RAPID TRANSIT RUNBLINGS.
HOW to Lessen the Noise Still
the Puzzle.
EDISON'S EXPERIMENTS.
Ekc.ion of Directors by The Metropolitan
Railway Company

Professor Edison again at his work on the Metro
peInan Elevated Railway yesterday, making expert
nents and carefully noting their results He rode up
md down The road several times with his assistant and
occasionally aigned At stations al which he marked
the vibrations caused by the passing traius HIS note

''As rapidly possible. 1t will now be ready in
DAY or two"
The Professor then entered into q de4aacd de.
scription OF tho working OF the Instrument 1t
Will be placed operation at varioas parts
OF the road and also In the stations
and Immediately under the structure. All tho
sounds from whatever cause produced by the trains,
will be recorded IN minute dots similar 10 these made
on the lin o OF tbs pnonograpn by the vibrations oi
tie membrane with the exception OF tnesc being more
Irregular, owing to the variety OF sources causing
them
aow THE ANALYSIS Is MADE.
H. for instance, the Professor desires to aicertain
the percentage oil noise caused by ering OF
TRUCKS the JOINTS OF mo rails viii lace the
Instrument IN a proper position, and, watcnDg the
particular cause, make series oi

readily be compared with All the others In his way
The percentage Of every sound on the road will be
anayZod, measured and ~ ,mpared

The experiments thus far by the r eofessor
