I am assured by a member of the General’s staff that a naval expedifc on, frited out in great part at New York, is already on the way, destined to attack that place, also Tampic o, 150 miles down the Gulf coast. This will give tt te combined forces of the Liberals and Americans as a water base the Rio Grande, and with Matamoras « * * base of supplies; and it is intended to march on Monterey, and thence, if success should attend themthus far, to the City of Mexioo itself.

She is an ordinary river steamboat, with a slight fender across her bows, to break back the sea. It was a daring deed to put out into the tempestuous gulf, on a voyage of five hundred miles, m such a craft.The current over the bar is rapid, and, being met by the waves of the gulf, is kept in a perpetual ferment, reudering it very dangerous to cross.

'The Ranchero has devoted all its editorials to the Aubject, for two days past, alternately sneering at ♦•General” Crawford, insulting General Weitzel, and ©ailing on the United States to suppress the “fili-buster and nip the plot in the bud.

It winds up a long article this morning by say-mg, “It is safe to conclude that, as long as there is any thing In this country to steal, there will be filibuster organizations on the other side.”Meantime, recruiting under this order has progressed rapidly, so I am assured. Some days ago 42olone! Reed, Chief of staff to General Crawford, published the following notice: \41FIFTY DOLLARS A pONTH IN GOULD,“And all expenses paid. Clothing.

Beside tbose, there are in the neighborhood •bout 2,000 more irregular squads. So closely do these keep the lines drawn about the city that the Imperialists never venture out above five miles be-areare all very small, and at least half of them have a little cupola on top. with a^tairway leading to them over the roof. These are for the inhabitants to take a morning airing in—a very neeafiil affair in the*l«9e, muggy atmosphere of the summer months inthis latitude. TClarksville stands opposite, and is 'still more wretched—the only thing that redeems it from utter contempt is the abundance of American flags that wave over it, as in defiance to the mongrel bunting of the opposite shore. Every thing else looks strange, l roreign.

This is only one of the several branches l»y a hich it is discharged, beside it has, at this poi nt, a very rapid current. It is said to be one of the xapldest rivers of the United States.

The soil, for ten or fifteen mile** up the nver, is a dead level, interspersed with ooonsionaJ ridges of sand that seem to have been the dividing lines between lagoons that, in. remote times, stiretched over the surface. For several miles back from the ooast of the gulf, it is largely composed of sand, and is covered with nothing l?ut the most stsnted shmbbery and weeds; gradually the shrubs increase in .size, indicating a greater proportion of alluvial matter, aud here a few trees reach a hight of twenty-five or thirty feet.
