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, ami: 

 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 preparation 

 of the catalogue of the collection 10,9G0 entries have been made, cover- 

 ing 15,271 specimens; and in the preparation of the card catalogue 

 9,337 cards, covering L2,363 specimens, upon which 389 determinations 

 of mineral species have been made, have been written.
