WORK IN VICINITY OF FRIJOLES.

In order to get work started as far Hon Awana. from the completed
section north of Gamboa as possible, a connection track a little over a
mile long was built from the old station of Frijoles up the Frijolito |
River Valley till it reaches the relocated line. Permanent track has
reached a point 3 miles north of this junction and about a mile south
of the Bohio Ridge. The cuts have been excavated for a mile in
advance of the track, and track will advance as rapidly as a track
pile driver can build temporary trestles across the numerous streams.
There remain at the close of the fiscal year 8 miles of such track to
be laid from the north end of the work at Frijoles to the south end
of the work at Gatun. A little over 1 mile of that distance is already
graded south of the Gatun River crossing. About 24 miles will have
to be built by first driving pile trestles. The remainder is to be
built by taking out the cuts by hand ahead of the pile driver and
driving trestles across the intervening gullies.

WORK ON THE CAIMETO SECTION.

Caimeto is 5 miles north of Gamboa and 5 miles south of Frijoles.
At the close of the fiscal year, June 30, 1908, the north end of the
track from Gamboa was about a mile from Caimeto. During the
present fiscal year trestle was driven across a 4,000-foot valley, which
made up the greater part of this mile. Track was laid through the
intervening cut, which was taken out by hand. Excavated material
has been hauled by the Isthmian Canal Commission from the Culebra
cut across the Gamboa Bridge, and this trestle, as well as all of the
other large trestles, lying immediately north of Gamboa for a dis-
tance of 6 miles have been filled. At the same time work has been
carried on northward from Caimeto toward Frijoles, and there
remains a gap of about a mile between the north end of track on that
section and the south end of track on the Frijoles section.

MIRAFLORES TUNNEL,

At the beginning of the fiscal year, excavation of the tunnel bore
had been practically completed and temporary timber lining had
been placed through nearly the entire length. The north 400
_ feet of the tunnel passes through solid rock and the south slope.
