running in before another to run with safety between La Gallaguilla and
La Blanquilla as soon as the Lavendera light is seen between the other
two.

The width of deep water at the entrance between the Lavendera and Hornos
reefs will be 1,000 ft. The estimated cost of these extensive works is
ten millions of dollars, a large sum for the Mexican Republic to expend
in harbor improvements at one port but it will doubtless be found a
profitable investment as it will tend greatly to promote trade, and so
increase indefinitely the commerce of the port.

Mr. Eads' plan having been approved by the Mexican Government the work
was formally commenced on the 14th of last August. Plans were also
furnished by him at the request of the Government, for deepening the
mouth of the Panuco River upon which is located the city of Tampico, the
Gulf terminus of the Mexican central railway system.--_Engineering._

attendance etc., but is nevertheless of interest.
