[626] When wars were waged in the immediate vicinity of Rome the augurs could easily accompany the commander; cf. Livy iv. 18. 6; Cic. Leg. ii. 8. 21. But they certainly did not often go as far as Samnium; cf. Livy viii. 23. 16; ix. 38. 14. Though the augurs remained at Rome, the auspices followed the commander into the field; Livy xxii. 1. 6; p. 105, n. 1.

[633] The elder Tiberius Gracchus vitiated the election of his successors in the consulship by forgetting to renew the auspices, when, after entering the city to preside over the senate, he recrossed the pomerium to hold the election in the Campus; Cic. N. D. ii. 4. 11; Div. i. 17. 33; cf. Tac. Ann. iii. 19.

The reason for the auspication on such occasions is differently stated by the authorities, but the interpretation given by Jordan-Hülsen, Top. d. Stadt Rom, 1. iii. 472 f., that this brook marked the boundary of the city auspices, seems preferable.
