THE SAGO PALM.
Both in Redscar Bay and for the first two or three days after leaving it numbers of sago palms, some quite recent, were observed on the water, occasionally with boobies and noddies perched upon them. These trees had probably grown upon the banks of the rivers of the bay, and been washed away by the undermining of the low alluvial banks on which they grow, and carried out to sea by the current. Along several of the freshwater channels on the western side of the Great Bight examined by the Fly's boats in 1844, I had seen this palm growing on the margin of the stream in great profusion, and according to Giaom, the bisi tree (as she called it) is occasionally carried by the winds and currents as far south as the Prince of Wales Islands, when the natives scoop out the soft spongy inner wood, wash it well with fresh water, beat it up into a pulp, separate the farinaceous substance which falls to the bottom of the vessel, and bake it as bread. On no part of the coast of New Guinea, however, did we ever see any of this sago bread, which is known to constitute the principal food of the inhabitants of the north-west coast of that great island.*
(*Footnote. Forrest endeavours to show that an acre of ground planted with 300 sago palms will maintain fourteen men, as each tree produces 300 pounds of sago flour, when arrived at full maturity in its seventh year.

On one occasion lately the water was discoloured by a conferva resembling the sea-sawdust of Captain Cook, with which it was found to agree generically in consisting of long filaments joined together by a softer gelatinous-looking substance. The present species, however, is six times larger than the more common sort, some of which was mixed up with it, their diameters as ascertained by Mr. Huxley, being respectively 8 1/2 over 5000 and 1 1/8 over 5000 of an inch.
Today we stood in for the Duchateau Isles, and, rounding them to the westward, anchored in the afternoon in seventeen fathoms, with the central island bearing south, distant one mile.
SHOOTING PARTY ON DUCHATEAU ISLES.
January 7th.
Along with a shooting party I landed soon after daylight on the westernmost Duchateau Island. Numbers of Nicobar pigeons left the island as we approached, having apparently used it merely as a roosting-place.
HABITS OF DUPERREY'S MEGAPODIUS.
Heavy showers and thunderclouds passed over at intervals during the whole morning, rendering our shooting not quite so successful as it might have been; still we procured about fifty pigeons and a few of Duperrey's megapodius. In habits this last bird resembles the Australian species, especially in constructing enormous mounds for the reception of its eggs. Those which I saw averaged five feet in height and fifteen in diameter, and were composed of the sandy soil of the neighbourhood, mixed up with rotten sticks and leaves, but without any shells or coral. Some were placed on the outer margin of the thickets close to the beach, and others were scattered about more inland. As several of these mounds showed indications of having lately been opened by the birds, I entertained hopes of being able to procure an egg, but after digging several pits three feet in depth, with no more efficient implements than my hands, I had to give up the work from sheer exhaustion. This bird is apparently very pugnacious at times, as I frequently saw them chasing each other along the ground, running with great swiftness, and uttering their cry more loudly than usual, stopping short suddenly and again starting off in pursuit. The cry consists of one or two shrill notes, uttered at intervals and ending in a hurried tremulous cry repeated five or six times. The noise made by this megapodius while scratching among the dead leaves for food may sometimes be imitated with such success as to bring the bird running up within gunshot. When suddenly forced to rise from the ground it flies up into a tree, and remains there motionless, but exceedingly vigilant, ready to start on the approach of anyone, but on other occasions it trusts to its legs to escape. Its food is entirely procured on the ground, and consists of insects and their larvae (especially the pupae of ants) small snails, and various fallen seeds and fruits. Although a great number of the Nicobar pigeons had left, many yet remained, and the whole island resounded with their cry mixed up with the cooing of the Nutmeg pigeon. Little skill is required in shooting these birds, for they generally admit of very close approach, as if trusting to the chance of being overlooked among the dense foliage.
