"pectoral and pelvic fins may be set as sails while the tail is still lashing the water. They remind me much of a hydroplane 'getting up'. Sometimes when they are soaring and drop to the water they will again move the tail and leave the surface for a continued sail. Then seem to go in schools 3 or 4 often getting up close together. The petrels are acting as before and we usually have a few Albatros about. Towards evening we saw some birds flying off at a distance - single or in pairs. They were gray above and shone silvery white beneath. They flew with rapid wing beats up and down over the swells. - Probably Skylits or Murrits. A good deal of sea weed was sun floating. No whales, porpoises or the like have been seen so far. June 23. Tue The petrels were with us before but the Goose left as we came near Cape San Lucas
