Gen. Porñrio Díaz, tile revolutionary leader who lias seized Matamoras and appears to be making stlch lieadway against the Mexican Government, is well known in the political and military history of tliat republio. He was regarded as the hero agiúnst the empire, iad it j was he who besieged and eaptured the city of Mexico f rom the Austrians, j gians and Mexican adherents of i milian, who held out af ter the f all of ' Queretaro. He was a candidate against i Juárez in 1867, and again in 1871. In the latter election he claimed to have ! received a plurality of votes, but gress decided against hún, and he pealed to arms and organized a serious j revolution. Juárez died in 1873, and Lsrdo, then Chief-justice oi the Supreme court, succeedodhimas President ad interim. A general amnesty was issued, and Diaz laid down his arms. In the regular election for Piesident which followed, Lerdo was elected without opposition, Diaz declining to become a candidate against hiin. But the adtninistration of Lerdo has not been popular, and for some time it has been evident that a revolution was inevitable. The first intimation carne from the State of M ichoacan, but tliey were not of a character to excite alarm. Tvvo or thre raonths since, however, a programme was proclaimed from the town of Trextepec, in Oaxaca, which declarad in vor of the Constitution of 1857, repudiated the present Govornment entirely, and pronounced in favor of Diaz as " General-in-chief of the regenerating armies." The plan was approved by the I mountain towns, a forcé was gathered, and the capital of the State eaptured. From that day to this, though suffering defeat now and then at the hands of the Government traops, the revolutionists have been gaining strength.
