ton) to Berlin. Leverrier wrote to Doctor Galle, head of the observatory at Berlin, saying to him, clearly and decidedly, that the new planet was now in or close to such and such a position, and that if he would point his telescope to that part of the heavens he would see it; and moreover that he would be able to tell it from a star by its having a sensible magnitude, or disk, instead of being a mere point.

Galle got the letter on September 23, 1846. That same evening he pointed his telescope to the place Leverrier told him, and saw the planet. He recognized it first by its appearance. To his practised eye it did seem to have a small disk, and not quite the same aspect as an ordinary star. He then consulted Bremiker's great star-chart, the part just engraved and finished, and, sure enough, no such star was there. Undoubtedly it was the planet.

The news flashed over Europe at the maximum speed with which news could travel at that date (which was not very fast); and by October 1st Professor Challis and Mr. Adams heard it at Cambridge, and realized that in so far as there was competition in such a matter England was out of the race.

It was an unconscious race to all concerned, however. The French scientists knew nothing of the search in England. Adams's papers had never been published; and very annoyed the French were when a claim was set up in his behalf to a share in this magnificent discovery. As for Adams himself, we are told that by no word did he show resentment at the loss of the practical consummation of his discovery. His part in any controversy that arose was calm and dignified; but for a time his friends fought a public battle for his fame. It so happened that the public took a keener interest than it usually takes in scientific predictions; but the discussion has now settled down. All the world honors the bright genius and mathematical skill of John Couch Adams, and recognizes that he first solved the problem by calculation. All the world, too, perceives clearly the no less eminent mathematical talents of M. Leverrier, but it recognizes in him something more than the mere mathematician-the man of energy, decision, and character.

THE ACQUISITION OF CALIFORNIA

A.D. 1846

HENRY B. DAWSON

In the history of the United States, the acquisition of California carrying with it that of New Mexico, was a peculiar and unusual event, and one of immense significance in the expansion and development of the Republic. Together with the annexation of Texas, it was the most important result of the Mexican War. The California country, formerly an indeterminate territory of vast extent, was settled by Spanish missionaries in the seventeenth century. Their settlements within the present limits of the State of California date from the first foundation of San Diego in 1769. In 1822 the entire region called California became a part of the Mexican Republic, and it remained a possession of Mexico until the time of the transfer described below.

At the beginning of 1846 the population of California included, with about two hundred thousand Indians, six thousand Mexicans and perhaps two hundred Americans. War against Mexico had been declared in May, 1845, and already General Taylor had won the battles of Palo Alto and Resaca de la Palma, and had compelled the surrender of Monterey. While these operations were leading the United States forces to the rapid accomplishment of their work in Mexico proper, other movements were undertaken, the execution and outcome of which form the subject of Mr. Dawson's narrative. In 1848 California and New Mexico were ceded to the United States.

IMMEDIATELY after the opening of hostilities in the valley

of the Rio Grande (March, 1846), among the expeditions which were organized by the Federal authorities was one to move against and take possession of California and New Mexico, two provinces in the northern part of the enemy's country. The command of this expedition had been vested in General Stephen W. Kearney, and the force under his command had rendezvoused at Fort Leavenworth; and the most energetic measures had been adopted to insure its early departure and its ultimate

success.

Having completed all the arrangements, on June 26th the main body of this expedition had moved from the fort; and after a rapid but interesting march of eight hundred seventy

three miles, on August 18th it entered and took possession of Santa Fé, the capital of New Mexico, the Mexican forces, numbering four thousand, which had been collected to defend the town, having dispersed, without offering the least opposition, as it approached.

While these operations in New Mexico and on the western frontier of the United States were taking place, Brevet-Captain John C. Frémont, who had been engaged in explorations on the western slope of the Rocky Mountains, had also revolutionized the Province of California, and, to some extent at least, had anticipated the movements of the expedition commanded by General Kearney. The character of his mission being scientific and peaceful rather than warlike, he had not had an officer or soldier of the regular army in his company; and his whole force had consisted of sixty-two men employed by himself for security against the Indians and for procuring subsistence in the wilderness and desert country through which he had passed. For the purpose of obtaining game for his men and grass for his horses, in an uninhabited part of California, he had, during the winter of 18451846, solicited and obtained permission from the Mexican authorities to winter in the Valley of San Joaquin; but he had scarcely established himself before he received advices that the Mexican commander was preparing to attack him under the pretext that under the cover of a scientific mission he was exciting the American settlers in that vicinity to revolt.

In view of this threatened attack, and for the purpose of repelling it, Lieutenant Frémont immediately occupied a mountain which overlooked Monterey-although it was thirty miles from that city-and having intrenched it and raised the flag of the United States he waited the approach of the enemy. After remaining there until March 10, 1846, he retired to the northward, intending to march, by way of Oregon, to the United States; but about the middle of May, after he had quietly passed into Oregon, he had received information through Samuel Neal and Levi Sigler, two hunters who had been sent after him from Lassen's rancho, that the Mexican Governor of California was pursuing him, while the Indians, by whom he was surrounded, instigated by the enemy, had shown signs of hostility, and had killed or wounded five of his men.

Under these circumstances, on June 6, 1846, Lieutenant Frémont had resolved to turn on his pursuers with the little party under his command, and to seek safety, not merely in the overthrow of his pursuers, but in that of the entire Government of Mexico in the Province of California. Accordingly, on June 11th, Lieutenant Frémont, assisted by Captain Merritt and fourteen of the settlers, had attacked and captured an escort of horses destined for General Castro's troops-Lieutenant Arce, fourteen men, and two hundred horses remaining in his hands as the trophies of his victory. On the 15th the military post of Sonoma was surprised, and General Vallejo, Captain Vallejo, Colonel Greuxdon and several other officers, nine pieces of brass cannon, two hundred fifty stands of muskets, and other stores and arms were taken; and on the 25th the military commandant of the Province, who had moved toward the post with a heavy force to retake it, was attacked by Lieutenant Frémont and twenty men, and completely routed. Having thus cleared that part of the Province north of the Bay of San Francisco of the enemy, it is said that on July 5th Captain Frémont had assembled the American settlers at Sonoma, addressed them upon the dangers of their situation, and recommended a declaration of independence and war on Mexico as the only remedy; and that the hardy frontiersmen promptly accepted the proposal and raised the flag of independent California-a bear and a star on a red ground.

While these revolutionary movements were destroying the power of Mexico in the interior of the Province of California, and the expedition under General Kearney-ignorant of the fact that the work had been done already-was approaching its eastern borders for the same purpose, the naval force of the United States in the Pacific, under Commodore Sloat, had been assisting in the work of conquest. Having heard of the opening of hostilities on the Rio Grande, the Commodore-then at Mazatlan-hastened with the Savannah to Monterey in California, where he arrived on July 2d, and on the 7th he took possession of the town without opposition; the custom-house was seized, the American flag raised, and California declared to be "henceforward a part of the United States."

Within a few days intelligence of the action of Commodore

Sloat was received by the revolutionary leaders at Sonoma; and a battalion of mounted riflemen which had been organized among them was immediately moved to Monterey, the flag of the United States was substituted for the "bear and star," and the authority of the Commodore was immediately recognized. This battalion of mounted riflemen on its arrival at Monterey, July 23, 1846, was mustered into the service of the United States by Commodore Stockton, who had succeeded Commodore Sloat in command of the squadron-Captain Frémont being appointed its commandant, and Lieutenant A. H. Gillespie, of the Marines, its second officer-and it was immediately despatched on the sloop-ofwar Cyane to San Diego for the purpose of cutting off the retreat of General Castro, of the Mexican service, who had encamped and fortified his position near Ciudad de los Angeles, while the Commodore with his sailors-who landed from the Congress at San Pedro-moved against him in front. The expedition was eminently successful, as the Mexicans on the approach of the Commodore immediately evacuated their camp and fled in the greatest confusion-although most of the principal officers were subsequently captured-and, on August 13th, the Ciudad de los Angeles was occupied, again without opposition, by the American troops and seamen, and the conquest of California was apparently completed.

A short time afterward Commodore Stockton appointed Captain Frémont Governor of the Territory into which, by the proclamation of Commodore Sloat, the Province had been transformed; while Captain Gillespie was left, with nineteen men, in possession of Los Angeles; Lieutenant Talbot, of the Topographical Engineers, with nine men, was left at Santa Barbara; and, with his squadron, Commodore Stockton proceeded to San Francisco; while Governor Frémont, on September 8th, also moved to Monterey.

The main body had no sooner left Los Angeles than the Californians-who before the departure of the Commodore and the Governor had held secret meetings for the purpose-rose in arms for the expulsion of the invaders of their country. Indeed an attempt appears to have been intended before the Governor left the city; but, by timely precautions, it had been prevented; although the purpose and determination still continued and were
