At this state of the tide, which happens twice in a day and night, vessels can enter or go forth.
The Irish ships, of which I have spoken, thus come into the Lake, waiting outside the bar till the tide lifts them over.

The Irish ships, being built to traverse the ocean from their country, are large and stout and well manned, carrying from thirty to fifty men.

The Welsh ships, which come down from that inlet of the Lake which follows the ancient course of the Severn, are much smaller and lighter, as not being required to withstand the heavy seas.

They carry but fifteen or twenty men each, but then they are more numerous.

The Irish ships, on account of their size and draught, in sailing about the sweet waters, cannot always haul on shore at night, nor follow the course of the ships of burden between the fringe of islands and the strand.
They have often to stay in the outer and deeper waters; but the Welsh boats come in easily at all parts of the coast, so that no place is safe against them.
