[Boston] Apl. 11th 
The Admiral gave orders to all the ships at Boston not to suffer any Stock to be taken off the Islands in the harbour without permission, and as the situation of things became more and more critical, and he was sollicited to guard Boston against any attempt from Charles Town side, he caused the channel of the [Charles] river to be sounded, and, finding there was room enough for a large ship to swing at low water, ordered Captain [Edward] Le Cras to place the Somerset exactly in the Ferry way between the two towns, which he accordingly did.
