sustain a mission settlement, the Fathers needed either Spanish colonists or converted natives to cultivate crops and tend livestock in the volume needed to support a fair-sized Church establishment. Scarcity of imported materials and lack of skilled laborers compelled the Fathers to employ simple building materials and methods. Although the Spanish hierarchy considered the missions temporary ventures, individual settlement development was not based simply on a priestly whim. The founding of a mission followed long-standing rules and procedures. The paperwork involved required months, sometimes years of correspondence, and demanded the attention of virtually every level of the Spanish bureaucracy. Once empowered to erect a mission in a given area, the men assigned to it chose a specific site that featured a good water supply, plenty of wood for fires and building material, and ample fields for grazing herds and raising crops. The Fathers blessed the site, and with the aid of their military escort fashioned temporary shelters out of tree limbs roofed with thatch, reeds, or in Pimería Alta saguaro ribs or ocotillo branches topped with brush and mud. These simple huts would ultimately give way to the stone and adobe buildings that exist today. The majority of structures, indeed whole villages, were oriented on a roughly east–west axis to take the best advantage of the sun's position for interior illumination; the exact alignment depended on the geographic features of the particular site. Directives from Spain clearly stated that villages were to be sited on the west side of any valley so that the sun would shine in the homes first thing in the morning, discouraging slothful behavior on the part of the inhabitants. When founding a mission compound, first the spot for the church itself was selected, its position marked and then the remainder of the mission complex would be laid out. Workshops, kitchens, living quarters, storerooms, and other ancillary chambers were usually grouped in a quadrangle, inside which religious celebrations and other festive events could take place. List of missions This listing of the sites founded by Kino is not complete. Also, since names have changed over time, there appears to be some duplication. They are: Nuestra Señora de Guadalupe located near present-day La Paz, Baja California, was founded in April 1683 and abandoned four months later. Kino wrote in his astronomical treatise on comets that he dedicated his missionary life to Our Lady of Guadalupe. Kino, as
