Russia. 
The floor space occupied by this exhibit is about 60x70. 
It was tastefully arranged and decorated with flags. One of 
the most striking objects on entering the enclosure was the 
inevitable objective presentation of the gold yield of Siberia 
and European Russia by means of three gilt pyramids made of 
proper sizes to represent the gold mined from 1745 to 1891. 
The product of East Siberia between these 
two years was 1,097,232 kilogr. 
Western Siberia 109,990 " 
European Russia 458,844 " 
Silver and lead ores were shown from the Sadon mine and 
the Alaghire smelting works. Zinc ores, metallic zinc and 
other products from the Dombrowa, and a few specimens of 
■cinnabar and manganese ore from South Russia, also nickel 
and cobalt; iron ores from the Nontruska and Mada villages ; 
small specimens of magnetite from the Blagodat mine in the 
Blagodat mountain, the latter illustrated by drawings and 
models. A model is shown also of the Choroblagodotsky 
iron works. Cases of iron wares, thin sheet iron and other 
interesting products and tools are exhibited in connection 
with these. Handsome specimens of azurite from East 
Siberia are shown. 
The individual exhibits are good, but the arrangement, 
though pleasing to the eye, lacks some system, which would 
facilitate its study, and the labels were strikingly inadequate. 
The rock salt, petroleum product, sulphur, etc., besides the 
finely executed geological map, the latter probably under the 
direction of the able Chief Geologist Serge Nikitin, deserve at- 
tentive study and merit commendation. 
Spanish Colony ok Cuba. 
About 48x60 feet was accorded to the exhibit of this coun- 
try. A collection of galena and other ores in cases and jars 
without labels were among the first objects observed; speci 
mens from Santiago de Cuba, containing a large representa 
tion of the Spanish American Company's ores from Y"ucca, 
Perseverance, Union, etc. Several casesof minerals were fol- 
lowed by stands supporting large blocks of galena from the 
Arroyanas mine, province of Jaen ; ;i model of an open retorl 
furnace for mercurial ores, in wood, four feel long; iron and
