This afternoon we set up the Observatory and took the Astronomical Quadrant ashore for the first time, together with some other Instruments, the fort being now finished and made as Tenantable as the time, Nature, and situation of the Ground and Materials we had to work upon would admit of. The North and South parts consisted of a Bank of Earth 4 1/2 feet high on the inside, and a Ditch without, 10 feet broad and 6 feet deep; on the West side facing the Bay a Bank of Earth 4 feet high, and Palisades upon that, but no Ditch, the works being at high-water mark. On the East side upon the Bank of the river was placed a double row of Casks, and, as this was the weakest side, the 2 four Pounders were planted there, and the whole was defended, beside these 2 Guns, with 6 Swivels, and generally about 45 Men with small Arms, including the Officers and Gentlemen who resided ashore. I now thought myself perfectly secure from anything these people would attempt.
