THE AVONDALE MARBLE.

Philadelphia Ledger.
For several years persons interested Ii
the stone quarrGs ut Avondalg, Cheste
county, have thought from the geological
formation of the contiguous earth. tina
there was bed of marble underlying til,
limestone strata, and it was believed tina
the mineral was of superior quality. Thi
representation has been C0rroboratcd by
AN investigation Of one of the most emf
hent living biologists, Professor Koeng
chiei OF the Michigan Mining School, wht
recently visited Avondalc, and the result
OF whose examination was briefly men
toned at the time in a dispatch to tho
Lo3cr. While the professors inspection
was but clirsory it absolutely confirmed
the belief that test by boring would de
velpp either the limit of the quarry or q
bed OF very fine stone. The modern dia.
mond drill has been utilized at several
points III the quarry, and, after passing
through several grades OF excellent build
ing and bridge stone, the resultant Gore
shows marble OF n better quality than the
Georgia marble Of commerce., and finally
4 strata was encountered which. after OK,
haustive tests, has been pronounced by
eminent authorities statuary marble equal
10 the best tRrrura stone. The drill fol.
lowed this vein 30 feet, when operations
were suspen led on account of the Difficult
ties encountered from freezing weather
How much deeper the vein goes is
not yet known, it has already been de.
inon-trated that il is at least - feet thick
