On James Island a party of fifty men are at work extending and enlarging the mortar battery at its right flank. This is evidently to be so enlarged and furnished with guns as to constitute the strong point on which rests the left flank of the line of entrenchments which covers Fort Johnson, and perhaps the city on that side. In this fort, the splinter-proof traverses being completed and the parade well cleared, the men are at work hosting to the terre-plein the 32-pounder chassis, to be used for temporary traverses between the guns.
I have the honor to be, very respectfully, your obedient servant,
J. G. FOSTER,
Captain of Engineers.

Colonel L. THOMAS, Adjutant-General U. S. Army:
COLONEL: I have the honor to report that we do not see any work going on this morning. Yesterday, in consequence of the members of the Convention coming down, a great deal of firing of shot and shell took place at Fort Moultrie and from the batteries on Morris Island.
The three batteries outside of the Star of the West have certainly guns of very heavy caliber; this we know from the great extent of the ranges and from the reports.
As our provisions are very nearly exhausted, I have requested Captain Foster to discharge his laborers, retaining only enough for a boat's crew. I hope to get them off to-morrow. The last barrel of flour was issued day before yesterday.
I am, colonel, very respectfully, your obedient servant,
Major, First Artillery, Commanding.
