or that one wing of their army has been defeated and driven into
Mexico.

President Diaz does not, however, intend to allow the rebels to use his
country as a refuge, and he is sending forces to the frontier to drive
them back into Guatemala, to be captured by Barrios.

An interesting sham fight took place in Van Cortland Park last week.

The soldiers were divided into two forces, the attacking and the
defending, and the object of the fight was to see what the commander's
idea of defence would be, in case an enemy attacked the city.

A number of officers from the regular army attended the fight, and
praised our citizen soldiers in high terms for the excellent work they
did during the action.

The attacking party came up from the banks of the Hudson River at
Riverdale, and endeavored to steal down the high-road to Kingsbridge,
where they could cross over the Harlem River, and so find themselves on
Manhattan Island, with the upper part of New York city at their mercy.

The defenders divided their forces into two divisions,--the army of the
West and the army of the East: the one to check the invaders if it was
their intention to march across the country to New Rochelle, and the
other to prevent any attempt to reach New York city.

The general of the defending army took up his position on Woodlawn
Heights, where he could see just which way the attacking army was going
to move; and finding that the attempt was to be made on New York, sent
troops to the roads and the fields through which the invaders must try
to pass.

So well did he lay his plans that the invaders found themselves checked
at every point. There was not a loophole left unguarded for them to
creep through, and at last, after much good generalship had been
displayed on both sides, the invaders were driven back, and the
defenders claimed the victory.

The sham battle was followed by a review of the troops engaged, and when
it was all over the citizen soldiers returned to the city, tired and
dusty, but proud of their good day's work.

INVENTION AND DISCOVERY.

An interesting advance in the postal system of our country was made
recently when the first of the pneumatic tubes which are to carry mail
underground from one office to another was declared ready for use.

Some three hundred prominent men were present to see the first packa
