PNEUMATIC DISPATCH.
very important feature in this plan for elevated rail
ways is the combination Herewith Of the pneumatic dis
patch While it is indispensable that heavy freight and
pa ssenger transit city shall he put upon the
tracks yet it Is necessary that with all rapid pas
seDger routes shall be provided equally quick transmits
sion for package, parcel. express, market and mail
matter This is admirably provided for by
light pneumatic tubes between the tracks ana under the

PECULIAR ADVANTAGES OF An ELEVATED ROAD.
This elevated road Dc built and operated in
narrow street as well "a in broad avenue Columns
should not be placed outside the curb where they will
interfere with carriages, drays, wagons or other We
hcles and the structure should in way be attached
TO buildings along the route Public cOnyeHicnces and
other of the highway will admit of no encroach-
ment abldgmcnt. Any increase OF cost III construct
ing along broad avenue will only arise from additional
%ldth oI tle heht IRON arches spanning "" lO,l"dN;
From the superior sustaining strength Of the arch. ana
with the tracks placed near the columns, this increase

city railway practicable for completion Of orc double
track in twelyemOnth, which will not interfere with
other Of the street during time of construction;
which will afford al all times, without possibility OF long
