An important confed- eracy or group of tribes apparently constituting a distinct stock, scattered in the forests along the Maraiion (Amazon), chiefly on the north or Ecuador side, about the confluence of the Pastaza and Santiago. They are a vigorous, wild, and warlike people, but at the same time honorable and faithful, and were never subjugat- ed by the Incas (see QnciirA). and only tem- porarily brouglit under the dominion of the Span- iards, whom they expelled in a general revolt in 1599. Their general appearance indicates muscu- lar strength and activity and quick intelligence. They live in well-built wooden houses, with plat- form beds instead of hammocks; cultivate corn, beans, and bananas, and weave cotton cloth. They use the blnwgim, bow. lance, and shield. and wear their hair long and flowing, with head- dresses of bright feathers. Their ordinary dress is a shirt without sleeves an<l a pair of short trousers; but in war they are stripped and paint-" ed. They are noted for preserving the dried heads of enemies slain in battle, and for the prac- tice of taking a strcmg emetic every morning as a preparation for the day's work. They have devclo])ed a system of signaling by means of large drums kept in every village, by which the ap- proach and strength of an enemy can be made known, or the warriors called to battle. JO.

JOACHIM, y.Va-Kem, JOSEPH (1831—). A distiiignishcil Hungarian violinist. He was born at Kittsee. near Pressburg, Hungary, of Jewish parents. His father was engaged in commercial pursuits, but discovered his son's musical (>- clivities, and at tb.e age of live years phucd him under Szervacziiisky, llie celebrated coiiccrtmcis- ter of Budapest. After two years' stud}' he made his first public appearance plajing duets with his master, after which he studied under Bohm at Vienna. In 1841 he was a pupil at the "ienna Conservatory studying counterpoint vuuler Hauptmann, and in 1843, wlu-n only twelve years of age. distinguished himself at a concert of Ma- dame 'iardot-(iarcia in Lci|)zig. In the spring of 1844 he visited England, where he was enthusi- astically received, returning to Leipzig in Novem- ber of the same year to play at one of the Cle- wandhaus concerts. Adopting the advice of his friends David and Jlendclssohn, he determined to continue his studies at Leipzig. He made visits to England at intervals until 1802, after whic li his appearance in London became an annual event. He was appointed concertmeister in 1849 of the orchestra at Weimar during the regime of Liszt, wl'.ose views were so diametrically opposed to his own ideals that a disagreement was in- evitable. He left Weimar in 1S,'54 to accept the post of concert conductor and solo violin- ist at the Court of Hanover, where he married Amalie Weiss, a well-known contralto singer. In 1S08 he was appointed liead of the Hochschule ftir ansiiliendc Toiikiin^t. His most important work is the Hungarian Concerto in D minor. His other compositions include overtures and inci- dental music to various plays; several marches and trios; ballads, and various forms of chamber music. His most .salient characteristics as a player are reflected in the general character of his written work, which is marked by sincerity, depth, and tenderness. It was as a quartet player, however, that his intellectual superiority over contemporary violinists was most marked; his quartet party consisting of himself, as first violin; De Ahna. second violin; Hausmann. 'cello, and Wirth. viola, have never been excelled. As a soloist he earned for himself the title of king of violinists. He is best known as the greatest master of style, repose, and tone of his day and generation. JOACHIM FREDERICK (1.546-1008).
