This mission, located near the sea, and twelve leagues south of San Juan, was founded in 1798 by padre Peyri, who had devoted himself for years to the improvement of the Indians. The buildings occupy a large square, in the centre of which a fountain still plays; along the front runs a corridor, supported by thirty-two arches, ornamented with latticed railings; while the interior is divided into apartments suited to the domestic economy of a large establishment. Here the wool of the sheep which grazed on the hills around, was woven into blankets, and coarse apparel for the Indians, while the furrowed field waved for miles under the golden grain. The reeling grape, the blushing peach, the yellow orange, the mellow pear, and luscious melon filled the garden, and, loaded the wings of the zephyr with perfume. In 1826 it had three thousand Indians, 70,000 head of cattle, 2000 horses, 140 yoke of tame oxen, 300 mules, 68,000 sheep, and a tract of land, around half of which you could not gallop between sun and sun. Its massive stone church still remains, and the remnants of its greatness are now in the hands of an administrator who little heeds the object which animated its founder. MISSION OF SAN DIEGO. This mission, situated fourteen leagues south of San Luis Rey, and near the town that bears its name, was founded in 1769 by padre Junipero Lerra, and was the first established in Alta California. Its possessions covered the whole tract of land which circles for leagues around the beautiful bay upon which its green hills look. Here the first cattle were corralled, the first sheep sheared, the first field furrowed, the first vineyard planted, and the first church bell rung. The Indian heard in this strange sound the invoking voice of his God, and knelt reverently to the earth. The success of this mission paved the way for the establishment of others, till the whole coast was sprinkled with their churches, and every green glade filled with their wild converts and lowing herds. But the padres and their neophytes are gone, and all the memorials that remain are a cumbrous ruin. Gigantic skeletons of things that were! THE RAILROAD TO CALIFORNIA.
