They are not mentioned in the Diligencias of August, 1756, but Barrios wrote of their being there in January, 1757 (Letter to the viceroy, June 12, 1757). From his statement it is inferred that January was the month of their arrival, although this is not certain. See the statement that the viceroy was sending letters by the missionaries, Jan. 19, 1757. These might be new missionaries. (Historia 91, expediente 2.)
