CORRESPONDENCE.

DEPARTMENT OF THE INTERIOR,
Washington, August 29; 1899.

Str: There are on the Hot Springs Reservation, Hot Springs, Ark.,
a number of hot springs the water from which is, under the supervi-
sion of this Department, supplied to certain bath houses for the bene-
fit of the public. The waters of these springs are claimed to have
medicinal qualities, and from the number of cures that have been
effected from the use thereof it is believed to be true. No official
analysis, however, has ever been made of the properties of these waters,
and I therefore have the honor to request to be advised as to whether
it will be practicable for an analysis of the waters of these hot springs
to be made by the chemists of your Department.

Any expense that may be incurred in the matter will be defrayed
from the Hot Springs Reservation fund. <A copy of the last annual
report of the superintendent of the Hot Springs Reservation is inclosed,
in which will be founda list of the hot springs, their relative tempera-
ture, elevation, and character of the flow of the water therefrom.

Very respectfully,
Tuos. Ryan,
Acting Secretary.

LETTER OF TRANSMITTAL.

UnitTeD States DEPARTMENT OF AGRICULTURE
BuREAU OF CHEMISTRY,
Washington, D. C., December 9, 1901.

Str: I beg to transmit herewith the results of the work done in this
Bureau in the examination of the waters of the Hot Springs of Arkan-
sas. This work was undertaken in harmony with the request made to
you by the Secretary of the Interior, and under the instructions which
you gave me in acceding to that request.

After a careful preliminary study of the nature of the problems to
be investigated, I, with your consent, detailed Mr. J. K. Haywood, one
of my assistants and an expert in water analysis, for the purpose of —
undertaking theanalysesdesired. Mr. Haywood was given full instruc-
tions in regard to the character of the work which he was to perform,
and in compliance with those instructions proceeded to Hot Springs,
where he made the necessary study of the waters at the springs them-
selves. He also secured abundant samples of the waters for the
examination which could be made in the laboratory of this Bureau.

Mr. Haywood has given in the following pages the results of his
investigations, together with certain opinions in regard to the thera-
peutic values of the water: s, which it is deemed advisable should accom-
pany the report. In regard to these opinions it is only proper to say
that they are not our own, but are based upon the authorities which
are regarded as reliable in such matters. It must not be understood,
howeve er, that these opinions in regard to the therapeutic value of the
waters have ¢ any Official indor sement whatever from this Bureau. We
have not made any experimental determinations of the healing quali-
ties of the waters, nor have we studied their effects on invalids. These
opinions are subject to correction or change, in the light of further
investigations made by us or by other parties, and must not be accepted
with too much consideration. The value of these thermal waters in
certain chronic cases of disease is well established; but how this thera-
pou action is secured is not a proper subject of investigation by this

ureau.

HOT SPRINGS, ARKANSAS. Jud

This report is a valuable contribution to our knowledge of thermal
waters, and I believe it will be found thorough and accurate, repre-
senting the sum of our knowledge of these waters at the present time.

I have the honor to request that you transmit this bulletin to the
honorable the Secretary of the Interior.

Respectfully,
Ee Wis Ways,
Chief of Bureau of Chemistry.

THE CHEMICAL COMPOSITION OF THE WATERS OF THE HOT
SPRINGS OF ARKANSAS, WITH AN ACCOUNT OF THE METHODS
OF ANALYSIS EMPLOYED AND THE MEDICINAL VALUE OF
VARIOUS SUBSTANCES USUALLY FOUND IN MINERAL WATERS.

By J. K. Haywoop,

In Charge of Laboratory of Insecticides and Agrieultural Waters.

[Analyses performed at the Bureau of Chemistry, United States Department of Agriculture, under the
direction of H. W. Wiley, chief chemist. ]

INTRODUCTION.

The Hot Springs of Arkansas are situated in Garland County imme-
diately adjacent to Hot Springs City, on the western slope and at the
base of Hot Springs Mountain, a spur of the Ozark Range. Origi-
nally there were said to have been seventy-one of these springs, but
on account of improvements on the mountain, necessitating the merging
of two or more springs into one, also by reason of the natural changes
in the subterranean course of the water, this number has been reduced
to forty-nine. Forty-four of these are either in use or can easily be
used by making some slight improvements. Five rise from the bed
of the creek situated at the base of the mountain, and are consequently
lost in the cold water of the stream. Besides the hot springs men-
tioned above, there are two cold springs in close juxtaposition on the
northern slope of the mountain.

In making the analyses of these waters, because of changes apt to
take place in certain constituents on standing, some of the determina-
tions were made directly on the ground within one hour after the
samples had been taken. The determinations mentioned are nitrogen,
oxygen, carbon dioxide (free and as bicarbonates), nitrites, nitrates, oxy-
gen consuming capacity, and free and albuminoid ammonia. Besides
this, 10-gallon samples of each spring were shipped to Washington,
D. C., where determinations of the various mineral constituents were
at once begun. Each day the temperature of the spring then under
analysis was taken; finally at the end of the chemist’s stay at Hot
Springs the temperatures were retaken in a single day, as well as the
flow of each spring.

12 HOT SPRINGS, ARKANSAS.

The constituents determined in each of the 44 hot springs and in the
2 cold springs include the following:

Oxygen, consuming capacity. Chlorine.
Albuminoid ammonia. Borie acid.

Free ammonia. Phosphoric acid.
Lithium. Nitric acid.
Sodium. Nitrous acid.
Potassium. Sulphuric acid.
Magnesium. Silicie acid.
Calcium. Carbonic acid.
Tron and aluminum. Bicarbonie acid.
Manganese. Nitrogen.
Arsenic. C )xygen.

Todine. Hydrogen sulphide.
Bromine. Total solids.

Besides these substances, the following were determined in spring
No. 15 (Big Iron), which is not only the largest Spon in the group
but will serve as an example of all the other springs, since the chemical
composition of all of them is so nearly alike:

Barium.

Strontium.

Fluorine.

In reporting the results of analysis, the bases and acids are given in
parts per million of the positive and negative lons, except In the case

of silica, which, in the present state of our knowledge, we can only
report as such, not going into the question of how much is present as
the silicic acid ion and how much present as free silica. Tron and
aluminum are always reported together, because of the great difficulty
in separating such small amounts of the two as appear in these waters.
Wherever iron and aluminum are involved in any calculation the
whole is considered as iron and given an atomic weight of 56. This
is doubtless practically correct, since a test of the residue from a large
volume of one of the springs showed that the iron-aluminum precipt-
tate consisted almost entirely of iron and contained aluminum, at the
most, only in traces.

Because of the fact that these analyses will doubtless be referred to
by many who have had no chemical training, the author has thought
it best to combine the acids and bases in a hypothetical combination,
thus reporting them as salts. That such a combination has no basis,
in fact, is doubtless true, since we have every reason to believe that

where various basic and acid ions are present in solution no base unites
with any particular acid to the exclusion of all others, or vice versa,
but that all possible combinations are formed, to at least some extent,
of the various basic and acid ions present in solution. For example:
Suppose we have calcium carbonate in solution. It partly dissociates
into the positive and negative ions Ca and CO, as follows:

C100) =) =F eo,
Again, if magnesium sulphate is in solution it partly dissociates as
follows:

MgSO, ug + S0,

Now, if these two solutions are poured into each other, part of the
calcium and sulphuric acid ions unite to form calcium ‘sulphate, as

follows:

“a + 50, — _ CaSO,

HOT SPRINGS, ARKANSAS. 13

and part of the magnesium and carbonic acid ions unite to form mag-
nesium carbonate, as follows:

4 SS

so that we have in solution not only the calcium carbonate, magnesium
sulphate, and magnesium, calcium, carbonic acid, and sulphuric acid
ions with which we started, but also some calcium sulphate and mag- °
nesium carbonate.

In calculating the above-mentioned hypothetical combination, sodium
is joined to the nitrous and nitric acid tons; potassium to iodine and
bromine; calcium to the phosphoric-acid ion and sodium to the metaboric-
acid ion. Chlorine is assigned to the bases in the order NH,, Li, K,
Na; sulphuric-acid ion in the order NH,, Li, K, Na, Mg, Ca, and the
residual bases are joined to bicarbonic-acid ion in the order Na, Mg,
Ca, Mn, Fe. In case the bicarbonic-acid ion is not present in large
enough amounts to join with all the remaining bases, the residual cal-
cium is joined to silica to form calcium silicate, and manganese and iron
are calculated as Mn,O, and Fe,O,, respectively.

METHODS OF EXAMINATION.

TEMPERATURE.—The temperature of each spring was taken with an
accurately standardized maximum thermometer on the date of the
sanitary analysis of the water. Finally, the temperatures of all of the
springs were taken in one day. It will be noticed that these tempera-
tures sometimes vary quite a few degrees for the same spring. This
seems to be due to two causes. In the first place the temperature of
the spring as it issues from the earth varies slightly from time to time;
secondly, the springs sometimes have quite large basins, so that we can
not get the temperature just as the water issues from the earth, but
must take it as influenced by a comparatively large body of water,
which in turn has been cooled to some extent by standing in the air.
When these springs have recently been drained the temperature is
nearly the same as where they issue from the earth, but when the basin
is full the temperature is quite a few degrees lower.

Fitow.—The flow of each spring was measured by observing the
length of time taken to fill a vessel of known capacity from a pipe that
drained the spring in question. In some cases such determinations
could not be made, so the flow of the springs was estimated by com-
paring them with other springs of known flow. Such estimations
were made by the head waterman of the reservation, Mr. Ed Hardin,
who by long experience had arrived at such a point that he could come
very near the correct figure.

HypROGEN SULPHIDE.—The test for the presence of hydrogen sul-
phide was made both by boiling a sample of water and noticing the
smell, and by passing the vapors over a piece of lead acetate paper.
In a few cases, as a check, an actual determination of the hydrogen
sulphide by the method given in Sutton’s Volumetric Analysis was
made. This is as follows:

About 0.5 ¢. ¢. of = iodine was measured into a 500 c. c. flask and
the water under examination run in till the color of the iodine disap-
peared. Fivec.c. of starch water was added and i iodine run in till

the blue color appeared. The flask was then filled to the mark with

14 HOT SPRINGS, ARKANSAS.

distilled water. The amount of water actually titrated was found by
substracting the sum of iodine, starch solution, and distilled water
from 500 c.c. Asan excess of iodine solution was required to produce
the blue color a correction was applied by making 5 ce. ec. of starch solu-

tion up to 500 c. c. with distilled water and adding = iodine until the

color of the solution was just as blue as that in the actual determina-

tion. This figure substracted from the first figure would give the
Tees he ;

number of ¢. ¢. of 75 iodine used by the hydrogen sulphide. In every

case tried the correction was just equal to the original figure, and in
neither of the other tests was hydrogen sulphide found to be present in
any of the springs.

NITROGEN AND OXYGEN were determined by making use of the
Tiemann and Preusse modification of Reichhardt’s apparatus, the des-
cription of which is here taken from Hempel’s Gas Analysis (trans-
lated by L. M. Dennis, Cornell University):

This consists of two flasks A and B (Fig. I) each of about 1 liter capacity and con-
nected by tubes with the gas collector C. The flask A is fitted with a perforated rubber
stopper in which is inserted the glass tube a bent at a right angle and ending flush with
the lower surface of the stopper; «@ is joined by a piece of rubber tubing to the tube
bc, which in turn connects with the gas collector C. C is held by a clamp, has a dia-
meter of 30 mm., is about 560 mm. long, and at the upper end is drawn out to a short,
narrow tube, which can be closed with the rubber tube and pinchcock g. In the
lower end of OC is a rubber stopper with two holes through one of which the tube bc,
projecting about 280 mm. into C, isinserted. Through the other opening passes the
tube d, which extends only slightly beyond the stopper and connects C with the flask
B. 5B has a double bore rubber stopper carrying the tubes e, and f; e ends about 10
mm. above the bottom of the flask and above the stopper it is bent at a right angle
and is connected with d. The tube f, which need not project below the stopper, car-
ries a thin rubber tube X about 1 meter in length and provided with a mouthpiece.
A pincheock for closing the rubber between a and b is also needed.

The apparatus thus arranged is made ready for a determination by filling the flask
B somewhat more than half full of boiled, distilled water and removing the flask
A by slipping the tube a out of the rubber connection; then by blowing into the
rubber tube X, water is driven over from the flask B into the gas collector C and the
adjoining tubes until the air is wholly displaced. The rubber tubes at 6 and g are
now closed with pinchcocks. The flask A is then filled to the brim with distilled
water, the stopper is inserted, water being thereby driven into the tube a and the
flask is again connected with b, the pinchcock being opened.

The water in B is now heated to gentle boiling, and that in A is allowed to boil
somewhat more rapidly. The absorbed air is thus driven out and the gases dis-
solved in the water which is in A and C collect in the upper part of C from which
they are removed by occasionally opening the pinchcock at g and blowing into the
rubber tube X.

When upon cooling the apparatus, the gases which have collected disappear, the
heating of the flask A is discontinued, the pinchcock between a and b is closed and
A is disconnected and emptied. The water in C and B is now entirely free from
absorbed gases and air can not enter from without, because the liquid in B is kept
continually boiling. The apparatus is now ready for a determination, which is made
as follows: The cooled flask A, whose capacity has been previously determined, is
filled with the water to be examined and the stopper is pressed in so far that the air
in the tube a is completely driven out. ais then connected with b, care being taken
that in so doing no air bubbles are inclosed. The pinchcock between a and b is
opened and the water in A is heated to gentle boiling. The dissolved gases are
hereby driven over into the gas collector C. Steam is formed at the sametime. The
heating of the flask A must be so regulated that the gas and steam evolved never
drive out more than half the liquid in C, otherwise there is danger of gas bubbles
entering the tubes d and e and thus escaping.

After heating for about twenty minutes the flame under A is removed. Ina few
minutes the steam in A and C condenses, and water passes from B to Cand A. If
a gas bubble is observed in A which will not disappear when the neck of A is cooled

by applying a wet towel two or three times, the flask A must again be heated and
cooled in the manner just described. The operation is ended when the hot liquid
flows back and completely fills A.2. Therubber tube g is then connected with a small
piece of thermometer tube which is filled with water, and the gas standing over the
hot liquid in C is driven over into a modified Winkler gas burette by blowing into
the tube X and opening the pinchcock g.

The gases in the burette were allowed to cool for about ten minutes,
and then passed into a simple absorption pipette filled with potassium-
hydrate solution (one part KO H to two parts of water). The pipette
was shaken two or three times to absorb the carbon dioxide, and the
residual gases passed back into the burette. The burette was allowed

to stand for a few minutes and the volume of the gas read off. This
gave the volume of oxygen+the volume of nitrogen. The gas was
then passed into a double-absorption pipette filled with potassium
pyrogallate, prepared by mixing 5 grams pyrogallic acid and 15 ce
of water with 120 grams of potassium hydroxide and 80 cc of water.

“Tt has been observed in waters rich in bicarbonates that it is nearly impossible to
drive oif all the CO, by this means, but the O and N and part of the CO, are driven
off in the course of a half.hour’s boiling. Therefore the author did not continue
poring A, even though a small bubble of gas were present, more than one-half an
our.

16 HOT SPRINGS, ARKANSAS.

After being shaken with this solution for about four minutes the gas
was passed back into the burette, the burette allowed to stand fora

few minutes, and the reading taken. The last reading gave the num-
ber of ce of nitrogen present, and the difference between the first and

last reading, the number of cc of oxygen. A temperature and baro-~

metric pressure reading were also taken, to correct the gas volume to
0° Cand 760 mm. pressure. Numerous pr ecautions as to temperature,
saturation of reagents, etc., not mentioned in the above brief sketch
were taken, all of which can be found in any standard work on gas
analysis.

CARBON DIOXIDE.—(In excess of that necessary to form normal car-
bonates.) The determination of the carbon dioxide existing in water
in excess of that present as normal carbonates was made by a method
given in Sutton’s Volumetric Analysis and designed by Pettenkofer.
One hundred ce of the water was treated in a flask with 3 cc of a
saturated solution of calcium chloride, 2 ce of a saturated solution of
ammonium chloride, and 45 ce of a saturated solution of calcium
hydroxide, whose strength had previously been determined in terms of

n ‘ 3 ; ‘ apie
10 hydrochloric acid, using lacmoid as indicator. The flask was

stoppered, the solution well mixed, and the whole set aside for twelve
hours to allow the calcium carbonate to settle. At the end of this
time x ) ce of the clear solution was drawn off in a pipette and titrated

with +5 ) hy drochloric acid, using lacmoid as indicator. This result

was cantatas by three and subtracted from the amount of =, hydro-

n
10
ehloric acid necessary to neutralize 45 ce of the calcium hydroxide
solution, thus giving the amount of calcium hydr cae solution that had

been acted on by the carbon dioxide in terms of = acid. Multiply-

ing the number of ce so found by 0.0022, the weight of carbon dioxide
in 100 ce above that necessar y to form normal carbonates was found.
Dividing the weight so found by the weight of 1 cc of carbon dioxide
at 0° C and 760 mm. pressure and multiplying the result by 10, the
number of cc of carbon dioxide in a liter in excess of that necessary
to form normal carbonates was given.

CARBON DIOXIDE.—(Given off from the bicarbonates when they are
evaporated to dryness.) In making this determination the method of
Cameron®* for the ‘‘ Estimation of carbonates and bicarbonates in
aqueous solution” was used. By this method the amount of bicarbonic
acid ion (HCO,) was determined, and from this we could easily estimate
how much of the bicarbonic acid would remain as the normal carbon-
ate and how much be given oft as carbon dioxide. The method is as
follows:

To one hundred ce of the water was first added a few drops of
phenolphthalein. In case there were alkali carbonates present the
usual red color would be evident. The solution was now titrated with
a solution of HKSO,, containing 6.758 grams to the liter, adding the
HKSO, solution at the rate of a drop every two or three seconds,
until the red color had completely disappeared. The reading on the

“Report 64 U. 8. Department of Agriculture; American Chemical Journal. 23,471

a

HOT SPRINGS, ARKANSAS. iG

burette was recorded, and to the clear solution was added one drop of
methylorange. A pure yellow color resulted. The titration was con-
tinued with the HKSO, without refilling the burette until the change toa
very slightly darker and reddish color was noted. ‘The change was S faint
and required practice to detect. The reading at this point was also
recorded.

The first reading recorded gives the amount of alkali carbonates
present and must be multiplied by the factor 0.002979 for the result in
grams of CO, ions.

For the number of grams of HCO, ions present the first recorded
reading is multiplied by two and the result subtracted from the second
reading, and this remainder is multiplied by the factor 0.003028. In
no case were carbonates found in any of the springs by the above
method, but only bicarbonates.

Having now obtained the weight of HCO, ions in 1,000 ce of water,
we next calculate the weight of CO, given off when a like volume is
evaporated to dryness, and dividing this result by the weight of one
ee of carbon dioxide at 0° C. and 760mm. pressure the number of ce
of carbon dioxide given off from the bicarbonates is the result. Sub-
tracting the number of ce of carbon dioxide given off from the
bicarbonates from the number of cc of carbon dioxide in excess of
that necessary to form normal carbonates, we have left the number of
ec existing in solution in a free state.

Bicarponic acrp.—The amount of this substance present in the
spring was estimated during the process of determining the amount of
carbon dioxide given off from bicarbonates in the par agraph above.

It will be noticed in several of the analyses of the different springs
that the amount of carbon dioxide (set free from bicarbonates on
evaporating to dryness) and calculated from the bicarbonic acid does
not agree with the amount of bicarbonic acid found in solution. This
is because the samples for determining the carbon dioxide and bicar-
bonic acid were taken at widely different periods, and the amount of
bicarbonic acid had evidently changed somewhat during the interven-
ing time. ‘This is easily explained when we remember that many of
the springs are supplied from two or three different spring heads,
which doubtless vary from time to time both in their amount of flow
and in the amount of bicarbonic acid held in solution.

For the determination of nitric and nitrous acid, free and albumi-
noid ammonia, and oxygen consuming capacity the methods as given
in Mason’s Examination of Water were followed in all their principal
details. They are as follows:

Nrrreic actp.—In determining nitric acid, 100. c. of the spring water
was treated with 2 drops of a saturated solution of sodium carbonate
and evaporated to dryness on the water bath. The residue was treated
with 2 ¢. c. of phenol sulphonic acid (made by mixing 148 ¢. ¢. of pure
sulphuric acid, 12 c. c. of water, and 24 grams of phenol), a littlewwater
added, and then an excess of ammonia. The solution was transferred
to a 100 ¢. c. Nessler jar, the volume made up to 100 c¢. ¢. with distilled
water, and the depth of tne yellow color compared with that produced
by treating different measured amounts of standard potassium nitrate
(containing 0.01 milligram of nitrogen as nitrate in each ec. c.) in the
same manner.

Nirrous acip.—For this determination 100 c¢.c. of the water was
placed in a 100 c. c. Nessler jar and treated with 1 drop of concen-

S. Doc. 282

18 HOT SPRINGS, ARKANSAS.

trated hydrochloric acid. One ec. c. of sulphanilic acid (containing 1
gram in each 100 ec. ¢. of water) was then added, followed by 1 ¢. ¢. of a
solution of napthylamine hydrochloride (obtained by poine 0.5 grams
of the salt with 100 ¢. c. of water for ten minutes at constant volume),
and the whole well mixed. The Nessler jar was then set aside for half
an hour, along with several other Nessler jars containing known amounts
of astandard nitrite solution (containing 0.0001 milligram of nitrogen as
nitrite in each c. ¢.), made up to 100 ¢. c. with nitrite-free water, and
treated with hydrochloric acid, sulphanilic acid, and napthy lamine
hydrochloride in the manner just described. By comparing the depth
of pink color in the known and unknown solutions the amount of
nitrite could be determined.

FREE AMMONIA.—A large flask of about 13-liter capacity was con-
nected to an upright bulbed condenser by means of a rather large glass
tube and soft, new, rubber-stopper connections. In this was placed 5
c.c. of asaturated solution of sodium carbonate and 200 c. ¢. of ammonia-
free water. The water was distilled off in 50 ¢. c. Nessler jars until ao
more ammonia was shown, when the jars were nesslerized. Five hun-
dred c. c. of the water under examination was now added and the dis-
tillation in 50 c. c. Nessler jars continued till ammonia ceased to be
given off. About four or five jars were usually necessary. These jars
were nesslerized and the depth of color compared with that in other
jars which contained known amounts of a standard ammonium chloride
solution (containing 0.01 milligram of NH, in each c. ¢.), made up to 50
c. c. with ammonia-free water and nesslerized in the same manner.

ToTaL AMMONIA.—The same upparatus was used as that mentioned
in the paragraph above. In it were placed 200 c. ¢. of distilled water
and 50 c. c. of alkaline permanganate solution (prepared by dissolving
200 grams of potassium hydroxide and 8 grams of potassium perman-
ganate in 1,250 c. e. of water and boiling the whole down to about 1
liter). The water was distilled off in 50 c. c. Nessler jars till ammonia
ceased tocomeover. Five hundred c. c. of water under examination was
now added and the distillation continued till ammonia ceased to come off.
Six jars were in all casessufficient. These jars were nesslerized and com-
pared with nesslerized jars of knownstrength justas in the determination
of freeammonia. From the total ammonia thus found subtract the free
ammonia and the result is the albuminoid ammonia in 500. c. of water.

Many precautionary details of the two above methods are not given,
but can be found by consulting any good book on water analysis.

OxYGEN-CONSUMING CAPACITY.—In making this determination two
solutions were first prepared: (1) A standard solution of potassium
permanganate containing 0.3952 gram to the liter, each c. c. of which
has 0.1 milligram of oxygen ay: ailable for oxydation; and (2) a stand-
ard solution of oxalic acid containing 0.7875 gram of crystalized oxalic
acid to the liter. The value of the oxalic acid in terms of the perman-

ganaté was determined by boiling 10 c. ¢. of oxalic-acid solution and 200
c.c. of distilled water with 10 e. c. of sulphuric acid (1-8) and titrating
the fluid while boiling with the standard permanganate aaa to the
appearance of a pink color. In the actual determination 200 ¢.c. of
the water in a porcelain dish was treated with 10 c. c. of sulphuric acid
(1-3) and the whole brought to the boiling point. Standard perman-

ganate was run in until the water was quite red and the boiling con-
Paige for ten minutes, adding permanganate every now and then to
keep the pink color about the same. The boiling was now stopped,

+ ttremebide

10 ec. ¢. of oxalic acid run in, which destroyed the color, and the solution
titrated with the standard permanganate to the appearance of a pink
color. From the total number of ¢. ¢. of permanganate used was sub-
tracted the number of ¢. c. equal to 10 c. ¢. of oxalic acid. The result
gives the number of c. c. of permanganate required for 200 ¢. ¢. of
water.

ToraL souips.—Measured amounts of the water were evaporated to
dryness in weighed platinum dishes on the steam bath. The dishes
were dried for twelve hours at the temperature of boiling water, cooled
in the desiccator, and weighed. The increase in weight of the dish
gives the amount of solids present in the volume of water used.

To determine chlorine, iron and aluminum, manganese, bromine,
iodine, arsenic, and boric acid large quantities of the water were evap-
orated to dryness after the addition of a small amount of sodium car-
bonate. The residue thus obtained was boiled with distilled water,
transferred to a filter and thoroughly washed with hot water. The
residue in the paper was dried and transferred to the dish in which the
evaporation was made, the paper burned and added, and the whole
kept for the determination of iron, aluminum, and manganese. The
filtrate was made to a definite volume and aliquot portions taken to
determine the constituents mentioned above other than iron, aluminum,
and manganese.

CHLORINE.—An aliquot portion from the above filitrate was treated
with a few drops of phenolphthalein and = HKSO, added at the rate
of a drop every few seconds until the red color had entirely disap-
peared, thus showing that all of the carbonates had changed to bicar-
bonates.* A few drops of potassium chromate indicator were then
added and the chlorides titrated with a solution of silver nitrate each
ec. c. of which would precipitate 1 milligram of chlorine.

IODINE AND BROMINE.—The qualitative tests for the presence of iodine
and bromine were very much the same as those used in Fresenius.
Another aliquot portion from the above filtrate was evaporated to dry-
ness on the steam bath. Twoor 3 ¢.c. of water were added to dissolve
and soften up the residue and enough absolute alcohol added to bring
the percentage of alcohol down to about 90 per cent. This was boiled
and filtered and the treatment with 90 per cent alcohol repeated once
or twice. Two or 3 drops of sodium hydrate solution were added to
the filtrate and it was evaporated to dryness. The same process of
extracting with 90 per cent alcohol was repeated on the new residue
and the extract filtered off from the undissolved portion. A drop of
sodium hydrate was added to the filtrate and it was evaporated to dry-
ness. ‘The residue was treated with a little distilled water, dilute sul-
phuric acid added to acid reaction, the liquid transferred to a test tube,
and a little carbon disulphide added. Three or 4 drops of potassium
nitrite solution were then added and the test tube shaken. The pres-
ence of iodine was shown by a pink color in the carbon bisulphide.
Chlorine water was then added until the pink color due to the iodine
had disappeared, then a little more chlorine water.

The presence of bromine was shown by an orange color in the car-
bon bisulphide.

In no case did a sample of spring water give nearly as distinct a reac-

tion for iodine and bromine as did a known sample of water containing
0.2 milligram of both iodine and bromine, as iodides and bromides, to
the liter.

An attempt was made to determine iodine and bromine quantita-
tively in spring No. 15 by evaporating down a large volume of
water, but the attempt failed because both these elements were pres-
ent in such minute traces. The method used was the same as that
described by Gooch and Whitfieid* and is as follows: The iodides and
bromides were extracted with 90 per cent alcohol in the same manner
as described above.

The alcohol extract was evaporated to dryness, acidulated with dilute
sulphuric acid, mixed with a ferric sulphate solution, and distilled
from a retort which was joined to a condenser sealed by a U-tube filled
with water and carbon bisulphide. If a very small amount of iodine
had been present it would have colored the carbon bisulphide and
could have been titrated with sodium thiosulphate, but not enough
was present.

After the distillation had been continued long enough to be sure
that all iodine had been volatilized, crystals of potassium permanga-
nate were added and the distillation continued the same as before,

except that the U-tube acting as a seal was now filled with water and
chloroform. The contents of the tube were treated with sodium
hydroxide and zine in a breaker and the chloride and bromide solution
so formed acidified with nitric acid and precipitated with silver nitrate.
The precipitate was dried and weighed. — It was then dissolved in potas-
sium cyanide and the silver precipitated by electrolysis.” In this way
data on the weight of the combined silver chloride and bromide and
the weight of the silver in same was determined. From this the weight
of the bromine could be calculated, which in this case was nothing.

ARSENIC actp.—An aliquot portion of the above filtrate was acidified
with hydrochloric acid, the solution heated to 70° C., and a current
of hydrogen sulphide passed through for several hours. In case either
arsenic, copper, or lead were present they would be precipitated. No
precipitation took place in any of the springs.

Boric actp.—A test for boric acid was made in the following manner:
A part of the above filtrate was evaporated to dryness, treated with
a cubic centimeter or two of water and slightly acidified with hydro-
chloric acid. About 25 or 30 ¢. ¢. of absolute aleohol was added, the
solution boiled and filtered. This was repeated. The filtrate was
made slightly alkaline with sodium hydrate and evaporated to dry-
ness. A very little water was added, the solution slightly acidified
with hydrochloric acid, and a strip of tumeric paper placed in the
liquid. The whole was evaporated to dryness on the steam bath, and
the heating continued until the tumeric paper had become entirely dry.
In ease boric acid were e present the tumeric paper took on a cherry-
red color.

A quantitative determination of boric acid was made in the case of
two springs to serve as an example of all the other springs.

The method used was the same as that described by Gooch,° except
that a slightly different form of apparatus was used.

The apparatus used by the author (Fig. II) consisted of a round-
bottomed flask with a constricted neck joined to an upright bulbed
condenser by means of a glass tube slightly sloping toward the flask
instead of being bent at right angles. The flask was heated by being
immersed in a paraffin bath, and the distillate was received in a small
flask joined to the condenser by means of a grooved cork. The method
was as follows:

An aliquot portion of the above filtrate evaporated to dryness, was
slightly acidified with acetic acid and transferred to the round-bottomed

flask, 10 ¢. c. of methy]! aleohol was added, the flask lowered in the par-
aftin bath, and distilled to dryness at a temperature of 130° C. to 140°C.,
collecting the distillate in the flask attached to the condenser with a
grooved stopper. The paraftin bath was lowered, the flask allowed to
cool, and 10 ¢. c. more of methyl alcohol added. This was then dis-
tilled over and the same process repeated six times, except that after the
fourth time a couple of drops of acetic acid were added. A large plati-
num crucible now received about | gram of quicklime and was blasted
until it ceased to lose weight. The constant weight was recorded and
the distillate transferred to the crucible. The alcoholic solution of

boric acid and the quicklime were stirred together for about fifteen
minutes with a platinum rod to be sure that all boric acid was fixed.

The volatile contents of the crucible were now evaporated off at a
low temperature. It was found necessary to grease the edges of the
crucible with vaseline to keep the solution from crawling over. After
the contents of the crucible had been evaporated to dryness the cruci-
ble was fully dried in the air bath and finally blasted. The increase
in weight of the crucible gives the weight of boric anhydride (B,O,)
present.

TRON, ALUMINUM, AND MANGANESE.—The residue spoken of previ-
ously that was reserved for the determination of ir on, aluminum, and
manganese was treated with hydrochloric acid and evaporated to “dry -
ness. It was thoroughly dried at about 120° C., again taken up a
water and hydroc -hloric acid and filtered. The filtrate was evaporated
to dryness and dried at 120°C. It was then taken up with hydrochloric
acid and water and filtered again. This filtrate was heated to the
boiling temperature, and ammonia added, a drop at a time, until it could
be very faintly smelled coming off from the solution. The solution
was then filtered and the pr ecipitate well washed with hot water, burned
and weighed as Fe,O, and Al,O, in the ordinary manner.

The ammoniacal filtrate from above was treated with a few drops of
bromine, more ammonia was then added, and the whole boiled after
stirring up. The vessel was removed from the source of heat, cooled
a little, and a little more bromine and ammonia added. This process
repeated once or twice precipiated all the manganese as the oxide.
The solution was made slightly acid with acetic acid, filtered and
washed at once with hot water. The filter and contents were burned
and weighed as Mn,O,. This is the method by which the iron,
aluminum, and manganese were determined in springs 24 to 46, inclu-
sive. In the first 23 springs these three elements were determined in
the same portion that was used for the estimation of calcium and
magnesium.

Srirca.—In this determination a large quantity of water was evapor-
ated to dryness in platinum with the occasional addition of small
amounts of hydrochloric acid. Afterall the water had been evaporated
to dryness, the dish and contents were completely dried at 120° C.
The residue was taken up with hydrochloric acid and water, heated
and filtered, washing the residue thoroughly with hot water. This
process took out most of the silica. The filtrate was then evaporated
to dryness, dried thoroughly at 120° C., again taken up in hydro-
chlorie acid solution by heat, and filtered. The filtrate was made to a
definite volume, aliquot portions of which were used for the determina-
tions of calcium, magnesium, sulphuric acid, potassium, sodium, lith-
ium, and phosphoric acid. ‘The two residues were transferred to a
crucible, burned and blasted in the ordinar y way. and finally weighed
as silica.

CALCIUM AND MAGNESIUM.—An aliquot portion of the above filtrate
was first treated with ammonia and filtered, then treated with ammonia
and bromine water and filtered, and finally treated with ammonium
oxalate in the usual manner. This was allowed to stand over night,
the liquid filtered off, and the precipitate dissolved in hydrochlori¢
acid and reprecipitated with ammonia and a little extra ammonium
oxalate. This was allowed to stand over night and filtered and washed
on the same paper previously used. The precipate was dried, trans-

ferred to a crucible, burned and blasted in the ordinary way, and
finally weighed as calcium oxide. The combined filtrates were eyapo-
rated to dryness in platinum and the major part of the ammonium
salts driven off by the aidof heat. The residue was dissolved in dilute
hydrochloric acid and filtered. The filtrate was made slightly ammo-
niacal, enough sodium phosphate solucion added, a drop ‘at a time, to
precipitate all magnesium, and 10 ce. of concentrated ammonia finally
added, drop by drop. The beaker was covered and allowed to stand
over night, filtered, washed with dilute ammonia water, dried, blasted,
and weighed as magnesium pyrophosphate.

SULPHURIC ACID, POTASSIUM, SODIUM, AND LITHIUM.—Another por-
tion of the above filtrate was precipitated while boiling with hot, dilute
barium chloride, and after standing filtered from the precipitated
barium sulphate, which was washed, dried, burned, and finally weighed
in the ordinary way.

The filtrate was evaporated to dryness and taken up with water.
This solution was precipitated with a solution of barium hydrate and
filtered off from the insoluble magnesium hydrate. The magnesiurh
hydrate precipitate was well washed and the combined filtrate and
washings treated with ammonia, ammonium carbonate, and a little
ammonium oxalate to precipitate barium and calcium. This precipi-
tate was allowed to stand over night, filtered off and well washed.
The filtrate and washings were evaporated to dryness on the steam
bath, dried, and all of the ammonium salts driven off by gentle heat.
The residue was taken up with water, filtered through a small filter,
using as little wash water as possible, evaporated to a small volume,
and finally again precipitated with a drop of ammonia and two to
three drops of ammonium carbonate and oxalate. If any precipitate
appeared, which was not usually the case, it was filtered off and the
same process repeated. In any case, the solution was filtered from the
magnesium hydrate that had precipitated out on concentrating the
solution. The yee was then evaporated to dryness and all ammo-
nium salts driven off by heating in platinum to a little below redness.
The residue was taken up with a little water and filtered through a
small filter, again using as little wash water as possible, and again
heated in a to a point slightly below red heat. By this time
all of the magnesia should have been removed. The residue was
then taken up with a little water, filtered into a weighed platinum dish,
treated with a few drops of hydrochloric acid, and evaporated to dry-
ness. This residue was thoroughly dried, heated to a little below
redness, cooled in a desiccator, and finally weighed as the combined
chlorides of potassium, sodium, and lithium.

The determination of lithium was then made accor ding to the method
of Gooch*—i. e., the combined chlorides were dissolved in water and
transferred to a small beaker, where they were again evaporated nearly
to dryness. About 30 cc. of amyl alcohol was added and the contents
of the beaker boiled until the temperature had risen to approximately
the boiling point of the amy] alcohol, showing that all of the water had
been driven off. The liquid was cooled slightly , and a drop of hydro-
chloric acid was added to reconvert small amounts of lithium hydrate
to lithium chloride. The boiling was then continued to again drive off
all water, until finally the liquid had reached a volume of about 15 cc.

94 — HOT SPRINGS, ARKANSAS.

The amyl] alcohol was then filtered off in a weighed platinum dish and
the filter washed with a little amy! alcohol that was also allowed to iun
into the dish. The amy] alcohol was driven off from the filter and beaker
in the air bath and these two kept for the determinations of potassium
and sodium. The contents of the platinum dish were evaporated to
dryness, treated with a little dilute sulphuric acid, and finally burned
and weighed. This gave the weight of the lithium sulphate, from
which was subtracted 0.0017 gram to correct for the solubility of the
_sodium and potassium chlorides in the amyl alcohol. The residue was
finally tested with the spectroscope for the lithium line. In every case
the lithium line was found, but in no case was any lithium sulphate
left after applying the correction of 0.0017 gram. The lithium was
therefore reported as traces.

The contents of the beaker and filter from which the amyl alcohol
had been driven were then used for the determination of potassium
and sodium. The contents of the beaker were dissolved in hot water
and passed through the filter, which was thoroughly washed. The
combined filtrate and washings were transferred to a porcelain dish,
treated with platinum chloride solution, and evaporated nearly to dry-
ness. The residue was treated with 80 per cent alcohol and thoroughly
washed on the filter with this medium until all platinum chloride had
been washed out. The filter paper was dried at the temperature of
boiling water, and the residue dissolved in water and passed into a
weighed platinum dish from which the water was evaporated off, the
dish and contents dried at the temperature of boiling water, and finally
weighed as potassium platinic chloride. An addition of 6.0008 gram
of potassium chloride to the weight of this substance found is necessary.

The weight of the sodium chloride is found by subtracting the com-
bined weights of the lithium chloride (in this case nothing) and the
potassium chloride (corrected) from the total weight of the three
chlorides.

Of course, if the amyl! alcohol in the determination of lithium above
is not evaporated to exactly 15 cc., the corrections will be different from
those mentioned above.*

PuospHoric Aactp.—A third aliquot portion from the filtrate men-
tioned above was treated with about 10 ce. (con.) nitric acid and evap-
orated in a porcelain dish nearly to dryness to drive off hydrochloric
acid. The residue was taken up with water and if necessary filtered.
Ammonia was added to alkalinity and then nitric acid to just bring
back to acidity. Some ammonium nitrate was added and the beaker
heated in the water bath to 45- to 50° C. Molybdate solution was
then added and the solution kept at a temperature of 45° to 50° C. for
half an hour. The yellow precipitate formed at this point appeared
in most cases only in traces, but in a few cases it was filtered off and
washed with cold water till it was entirely free of nitric and molybdic
acids. The precipitate and filter were then transferred to a beaker,
a little water added, and the paper and contents thoroughly beaten
into a pulp. The yellow precipitate was then dissolved by the addi-
tion of a small amount of standard potassium hydroxide solution
(1c. ¢c.=1 milligram of P,O,); phenolphthalein was added and the
solution titrated with standard nitric acid solution of exactly the same
strength as the alkaline solution. From the data so obtained the

amount of phosphoric acid ion in the water can be calculated.* For the

determination of fluorine the same method was used as described by

Gooch and Whitfield.” For the determination of barium and stron-

tium a combination of Gooch and Whitfield’s method along with another
was employed. They are briefly as follows:

Fruorme.—A large quantity of water was evaporated to dryness
and filtered off from the residue which was washed on the filter. The
filter and contents were dried, the contents placed aside and the filter
burned and the ash added to the contents. The whole was now trans-
ferred to a flask, which was so arranged as to allow a current of air to
pass through any liquid that might be in the bottom, and from there
into an attached u-tube, partly filled with dilute ammonia. Concen-
trated sulphuric acid was added to the contents of the flask, and a
current of dry air passed through the liquid, and from there into the
U-tube. The flask was heated to 150° C. If any considerable amount
of fluorine had been present it should have been volatilized as silican
tetra fluoride and then decomposed by the dilute ammonia in the u-tube,
depositing silica in so doing. No silica appeared at this point in the
spring examined. The contents of the U-tube was removed and treated
with zinc oxide dissolved in ammonia, evaporated till ammonia ceased
to come off and filtered. The filtrate was treated with calcium chloride,
followed by sodium carbonate in boiling solution, filtered and washed.
The residue was ignited and extracted with acetic acid. Operating
in this way no residue of caleium fluoride was found.

BaRIUM AND sTRoNTIUM.—The residue left in the flask from the
above determination was transferred to platium, treated with enough
hydrofluoric acid to volatilize all silica and with some sulphuric acid
and evaporated to dryness. This treatment was repeated. ‘The residue

was fused with sodium carbonate, treated with water and a few drops
of alcohol, filtered, and washed. The contents of the filter was digested
with hot dilute acetic acid to dissolve barium, strontium, magnesium,
and calcium carbonates and filtered. ‘he filtrate was then nearly
neutralized with ammonia and about fifty times the weight of the com-
bined sulphates in ammonium sulphate was added, which ammonium
sulphate was dissolved.in four times its weight of water. The whole
was allowed to stand over night. In case barium or strontium were
present they would be precipitated here as the sulphates. Only a
slight nonweighable opalescence appeared, however, in the spring
examined. For the sake of completeness, and to be ‘able to test the
final residue with the spectroscope, the process was carried on just as
inan actual determination. The precipitated sulphates were filtered and
washed with a ccncentrated solution of ammonium sulphate, till no
more calcium was present in the wash water, as shown by the ammo-
nium oxalate test. The filter was ignited and the residue evaporated to
dryness with a drop or two of sulphuric acid. The combined sul-
phates so obtained from a very large quantity of water did not weigh
over 0.5 milligram, and most of “this was caleium sulphate. The
extremely small residue was fused with sodium carbonate, treated with
avery small quantity of water, and filtered on a very small filter paper,
washing only once. Dilute hydrochloric acid was now passed through

the filter and the filtrate containing any barium and strontium as the
chlorides was collected in a platinum dish and evaporated to dryness.
The minute residue was tested by the spectroscope for the barium and
strontium lines, both of which were faintly seen.

Srrontrum.—This substance was determined in a separate portion.
The oxide of calcium, which had been obtained by blasting the
ammonium oxalate precipitate in the determination of calcium, was
transferred to a small flask and dissolved in concentrated nitric acid.
The acid was entirely evaporated off by means of a current of air and
heating in a paraffin bath to 135° C. The flask and contents were
dried at 140° C., and the completely dried nitrates were treated with
the least possible quantity of a mixture of equal parts of absolute
aleohoi and ether, necessary to dissolve the calcium nitrate. The
flask was corked, allowed to stand over night, and the insoluble resi-
due, if any, filtered off on the smallest possible filter and washed with
the ether-alcohol mixture. ‘The strontium nitrate on the filter was
washed with water into a platinum dish and evaporated to dryness.
The dish was blasted to change the nitrate to the oxide. No increase
in the weight of the dish was noticed, yet upon treating the contents
of the dish with a little hydrochloric acid, evaporating nearly to dry-
ness and testing with the spectroscope, the strontium lines were seen.

THE MEDICINAL VALUE OF THE VARIOUS SALTS AND GASES USUALLY
PRESENT IN MINERAL WATERS.

CARBONATES AND BICARBONATES. —One of the most important groups
of mineral waters are the alkaline waters, which are characterized by the
presence, in predominating quantities, of one or more of the alkaline or
alkaline earth carbonates or bicarbonates. These are the carbonates or
bicarbonates of sodium, potassium, lithium, calcium, and magnesium.
In case iron is present in large quantities as the bicarbonate we have a
water belonging to the chalybeate class. Since these waters are alkaline -
they are excellent remedies in cases of sour stomach and in sick headaches
which arise from acid dyspepsia. They act very markedly on the
mucous membranes, increasing the flow of the gastric juice and other
digestive fluids and are consequently of use in many cases of indiges-
tion. In conjunction with the sulphated salines they give excellent
results when used in the treatment of catarrhal conditions of the
stomach and intestines. Such waters correct acidity of the urine,
markedly increase the flow of urine and help to dissolve uric acid
deposits. They are therefore of value 1 in cases of rheumatism, gout,
diabetes, ete.

Sodium carbonate and bicarbonate.—Sodium carbonate or bicarbo-
nate appears as a normal constituent of the blood, lymph, and nearly
all secretions of the mucous membrane. Where conditions arise that
eause these fluids to become acid, waters containing carbonate or
bicarbonate of soda are of value in counteracting the effect. Waters
containing either of these substances have been used with excellent
effect in the treatment of acid dyspepsia, diabetes, where sugar has
been caused to disappear from the urine by their use, and in breaking
up and eliminating deposits of uric acid and uric acid sand and gravel.

Potassium carbonate and bicarbonate.—Both of these salts are readily
soluble in water. The bicarbonate is the one usually present in
mineral waters. The properties of this salt are very much the same

HOT SPRINGS, ARKANSAS. mal
as those of sodium bicarbonate. It increases the flow of urine and
corrects acidity of the bodily fluids. Its chief use is in-the treatment
of stone in the bladder.

Lithium carbonate and bicarbonate.—Lithium carbonate is very
sparingly soluble in water, while the bicarbonate is quite soluble.
It is in the latter form that lithium is most often reported in mineral
waters. This compound is most frequently used in cases of rheuma-
tism and gout, where it forms a very soluble urate which is easily
eliminated from the system. In cases of gravel and calculi it is a very
valuable disintegrating agent.

Magnesium carbonate and bicarbonate.—These two substances are
mild laxatives and are perhaps the best of all the carbonates and
biearbonates in correcting an acid condition of the stomach and curing
sick headache caused by constipation. They are valuable agents in
breaking up deposits in the bladder.

Calcium carbonate and bicarbonate.—Calcium is usually present in
waters as the bicarbonate. Both of these compounds are quite differ-
ent in their effects from the other carbonates and bicarbonates men-
tioned. While the others are evacuant and promote secretions, the
calcium compounds constipate and decrease the secretions. Very
obstinate cases of chronic diarrhea have often been cured by a sojourn
at a spring rich in calcium bicarbonate. Uric acid gravel and ealculi
are disintegrated and eliminated by the free use of calcic carbonated
waters. ;

Ferrous and manganous bicarbonates.—Neither iron nor manganese
ever occur in mineral waters as the carbonate, but usually as the
bicarbonate. Both of these compounds have practically the same
effect. When taken internally, they are dissolved by the gastric juice
and taken into the blood. They increase the appetite and the number
of red blood corpuscles. It will thus be seen that such waters give
excellent results when used as a tonic or in cases of anemia. ‘Too
long continued use of waters rich in bicarbonate of iron or manganese
result in constipation and derangement of the digestion.

CHLORIDES.—Chlorine occurs in waters as chlorides, in combination,
most frequently, with sodium, potassium, or lithium, and sometimes
with calcium, magnesium, or iron. The chlorides form the basis of
that large group of mineral waters, the muriated salines.

Sodium chloride occurs in almost all mineral springs to some slight
extent, but in the muriated saline waters it occurs in large quantities
asa predominating constituent. Waters containing large quantities
of this substance are chiefly used in giving baths, which increase the
action of the skin, and by absorption through the pores serve as a
genuine tonic. ‘Taken internally the flow of the digestive fluids is pro-
moted and the appetite increased. Putrefactive changes in the intes-
tines are also prevented. In large doses sodium chloride increases the
flow of urine and the amount of urea present in the same.

Potassium chloride has very much the same effect on the human
system as does sodium chloride.

Lithium chloride has practically the same effect as lithium carbonate
and bicarbonate mentioned above.

Magnesium chloride is often used medicinally as a cathartic and to
increase the flow of bile.

_ Calcium chloride occurs in a number of muriated saline springs. It
is used in cases of general debility as a tonic. It increases the flow of

28 HOT SPRINGS, ARKANSAS.

urine and perspiration and waters containing it are used in the treat-
ment of scrofulous diseases and eczema.

Ferrous chloride.—The occurrence of this substance in mineral waters
is rather rare. When present, however, it acts as a tonic and in gen-
eral has the same properties as ferrous bicarbonate, already mentioned.

Ammonium chloride.—W hen used internally it has the stimulating
effect of ammonia. It is used in nervous cases as ovaralgia, se iatica,
and other neuralgic disorders. In congestion of the liver its use has .
been beneficial. Externally it is used as a wash for ulcers and sores.
It, however, seldom occurs in springs in quantities large enough to be
of any value.

SULPHATES are frequently found in mineral waters, and when present
in large quantities give rise to that large class, the sulphated salines.

Sodium and magnesium sulphates, or Glauber and Epsom salts
respectively, in small doses act as a laxative, in large doses as a
cathartic. They are both valuable in increasing the flow of the intes-
tinal fluids and in increasing the flow of urine, accompanied by an
increased elimination of urea. Waters containing these salts are of
great service in eliminating syphilitic, scrofulous, and malarial poisons
from the system, and in eliminating mercury and other metallic
poisons. Persons suffering from obesity, derangement of the liver,
and Bright’s disease are perhaps the most benefited by this class of
waters. It must be borne in mind that such waters should be used
with great care by the feeble and anaemic.

Potassium sulphate i s frequently present in mineral waters, but in
smaller quantities than the magnesium and sodium salts. Its action
is practically the same as that of the other two sulphates mentioned
above.

Calermm sulphate occurs in a great many mineral waters, and is the
component that gives to them the property of permanent hardness. — It
is not used medicinally.

Tron and aluminum sulphates are usually found associated with each
other in mineral waters. They are both powerful astringents. The
waters containing iron sulphate are also used as tonics, but this is not
nearly as good a form in which to give the iron as is the bicarbonate.
Because of their astringent action, waters containing these two sub-
stances have been used with success in treating locally inflamed parts
of the mucous membranes and ulcers cn the outside of the body.

Toprprs.—The iodides are usually reported in mineral waters as the
potassium. or sodium salt. They occur in nearly all cases only as traces,
yet their action is shown ina marked degree. They are alterative in
effect and are consequently used in the treatment of scrofula, rheuma-
tism, and syphilis. While drinking waters containing iodides the flow
of urine is very much increased and mercurial and other metallic pol-
sions are rapidly eliminated from the system.

BromrpEs act as alteratives in much the same way as iodides but to
not so marked an extent. They also act as sedatives.

PHOSPHATES in mineral waters are usually reported in one of three
forms, viz, sodium, iron, or calcium phosphate. The sodium phos-
phate acts as a mild laxative, the iron phosphate as a tonic, and the
caleium phosphate as a medicine in those conditions of the body where
lime salts are deficient, as rickets, etc.

BorareEs.—Borie acid is not a very common constituent of natural
waters, but is found as the sodium salt in springs of southern Cali-

fornia in large amounts. Borax has been used internally to dissolve

lithic acid gravel. It promotes the menstrual flow, so may be used in

catamenial irregularities. Applied as a douche in catarrhal conditions
of the uterus it is of value.

NrrratEs.—Any nitric acid that may appear in a water is usually
reported as sodium nitrate. This compound does not usually occur in
waters to a marked extent unless they are contaminated. W hen pres-
ent in large enough amounts it increases the flow of urine and acts as a
purg ative.

Sriica.—Silica appears in mineral waters both as free silica and as
silicates. The medicinal vaiue of silica has not been thoroughly inves-
tigated, although one or two investigations have been made which seem
to show that it is of value when taken for cancer, and that sugar and
albumin have disappeare 1 from the urine upon using it.

The gases that usually occur in water are nitrogen, oxygen, carbon
dioxide, and hydrogen sulphide.

NITROGEN AND OXYGEN are present in all waters that have come in
contact with the air. On account of the limited solubility of both they
can not occur in waters in very large quantities. Neither of them
when present in waters has any medicinal value.

SARBON DIOXIDE is present in all natural waters to some extent, but
in some springs the amount is very large, thus giving rise to that lar ve
class of carbonated waters of which the Saratoga springs furnish a
good example. Such waters are extremely palatable, and large quan-
tities can be drunk without the full feeling which so often follows
copious drinking of water.. In moderate quantities such waters increase
the flow of the saliva, promote digestion, and tend to increase the flow
of urine. Obstinate cases of nausea can be often relieved by the use
of small quantities of highly carbonated waters.

HYDROGEN SULPHIDE Is present in many natural waters, giving to
them the odor of decayed eggs, and forming that large class, the sul-
phuretted waters. When such waters are taken intern ally they act as
an alterative, and are consequently of value in the treatment of syphil-
itic diseases. They increase the activity of the intestines, kidneys, and
sweat glands, so are of use in the treatment of rheumatism and cout.
Excellent results have been obtained when these waters were used in
treating many skin diseases and malaria.

THE MEDICAL VALUE OF THERMAL WATERS.

The curative effects of thermal waters are undoubtedly due, to a
large extent, to their stimulating effects on the excretory organs of the ©
skin and the kidneys. To fully understand this we have only to
examine the routine through which a patient passes at these thermal
resorts. The pores are first thoroughly opened and sweating begun
by immersing the patient in hot water for from three to ten minutes.
The patient is then placed in the steaming room for about five minutes
and at the same time drinks copiously of hot water. ‘This treatment,
of course, produces a profuse perspiration. After this the patient is
wrapped i in blankets and passed on to a warm room for twenty to thirty
minutes, where the perspiration runs off in streams. After this the
patient is rubbed down and allowed to dress. A desire to urinate soon
comes. Thus we see that the system is thoroughly flooded with water
and washed out each day, and that tissue changes take place with won-

dertul rapidity. It is no wonder then that uric acid, sy phils poisons,
other materials of disease, and mercurial and other ‘metallic poisons
are soon eliminated from the system. With such effects as those men-
tioned above, hot baths then must be of value in the treatment of
rheumatism, gout, syphilis, neuralgia, ete.

SUMMARY OF THE RESULTS OF ANALYSIS.

On looking over the results of analysis of the various hot springs
it will be seen that the total mineral matter in solution is very nearly
the same in all except springs 12, 20, 27, and 43. Spring 12 is nearly
cold, and contains only 170.1 parts of mineral matter per million;
spring 20 contains _only 231 parts of mineral matter per million:
spring 27 only 258.7 parts of mineral matter per million, while spring
43 contains the relatively large amount of 310 parts of mineral matter
per million. The average amount in all the springs is between 275
and 280 parts per million; seldom falling below 270 parts per million
or going above 290 parts ‘per million.

As to the percentage composition of the mineral matter in each hot
spring the results are very much the same, except in springs 12, 27, 37,
41, and 43. Spring 12 has a higher percentage of silica and sulphuric
acid than the average, and a lower percentage of bicarbonic acid and
calcium; spring 27, a higher percentage of silica and a lower percent-
age of bicarbonic acid and calcium; springs 37 and 41, a higher per-
centage of sulphuric acid; and spring 43 a lower percentage of silica,
bicarbonic acid, and magnesium, and a much higher percentage of
sulphuric acid, potassium, and sodium. Although the springs men-
tioned above vary to some extent from the other springs in the amount
and composition of their mineral matter contained in solution, this
variation is not enough, in the author’s opinion, to make any differ-
ence in their medicinal value except in the cases of springs 12 and 43,
the first of which is markedly weaker in medicinal constituents than
the other springs, and the second of which has much more of those salts
present which have a laxative effect.

From what has already been said, combined with the analyses of
these waters, it will at once be seen why they have been used with such
excellent results in the treatment of rheumatism, gout, syphilis, ete.
We may sum up under four heads:

(1) The waters are hot, and consequently possess the medicinal value
of all thermal waters, i. e., when used as a bath, in the ordinary man-
ner followed in such cases, they stimulate the flow of sweat and urine,
and thus give the system a thorough washing out each day. In this
manner uric acid and syphilitic poisons are removed from the body.
Mercury and other metallic poisons are also removed, in consequence
of which much larger doses of mercury can be given to the patient
than would otherwise be possible.

(2) These waters contain iodides and bromides,* which, although
present only in traces, undoubtedly have a marked alterative effect on
the system, and form soluble compounds with the salts of mercury,
thus aiding in their elimination from the system.

(3) The presence of lithium in these waters, even though in traces,
very likely accounts, to some extent, for the removal of some of the
uric acid from the system, and the consequent improvement in the
condition of rheumatic and gouty persons.

(4) All of these springs contain quite large amounts of calcium and
magnesium bicarbonates. The calcium and magnesium salts of uric
acid are much more soluble than the uric acid itself. Taking these
two facts into consideration, it seems plausible to assume that a great —
deal of the curative effects of these waters is due to the formation of —
the more soluble compounds, calcium and magnesium urate, which can
more easily be eliminated from the system than the uric acid itself.

GEOLOGICAL SKETCH OF THE HOT SPRINGS
DISTRICT, ARKANSAS.

By WALTER HARVEY WEED,
Geologist, United States Geological Survey.

GEOGRAPHICAL LOCATION.

The Hot Springs of Arkansas are situated in the geographical center
of the State, 50 miles distant from Little Rock, and about 75 miles east
of the Indian Territory line. A city of about 60,000 inhabitants has
been built up about the Hot Springs and the place is a resort fora
large number of visitors from all parts of the Union. The locality is
accessible by two railway lines which connect with the Iron Mountain
Railway and the Choctaw route, running through cars from the large
cities of the country. The location is 600 feet above sea level and lies
at the easterly base of the mountain complex known as the ‘* Ouchita
Range,” the nearby peaks of which are oftentimes called the ‘* Ozark
Range,” although that name really applies to the mountains in the
northern part of Arkansas and the southern part of Missouri.

HISTORICAL NOTES.

The Arkansas Hot Springs have been known since the early settle-
ment of Louisiana. Although it is only a legend that they were vis-
ited by De Soto on his trip to the Mississippi, there is no doubt that
they were used by the Indians before the advent of Columbus, as abun-
dant evidence was found in early days that the Indians quarried the
dense rocks near the Hot Springs for arrowheads and spearheads and
utilized the spring waters for bathing.

In 1804 two members of the Lewis and Clarke exploring expedition
visited the place and found that white visitors had already used the
waters for bathing. In 1818 the lands on which the springs are located
were ceded to the General Government by the Quapaw Indians and
became afterwards a part of the Territory of Arkansas. The ground
about the springs was located by various claimants before the organi-
zation of the Territory of Arkansas, but by act of Congress the springs
and the ground about them were reserved in 1834 for the United
States Government, thus making the first national park reservation
of the country. Owing to the claims made by various parties toa
private ownership of the springs they remained in the possession of
such claimants until the United States Supreme Court decided in favor
of the Government in 1877.

80 HOT SPRINGS, ARKANSAS.

The act of Congress of March 3, 1877, provided for the appointmen ;
by the President of three commissioners, whose duties are defined by

said act as follows:

Sec. 3. That it shall be the duty of said commissioners, after examination of the

topography of the reservation, to lay out into convenient squares, blocks, lots,
avenues, streets, and alleys, the lines of which shall correspond with the existing
boundary lines of occupants of said reservation as near as may be consistent with the
interests of the United States, the following described lands, to wit: The south half
of section twenty-eight, the south half of section twenty-nine, all of sections thirty-
two and thirty-three, in township two south and range nineteen west; and the north
half of section four, the north half of section five, in township three south and range
nineteen west, situate in the county of Garland and State of Arkansas, and known
as the Hot Springs Reservation. ESOS:

Sec. 4. That before making any subdivision of said lands, as described in the
preceding section, it shall be the duty of said board of commissioners, under the
direction and subject to the approval of the Secretary of the Interior, to designate a
tract of land included in one boundary, sufficient in extent to include, and which
shall include, all the hot or warm springs situate on the lands aforesaid, to embrace,
as near as may be, what is known as Hot Springs Mountain, and the same is hereby
reserved from sale, and shall remain under the charge of a superintendent, to be
appointed by the Secretary of the Interior: Provided, however, That nothing in this
section shall prevent the Secretary of the Interior from fixing a special tax on water
taken from said springs, sufficient to pay for the protection and necessary improye-
ment of the same.

In the year mentioned a Commission was appointed and recommended
a permanent plan of improvement. Under that plan the land not
needed for permanent reservation was platted in streets and alleys,
and lots were assigned to various individuals. The original reserva-
tion consisted of 2,529 acres, of which 700 acres were awarded to indi-
viduals for business and residence purposes, 358 acres were used for
streets and alleys, and 570 acres were platted in town lots reserved for
future disposal.

In 1876 the town of Hot Springs was incorporated, and in 1881 the
General Government donated to the city the ground platted for streets
and alleys. The Congressional enactment of June 16, 1880, provided
as follows:

Sec. 3. That those divisions of the Hot Springs Reservation, known as the moun-
tainous districts, not divided by streets on the maps made by the commissioners, but
known and defined on the map and in the report of the commissioners as North
Mountain, West Mountain, and Sugar Loaf Mountain, be, and the same are hereby,
forever reserved from sale, and dedicated to public use as parks, to be known, with
Hot Springs Mountain, as the permanent reservation. :

Under these two acts the mountains adjacent to the springs are per-
manently reserved for parks, the hot waters are piped to various bath
houses, and the supply is under the control of a superintendent of the

Hot Springs Reservation, appointed by the Secretary of the Inte-—

rior. The regulations now prescribed by that Department provide
for a rental of land used by various individuals and for the payment
of $30 per year for each tub used by bathing establishments. The
income is used for the payment of administrative expenses, for the
maintenance of a free bath house, for the building of roads and path-
ways on the mountains back of the springs and the adjacent mountains,
and for gardening. The receipts amount to about $18,000 per year.
The superintendent is charged, under the supervision of the Secretary
of the Interior, with the care of the entire reservation as well as its pro-
tection and improvement. It is therefore policed and improved by the
Department. The results achieved by this wise system speak for them-

selves; beautiful driveways, picturesque walks, and fine flower beds add
their charm to the natural beauty of the place, and the present aspect
bears but a slight resemblance to the scene shown in the accompany-
ing illustration, Plate I, which represents the springs as they appeared
in 1836.

RELATION OF HOT SPRINGS DISTRICT TO REST OF THE STATE.

Central Arkansas consists of a low-lying, nearly level eastern por-
tion, and a western hilly or mountainous region. The first region
extends from the Mississippi River westward to Little Rock, Benton,
and Malvern. The hilly country of the Ouachita Mountain system
begins just west of the Iron Mountain Railroad, where it has a width
of 36 miles, and extends westward, gradually narrowing as it approaches
the Indian Territory. The eastern level country is part of the Tertiary
Mississippi Valley region. The western hilly country consists of a cen-
tral complex of hills, flanked by sharp spurs and ridges, which extend
outward into a much lower country of slight relief. This hilly coun-
try, is dignified by the name of the ‘‘Ouachita Mountain system,”
the ridges rising gradually in elevation westward. Near the Indian
Territory line the general level of the intermontane plain is 1,000
feet above tide and the crests of some of the ridges attain elevations
above 2,500 feet. Near Hot Springs the mountain area seldom attains
an elevation of more than 1,200 feet above the sea, or 600 feet above
the surrounding country, yet, when seen from the lower country about
it, the hills rise so abruptly that they appear to deserve their desig-
nation. The mountains near the Hot Springs are particularly im-
pressive, and the local summits have received special designations, as
*“*West Mountain,” ‘‘ Indian Mountain,” ete. These mountains have
been grouped together by some writers under the name of the ‘‘ Ozark
system,” but they have been more fittingly christened the ** Zigzag”
Range by Professor Branner, of the State geological survey. This
range has an extreme length of 25 miles and a width of 6 to 8 miles.
The general trend of the ridges is almost at right angles to the system.
These ridges are narrow and sharp, with a height of 500 to 600 feet,
and they are particularly numerous in the vicinity of the Hot Springs.

TOPOGRAPHY.

The Hot Springs are situated in a valley between two wooded,
rocky ridges known as ‘*‘ West Mountain” and ‘‘ Hot Springs Moun-
tain.” The water issues from vents in theeold and gray hot-spring
deposit, or tufa, that covers the basal slopes of Hot Springs Moun-
tain east of Hot Springs Creek. This location is on the outer
border of the mountain system. To the east the country falls away
gently to the Ouachita River, and the city of Hot Springs has been built
partly in the ravine and the intermontane basin to the north and
partly in the eroded plateau lying south of the springs and outside of
the mountain area. The mountain slopes are rocky, and are often
ribbed with abrupt cliffs and rugged ledges with extensive slopes of
talus. They are generally thickly mantled with a heavy forest growth
of oak, pine, chestnut, and other common forest trees, and they support
a more or less abundant undergrowth. The ravines are generally

narrow and the streams swift running, but good exposures of the
underlying rocks are seldom seen, owing to the thick forest that
covers the slopes. There is an evident relation between the hard rocks
and the hills and between the softer rocks and the valleys, although
the streams do not accord with any definite geological structure, but
flow in synclines, in eroded anticlines, and across the strike of the beds
as well. Several gaps indicate old and now abandoned stream courses
and show a prolonged period of adjustment, in which the streams shifted
several times before reaching their present position. Although the
springs are on the borders of these mountains this location is not
wholly outside of the mountain area, since the Trapp Mountain Range
lies south of the Ouachita River, so that the springs are on the north
side of a synclinal basin that forms an embayment between the main
Ouachita system and a small east-and-west spur on the south. The
region is well watered and well drained. Ir ‘he immediate vicinity of
Hot Springs the Hot Springs Creek and Gulpha Creek, both of which
flow into the Ouachita River, drain the entire region, the former stream
flowing due south and reaching the river 4 miles below the city.

The lower country near the springs, upon which a considerable part
of the city is built, is a dissected plain in which broad plateau levels
alternate with shallow drainage courses tbat are tributary to Hot
Springs Creek.

The climate of the region is a miid one, lacking both the extreme
heat of summer and the cold of winter. In the summer months the
air is tempered by the breezes from the mountains, «nd in winter the
average temperature is very slightly below that which prevails at New
Orleans and other Southern cities. Flowers and shrubs of semitropical
character grow in the open air, but the occasional frosts of winter are
so sharp that a strictly semitropical vegetation will] not exist.

ROCKS OF THE DISTRICT.

The rocks seen about the Hot Springs are chiefly of sedimentary
origin and were formed beneath the waters of a Paleozoic sea. They
occur in well-defined formations, which were folded when the moun-
tains of the region were formed by the compressive stresses of earth
movements, and these folds have subsequently been eroded by ordinary
atmospheric agencies. These rocks are cut by a few narrow, insig-
nificant dikes of igneous rock, which are supposedly connected with
the large masses of granite and other igneous rocks now seen at
Magnet Cove and Potash Sulphur Springs. In addition to the rocks
mentioned there is a considerable area of dark-gray and porous tra-
vertine, or calcareous tufa, formed by the Hot Springs.

The sedimentary rocks seen in the vicinity of the Hot Springs con-
sist of shales, sandstones, a few beds of impure limestone, and the
rock called novaculite. This last-named rock, of which the well-known
Arkansas whetstones are made, is the most conspicuous and important
rockin the locality. It is the typical rock of central Arkansas, and,
though found over a large area, the material pure enough to be used
for whetstones is confined to the vicinity of the Hot Springs. It is
this rock that has, by reason of its hardness and its resistance to erosion,
made the mountains about the springs, and it forms the cliffs and
prominent ledges seen in the district. The bedded rocks form a series

The rock structure.—Near the Hot Springs these rocks have been
compressed into great folds which now form the mountains, and this
compression is so great that the folds have becn pushed over, or over-
turned, and in the gorge of Hot Springs Creek the section now exposed
shows the younger beds resting beneath the older ones. In addition
to this there has been some faulting in Indian Mountain, by which
an overthrust has pushed up the older beds over younger ones. For
this reason the section, as given above, is not always easily made out,
but it can be seen in the slopes of West Mountain, although, as will be
noted there, the younger beds lie below the older and the rocks have
a dip of from 25° to 70°. The Carboniferous shales, which are the
youngest rocks of the district, are well exposed on Malvern avenue
near the Park Hotel, where the olive-colored, sandy shales have been
found to contain plant stems and fragments of fern fronds. The shales
are rarely indurated enough to form slates, though a few quarries have
been opened in them and slate of a poor quality extracted. Where
the shales are slightly altered they are sometimes valuable for brick
and terra-cotta burning, though most of the clay used for that purpose
is derived from the disintegrated material washed into the creek
bottoms.

The sandstones are of variable texture andcomposition. The coarser-
grained rocks are nearly pure quartzose sand, but the intermediate
beds are quite clayey. The chief sandstone horizon seen at the springs
is the one lying just above the novaculites, and this rock is the one
which is so prominent on Hot Springs Mountain and West Mountain.

The novaculites are the most interesting rocks of the region. They
consi:t of nearly pure silica, containing less than one-half of 1 per
cent of other material. The rock is very dense, homogeneous, of a
cream or white color, and fine grained, resembling in appearance the
finest Carrara marble. These rocks are used for whetstones, the finer-
grained form being called Arkansas stone and the coarser-grained rock
the Ouachita stone. This material has a marked conchoidal fracture

and resembles chert in its general appearance, although, as will be
shown later, this appearance is purely a superficial one and the mate-
rial differs markedly from chert in its origin and composition.
Although brittle and lacking the toughness of chert, it was exten-
sively used by the Indians, who quarried it by building fires upon the
outcrops until the stones were heated and then quenching the fire with
water, thus chilling the rock and causing it to split and spall into frag-
ments which were easily removed. In this condition it was readily
chipped by the use of round stone hammers, great quantities of which
have been found by the early settlers and which the writer has seen at
some of the more remote quarries. The rock is finely jointed, and in
quarry faces this jointing is more conspicuous than the bedding planes.
These phenomena may be well observed in almost any of the excava-
tions seen along the main street above the Government reservation.
The finer-grained material seldom forms good outcrops, because of this
jointing and also because the rock contains a small amount of water,
which, when frozen during the frosts of winter, shatters the stone and
covers the outcrop with fine débris. This débris is extensively used
as a road material, and wherever applied forms a most excellent
surface.

The novaculite formation is from 500 to 600 feet in thickness, which
includes some flinty shales, some soft shales, and some sandstones. The
novaculites proper are prominent members of this formation and occur
in beds a few inches to 12.0r 15 feet thick. When these beds are less
than 4 inches thick the rocks lose the novaculite character, and are
more like flinty shales. When examined under the microscope the
rock is found to present a very uniform appearance, and to consist
of extremely minute interlocking grains of cryptocrystalline silica.
Chemical tests show that this silica is quartz and not amorphous silica.
Thin sections also disclose the presence of numerous cavities in the rock
quarried for whetstones. These cavities have been found to present a
rhomboidal outline, and they correspond in form and position to included
patches of calcite found in the same rock where the bed passes heneath
the creek levels. It has been assumed that these cavities are formed
by the dissolution and removal of the calcite, and as the material from
beneath the water level is of slight value as a whetstone, it has been
reasoned that the abrasive qualities of the Arkansas stone are due to
the presence of these calcite cavities. The origin of the rock has been
the subject of considerable speculation from the earliest times to the
present. It has been commonly asserted that it is a very fine-grained
sandstone, which has been indurated and altered by hot-spring action.
This explanation is not adequate, however, since the same beds are
exposed on the flanks of the Ouachita Mountain system for a total
length of several hundred miles. Moreover, the character of the grains
does not permit of the assumption that they were originally rounded
and that the spaces between have been filled by secondary deposition
of silica, as is commonly the case with many quartzites. The writer’s
belief is that the evidence supports the opinion that the rocks were
formed as a chemical precipitate in the deep seas of a Silurian ocean,
and that comparatively little alteration beyond induration has taken
place. Such a theory seems to accord very well with the chemical and
physical nature of the rock and with the facts now known in regard to
the origin of some of the early geological sediments.

HOT SPRINGS, ARKANSAS. 85

IGNEOUS ROCKS.

Besides the sedimentary rocks just noted there are four narrow dikes
of igneous rock about one-half mile south of the mountain borders and
near the city limits. These rocks are dark-colored mica traps, a form
of rock called ‘‘ ouchatite.” They are chiefly interesting because they
show that there was some deep-seated body of molten material from
which the dike fissures were supplied. Small dikes are found north -
of the city, east of the city, and in considerable abundance about Pot-
ash Sulphur Springs and at Magnet Cove. These dikes have a gener-
ally ESE.-WNW. direction, showing that the fissures are parallel
to the mountain sides. They are from 1 to 4 feet wide and are gener-
ally much altered, so that the outcrop is inconspicuous, or is covered
by vegetation, and when the rock is broken black mica in small flakes
is the only mineral seen.

FOSSILS.

The age of the sedimentary rocks is determined by the fossil remains
found in them. The black shales which underlie the novaculites
contain remains of a curious hydrozoa. These fossil remains are known
as graptolites, and the forms identified at the Hot Springs belong to the
upper part of the Lower Silurian age (Trenton and Utica). New
types of these fossils peculiar to the Hot Springs are illustrated in
the Noyaculite report issued by the Arkansas geological survey.
Besides these curious forms, a few shell remains (brachiopods and
lamellibranchs), corals, and worm trails have been found. The grap-
tolites occur on the north side of the hill on a small stream drainage
on the west side of the continuation of Park avenue. They are also
seen in a very black shale forming the bluff on the west side of Park
avenue above the Hotel Hay and below the Barnes House. Similar
fossils also occur on Whitington avenue, one-fourth of a mile above
the head of Central avenue, at a point where the creek crosses the
street.

Plant remains of Lower Carboniferous age have been found in the
shales exposed in the excavation for a cellar on the western side of
Malvern avenue, 100 feet north of the Park Hotel. The shales are
varicolored, brown, red, gray, and black, but the fossils occur in the
olive-colored, sandy shales. Similar fossils were also found in Ouach-
ita avenue at the Hot Springs.

OCCURRENCE OF THE HOT SPRINGS.

The hot waters issue from the base and lower portion of the slopes
east of the valley. This area is a narrow strip, a few hundred feet
wide, and a quarter of amile long. In its general aspect this area is dis-
tinguished from the rest of the mountain by its patches of barren gray
tufa, the old hot-spring deposit, and the absence of forest growth. From
the descriptions given by earlier writers, it is evident that this difference
in appearance and vegetation was formerly very marked. To-day the
springs are all covered, and mostly concealed beneath turf and shrub-
bery. The old tufa deposit is in large part covered by soil and plants.
The creek is arched over and sidewalks and roadways are built on it.
The space between creek and hillside is covered by the bathing establish-
ments, which, in many instances, are built directly over large springs.

86 HOT SPRINGS, ARKANSAS.

The landscape gardener has modified the old slopes, filled up the gullies,
and built roads and footpaths, until the hot-spring area is a beautiful
park and a fitting setting for the springs.

The great contrast between the present appearance of this area and
that of a half century ago is shown by a comparison of the sketch made
by Prof. David D. Owen, State geologist, in 1859, which is reproduced
in Plate I, and the present aspect, shown in Plate II and the frontispiece.

The diagram accompanying this report, Plate [X, shows the location
of the hot springs with reference to the buildings on the reservation.
The numbers on this map correspond to those given in the table of analy-
ses. Professor Owen’s sketch map is also reproduced for comparison.

The topography of the district is shown in Plate X, which is part
of a general sheet prepared by the United States Geological Survey.
This shows that the springs occur at the southwest end or ‘‘ nose” of
Hot Springs Mountain. There is nothing unusual or remarkable in
this topographic position, for it accords with that of many other springs
of the region—as, for example, Bonanza Springs and Big Chalybeate of
the plate.

It is difficult for the average visitor of to-day to form an idea of the
natural appearance of the springs. The larger springs formerly issued
abruptly from the tufa slopes and did not possess the bowls and basins
seen at the Mammoth Hot Springs of the Yellowstone. An artificial
cutting made into the mound of the Cave spring (Plate V) shows a sec-
tion of the hot-spring deposit, and if the door be opened the waters will
be seen flowing into the basin cut to collect them, and depositing creamy
alabaster-like tufa, and the brilliant emerald-green tufa, whose color is
due to the growth of hot-water alge. Many of the smaller springs
are mere oozes, with no well-defined channel. A considerable number
of these are gathered into one reservoir at the base of the tufa bluff
between the Arlington Hotel and the Superior Bath House. Another
spring is seen near the Hale Bath House, where it issues from a cavity
in the tufa and flows into the basin seen in Plate VI. There is a con-
stant flow from the tufa wali back of this masonry pate forming
the dripping spring, where thousands of visitors daily drink hot water
direct from the rock. At this place also the green algous growth may
be seen. Owing to artificial protection given the springs, but few
notes could be taken of their present appearance, and these are recorded
in the following table: (*)

88 HOT SPRINGS, ARKANSAS.

HOT SPRING TUFA DEPOSIT.

As already noted, the hot-spring area is characterized by a deposit
of calcareous tufa, or travertine, formed by the hot waters, and cover-
ing not only a large part of the mountain slope about the existing hot
springs, but also extending westward to the Happy Hollow ravine and
occurring far above any existing springs in the slope above the band
stand (Plate III). Tufa deposits are common about both hot and cold
water springs whose waters carry carbonate of lime insolution. This
material is precipitated when the carbon dioxide of the waters escapes
upon exposure of the water to the atmosphere. At the Arkansas Hot
Springs a very small amount of carbonate of lime is held in the waters,
yet it is sufficient to coat the hot-water pipes and to fill wooden troughs
used to conduct the waters. In the Cave spring and at the Dripping
spring (Plate VI) the tufa may be seen now forming. It is therefore
not certain that the waters which formed the great tufa deposits o£ the
place were any richer in lime carbonates than those of to-day. This
tufa is seen in its natural state at many places about the springs, but is
particularly well seen at the Cave spring back of the Arlington Hotel.
It is of a gray color and porous texture on the surface, but when quar-
ried is pure white, compact, and crystalline. The steps shown in Plate
VII are cut in it and the porous texture is seen in the fragments on
edge alongside.

This tufa consists almost wholly of carbonate of lime, carrying very
small and varying amounts of manganese (oxide) and iron oxide. The
manganese is frequently prominent as a black powder, or occurs in
blackish layers through the rock. The analysis made for Owen in 1859
of the material deposited in the pipe accords so exactly with that of the
deposit now forming that it is reproduced.

In the Cave spring the freshly deposited tufa is tinted orange by the
alow that live in hot water, and green by the species that flourish at
slightly lower temperatures. These colors are purely vegetable and
disappear if the deposit be heated.

This tufa deposit covers an area of approximately 20 acres, and varies
from a few inches to 6 or 8 feet in thickness. Its occurrence shows
that some of the springs formerly flowed to the west, and that the
waters covered a larger area than at present.

The broad area covered by the tufa does not mean that the hot
waters covered this entire area at any one time, for the algous growth
described as filling the hot-water streams causes a filling up of the
channel and a diversion of the water to a different place. In two
instances the waters built up mounds about the springs. The most
noticeable of these is that of the Cave spring, which has been artifici-

“HA SLV1d

HOT SPRINGS, ARKANSAS. 89

ally breached in the development of a larger water supply from the
spring. (Plate V.) Above the music pavilion another area of tufa
indicates the former presence of springs at a level higher than any
now existing.

The thickness of the tufa deposit is likely to be overestimated, as it
covers steep slopes and even cliff faces.

The earliest description of the place tells of its forming overhanging
masses alongside the creek, whose flood waters swept away its sup-
port. The natural exposures of conglomerate and sandstone outcrop-
ping near the pavilion show that the tufa is there underlain by hard
rock. Farther west, however, the tufa overlies soft, shaly rocks,
which haye been digested by the hot waters and vapors for so long a
time that the material is as soft as ashes, and in the development of
new water supplies near Spring No. 1 a pipe was driven 38 feet down
into this material. Immediately beneath the tufa there is a breccia of
novaculite sandstone or shale fragments cemented by iron oxide, man-
ganese oxide, and carbonate of lime. This is seen under the tufa at
the Cave spring and at the Dripping spring. It merely represents
the old hillside débris cemented by the hot-water deposit and material
‘deposited later beneath the tufa mantle.

The owners of the Hale bath house have cut a short tunnel into the
tufa hack of their establishment, and the natural heat of the ground is
used for a vapor bath. There is no doubt that the ground back of
Bath House Row is permeated by a network of fissures and is heated
by hot-water vapors.

Vegetation of tufa area.—TVhe tufa area is described by all earlier
writers as being distinguished from the adjacent slope by its peculiar
vegetation. In the improvement of the reservation this distinction
has been largely obliterated, as flowers and shrubs have been freely
planted. The tufa cliffs and rougher exposures show, however, the
limestone-loving ferns Cheilanthes alabamensis Kunze and Adiantum
capillus-veneris L., which occur nowhere else in this region. Owen
mentions these ferns especially, besides numerous peculiar mosses and
aloze, and the stonecrop, sage, lobelia, and senna as characteristic of
the tufa area.

GEOLOGICAL RELATIONS OF THE HOT SPRINGS.

In the geological sketch already given the rocks from which the hot
waters issue are described as sandstones and shales of Lower Silurian
age, occurring in sharply compressed folds. ‘The hot waters issue from
the sandstones seen well exposed back of the superintendent’s office
and near the music pavilion, and from the overlying shales in the area
west of the pavilion. These rocks form part of a steeply dipping anti-
cline plunging beneath the surface toward the southwest. It may be
compared to the partly buried prow of an upturned boat. The rocks
arch around the mountain slopes, the different beds being revealed very
niuch as the scales of an onion bulb are exposed when it is partly cut
into. While the rocks are flexed into this great curve, the great and
thick beds of hard sandstone and conglomerate were cracked while
being flexed, and little slips and breaks occur. The smaller cracks
form a network of fractures, which in some places are seen to be filled
with white quartz. The map shows the principal springs to be arranged
along a line running about NNE., or parallel to the axis of the fold

90 HOT SPRINGS, ARKANSAS.

forming Hot Springs Mountain. This line is believed to be a fissure
corresponding to a fracture of the northwest fold, a fault fissure.
Springs are common along such fractures in the novaculite region of
Arkansas, and there is no reason to believe there is anything unusual
in this one. The source of heat is discussed elsewhere.

THE HOT SPRING WATERS.

The Hot Springs yield waters of remarkable purity. This, in fact, is
the reason ascribed by some physicians for the efficacy of the water
as a remedialagent. The very complete analyses given in this report
show a very small amountof mineral matter. The purity of the natu-
ral waters of the region is well known. The water of the Happy Hol-
low spring has less mineral matter than any other of the waters known,
except that of the Poland spring, of Maine. ‘These waters rise through
siliceous rocks, and the fact that the hot waters contain so little mineral
matter, particularly silica, is evidence of their meteoric origin, and
accords with the nature of the gases given off by the springs.

A direct comparison of the analyses with those made in earlier years
is not possible, since the analyses are given in parts per million, while
those of the State geological survey are in grains per gallon. I have
recalculated the analyses of the larger springs, however, and find the
analyses nearly identical, showing conclusively that the nature of the
waters is not changing with time.

The accompanying table gives a recapitulation of the analyses made
by Mr. J. K. Haywood, of the Bureau of Chemistry, Department of
Agriculture.

92 HOT SPRINGS, ARKANSAS.

Gases.—The gases given off by the hot waters were carefully col- —
lected and analyzed. The results show that they consist of carbon
dioxide, oxygen, and nitrogen. The ratio of oxygen and nitrogen
corresponds very closely to that of atmospheric air, and, taking into
account the relative absorption of the two gases by water, there can be
no doubt that the oxygen and nitrogen given off by the water come
from absorbed air.

Source of water.—F rom what has already been said in discussing the
geological and topographical relations of the springs, and from the
composition of the water and of the gases, there seems no doubt that
the hot springs correspond closely to the ordinary springs of the
mountain region save in the very important element of heat. As will
be shown later, it is believed that the waters of a very large but
entirely normal spring, or springs, have been heated by vapors rising
through fissures penetrating its unknown depths.

Source of mineral contents.—The mineral matter of the waters has
come from the rocks traversed by the waters. Recollecting the solvent
power of hot water, it is rather remarkable that the waters are so pure.
The underlying rocks are Silurian sediments resting on an unknown
complex, but the Silurian rocks alone are competent to supply all the
mineral matter of the waters.

ARE THE HOT SPRINGS DYING?

The question whether the hot springs are changing in character
and will eventually either cease flowing or become cold springs
is of both popular and scientific interest. The evidence seems to
show that there is a very small decrease in temperature since they
were first examined, now nearly a century ago. The temperature
recorded by Dunbar and Hunter in 1804 for the larger spring was 150°
F., and another had a temperature of 154°. In 1859 the springs were
carefully examined by David Dale Owen, State geologist, whose map
of temperatures and elevations is reproduced in Plate VIII herewith.
A more accurate map was published by William Glasgow, jr., in 1860
from careful instrumental surveys, together with records of temper-
ature and outflow.

Since then many changes have been made about the springs, all of
which have been dug out and inclosed in masonry arches, with the
consolidation of two or more springs into one in some instances, the
development of new outflows by digging wells or sinking pipes, and
the drying up of adjacent natural outflows. For these reasons all the
springs now existing can not be positively identified with those shown
on the earlier maps, but a majority of them are so correlated without
doubt. ‘

Temperatures.—The comparison of the old records mentioned with
those recently made shows that the highest temperature known to-day
is 147° F., as against 154° in 1804, and 150° by Glasgow and 148° by
Owen in 1860. Ina number of springs there is a decline of 2° since
the latter date. Sucha slight difference might, however, be due to
differences in the manner or place of taking the temperatures, or the
instruments used in the earlier years may not have been accurate. Itis
noteworthy that Owen’s highest temperature, taken in 1859 with a
standardized thermometer, was 148°, and that recorded now is 147°.
In other words, the temperature is decreasing so slowly that the change

is almost imperceptible in half a century. In one instance, that of
the Alum spring, there is a very marked decrease in temperature,
and as this is the only spring on the west side of the creek, there is
no doubt of its identity. In 1804 this had a temperature of 132°.
In 1859 its temperature was 133°, according to Owen, and to-day it is
but 114.8°. :

Amount of outflow.—The comparison of outflow is more difficult.
According to Dunbar and Hunter the largest spring had an outflow of
11 quarts in eleven seconds in 1804, corresponding to 22,100 gallons
per day, and the four largest springs had an outflow of 165 gallons per
minute, or 237,600 gallons per day. Dr. Owen gives no measurements,
but Glasgow gives the discharge of each spring—a total of 317 gallons
per minute, or 450,480 gallons per day, as compared with 850,000 gal-
lons per day at the present time. As the writer has shown elsewhere,
the spring water is of meteoric origin, like most spring water, and prob-
ably varies somewhat from year to year, corresponding to variation in
annual rainfall at some previous year, so that no definite comparison
can be made with the early records, except to state that the volume of
water discharged is very much greater. Supposing a practically con-
stant amount of heat applied, this of itself would mean a slightly low-
ered temperature. In this connection attention should be called to the
well put down by Major Torney, U. 8. Army, in the Army and Navy
Hospital, which is capable of yielding the amazing amount of 350,000
gallons per day without affecting but one very small spring (No. 40
of the list).

From a consideration of all these facts it is concluded that the springs
are losing their heat so slowly that the loss is almost inappreciable.

Amount of mineral matter carried in solution by the waters.—No
essential difference in the composition of the waters can be detected
by a comparison of the analyses made for Owen or Larkin (1859) or
for Dr. Branner, of the State geological survey, in 1889, with the elab-
orate and careful analyses made by the National Government. The
waters are remarkable more for their purity than for their mineral
contents. The material in solution consists mainly of bicarbonate of
lime, which is so easily precipitated by the loss of carbonic acid gas
that a deposit forms in pipes, and rather rapidly where the spring
waters drip, as in the walls about the bowl of the Cave spring. The
total mineral matter for all the springs amounts to 1,367 pounds a
day, equivalent to 249.5 tons a year. This amount of material carried
by the hot water from the earth’s interior to the surface must leave a
very considerable cavity in the course of time.

SOURCE OF HEAT.

While there have been many theories advanced to account for the
source of the hot waters, the only hypothesis that stands the test of
scientific inquiry is the one which ascribes the heat of the waters to
still hot but concealed bodies of igneous rock. It seems scarcely nec-
essary to call attention to the absurdity of the idea that either slaking
lime in the depths of the earth or chemical reaction of the waters with
the atmosphere could be the cause of the heat. That the waters come
from a depth sufficient for their heating by the normal increment of
earth heat (1° for every 50 feet) seems unreasonable, since it would
necessitate a depth of nearly 5,000 feet to give the waters their pres-
ent temperature, even assuming that they were not cooled in their course

upward. The composition of the gases given off by the waters shows
that they contain atmospheric air as well as carbon dioxide. That the
heat of the waters is due to the heat developed by the folding of the
rocks, which is the theory given to account for the heat at the Virginia
Hot Springs, is not probable, for the folding at Hot Springs is not
more intense than elsewhere in the mountain regions of Arkansas, and
no evidence of hot spring action has been found at any other locali-
ties except where igneous rocks are present.

It is believed that the heat comes from a great body of still heated
igneous rocks intruded in the earth’s crust by volcanic agencies and
underlying a large part of central Arkansas. The existence of such a
mass is shown by the great bodies of granite seen at Potash Sulphur
Springs and Magnet Cove, where the rocks have been exposed by the
wearing down of the overlying sediments, though the igneous rocks
seen were of course long since cooled. At Magnet Cove, moreover,
there are tufa deposits which show the former occurrence of hot
springs.

OTE hypothesis is strengthened by the occurrence of intrusive dikes
at various localities about the springs, and their trend and occurrence
indicate that the molten material which filled the fissures did not come
from the bodies of rock now exposed at Potash Suiphur Springs or at
Magnet Cove, but had some deep-seated source, whose location is indi-
cated by the dikes as being approximately under the hotsprings. Deep-
seated waters converted into vapors by contact with this ‘*‘ batholith”
of hot rock probably ascend through fissures toward the surface, where
they probably meet cold spring waters which are heated by the vapors.
As the igneous dikes near by are fissures reaching down to this great
mass of igneous magma which have been filled by it to form dikes, it is

not unreasonable to suppose that fissures extend down to the now solid -

but still hot igneous mass.
