Even before the huge spoil is cut up, four musk-glands, placed by twos under its jaw, and on its belly, near the beginning of the tail, must be carefully taken out, to prevent the diffusion, over the whole body, of the penetrating odor of the greasy, brown liquid they contain. These glands, which are about an inch and a half long and as thick as a finger, are carefully tied up and suspended in the sun to dry. Mixed with a little rose-water, their contents serve, as we were told, to perfume the raven-black tresses of the elegant Bolivian ladies at Santa Cruz de la Sierra and Cochabamba, in spite of, or rather by reason of, their strong scent, which gives the headache to all save these strong-nerved senoritas, who love a bull-fight above everything, who know how to roll the cigarrito, and to dance the fandango with matchless grace, but who scarcely are able to write their own names. After such a pleasant interlude of fishing or hunting, the paddles are plied with renewed vigor until the evening, when sleeping quarters are selected, either on a sand-bank or in the forest. The canoes are moored by strong piassaba ropes in some recess of the bank, where they are protected against drifting trunks; the tents are erected, and preparations ensue for the principal meal. Meanwhile, after the very short interval of twilight usual in the tropics, night almost suddenly throws her dark veil over the valley, and the bright constellations of the southern sky in quiet majesty adorn the firmament.
