“You have done well, lads,” the captain said, as they were at dinner on the evening before sailing. “You must not expect to make a very great deal by your trading, although, no doubt, you will get a handsome return for your money. To do really well you must have some knowledge of what birds are rare and what are common, and I should advise you when we get home to spend any time that you have to spare in visiting the Museum and examining the birds there. No doubt you will be able to find out from one of the attendants which are rare ones, and might be able to consult some books on the subject. You may have the luck to come across skins that are altogether new; and, at any rate, a little knowledge would enable you to exchange your goods to a very much greater advantage than you could otherwise do. A knowledge of that kind is always useful to a sailor, who in his wanderings may well get from the natives rare and valuable specimens in natural history, and there are always plenty of collectors ready to pay good prices for them. I have often regretted that I did not pay attention to such matters when I was young; for besides paying well, it gives a great interest to visits to little-known places, and I have heard of two or three captains who have made a good deal of money by it.” For two months after getting among the islands no serious adventures were met with. Trading went on steadily. Several times large native craft were seen, but these sheered off when they saw that the _Tiger_ was well armed and prepared for defence. As most of the places touched at had been visited by the captain on previous voyages, the natives hailed his return with expressions of apparent pleasure; but however friendly their bearing, there was never any abatement of the vigilance by the captain and his officers. Only a certain number were allowed to come on board to trade. The seamen always carried cutlasses by their side and a brace of pistols in their belts, and even when they went ashore for wood or water two boats were always sent, half the men with loaded muskets keeping guard while the others worked, and the guns of the ship were loaded and trained in readiness to open fire in case of any hostile demonstration on the part of the natives. Occasionally, when a chief had paid a visit to the ship and invited the captain to a feast on shore, a strong guard armed to the teeth accompanied him, and a boat lay by the ship’s side in readiness to land another party if necessary.
