too soft nature for the maintenance
Of a pile trestle, and the described
method was adopted only after several
other schemes had failed; the second
Ill was over deep gorge with good
solid foundations, and the galloway
was adopted primarily because il
seemed to be the cheapest and most
efficient mtehod.
About 25 miles south Of Cleveland
the line Of the new railroad
crosses a swamp on an embankment
from 25 to 80 feet high and one and
one-fourth miles in length. The bot
tom lands across which the line Is To-
Gated are used for raising celery and
are oyerlaid by a black. decomposed
vegetable soil. incapable OF sustaining
any material weight Soundings
showed the greater part Of the ground
to have a mud crust about is feet thick
then quicksand for Is feet, then ten
feet Of soft clay everything the hard
blue-cIay bottom. AT intervals the
mud crust was only Is feet thick, and
under it was heavy underground
stream flow SO great that the water
spurted several feet out Of the sound
ing pipes. These subterranean lakes
we're so numerous as to make imprac-
ticable the ordinary methods Of fill
ing
Two unsuccessful attempts at cross
ing were made; one by laying track
on a trestle built on a foundation Of
crossed timbers and brush, and anoth-
er BY constructing a pile trestle on the
ordinary plan In both cases the
track sank into the mud, and the cable
scheme was tried as a last resort. Says
the writer:
1.-TWO neutrality-suspicious. steel
cables. about five feet center to cen
ter, were stretched from an anchorage
IN the fill already made, over the near
est bent Of the pile trestle remaining
and on to the farther bents, to which
the other end was anchored Upon
these cables ties were fastened,
ana track laid, upon which the
loaded cars were pushed and dumped
one at a time, at the end of the fill
The first span used was over 200 feet
covering the hole into which the tres
tie had sunk and which was at this
time a pond OF water 175 long and IA
feet deep. On account Of the large
span made necessary by the impossi
bility Of driving a trestle bent in thi.
pond. the sag in the cable was very
great. and the instability Of the cari
quite marked. This, together viii
the great depth Of the fill, necessitatet
the constant iacking OF the track IN
der the All.
AS soon as this sinkhole wal
crossed large trestle bent wa
erected, and the long span decreased
by guy supports and timber grillag
blocks. The material deposited in thi
hole G25.oOO cubic yards in month
showed ahead and completely carries
away the remaining portion Of the pill
tresile which was serving as forwar
anchorage for the galloway. Timbe
towers we're then built ahead an
