W. F. Hillebrand — Zinc-hearing Spring Waters. 419 



Shoal Creek and four and a half miles southwest of Joplin is a 

 low bluff, perhaps 18 feet high, formed by a portion of the 

 Burlington Chert Beds. At the base of this bluff, in a shallow 

 depression, is a series of springs extending for a distance of 

 perhaps 150 feet and emptying their waters into the above 

 mentioned depression, wherein a sluggish current is produced 

 and a deposition of a slimy white precipitate takes place. 

 They vary in size, discharging from one-half to three gallons 

 of water per minute, and about 30 gallons, or 150 to 160 liters, 

 in the aggregate. So far as can be judged by the taste they 

 vary also in composition, some waters being much stronger 

 than others. 



The two samples analyzed were taken by Mr. James A. 

 Reeves, of Joplin, from springs about 90 feet apart, designated 

 as the East Spring and the West Spring," which were not only 

 the most powerful, but which also, judged by the taste, fur- 

 nished the strongest water. The composition as given below is 

 that of the water after having stood in sealed bottles for two 

 or three weeks and having been then separated by filtration 

 from a whitish flocculent deposit which was probably formed 

 after collection of the samples, in which case the reported 

 composition does not exactly represent that of the water as it 

 issued from the spring. As received the waters were clear 

 and limpid above the sediment, they were neutral to litmus 

 paper, and their density differed but little from that of pure 

 water, that of No. I being 1-0006 at 20|° C. The samples 

 were too small and time was too valuable to admit of exhaust- 

 ive examination or of duplication of determinations. The 

 analyses are as follows :
