Getting under weigh from Swanage, we stood round Peveril Point and Durlestone Head.  The wind being off shore, we kept close in with the coast, which consists of high cliffs full of fossils, we were told.  As we were passing Saint Alban's, or Saint Aldhelm's Head, we got out our mackerel lines.  We had half a dozen each, about forty fathoms long.  To each line were fastened eight or ten snoods: a snood is a short line with a hook at the end.  At first we baited with pieces of white linen, as the mackerel is a greedy fish, and will bite at any glittering object in the water.
