their passion, but not generally using their feet, as they do when wounded. The hens secured by each of the cocks lay together in a mere depression in the soil with very little, if any, lining; the eggs numbering from twenty to thirty, or exceptionally more, besides those scattered about outside the nest. Here again Mr. Hudson is our authority for stating[20] that the eggs of _R. americana_ are golden yellow when fresh, those of _R. darwini_ deep rich green; both however fade quickly to a whitish colour. The male incubates very closely for about six weeks, often taking up his position, as the Ostrich does, before the final egg is laid; he afterwards attends upon the young, and charges intruders who seem dangerous, with outstretched wings and beak. Rheas may be captured by riding after them in a semicircle, which closes upon them as they go, or by means of long-winded hounds; but the most usual method is that of hurling the "bolas" or leaden balls connected by leather thongs, which wind around the bird's neck or legs, and thereby hamper its movements or throw it down. The feathers, though inferior to Ostrich plumes, are much used for brooms and the like, and are said to be called "Vautour" in the trade. The flesh is very poor. These birds have bred both on the Continent and in Britain. III. MEGISTANES. The MEGISTANES comprise the _Casuariidae_ or Cassowaries, and the _Dromaeidae_ or Emeus, the following being the chief peculiarities of the group. The wings are quite rudimentary; {33}the aftershaft of the contour feathers is extremely large, so that they appear to be double; three front toes are present, with shortened mid-phalanges and large claws; and the two clavicles do not meet. The lack of ornamental wing- or tail-plumes, and the hair-like nature of the coat is also characteristic, while, as opposed to _Rhea_, there is no indication of syringeal muscles. Within the group itself the Cassowaries are distinguished from the Emeus by the points next to be mentioned. The former have a compressed keeled beak and a large casque of bony tissue upon the bare head, the greater part of the neck being also naked and in most cases wattled; the remiges are reduced to thick black barbless quills from four to six in number, and the inner toe has a particularly long sharp claw. Emeus, on the contrary, have a broad depressed beak, short feathers on the head and neck, no helmet, wattles, or spines on the wing, and an ordinary claw on the inner toe. Both Families have long necks, stout metatarsi covered with coarse roundish scales, and toes padded below; the tibia being nearly, if not quite, covered by the plumage.
