The gift nearest to Mr. Lick's heart was his great telescope, to be, as he said in his deed of trust, "superior to and more powerful than any telescope yet made, with all the machinery appertaining thereto, and appropriately connected therewith."

This telescope with its building was to be conveyed to the University of California, and to be known as the "Lick Astronomical Department of the University of California."

Various sites were suggested for the great telescope. A gentleman relates the following story: "One of the sites suggested was a mountain north of San Francisco. Mr. Lick was ill, but determined upon visiting this mountain; so he was taken on a cot to the station; and on arriving at the town nearest the mountain, the cot was removed to a wagon, and they started towards the summit. By some accident the rear of the wagon gave way, and the cot containing the old gentleman slid out on the mountain-side. This so angered him that he said he would never place the telescope on a mountain that treated him in that way, and ordered the party to turn back towards San Francisco."

During the summer of 1875 Mr. Lick sent Mr. Fraser, his trusted agent, to report on Mount St. Helena, Monte Diablo, Mount Hamilton, and others. In many respects the latter, in sight of his old mill at San José, seemed the best situated of all the mountain peaks. "Yet the possibility that a complete astronomical establishment might one day be planted on its summit seemed more like a fairy-tale than like sober fact," says Professor Edward S. Holden, Director of the Lick Observatory. "It was at that time a wilderness. A few cattle-ranches occupied the valleys around it. Its slopes were covered with chaparral or thickets of scrub oak. Not even a trail led over it. The nearest house was eleven miles away." It was and is the home of many rattlesnakes. They live upon squirrels, and small birds and their eggs, and come up to the top of the mountain in quest of water.

Sir Edwin Arnold, who visited Mount Hamilton, tells this incident of the "road-runner," the bird sometimes called "chaparral cock," as it was told to him. "The rattlesnake is the deadly enemy of its species, always hunting about in the thickets for eggs and young birds, since the 'road-runner' builds its nest on the ground. When, therefore, the 'chaparral cocks' find a 'rattler' basking in the sun, they gather, I was assured, leaves of the prickly cactus, and lay them in a circle all around the serpent, which cannot draw its belly over the sharp needles of these leaves. Thus imprisoned, the reptile is set upon by the birds, and pecked or spurred to death."

Mount Hamilton, fifty miles southeast of San Francisco, is near San José, twenty-six miles eastward, and thus easy of access, save the difficulty of reaching its summit, 4,300 feet above the sea. This was overcome by the willingness of Santa Clara County to construct a road to its top; which road was completed in December, 1876, at a cost of about $78,000. The road rises 4,000 feet in twenty-two miles; and the grade nowhere exceeds six and one-half feet in one hundred, or 343 feet to the mile. Towards the top it winds round and round the flanks of the mountain itself.

The view from the top of the mountain is most inspiring. "The lovely valley of Santa Clara and the Santa Cruz mountains to the west, a bit of the Pacific and the Bay of Monterey to the southwest, the Sierra Nevada (13,000-14,000 feet) with countless ranges between to the southeast, the San Joaquin valley with the Sierras beyond to the east, while to the north lie many lower ranges of hills, and on the horizon Mount Shasta, or Lassens' Butte (14,400 feet), 175 miles away. The Bay of San Francisco lies flat before you, and beyond it is Mount Tamalpais at the entrance to the Golden Gate."

"One of the gorges in the vicinity of Mount Hamilton," writes Taliesin Evans in the May, 1886, Century, "is reputed to have been a favorite retreat of Joaquin Murietta, the famous bandit, whose name was a terror to the early settlers of the State. A spring, situated a mile and a half east of Observatory Peak, at which he is said to have drawn water, now bears the name of 'Joaquin's Spring.'"

On June 7, 1876, Congress gave the land for the site, 1,350 acres; and other land was given and purchased, till the Observatory now has 2,581 acres. It was necessary to remove 72,000 tons of solid rock from the mountain summit, which was lowered as much as thirty-two feet in places, that the buildings might have a level foundation. Clay for making the brick was found about two and one-half miles below the Observatory (by the road), thus saving over $46,000 in the 2,600,000 bricks used. Springs also were fortunately discovered about 340 feet below the present level of the summit.

In 1879, after the site had been decided upon, Professor S. W. Burnham of Chicago was asked by the Lick trustees to test it for astronomical purposes. He took his telescope, and remained there during August, September, and October. Out of sixty nights he found forty-two were of the very highest class for making observations, while eleven were foggy or cloudy. He discovered forty-two new double stars while on the top of the mountain.
