who had been detached with a party of cavalry, brought word that Canterac was advancing from Jauja with all his army.
To the south of Pasco, at the head-waters of the Rio Grande, commences the great lake of Reyes, which lies between the two ranges of the Cordillera, and occupies all the low ground as far as the entrance of the valley of Jauja. On its eastern bank there runs a level road, on the western bank is another which leads to Junin, and is much rougher.
