From the Bay of Aransas. — The U. S. transport steamboat Monmouth, Capt. Baker, arrived here yesterday forenoon from Aransas Bay.  She left there on the 16^th inst., arrived at Galveston on Friday night, and departed again on Monday night, the 20^th, and made her way hither, against N.N.E. winds, which prevailed throughout the passage.

 

The Monmouth is in a very critical state, leaking most rapidly, and will go at once into dry dock for repairs.

 

The army at Corpus Christi was in pretty good health, except that a few cases of dysentery had occurred.  Three hundred Mexicans ventured within 50 miles of Corpus Christi a few days since, in pursuit of a body of Camanches, which had been committing depredations on the settlements.  The commander of the Mexicans, being an old acquaintance of Col. Kinney, sent word to him that he should have called to see him, but was fearful he might be censured.  An old friend in the army writes us as follows on this subject:

 

7^th Infantry Camp, Corpus Christi, Texas

October 15^th, 1845.

 

My Dear Sir — I wrote you by the Alabama, since which nothing of import has transpired.  Yesterday Madam Rumor circulate d a report that 300 Mexican soldiers were within 60 miles of Corpus Christi.  I inquired in relation to this rumor, and find that there are a few small posts occupied by the Mexicans on this bank of the Rio Grande.  In the vicinity of Mier, for instance, there are about 100, near Loredo about 100, and near Camargo about 100.  The Camanches came down in the vicinity of that portion of the frontier and committed depredations, killing and stealing.  The troops from the neighborhood of the different towns mentioned started out in pursuit in three detachments, (about 100 each,) and are now on the war trail.  This is nothing unusual as I learn from Col. Kinney.

 

Whether Gen. Taylor will or will not take any action upon this, is yet to be determined.

 

The steamer Monmouth goes over for repairs.  She will return here again.  Capt. Blake’s party has not yet returned.

Very truly,

 

The party under Capt. Blake had been previously sent out on a reconnoissance, we believe.  We have no further intelligence whatever as to the army by this arrival.
