municated to it by the tides, or by the "pull" of the sun and moon, it has been found almost impossible as yet to carry out the object, so greatly are these movements obscured by the ceaseless and inexplicable vibrations of the solid earth. There is nothing unreasonable in the supposition that, if an instrument can be constructed to show these, the ears of animals and birds—living organisms, and not iron and steel—should be able to discover the tremors of the surface. The wild hunter can still further check or altogether prevent observation by moving on hands and knees, when his weight is widely distributed. In the particular instance of a fish he endeavours to come to the margin of the water at the rear of the fish, whose eyes are so placed that it can see best in front. When he has arrived at the margin, and has to rear himself up, if from hands and knees, or, if already upright, when he commences his work, he tries to conceal his arms, or, rather, to minimize their peculiar appearance as much as practicable by keeping them close to his sides. All this time I am supposing that you are looking at the poacher from the fish. To a fish or any wild animal the arms of a man are suspicious. No other creature that they know possesses these singular appurtenances, which move in almost any direction, and yet have nothing to do with locomotion. You may be sure that this great difference in the anatomical construction of a man is recognized by all wild animals once they are compelled for their own safety to observe him. Arms are so entirely opposite to all the varieties of limb possessed by the varieties of living creatures.
