THE CONDOR AND THE BULL.

There was a wooden cannon which was captured from the rebels in one of the northern provinces in the last revolution. It was made of slabs of wood bound together with hoops of iron, and appeared to have been used; it was a type of the earliest known cannon, and carried the thoughts of the spectators back to the days when artillery was first used on the battlefield. Horrible in appearance were embalmed heads from the country of the Tapajos; Dr. Bronson explained that this tribe used to preserve the heads of their enemies, and wear them on their necks as trophies of their valor. A string through the mouth was used for suspending such a prize; the eyes were filled with wax and cement, and the whole face was built out with this material, to make it as lifelike as possible. On the top of the head was a tuft of hair, and the positions of the ears were indicated by rosettes.

EMBALMED HEAD.

Close to these preserved heads was a case containing musical instruments resembling flutes and horns, and said to be of great antiquity; they were from the upper part of the Amazon Valley, and coeval with the incas of Peru. One trumpet attracted the attention of the youths; it was about three feet long, tapering regularly from end to end, and provided at the larger extremity with a fringe of feathers, which modulated the sound when the instrument was used. The attendant asked Frank and Fred to guess what it was made of; they named everything they could think of, but without success, and were finally told it was an alligator's tail!
