So the spell of Spanish invincibility was broken at last. Spain was no longer mistress of the seas.

Next on her brilliant roll of navigators, comes Juan de Fuca, who (1592) discovered the straits that now bear his name. Spain still wanting a harbor in which the Manila galleons could refit when homeward bound, Sebastian Vizcaino (1602-1603), sometimes called "the Biscayner," entered the haven of San Diego, and that of Monterey,[9] which he then named, as he also did the one lying within Point Reyes, called by him Port San Francisco.[10] Exploration of this coast then ceased for a century and a half.

The real advance into California (1768), like all other Spanish movements on this continent, originated in a half-monkish, half-military plan for the conquest, conversion and civilization of the country. Enough was known of its soil and climate to show how far both exceeded the sterile steppes of New Mexico, where Spanish advance had already reached its farthest limit, and like a stream that meets an obstacle in its path, was turned into another channel. For where plants grow and rivers flow, God has fixed the abodes of men.

This movement began[11] from the missions of Lower California. It was designed to extend the system by which Spain had first conquered, and since ruled, Mexico into the unoccupied and little-known province of Alta, or Upper, California. The viceroy was to furnish soldiers, the president-prelate of the Franciscan order, missionaries.

Thus coast batteries and forts were to be built for the defence of the best harbors, as well as to sustain the missions themselves, so forming a line of military strength along the coast sufficient to repel assault by sea or land, while the mountains behind them would be a barrier between the missions and the wild tribes who lived in the great valleys beyond. One arm was to seize upon and firmly hold the country in its grasp, while the other should gradually bring it into subjection to the Catholic faith. Then, with clerical rule once established, civil order was to come in. Therefore the first essential thing was to build a fort, and the second a church. In this way it was proposed to make rallying-points for civilization of these missions,[12] although the plan founded an oligarchy and nothing else.

The Spaniards did not mean to till the soil themselves, but to make the Indians do it for them. Setting this scheme at work, a Franciscan mission was begun at San Diego in July, 1769. The next year another was established at Monterey. From these missions explorers presently made their way out to the valley of the San Joaquin, and even as far north as the great bay of San Francisco (1772), which took to itself, a little later, the name of the old Port San Francisco, with which it must not be confounded.
