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, 

 porphj,Titic granite, a red granite coarsely crystalline, fossil cetacean 

 bones from Cruxatu, copper carbonate from Milagres, 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 Bage; molybdonite, 

 covellina, native copper from Colonia militar; tin ore; besides 

 artificial stone-ware and colored tiles. From the state of Para, the 

 exhibits consisted chiefly of clay products, such as bricks and drain- 

 pipes from Cameta 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, talc 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
