“The walls are adobe, and the roofs of well-made tile.  It was built about sixty years since by the Indians of the country, under the guidance of a zealous priest.  At that time the Indians were very numerous, and under the absolute sway of the missionaries.  These missionaries at one time bid fair to christianize the Indians of California.  Under grants from the Mexican government, they collected them into missions, built immense houses, and began successfully to till the soil by the hands of the Indians for the benefit of the Indians.

“The habits of the priests, and the avarice of the military rulers of the territory, however, soon converted these missions into instruments of oppression and slavery of the Indian race.

“The revolution of 1836 saw the downfall of the priests, and most of these missions passed by fraud into the hands of private individuals, and with them the Indians were transferred as serfs of the land.

“This race, which, in our country, has never been reduced to slavery, is in that degraded condition throughout California, and does the only labour performed in the country.  Nothing can exceed their present degradation.”

The general closing remarks of Lieutenant Emory are as follow: 

“The region extending from the head of the Gulf of California to the parallel of the Pueblo, or Ciudad de los Angeles, is the only portion not heretofore covered by my own notes and journal, or by the notes and journals of other scientific expeditions fitted out by the United States.  The journals and published accounts of these several expeditions combined will give definite ideas of all those portions of California susceptible of cultivation or settlement.  From this remark is to be excepted the vast basin watered by the Colorado, and the country lying between that river and the range of Cordilleras, represented as running east of the Tulare lakes, and south of the parallel of 36 deg., and the country between the Colorado and Gila rivers.

“Of these regions nothing is known except from the reports of trappers, and the speculations of geologists.  As far as these accounts go, all concur in representing it as a waste of sand and rock, unadorned with vegetation, poorly watered, and unfit, it is believed, for any of the useful purposes of life.  A glance at the map will show what an immense area is embraced in these boundaries; and, notwithstanding the oral accounts in regard to it, it is difficult to bring the mind to the belief in the existence of such a sea of waste and desert; when every other grand division of the earth presents some prominent feature in the economy of nature, administering to the wants of man.  Possibly this unexplored region may be filled with valuable minerals.

“Where irrigation can be had in this country, the produce of the soil is abundant beyond description.  All the grains and fruits of the temperate zones, and many of those of the tropical, flourish luxuriantly.  Descending from the heights of San Barnardo to the Pacific one meets every degree of temperature.  Near the coast, the winds prevailing from the south-west in winter, and from the north-west in summer, produce a great uniformity of temperature, and the climate is perhaps unsurpassed in salubrity.  With the exception of a very few cases of ague and fever of a mild type, sickness is unknown.
