gypsum, and samples of clay. From Piauhy there were bottled 
sulphurous mineral waters, talc, kaolin, graphite, concretionary 
hematite, and fossil wood. From Sergipe, crystalline limestone and a 
compact, light-colored argillite used for construction. From Ceara, 
porphyritic granite, a red granite coarsely crystalline, fossil cetacean 
bones from Cruxati, copper carbonate from Mildgres, concretions 
with fossil fishes, and tile work. Alagoas sent pottery products, 
particularly water-jars made from the clay of Penedo on the Rio 
Francisco, noted for their porosity and consequent evaporating 
capacity and cooling power, the most preferred carafes in Brazil. 
The exhibit also included granites and marbles, among the latter a 
dark and light-banded crystalline crumpled variety; garnets and 
black tourmalines. From Rio Grande do Norte, there were soap- 
stone, beryl, and aquamarines; Cretaceous and Tertiary limestones; 
yellow bricks, salt from the evaporating pans of Caico and Macau, ~ 
and gypsum from Carambas. Rio Grande do Sul exhibited bituminous 
coal from the Permian; agates from the Triassic trap sheets; wolfram- 
ite from Rio Pardo; cuprite, indigolite from Bagé; molybdonite, 
covellina, native copper from Colonia militar; tin ore; besides 
artificial stone-ware and colored tiles. From the state of Parad, the 
exhibits consisted chiefly of clay products, such as bricks and drain- 
pipes from Cameté and Belem. From Matto Grosso there were gold 
and diamonds from Coxipo mirim; diamonds and. sapphire gravel 
from the Rio Coxim; gold and diamonds from a basal conglomerate 
beneath a Devonian sandstone; besides ores of manganese, -hematite, 
and exhibits of limestones. ‘The state of Amazonas was represented 
by gneisses and schists, silicified wood, artificial stone-ware, tiles and 
bricks manufactured from Tertiary clays. Goyaz furnished musco- 
vite in merchantable plates, gold, galena, amethyst, rutile, diamonds, 
yellow quartz (now exported), rose quartz, limonite, soapstones, and 
millstones. Maranhao had an exhibit of gold. Bahia supplied a 
collection of minerals, including manganese from Napareth, muscovite 
from Conquista (said to exist in commercial quantities), monazite 
sands from Prado, tabatinga (ochreous clays of a variety of colors), 
copper carbonate from Bom Fim, manganese, limestone, a fine com- 
pact brownish limestone with a tendency to a shelly fracture and often 
horizontally banded from Campo Formoso; granites and gneisses, 
including a red gneissoid granite from Jacaricy, tale blocks from 
Caruanyba, lithographic (sic) limestone from Carinhanha and Bom 
Jardim; clay products, including red porous water-jars. The state 
of Santa Catharina furnished exhibits of the Permian coal, manganese
