  1. A Ferraria da Foz de Alge.
    J. Silva Carvalho (68 páginas)
    Resumo: This article is a contribution to the history of the iron industry in Portugal and it deals with the activity of the iron factory of Foz de Alge from 1802 to 1819. The iron factory is at the Alge river, a few kilometers away from Figueiró dos Vinhos, and some iron based on the ores extracted in that region was then obtained. The iron factory was closed during several years but with the arrival at Portugal of José Bonifácio de Andrade e Silva, after a trip of years through the main iron factories abroad, made the Government try to reopen it again. Andrade e Silva, anxious to show his usefulness, after been appointed Intendant of Mines and Metals of the Kingdom, has the ruins of Foz de Alge rebuilt and contracted foreign staff, practically all German, to start the industry.
    The Government did not encourage this initiative as it ought to. The State establishments very rarely used iron, and when they did it, they did not pay for it. The sales profit was not sufficient to cover the workers salaries, and the debts were paid with the money came from a coal mine in Oporto.
    In this article there are some references to the misfortunes caused by the French Invasions and chronological news are given of the various attempts to improve the iron production. The article also refers to the plots between that Intendency and the Royal Factory od Silks, which hurt greatly the feelings of José Bonifácio de Andrade e Silva, and contributed imensely towards his decision to go to Brazil where he became the head of the party which gave independence to that country.
  2. Estudo de Algumas Formações Calcárias dos Distritos de Vila Real, Viseu e Guarda.
    A. C. de Medeiros ; F. Limpo de Faria (16 páginas)
    resumo: In this work the autors present a study about the limestones of the Vila Real district and also state some outcrops related with these, of the Viseu a Guarda districts. The referred limestones are interstratified in the anti-silurian formations atributed to the inferior Cambrian (Cb1) in the geological map of Portugal of 1899, in layers nearly always alternate with schists, thus originating lenticular masses more or less large. A lateral passage from limestone to schists can practically always be noticed. In each outcrop, the limestones have, usually, very similar petrographic mineralogic and chemical characteristics.
    The microscopic observation showed: predominating calcite; acessorily, quartz, moscovite, pyrite and ferriferous pigments. In the attached table the results of carried out chemical analysis are shown. As regards the economical point of view, the limestones have only local interest, either in the manufacture of lime or in agriculture for the correction of soils.
