36 and on South Trinidad Island, were skinned and made up into museum specimens. They were also examined for external and internal parasites by Wilson, Atkinson and myself, as were also such fish and other animals as could be caught, including flying fish, a shark, and last but not least, whales in New Zealand.

The method of catching these birds may be worth describing. A bent nail was tied to a line, the other end of which was made fast to the halyards over the stern. Sufficient length of line was allowed either to cause the nail to just trail in the sea in the wake of the ship or for the line to just clear the sea. Thus when the halyard was hoisted to some thirty or forty feet above the deck, the line would be covering a considerable distance of sea.

The birds flying round the ship congregate for the main part in the wake, for here they find the scraps thrown overboard on which they feed. I have seen six albatross all together trying to eat up an empty treacle tin.

As they fly to and fro their wings are liable to touch the line which is spread out over the sea. Sometimes they will hit the line with the tips of their wings, and then there is no resulting capture, but sooner or later a bird will touch the line with the part of the wing above the elbow-joint (humerus). It seems that on feeling the contact the bird suddenly wheels in the air, thereby causing a loop in the line which tightens round the bone. At any rate the next thing that happens is that the bird is struggling on the line and may be hauled on board.

The difficulty is to get a line which is light enough to fly in the air, but yet strong enough to hold the large birds, such as albatross, without breaking. We tried fishing line with no success, but eventually managed to buy some 5-ply extra strong cobbler's thread, which is excellent for the purpose. But we wanted not only specimens, but also observations of the species, the numbers which appeared, and their habits, for little is known as yet of these sea birds. And so we enlisted the help of all who were interested, and it may be said that all the officers and many of the seamen had a hand in producing the log of sea birds, to which addi-
