GEOLOGICAL SUEVEY OF THE TEERITOEIES. 217 



quietly from a syeuite on the left bank, and flows in a slender stream 

 into the Fontaine. A few bubbles of gas are rising continnallj^ to the 

 surface, but the excess of carbonic acid is not iDroportionately so great 

 as in the other springs. There is a comparatively small deposit of car- 

 bonate of lime in the bed of the little canal which the water has worn 

 a^ay through the rock, and none in the ■s'icinity which could be traced 

 to the overflow of the spring. The water shows no trace of volatile 

 substances which would escape during the evaporation, except carbonic 

 acid. Its reaction is feebly alkaline. 

 The salts held in solution are as follows: 



Much— Is^aO . CO2 

 KO . CO2 



OaO . CO2 

 NaCl 

 AI2O3 

 Trace — Fe . 



The Iron tipring. — This showed the presence of that metal from which 

 it is named by a very insignificant deposit of the familiar brown oxide 

 in its vicinity. ISTo volatile substances in the water. Eeaction alkaline. 

 The salts in solution were : 



*K0.C02 

 NaO . CO2 

 *Li0.2C02 

 (Probably as carbonate) — FeO . CO2 



KaCl 

 AI2O3 



The amonnt of iron in solution in the Iron Spring was unnsually 

 small ; the aoiount of alumina being greater and that of lime less than 

 in "The Doctor." 



The Beast Spring. — This is next to the largest. A continuous line of 

 bubbles of carbonic acid is perpetually^ ascending from the bottom. The 

 taste of the water is not so pleasant nor pungent as that of the other 

 springs. 

 The analysis showed — 



E^aO . CO3 



KO.CO2 . 



Na.Cl 



S 



AI2O3 



The Batliing Spring was not analyzed, but its salts cannot be very dif- 

 ferent from those of the "Beast." A noticeable feature of this latter is 

 the small i)er cent, of sulphur which probably is present in soda or 

 potash alum. The ebullition of gas in the "Bathing Spring" is enor- 

 mous and Ivceps the water in a constant state of agitation. 



This spring bursts out from a syenitic rock, but by the overflow of its 

 waters it has covered the latter with a crust of carbonate of lime sev- 

 eral feet in thickness and much broader than is the case at the celebrated 

 High Eock Spring of Saratoga. It is as if a white tablecloth were laid 

 over the rock. I have never seen so violent an escape of gas except 

 from the Salina near Kissingen, in Bavaria. 



* The iiotasli aud litliia reactious with the blowpipe are sufficiently distingnishahle 

 to enable one possessing the requisite exxierieuce to recognize them with a little trouble ; 

 but in the tield, Avliere time is .short and opi>ortunities meager, it is not always easy to 

 do this. I venture to give them both without stating which predominates, reserving 

 the solution of this question for the fh'st opportunity which offers in the future.
