There is a great deficiency of good harbours along the shores of this Lake. On its northern side there are but two places which afford shelter to vessels drawing more than seven feet water, namely, Long Point and Point Abineau; and these only afford a partial shelter. If the wind should shift to the southward whilst vessels happen to be lying under them, they are thereby exposed to all the dangers of a rocky lee shore. On the southern shore, the first harbour you come to in going from Fort Erie, is that of Presqu’ Isle. Vessels drawing eight feet water may there ride in perfect safety; but it is a matter of no small difficulty to get into the harbour, owing to a long sand bar which extends across the mouth of it. Presqu’ Isle is situated at the distance of about sixty miles from Fort Erie. Beyond this, nearly midway between the eastern and western extremities of the lake, there is another harbour, capable of containing small vessels, at the mouth of Cayahega River, and another at the mouth of Sandusky River, which falls into the lake within the north-western territory of the States. It is very seldom that any of these harbours are made use of by the British ships; they, indeed, trade almost solely between Fort Erie and Detroit River; and when in prosecuting their voyages they chance to meet with contrary winds, against which they cannot make head, they for the most part return to Fort Erie, if bound to Detroit River; or to some of the bays amidst the clusters of islands situated towards the western extremity of the lake, if bound to Fort Erie. In going up the lake, it very often happens that vessels, even after they have got close under these islands, the nearest of which is not less than two hundred and forty miles from Fort Erie, are driven back by storms the whole way to that fort. Just as we were preparing to cast anchor under Middle Island, one of the nearest of them, a squall suddenly arose, and it was not without very great difficulty that we could keep our station: the captain told us afterwards, that he really feared at one time, that we should have been driven back to our old quarters.
