THE MECHANICAL BAKERY IN PHILA-
DELPifI4.

Aya,t baking establishment has been constructed
in Philadelphia using the mechanical ovens and other
machinery of Mr.. H. Berdan of this city. 1t was in
ougurated on Thursday, in the presence Of a large
| number Of prominent gentlemen. The works were in
complete operation, and the processes were exhibited
| and explained collation. then given, in which

can the allowing brief report Of the remarks Of Mr.
| Harrison:
During thc progress Of constructing this great
tabsbment he MR. H. had been frequently about,
watching the Of events and examining into the
principles upon which the various parts were based
and he could say that in every respect it W.. an adj
mirable combination Of machinery, such a. Mr. Ber-
| dan might well be proud of. lie regarded ne man
who could invent anil a9hi~v" an undertaking ik. The
as n true hero He had overcome more difficulties,
md was in fact surrounded by real poetry and
| romance than many knight who figured in chval-
rous story song. And who shall say that there IL
not poetry and romance in machnery-poctry in the
glow Of the great furnaces, in the whrr OF the obe-
dcut wheels which uuerrngly do their afOtted work,
| in the gsteni~g blades of the cutting machine, aud
the slow but majestic roll of the patent kneader The
machniss Of modern times had accomplished Tor So
cety more Of true progress than the world ever knew
before and foreul"s. among these Mr.. Berdan would
| be- Chased"
