_June 17._ A brig bound to Boston, called the "Andromache," came alongside, and my heart rejoiced at the idea that letters could be carried by her to America. I set to, and wrote to my wife and to Nicholas Berthoud. A sudden squall separated us till quite late, but we boarded her, I going with the captain; the sea ran high, and the tossing of our light yawl was extremely disagreeable to my feelings. The brig was loaded with cotton, extremely filthy, and I was glad to discover that with all _our_ disagreeables we were comparatively comfortable on the "Delos." We have been in sight of Cuba four days; the heat excessive. I saw three beautiful White-headed Pigeons, or Doves, flying about our ship, but after several rounds they shaped their course towards the Floridas and disappeared. The Dolphins we catch here are said to be poisonous; to ascertain whether they are or not, a piece of fish is boiled with a silver dollar till quite cooked, when if the coin is not tarnished or green, the fish is safe eating. I find bathing in the sea water extremely refreshing, and enjoy this luxury every night and morning. Several vessels are in sight. _June 26._ We have been becalmed many days, and I should be dull indeed were it not for the fishes and birds, and my pen and pencil. I have been much interested in the Dusky Petrels; the mate killed four at one shot, so plentiful were they about our vessel, and I have made several drawings from these, which were brought on board for that purpose. They skim over the sea in search of what is here called Gulf Weed, of which there are large patches, perhaps half an acre in extent. They flap the wings six or seven times, then soar for three or four seconds, the tail spread, the wings extended. Four or five of these birds, indeed sometimes as many as fifteen or twenty, will alight on this weed, dive, flutter, and swim with all the gayety of ducks on a pond, which they have reached after a weary journey. I heard no note from any of them. No sooner have the Petrels eaten or dispersed the fish than they rise and extend their wings for flight, in search of more. At times, probably to rest themselves, they alighted, swam lightly, dipping their bills frequently in the water as Mergansers and fishy Ducks do when trying, by tasting, if the water contains much fish. On inspection of the body, I found the wings powerfully muscular and strong for the size of the bird, a natural requisite for individuals that have such an extent of water to traverse, and frequently heavy squalls to encounter and fight against. The stomach, or pouch, resembled a leather purse of four inches in length and was much distended by the contents, which were a compound of fishes of different kinds, some almost entire, others more or less digested. The gullet was capable of great extension. Fishes two and a half inches by one inch were found nearly fresh. The flesh of these Petrels smelt strong, and was tough and not fit to eat. I tasted some,
