These birds emigrate from one tropical country to another; and during a passage from Manilla to Singapore, through the China sea, on the 20th of October, 1830, for several days a number of these birds were flying about the ship; and I am inclined to suppose, derived at that period sustenance from the flies which infested the ship, as soon afterwards but few of those insects remained. In the evening they would roost on the rigging; and some even took refuge for the night in the chief officer’s cabin, which opened upon the deck, and were again set at liberty in the morning. They became after a few days exhausted; several were found dead, and others became so tame from fatigue and hunger, as to be easily caught, and would afterwards remain perched on the hand, without making any effort to regain their liberty. These were also of the species _Hirundo rustica_ of Linnæus, which is widely distributed over the globe. We first observed them in latitude 15° 29′ north, and longitude 117° 40′ east; and we lost them, most having perished, in latitude 9° 30′ north, longitude 110° 45′ east, having been about the ship for thirteen days. The question that arises is, whether in the latter instances they were emigrating, or had been blown off the land by the westerly gales we had experienced since leaving Manilla Bay. It may be mentioned, that as we had at the same time numerous other land birds about the ship, the latter supposition is not improbable. After having been detained for several days by easterly winds, on the 29th of April we had fair breezes,—the swallows then departed, perhaps as glad as ourselves at having some chance of terminating a long voyage. We made the Scilly Islands on the 30th, and arrived at Gravesend on the 5th of May, 1834. APPENDIX. THE COCOA-NUT TREE.
