132 KANSAS ACADEMY OF SCIENCE. 



A pamphlet describing the history of the oil-fields, the origin and 

 description of the different areas was distributed in connection with 

 this exhibit. The Commercial Club of Chanute, late in the summer, 

 m de a special exhibit of crude oils and photographs of the wells. 



LEAD AND ZINC. 



Kansas at the present time holds first rank in the production of 

 metallic zinc, or spelter. The producing area of lead and zinc is not 

 large, and is found around Galena, in Cherokee county. The lead is 

 smelted at Galena by the Galena Smelting and Manufacturing Com- 

 pany, which made an exhibit of pigs of lead piled up in a pyramid con- 

 taining one and one-half tons. The fumes and dust from this smelter 

 are caught in large cylinders and then fused in a furnace, giving a 

 variety of lead known as "lead smoke." This "smoke" has a prismatic 

 structure, and the process of its manufacture at this plant is superior 

 to any other used. The exhibit of this material in the Kansas space 

 attracted attention on account of its value and peculiar appearance, as 

 well as from its name of "lead smoke." 



The metallic zinc was shown in our exhibit by fifty-pound plates 

 of spelter loaned by the Granby Mining and Smelting Company from 

 their smelter at Neodesha. The main metallic zinc exhibit from Kan- 

 sas was made by the Lanyon Zinc Company, from its works at lola. 

 Gas City, and Lanyonville, in a separate space of 2000 square feet 

 under their own name and control. This exhibit showed all the 

 varied uses of metallic zinc — for rods, roof-tile, wash-boards, stair work, 

 inside metallic finish, etc. This booth had the name "Kansas" promi- 

 nent • and while in no way connected with the state display, it was 

 still an advertisement of the Kansas resources, and was so intended 

 by the company. Mr. Drake, president of this company, took great 

 interest in our work and tried to secure space near us, so as to bring 

 these displays together. This exhibit received the grand prize. 



On the Kansas space a pyramid was constructed of choice lead and 

 zinc ores, with plates of metallic zinc at the base, and the whole 

 capped by an eagle and ball made of the sheet zinc. This pyramid 

 thus showed in one column the ores, the metal, and the metal rolled 

 into sheet zinc worked over into a patriotic emblem. Some of 

 the finest cubes of zinc in the building were in our exhibit. Two 

 show-cases were filled with choice specimens of lead and zinc ores 

 from Galena. A pyramid case was filled with zinc silicate ores and 

 lead and zinc sulfide ores. There was one mass of lead crystals 

 weighing 700 pounds and another weighing 300 pounds, both from 

 Galena, and the former, known as the Carney specimen, received a 

 special award.
