I can cite plenty of authority for this statement. There is, in particular, no less a personage than “Robert Tanner, Gent. Practitioner in Astrologie and Physic.” “The cranes,” he writes, “when they fly out of Cilicia, over the mountain Taurus, carried in their mouths a pebble stone, lest by their chattering they should be seized upon by eagles.”
The cranes had yet another use for their stones. When the main body were resting at night, sentinels were posted to guard against surprise, so that the company could go to sleep in security. To ensure necessary vigilance, the sentinels stood on one foot and held in the other a large stone. If they inadvertently nodded, their muscles relaxed and the stone dropped. This, of course, used to wake them up. Even Alexander the Great was glad to learn a lesson from the cranes. He used to go to roost with, not a stone in his hands, but a silver ball, as more befitting his royal dignity. On the slightest movement the ball would fall and he wake up. Thus it was that he never overslept himself. We do not do such heroic things nowadays; nor do cranes.
Cranes are birds which will not stand nonsense. The pigmies used to go egg-collecting among them; the result of this was, to translate Homer:—
When inclement winters vex the plain,
With piercing frosts, or thick descending rain,
To warmer seas the cranes embodied fly,
With noise and order, through the midway sky:
To pigmy nations wound and death they bring.
Notice that as the cranes were on the war-path there was no necessity for them to fill their mouths with stones; they wanted all their lung power to bark at their pigmy foes.
Having considered cranes as they are not, it behoves us to glance at them as they are. The sarus is a handsome creature. It stands over five feet high. The general colour of the plumage is a beautiful French grey. The head and long neck are devoid of feathers, but are covered with numerous tiny crimson warts or papillæ. These assume a deeper hue at the breeding season, which occurs from July to September. There is a patch of grey on the sides of the head. The throat and a ring round the nape are covered with black hairs.
