Mr. Heyliger, agent at Nassau, writes on the 3d instant (just a week ago), that he is shipping bacon by every steamer (three or four per week), leather, percussion caps, and a large amount of quartermaster’s stores. But the supply of lead and saltpeter is exhausted, and he hopes the agents in Europe will soon send more. About one in every four steamers is captured by the enemy. We can afford that.

The President sent over to-day, for the perusal of the Secretary of War, a long letter from Gen. Howell Cobb, dated at Atlanta, on the 7th instant. He had just returned from a visit to Bragg’s army, and reports that there is a better feeling among the officers for Gen. Bragg, who is regaining their confidence. However, he says it is to be wished that more cordiality subsisted between Generals Bragg and ———, his —— in command. He thinks Generals B——— and C——— might be relieved without detriment to the service, if they cannot be reconciled to Bragg. He hints at some important movement, and suggests co-operation from Virginia by a demonstration in East Tennessee.

It is generally believed that France has followed the example of England, by seizing our rams. Thus the whole world seems combined against us. And Mr. Seward has made a speech, breathing fire and destruction unless we submit to Lincoln as our President. He says he was fairly elected President for four years of the whole United States, and there can be no peace until he is President of all the States, to which he is justly entitled. A war for the President!

November 13th.—No news of battles yet. But we have a rumor of the burning of the fine government steamer R. E. Lee, chased by the blockaders. That makes two this week.

Gen. Lee dispatched the President, yesterday, as follows:

“Orange C. H., Nov. 12th.—For the last five days we have only received three pounds of corn per horse, from Richmond, per day. We depend on Richmond for corn. At this rate, the horses will die, and cannot do hard work. The enemy is very active, and we must be prepared for hard work any day.—R. E. Lee.”

On the back of which the President indorsed: “Have the forage sent up in preference to anything else. The necessity is so absolute as to call for every possible exertion.—Jefferson Davis.”

Perhaps this may rouse the department. Horses starving in the midst of corn-fields ready for gathering! Alas, what mismanagement!

I cut the following from the Dispatch:

“Flour.—We heard yesterday of sales of flour at $110 per barrel. We do not, however, give this as the standard price; for, if the article was in market, we believe that even a higher figure would be reached. A few days since a load of flour was sent to an auction-house on Cary Street to be sold at auction. The proprietors of the house very properly declined to receive it, refusing to dispose of breadstuffs under the hammer, where men of money, and destitute of souls, would have an opportunity of buying it up and withdrawing it from market.
