small amount of clay. It contains 

 neither magnesia nor iron except such 

 as exist in the clay or foreign material. 

 The carbonate of lime' is .'^deposited 

 from the water of the spring after its 

 carbonic acid gas is liberated, and the 

 process of incrustation is accelerated 

 by the spreading out of the water after 

 reaching the surface of the ground and 

 by the rays of the sun which play upon 

 the mountain on this, its southeastern 

 -exposure, during most of the day. The 

 water of the spring is what is known 

 as "a moderately hard lime water," 

 is clear and sweet, and not objection- 

 able for drinking purposes. 



In this part of Missouri — the south-

 Science and the collector of curios may

Indian relics are still to be found in 

 considerable variety and numbers. In 

 the district in question one may quite 

 easily obtain quantities of arrow heads, 

 spear-points, stone knives, fragments 

 of pottery, etc. On one small hill, or 

 mound, about eight miles east of the 

 spring just described, we found a veri- 

 table arrow-head factory. In the sur- 

 face soil of this hill, white flint is very 

 abundant and may be found in all sizes 

 from huge rocks down to fine chips. 

 On top t?he ground the chips are espec- 

 ially numerous and upon inspecting 

 these somewhat closely it was found 

 that many of them had been worked 

 into special forms. In fact, pieces of 

 Indian arrow-heads were strewn all 

 over the hill. Tips, butts, barbs, half- 

 made heads, etc., could be picked up 

 in numbers, but only a few unbroken 

 and well-formed specimens were found. 

 Imperfect spear points and fragments 

 of other stone implements were also 

 taken from the hills. From the abun- 



dance of these imperfect specimens 

 and the dearth of good ones — as well 

 as from the evidence of stone-working 

 as maifested by the innumerable small 

 flint chips — it is reasonable to con- 

 clude that this was a favorite 

 spot for the manufacture of stone 

 weapons by a race of people now al- 

 most extinct. The place is most fav- 

 orable for camping. Just north of 

 this hill rises another and between the 

 two flows a beautiful stream of clear 

 spring water. The space between the 

 foot of the hills has, in places, a width 

 of about 300 yards, in others, not more 

 than 50 feet. This narrow valley with 

 its trees and verdant grasses probably 

 furnished the ground upon which the 

 wigwams were pitched. Here the old 

 men and young braves doubtless fash- 

 ioned the hunting and war arrows and 

 spears for the hunters and warriors of 

 the tribe. 



Numerous Indian graves have been 

 found on the adjoining hillside.

To widen the fairway of Port Jack- 

 son (Australia), a submarine reef is 

 being removed. An opportunity of 

 going down with the divers employed 

 thereon was kindly offered to myself 

 and a scientific friend by the officer in 

 charge of the operations. So tempting 

 an invitation was, of course, accepted 

 with delight. Often in imagination 

 had we wandered on the ocean floor, 

 peering into ghastly wrecks of ships 

 sunk long ago, fighting with some huge 

 shark or monstrous octopus, and gath- 

 ering treasures of science or heaps of
