Affairs at Fort Pickens.
--A Washington dispatch in the New York Herald, gives the following intelligence purporting to have been received from Fort Pickens:‘ Dispatches were received here to-day from Montgomery, indicating a momentary apprehension of a collision at Fort Pickens. It appears that the commanders of the Brooklyn and Sabine can land no supplies or have any further communication with the shore. There are five hundred Government troops and marines in the various vessels laying off the harbor. Should they disregard this notification and attempt to land, a fight will at once come off.
’ Fort Pickens is invested with thirteen full batteries, including Fort Barrancas and McRae, all of which command Fort Pickens and the offing. Gen. Braxton Bragg is commanding officer of the troops of the seceding States. The Government, it is understood, have this information, and this is one of the subjects which have engaged their attention for the last forty-eight hours.
Rumors are current that the destination of the troops now in Texas, for whom transport ships have been sent, is Fort Pickens. It is known that an officer, with sealed dispatches, is on one of the vessels which left New York the day before yesterday, and another officer was dispatched overland to Col. Waite, commanding the troops in Texas. The vessels had the unusual supply of three months provisions. These movements have been duly telegraphed to Montgomery and Pensacola.
