Sea puss

Sometimes owing to a peculiar formation of the coast, the waves are brought together in an angle, indenting the shore in such a way that this return flow, or undertow, runs out to sea in a continuous stream, which is called a sea-puss. The sea-puss is of variable width—from twenty or thirty feet to perhaps fifty or a hundred—and its location can generally be recognized by the peculiar roughness of the sea, […] as well as by the fact that the beach opposite to it is channeled by the action of the water. […] Thus is happens that there may exist a strong sea-puss at a certain point one day; and next day, or later in the same day, owing to a change in the tide, the veering of the wind, or the shifting of some sandbar, it may have entirely disappeared.

On the afternoon of the date mentioned the wind was blowing offshore and the tide was running in, forming sea pusses at intervals along the shore. We swam out to where the bar had been. Finding that it had shifted, we turned to come back and found that the ide had carried us into a sea puss, and that we were being swept seaward.
