this four miles will be continuous heavy
rock work, the cuts ranging from 30 to
60 feet in depth. The quantity of rock
and earth to be removed will approx
mate 800, 600 cubic feet and the contract
calls for completion by April l. 1t is
| the intention of the contractors to Sc
cure an entire new outfit and to put on
a new force of about 400 men on this
section This will make force of be-
tween 700 and 800 men on the entire
job.
Along this four-mile extension there
will be two tunnels aggregating 500
feet in length. These tunnels are to
have concrete portals and lining for a
distance of 40 to 80 feet in from each
end. The remaining length of the tun-
nels will be timber lined. There will
also be four steel bridges, which, &C
cording to the contract, will rest on
concrete piers and abutments. The
aggregate length of these bridges will
be about 900 feet and their height va
ries from Is to SO feet. One will cross
The Tia .Iuana river and the other three
are to span Matanuco creek. The fills
will be made from the adjacent cuts
along the four-mile stretch so that no
time will be consumed by long hauls.
The railroad company is receiving
bids now for the erection Of the bridg
es fur this section. The company's
engineers are bNsily engaged prepar-
| ing plans for work ahead and as soon
AS they are ready another contract will
be let for further stretch uf 20 to 30
miles. This fuur-mile contract just
awarded carries the work to point %
miles from San Diego and about IA
miles into Mexican territory.
The first contract covered distance
of IA 40 miles, the second 9 25-100
miles and the third 4 titles The
amount of excavating for each, how
ever, figures the same-tha5 is, 100000
cubic yards. The first contract, as this
shows, was comparatively easy going,
the last being the heaviest yet encoun-
tered. E. j Kallright, chief engineer
in charge of construction, said yester
day that beyond the four miles of heavy
| work for which the contract has just
| been let the work VIII be comparatively
light for distance of Il miles, then
medium heavy for 10 miles and, ,the
next 40 lighter again. The work. in
the Tecate valley, he said, would go
along rapidly until the mountains are
reached, and here the, heaviest work
of the entire line would he encountered.
The mountain section, Kallright stated,
lies about 90 mites out # San Diego.
Tracks have been laid to the Sweet
water river. A bridge at this point
will probably be completed in about
two weeks end then the laying of the
tracks will go On continuously until the
Otay valley is reached, where more
bI idge construction will Ge encounter
ed. Nothing will then delay this line
of work until the first crossing of The
RTia JGena river is reached. This sill
complete the ROAD to distance ofthree
miles east Of Tia Juaha.
