route from Moreton Bay to Port Essington, in the course of which, but more particularly between the head 
of the Gulf of Carpentaria and Port Essington, the sight and capture of the Emu rie vires f ae 
occurrence ; so abundant in fact was it, that he states that he saw in the hors space of eight miles “ eas 
a hundred, in flocks of three, five, ten, and eyen more, at a time. Dr. Leichhardt mentions that the natives 
on killing an Emu invariably break the wings—why, he was at a loss to conceive, as they could pe aneney 
assist the animal in making its escape, should it survive ; some curious practices also exist with respect to 
this bird among the natives, the particulars of which I have not been able to learn, but I may mention that 
the young men and boys are not allowed to feed upon it. . . . . 
The only vocal sound the Emu has been heard to utter is a low booming or pumping noise, which we 
know is produced in the female by means of the expansion and contraction of a large membranous bag, 
surrounding an oblong opening through the rings of the trachea; but whether this peculiarity of structure 
is also to be found in the male I am not aware. For the loan of some interesting drawings and a specimen 
in spirits of this very singular conformation I am indebted to my friend W. Yarrell, Esq. 
The eggs are six or seven in number, of a beautiful dark green, resembling shagreen in appearance; five 
inches and three-quarters in length by three inches and three-quarters in breadth; they are held in much 
esteem by the natives, who feed upon them exclusively whenever they can be procured. They are merely 
placed in a cavity scooped in the earth, generally in a sandy soil. 
They pair with tolerable constancy, and the male bird appears to take a large share in the task of incu- 
bation. In captivity they speedily become tame and domesticated, and have been bred without difficulty in 
various collections in this country. 
Little or no difference of colour is observable in the sexes, which may be thus described :— 
The entire plumage is of a dull brown, mottled, particularly on the under surface, with dirty grey; the 
feathers of the head and neck becoming gradually shorter, and so thinly placed that the purplish hue of the 
skin of the throat and round the ears is perfectly visible ; irides brown; bill and legs dusky black, 
The young on first quitting the shell have a very elegant appearance, the ground-colour being greyish 
white, with two longitudinal broad black stripes along the back, and two others on each side, each sub- 
divided by a narrow middle line of white; these stripes being continued along the neck without subdivision 
and broken into irregular spots on the head ; two other broken stripes pass down the fore-part of the neck 
and breast, and terminate in a broad band across the thighs.
