Honorable E. M. STANTON,

Secretary of War:

The following dispatch just received:

PITTSBURG, 28th.

Governor CURTIN:

An express messenger from Morgantown, by express train from Uniontown, arrived here at 2 o'clock this morning, with intelligence that 4,000 rebel cavalry were within 2 miles of Morgantown at 2 o'clock yesterday, coming into Pennsylvania. The Baltimore and Ohio Railroad, between Grafton and Cumberland, is torn up.

All the foregoing is confirmed by intelligence from Wheeling. We are without arms, artillery, or ammunition here. What can you do for us?

THOMAS M. HOWE,

Assistant Adjutant-General, Pennsylvania.

Have you any information? If it is reliable, what force, if any, can you oppose to the rebels? We have no force in the State of any kind, as you are aware. Be pleased to telegraph me as soon as possible, as there is much alarm in this part of Pennsylvania threatened.

A. G. CURTIN,

Governor of Pennsylvania.
