When a skilful thrower takes hold of a boomerang with the intention of throwing it, he examines it carefully (even if it be his own weapon, and if it be a strange weapon still more carefully), and, holding it in his hand, almost as a reaper would hold a sickle, he moves about slowly, examining all objects in the distance, heedfully noticing the direction of the wind, as indicated by the moving of the leaves of the trees and the waving of the grass, and not until he has got into the right position does he shake the weapon loosely, so as to feel that the muscles of his wrist are under command. More than once, as he lightly grasps the weapon, he makes the effort to throw it. At the last moment, when he feels that he can strike the wind at the right angle, all his force is thrown into the effort: the missile leaves his hand in a direction nearly perpendicular to the surface; but the right impulse has been given, and it quickly turns its flat surface towards the earth, gyrates on its axis, makes a wide sweep, and returns with a fluttering motion to his feet. This he repeats time after time, and with ease and certainty. When well thrown, the farthest point of the curve described is usually distant one hundred or one hundred and fifty yards from the thrower. It can be thrown so as to hit an object behind the thrower, but this cannot be done with certainty. The slightest change in the direction of the wind affects the flight of the missile to some extent; but the native is quick in observing any possible causes of interference. The northern blacks are the southern blacks, but are 'much more so.' They are finer and fiercer men; more given to slaughter, building better houses, more intractable. The engraving on the next page depicts an encampment of blacks on the shore, at the mouth of Wreck Creek, Rockingham Bay, Queensland. The figure to the right of the picture is engaged painting a shield. The curiously-shaped huts of the North Australian blacks form characteristic objects in the engraving. The engraving on page 166 of a corroboree in the far north is from a photograph by Mr. P. Foelsche, at Port Essington. The males group themselves as shown in our illustration, and stamp the ground with both feet simultaneously, making a peculiar sound, and keeping tune with a guttural exclamation. The first who sounds a false note or misses a beat leaves the group amidst the ridicule of the bystanders, and this process is continued until the number of performers is reduced to a pair, who divide the honours. These northern tribes are guilty of revolting acts of cannibalism. [Illustration: A NATIVE ENCAMPMENT IN QUEENSLAND.]
