One month after Latour's visit to Gallegos, Latour formally suspends him and replaces him with Vaillant. Vaillant immediately changes the tone of the parish from revelry to devotion, which is initially received with hostility by the Albuquerque Catholics. By Christmas, however, the parishioners join in Vaillant's religious zeal.
Latour sends Vaillant to Las Vegas on urgent business, but the younger priest does not return when he is expected. Latour is told several days after Vaillant's expected arrival that he has been taken ill while helping a village in the Pecos mountains handle an outbreak of black measles. Latour rides an army mule to the Pecos pueblo, where he enlists the aid of Jacinto. Jacinto and the other Indians convince Latour to stay overnight to avoid heavy winds. Against his wishes to help his friend immediately, Latour agrees to spend the night at the pueblo.
The respite offers Latour the opportunity to question his judgment on bringing the sickly and frail Vaillant to the Southwest. The reader is told that Vaillant had been prone to illness since childhood. When the two young men were seminarians, Vaillant had been sent every year to recuperate in the Volvic mountains. When the two men were in Ohio, Vaillant had taken ill with cholera twice. Latour hopes that his friend can once again cheat death.
