some time ago we sent sample Of
lola marble to classmate "a ours,
! Erasmus Haworth, who Is now Profess
sor of Chemistry. Mineralogy and Geo
logy in Penn College at OskaIoosa,
Iowa., and asked him to submit IL
to n close analysis and send Us
his opinion of it. Prof. Hawortb has
made speciality of Geology fora num-
Der of years, is a graduate of John
Hopkins University from which he
has the degree of Phi. D., is the author
of two works on Geology which have
attracted wide attention from scien-
fists, Is attached to the Z. 8. Geolog-
ical Survey at Washington, and is
recognized as an authority in his
special work. We therefore attach
the highest significance to hi. optimism.
knowing it to be both honest and in
formed, and we consider it, as given IN
the following letter, the very best our
marble has yetreceived. Prof.Haworth
says:
Editor Register:
L have made q careful microscopic
examination of the specimen of marble
which You sent me with the following
results. In order to do this, I broke
three fragments from different places
of the specimen so that they fairly

throughout. No signs of rottenness or
decay could be found.
Second. There seems to be n total

ing and cause the rock to erunble.
Different compounds of iron, such as
the sulphide or carbonate Of iron, IL
present, would easily change on ex-
pOsure to the atmosphere, and hereby
destroy the value of the rock. But no
traces of either of these could be found.
Third. The value of such a rock as
this depends largely on the degree to
which capitalization has developed
within it. y most careful microscopic
examination shows that no less than
nine-tenths of the rock IL composed Of
crystals, and consequently 1t il adapt
ed for use the same a. other marble.
Very respectfully,
ERASMUS HAwORTH.
In addition to the above official re-
port of his analysis, Prof. Haworth
enclOses more informal personal note
regarding the stone, from which We
quote the following:
The question of the real value of the
rock depends almost wholly on the ex-
tent to which 1t il crystalized. The
rock has evidently been formed tho
same as any other limestone and sub
sequently has been subjected to eer-
tain processes which have developed .
crystalline structure throughout 1t to
a very great extent.
Genuine marble Is wholly crystlline
the same as granite, but of course the
crystals have different chemical
composition from those i'm granite. A
microscopic examination il the only
way / know II to determine to what
extent this rock is crystalized. was
very much surprised to find that fully
nine tenths of the mass of the rock II
crystalline. 1t is easy to see with the
uDassisted eye that portions Of IL are,
ed that those portions which do not
look to be, in reality are almost entire
ly composed of minute crystals.
1t thus appears that another point
of great Importance in determining
the value of our marble has been set-
tied, and that as favorably as could be
desired. The beautiful color of the
stone shows for itself. Our marble
workers have shown that it is suscep-
tible to high polish. The highest
authority i'm America has established
its chemical identity with other well
known and popular marbles. And
now a microscopical analysis shows
it to be almost wholly crystalline, en-
tirely sound, and absolutely free from
Impurities that might render it sus-
ceptible to decay by the action of the
weather. Is any further proof needed
of the value and utility Of lola marble:
