CENTENNIAL EXHIBITION.
csu,,uucd from seeona Pase.

Itser kind. lie was with the German forces during
.ba siege of Paris. His detachment was
yvitbin range of Fort st. Valerie, but
had not yet been observed by It's gum
nem. The first shell from the fort came
rnexpectedly; was aimed with precision, and ex-
ooded an instant before it fell 1t was as II
rSoIe hardware shop had suddenly dropped on us
from the skyP 1t may be Judged that these
enormous guns of Krupp are meant for outdoor
or since it is specified in respect to the largest
be its carriage is intended for earth parapets OF 62s
ct high: but as the whole machine-gn
carriage and side-weighs over 100000 pounds
neh use seems scarcely practicable. The second IN
sz Of the guns Of Krupps exhibit called the long
o,n - IL weighs "a, 200 pounds. has a calibeI Of
ahont a inches, and total length Of II feet. Its
charge of powder and its projectes are each about
20 per cent of those of the greater gun. bnF the
initial velocity of the prOiectiles differs very ttle
There are Ave other guns IN Rrupps exnDls an
tbe seven are made out of cTueible cast steel Be-
s;dos the guns there is good show Of ores aud
steel products the latter including locomotive
,voools and tires and two large shafts but tho mill
tarv feature of this exhibit is the most pronounced
and in it there are lifesiSe figures OF horses carry
inc their loads for field service, and thoroughly sug-
ceytiye Of the business Of war.
The more peaceable exhibits of iron from Germany
srenear Krupp's guns, and OveIshadowed by them
There is a column of spiegeleisen from Cologne-a
sonare pyramid about nine feet to the side at the
base and 80 feet high. The spegel iron in the col
lectiyo exhibit near the pyramid is also noteworthy
and the specimens of spathc iron ore and of the kid
ney ores are very fine From the annexed territory
Of Lorraine and especially from Saarbruclen, where
one of the first battles Of the late war was
fought, there is good display OF iron
snd ores; from Lnxelnburg there are great
f.af aud
feet long; a casting from Upper Slesa weighs $3.50
pounds is about "a feet long and broad. In short,
the display of iron and its ores from Germany
though not arranged with good taste us the Swell
ish exhibit, is fully its equal in abundance of the
metal There some specimens of kidney iron ore
in the German exhibit which vertable euriosites;
semi-crystaline forms looking like bundles of rods,
or taking shapes like tho miniature columns of
basalt in toy models of tho Giants Causoway.
Belgium displays her iron aud steel in the main
building Perhaps the specimens were collected
hastily; they are not remarkable either for size or
excellence. There is varied show of girders, chan
mel bars rolled beams, spices, bolts, and railway
supplies. The SOciet6 Anoryme de la Providence
takes pains to let Americans know the price at
which it's IRON products can be laid down here. The
circumstance is Of interest this is the concern
which recently ss "the Providence Iron Works" as
don and taking largc orders in that market.
France is unfortunate in having her iron and steel
exhibit scattered in different buildings. ID corner
of Machinery Hall the specimens Of work from the
Rive de Gier district ara collected, including wheels
made by drop forging There is considerable ex-
bht of French iron and steel in Agricultural Hall
why there do not know-of which great pipes and
lalnp-posts form part. The Marseilles Gas Company
sends quantity of spiegeleseu.
Spain makes unique exhibit Of swords and other
arms forged in the national armory. In Russas de-
partment in Machinery Hail. Prince Demidotf makes
a very imposing display of heavy ronwork-rails,
chains, cables, sections of eannon-besides fine
collection of ores. Near this are smaller but meri-
tori0us exhibits by his fellow-countryTneD. There
is less napproprateness in pnttng the steel scythes
Of Hungary in Agricultural Hall than in SOME pre-
yously mentioned instances of scatteration but few
visitors would think of going there to find those
implements.
The show of iron STEEL and orc from onr own
country is enormous but unequal, tie States not
being adequately represented in sill instances. Let
us begin with New-York, rs that should interest
TRIBUNE readers most. This letter would become
mere directory of if it gave notice of all the
exhibits of other States but in the of Newlork
there are so few that it is quite practicable The
Albany Iron and Steel Company has a star-shaped
display, and from Moriah, Essex County, there is
show Of magnetic iron ore In the Govern
ment Building. Burden of Troy has horse
shoeing machine, and an exhibit in the Agricultural
Building. There are ChaInplain ores from Port
Henry in the Main Building-a very good display.
Tie Albany and Rensselaer, Steel Company have
sent their Bessemer steel The Rodgers Iron Com
pany of Ausable Forks show the virtues of Adj
rondsck metal The Chrome Steel Company Of
Brooklyn has good display. The Union Iron Com
pany Of Buffalo has three separate exhibits in the
Main Building 90 different specimens of beams,
channel bars, and the like; alongside the Main
Building half a dozen specimens of beams and of
bars Of angle iron one 15-nch beam being So feet,
and one 9-ineh beam so feet in length. The bars
weigh about half ton, the beams mostly over ton
each; all rolled at single heat. In the gallery
at the west end Of the Main Bui'1ng this concern
exhibits automatic blast furnace register for re-
cording the pressure of the blast. Beside these
things tho company has sent specimens of ores from
three of the Lake Superior mines and from mines in
st. Lawrence and Essex Counties, New-YoFk
Pennsylvania's display Of iron is simply immense.
The ores are well shown in the Mineral Annex, the
geologic survey of the State under the excellent
perintendenee of Prof J. P. Lesley having provided
abundant material. For the maps, models. and min
erals exhibited the State is indebted to the efforts of
John B. Pierce philosophical citizen. He is Soc
Istary Of the Geological Commission of the state,
bnt the Office is not salaried one. Coal and iron
are mingled all through the mineral exhibits
of Pennsylvania. 1t Is however generally
conceded that the best Of iron ores
are not found in coal regions. There
s az least one exception to this rule as shown in the
display from the Broad Top coal region--a complete
assortment of ores from Huntington, Fulton and
Bedford counties. believe the largest American
