Agricultural censuses have been taken repeatedly. For 1888 F. Latzina, L'agriculture et le bétail dans la République argentine (Paris, 1889). For 1895 (Secundo censo, see Population) the results are given in C. P. Salas, Bureau central de Statistique de la province de Buenos Aires and L'agriculture, l'élevage, et le commerce dans la province en 1895 (La Plata, 1897; maps by Delachaux). For 1908, Censo agro-pecuario nacional. La ganaderia y la agricultura en 1908 (Buenos Aires, 3 vols. quarto, 1909). Vol. iii contains a series of monographs dealing not only with the Pampean region, but the economic history of the whole country.
For 1914 (Tercer censo, see Population) the publication of vol. v, relating to agriculture, is unfortunately delayed. There is also available a census of cattle made in 1915 for the Buenos Aires province, Provincia de Buenos Aires, Min. Obras Publicas, Censo Ganadero (1916).
10. The Railways.
For the history of the railways see Rebuelto, "Historia del desarollo de los ferrocarriles argentinas" (Bol. Obras Publicas, vol. v, 1911, pp. 113-172, vol. vi, 1913, pp. 1-48 and 81-110, and vol. viii, 1913, pp. 1-32), and the entire series of the Boletin de Obras Publicas.
A sort of annual of the Argentine railways has been published every year since 1906 under the title Killik's Argentine Railway Manual (London, 1 vol. with map, last issue 1918).
11. The Paraná.
E. A. S. Delachaux, "Los problemas geograficos del territorio Argentino" (Rev. Univ. Buenos Aires, 1906, v), includes a study of the floods of the Paraná.
The chief source is the memoir of Repossini, "Memoria sobre el rio Paraná" (Bol. Obras Publicas, vol. vi, 1912, pp. 141-168 and 254-264, vol. vii, 1912, pp. 31-48 and 163-186, and vol. viii, 1913, pp. 33-99). It contains on a reduced scale the map issued by the Ministry of Public Works, which is not available in France. The defect is supplied by the English Admiralty Charts, "Rio de la Plata," 1869 (No. 2544 in the Catalogue of Admiralty Charts), and "River Paraná," parts i, ii, iii, iv, v, and vi of 1905 (Nos. 1982/A and 1982/B).
There is an interesting economic summary in W. S. Barclay, "The River Paraná, an economic survey" (Geogr. Journal, xxxiii, 1909, pp. 1-10).
