Padre Serra's diary, kept in his own handwriting during this trip from Loreto to San Diego, is now in the Edward E. Ayer Library in Chicago. Some of his expressions are most striking. In one place, speaking of Captain Rivera's going from Mission to Mission to take from them "whatever he might choose of what was in them for the founding of the new Missions," he says: "Thus he did; and altho it was with a somewhat heavy hand, it was undergone for God and the king."

The work of Galvez for Alta California was by no means yet accomplished. Another vessel, the "San José," built at his new shipyard, appeared two days before the "San Antonio" set sail, and soon afterwards Galvez went across the gulf in it to secure a load of fresh supplies. The sixteenth of June the "San José" sailed for San Diego as a relief boat to the "San Carlos" and "San Antonio," but evidently met with misfortune, for three months later it returned to the Loreto harbor with a broken mast and in general bad condition. It was unloaded and repaired at San Blas, and in the following June again started out, laden with supplies, but never reached its destination, disappearing forever without leaving a trace behind.
