 His "Informe" or Report of 1702, published in Mexico City, was an influential early account of the peninsular missions, although its optimism about the potential of Baja California was something of an embarrassment to later Jesuit apologists.He conducted several exploratory trips seeking neophytes and future mission sites, including journeys to what would later be Mulegé, Mission La Purísima and Mission San Ignacio.His accounts of these travels contain additional ethnographic information on the Cochimí.
