 in the district in question, accompanied by a pecuniary indemnity, was signed by President Alves at Petropolis on the 17th of November 1903. During the remainder of the term of this president internal and financial progress were undisturbed save by an outbreak in 1904 in the Cunani district, the very portion of disputed territory which had been assigned to Brazil by the arbitration with France. This province, being difficult of access, was able for a time to assert a practical independence. In 1906 Dr Affonso Penna, three times minister under Pedro II., and at that time governor of the state of Minas-Geraes, of which he had founded the new capital, Bello Horizonte, was elected president, a choice due to a coalition of the other states against São Paulo, to which all the recent presidents had belonged. Penna’s presidency was distinguished by his successful efforts to place the finances on a sound basis. He died in office on the 14th of June 1909. (K. J.; C. E. A.; G. E.)&emsp;

 BRAZIL, a city and the county-seat of Clay county, Indiana, U.S.A., situated in the west central part of the state, about 16 m. E. of Terre Haute and about 57 m. W.S.W. of Indianapolis. Pop. (1890) 5905; (1900) 7786 (723 foreign-born); (1910) 9340. It is served by the Central Indiana, the Chicago & Eastern Illinois, the Evansville & Indianapolis and the Vandalia railways, and is connected with Indianapolis, Terre Haute and other cities by an interurban electric line. The principal business thoroughfare is part of the old National Road. Brazil’s chief industrial importance is due to its situation in the heart of the “Brazil block” coal (so named because it naturally breaks into almost perfect rectangular blocks) and clay and shale region; among its manufactures are mining machinery and tools, boilers, paving and enamelled building bricks, hollow bricks, tiles, conduits, sewer-pipe and pottery. The municipality owns and operates its water-works. The first settlement here was in 1844; and Brazil was incorporated as a town in 1866, and was chartered as a city in 1873.

 BRAZIL NUTS, the seeds of Bertholletia excelsa, a gigantic tree belonging to the natural order Lecythidaceae, which grows in the valleys of the Amazons and generally throughout tropical America. The tree attains an average height of 130 ft., having a smooth cylindrical trunk, with a diameter of 14 ft. 50 ft. from the ground, and branching at a height of about 100 ft. The lower portion of the trunk presents a buttressed aspect, owing to the upward extension of the roots in the form of thin prop-like walls surrounding the stem. The fruit of the tree is globular, with a diameter of 5 or 6 in., and consists of a thick hard woody shell, within which are closely packed the seeds which constitute the so-called nuts of commerce. The seeds are triangular in form, having a hard woody testa enclosing the “kernel”; and of these each fruit contains from eighteen to twenty-five. The fruits as they ripen fall from their lofty position, and they are at the proper season annually collected and broken open by the Indians. Brazil nuts are largely eaten; they also yield in the proportion of about 9 oz. to each ℔ of kernels a fine bland fluid oil, highly valued for use in cookery, and used by watchmakers and artists.

 BRAZIL WOOD, a dye wood of commercial importance, obtained from the West Indies and South America, belonging to the genera Caesalpinia and Peltophorum of the natural order Leguminosae. There are several woods of the kind, commercially distinguished as Brazil wood, Nicaragua or Peach wood, Pernambuco wood and Lima wood, each of which has a different commercial value, although the tinctorial principle they yield is similar. Commercial Brazil wood is imported for the use of dyers in billets of large size, and is a dense compact wood of a reddish brown colour, rather bright when freshly cut, but becoming dull on exposure. The colouring-matter of Brazil wood, brazilin, C16H14O5, crystallizes with 1 H2O, and is freely soluble in water; it is extracted for use by simple infusion or decoction of the coarsely-powdered wood. When freshly prepared the extract is of a yellowish tint; but by contact with the air, or the addition of an alkaline solution, it develops a brick-red colour. This is due to the formation of brazilein, C16H12O5·H2O, which is the colouring matter used by the dyer. Brazilin crystallizes in hexagonal amber yellow crystals, which are soluble in water and alcohol. The solution when free of oxygen is colourless, but on the access of air it assumes first a yellow and thereafter a reddish yellow colour. With soda-ley it takes a brilliant deep carmine tint, which colour may be discharged by heating in a closed vessel with zinc dust, in which condition, the solution is excessively sensitive to oxygen, the slightest exposure to air immediately giving a deep carmine. With tin mordants Brazil wood gives brilliant but fugitive steam reds in calico-printing; but on account of the loose nature of its dyes it is seldom used except as an adjunct to other colours. It is used to form lakes which are employed in tinting papers, staining paper-hangings, and for various other decorative purposes.

 BRAZING AND SOLDERING, in metal work, termed respectively hard and soft soldering, are processes which correspond with soldering done at high and at low temperatures. The first embraces jointing effected with soldering mixtures into which copper, brass, or silver largely enter, the second those in which lead and tin are the only, or the principal, constituents. Some metals, as aluminium and cast iron, are less easily soldered than others. Aluminium, owing to its high conductivity, removes the heat from the solder rapidly. Aluminium enters into the composition of most of the solders for these metals, and the “soldering bit” is of pure nickel.

The hard solders are the spelter and the silver solders. Soft spelter solder is composed of equal parts of copper and zinc, melted and granulated and passed through a sieve. As some of the zinc volatilizes the ultimate proportions are not quite equal. The proportion of zinc is increased if the solder is required to be softer or more fusible. A valuable property of the zinc is that its volatilization indicates the fusing of the solder. Silver solder is used for jewelry and other fine metal work, arid has the advantage of high fusing points. The hardest contains from 4 parts of silver to 1 of copper; the softest 2 of silver to 1 of
