One portion of an egg which he found was large enough to enable him to calculate the size of the egg when complete. "As a rough guess, I may say that a common hat would have served as an egg-cup for it: what a loss for the breakfast-table! And if many native traditions are worthy of credit, the ladies have cause to mourn the extinction of the Moa: the long feathers of its crest were by their remote ancestors prized above all other ornaments; those of the White Crane, which now bear the highest value, were mere pigeon's feathers in comparison." The total number of species of Moa once inhabiting New Zealand was probably at least fifteen, and, judging from the enormous accumulations of their bones found in some districts, they must have been extremely common, and probably went about in flocks. "Birds of a feather _flock_ together" (proverb). It is justly concluded, both from the vast number of bones discovered, and from the fact of their great diversity in size and other features, that they must have had the country pretty much to themselves; or, in other words, they enjoyed immunity from the attacks of carnivorous quadrupeds. In whatever way the Moas originated in New Zealand, it is evident that the land was a favourable one, for they multiplied enormously, and spread from one end to the other. Not only was the number of individuals very large, but they belonged (according to Mr. F.W. Hutton) to no less than seven genera, containing twenty-five different species, a remarkable fact which is unparalleled in any other part of the world. The species described by Professor Owen in his great work,[75] vary in size from 3 ft. to 12 or even 14 ft. in height, and differ greatly in their forms, some being tall and slender, and probably swift-footed like the ostrich, whilst others were short and had stout limbs, such as Dinornis elephantopus (Fig. 56), which was undoubtedly a bird of great strength, but very heavy-footed. Dinornis crassus also had stout limbs. (See Plate XXIII.) [75] Memoir on _The Extinct Wingless Birds of New Zealand_. London, 1878. The beautiful drawing by Mr. Smit (Plate XXIV.) is from a photograph in this valuable work representing the late Sir Richard Owen standing in his academic robes by the side of a specimen of the skeleton of the great Dinornis maximus.
