'They live on fish of various kinds. I have found the backbones of fish 2 feet in length. The eat leather-jackets, parrot fish, squid, &c. I found one backbone 2 feet 4 inches; it may have been a barracuta or pike; I don't think it was a shark. I have found a few joints of a shark's backbone.

The bull is very furious at pupping season, and when disturbed will go into the water and return in a few minutes. Out of season they go to sea in the morning and return at night. When fighting they strike each other like the boar; their teeth are about 1½ inches long, and cut terribly. I have seen cuts from 1 to 10 inches in length.

The usual color is a yellowish-brown, although some have been seen that were spotted, and some a beautiful grey.

They generally select flat, inaccessible rocks, or, where they are not disturbed, they select the grassy patches.

The cow generally brings forth one pup, sometimes two. They keep good watch, and care affectionately for their offspring. They circle round them in rough stormy weather, and keep them from any wash or sea that may come over the rocks. I have seen three pups washed off the rocks, and the cows have immediately followed and brought them on the rocks again in an astonishingly rapid manner. I have also seen them catch a pup in their mouth, and throw them 10 feet high, and never hurt them.

Their sight is not so good, so it is generally said. I think, myself, their sight good enough, but they not smelling man don't think he will harm them; when they get the least scent they are off like a shot.

I consider them as quick in their movements as any fish that swims. They strike at one another with the rapidity of lightning. I have seen one bull prevent another from landing for several hours. They move along by drawing the hinder part of the body forward and under, and then giving a jump and push forward.

All I write is my experience on the Seal Rocks, off "The Nobbies," at Phillip Island, Victoria.'
