A first-lieutenant also joined us--Reuben Spry by name,--and two mates, the senior of whom did duty as second lieutenant--Holland and Waller. The very day we were ready for sea we went out of harbour, and made the best of our way towards the coast of Africa. A succession of easterly winds had kept the _Opossum_ more to the west than she would otherwise have been. We were about the latitude of Barbadoes, when, having run on during most of the night with a fair breeze, towards morning it dropped altogether, and we found ourselves rolling away in a tropical calm. As we were already in the seas where slavers are to be found, a bright look-out was kept, in the hopes of our falling in with a prize, though as yet not a sail had been seen to which it was thought worth while giving chase. As morning broke, of a day I shall not easily forget, there appeared to the southward, not four miles from us, two vessels becalmed like ourselves. One, a large barque, somewhat the nearest to us, was clearly an English merchantman; the other, a low, black schooner, had the wicked, rakish appearance of a Spanish slaver. The look-out from the foretopmast-head gave notice at the same time that he could see two boats pulling from one vessel to the other. The captain and all the officers were speedily on deck. "There's some mischief going on there," exclaimed Captain Idle, after a look at the vessels. "Mr Spry, call the boats away; we must send and overhaul these fellows." Three boats, under the command of the first-lieutenant, were speedily in the water, and manned, all hands being well-armed. Waller had charge of one boat, I of the third,--and not a little proud did I feel of the honour. A cup of cocoa and some biscuit being first served out to each of us, to give us strength for the work to be accomplished, away we pulled towards the barque. It was hot enough when we started, but as the sun rose higher it grew hotter still, and the glare on the smooth water became so bright as almost to blind us; but nothing relaxed our exertions, all hands feeling that there was some work before us. The other boats had reached the barque when we were yet three miles off, and very probably had not observed us, although the people from the rigging of the merchantman must have done so. The report of firearms was now heard, and this made us redouble our efforts to get up. "The merchantman is attacked by pirates; there is not a doubt of it," shouted Mr Spry. "Fire off your muskets, my lads; it will give both parties notice that we are coming to put a stop to their fun." Those not pulling blazed away right merrily for a few minutes, and then watched for the result. It seemed to have encouraged one party and to have disheartened the other, for the boats we had before seen were observed pulling back to the schooner.
