There has been much discussion regarding the location of the “pueblo” occupied by the Jumano that was dedicated to “the glorious Isidoro.” We may assume that it was not until after the visit of Salas to the Jumano on the plains in July–August, 1629, that this mission was founded, since the new friars did not arrive from Mexico until Easter of that year, and prior to that time no permanent missionaries were available even had the Jumano not been three hundred miles away on the prairies. We learn from the _Relacion_ of Fray Estevan Perea,[11] the successor of Benavides as custodian of the missions of New Mexico, and under whose guidance the new missionaries came in the spring of 1629, that there were sent to the pueblos of the Salinas—“in the great pueblo of the Xumanas, and in those called Pyros and Tompiras”—six priests and two lay religious, one of whom, Francisco de Letrado, is known to have been assigned to the Jumano alone. It does not seem necessary to look for the “great pueblo of the Xumanos” of which Benavides speaks, among the ruins of eastern New Mexico, from amongst the débris of which the massive walls of former Spanish churches and monasteries still rise, for it is scarcely likely that the Jumano occupied a village other than their own, or that the settlement was anything but an aggregation of dwellings of the more or less temporary kind which they were found to occupy when visited by Cabeza de Vaca and by Espejo on the lower Rio Grande.[12] That active missionary work was conducted by Letrado among the Jumano is certain. We have seen that this friar was assigned to the tribe soon after his arrival in New Mexico as a member of Perea’s band in the spring of 1629; but three years later we find him at Zuñi on his way to convert the savage and little-known “Cipias,” although he was murdered by the Zuñi before he reached them, on February 22, 1632—a century to the day before the birth of Washington. Why missionary work among the Jumano was thus apparently abandoned, there is no definite knowledge, but it would seem to have been due to another shifting of the tribe from New Mexico to the plains, and another change from their erstwhile sedentary life to that of buffalo hunters. There is a suggestion of this, indeed, in an account written by Fray Alonso de Posadas,[13] who states that Fray Juan de Salas and Fray Juan (Diego?) de Ortega, with an escort, visited the Jumano on a stream which they called Rio Nueces, and Ortega remained among them for six months. From this account the Rio Nueces might have been almost anywhere in the country of the plains, and not necessarily the present Rio Nueces of Texas.[14] The important point, however, is the fact that Letrado had abandoned his station among the Jumano in eastern New Mexico in 1632, and that in the same year Salas went forth again on the plains apparently for the purpose of bringing them back.
