He loved animals, especially the horse, and had the largest horse farm for raising horses in the world. Some of his remarkable thoroughbreds and trotters were Electioneer, Arion, Palo Alto, Sunol, "the flying filly," Racine, Piedmont that cost $30,000, and many others. He spent $40,000, it is said, in experiments in instantaneous photography of the horse; and a book resulted, "The Horse in Motion," which showed that the ideas of painters about a horse at high speed were usually wrong. No one was ever allowed to kick or whip a horse or destroy a bird on the estate. Mr. George T. Angell of Boston tells of the remark made to General Francis A. Walker by Mr. Stanford. The horses of the latter were so gentle that they would put their noses on his shoulder, or come up to visitors to be petted. "How do you contrive to have your horses so gentle?" asked General Walker. "I never allow a man to _speak_ unkindly to one of my horses; and if a man _swears_ at one of them, I discharge him," was the reply. There were large greenhouses and vegetable gardens at Palo Alto, and acres of wheat, rye, oats, and barley. But the most interesting and beautiful and highly prized of all the charms at Palo Alto was an only child, a lad named Leland Stanford, Jr. He was never a rugged boy; but his sunny, generous nature and intellectual qualities gave great promise of future usefulness. Mrs. Sallie Joy White, in the January, 1892, _Wide Awake_, tells some interesting things about him. She says, "His chosen playmate was a little lame boy, the son of people in moderate circumstances, who lived near the Stanfords in San Francisco. The two were together almost constantly, and each was at home in the other's house. He was very considerate of his little playfellow, and constituted himself his protector." When Mrs. Sarah B. Cooper was making efforts to raise money for the free kindergarten work in San Francisco suggested by Felix Adler in 1878, she called on Mrs. Stanford, and the boy Leland heard the story of the needs of poor children. Putting his hand in his mother's, he said, "Mamma, we must help those children." "Well, Leland," said his mother, "what do you wish me to do?" "Give Mrs. Cooper $500 now, and let her start a school, then come to us for more." And Leland's wish was gratified. "Between this time, 1879, and 1892," says Miss M. V. Lewis in the _Home Maker_ for January, 1892, "Mrs. Leland Stanford has given $160,000, including a permanent endowment fund of $100,000 for the San Francisco kindergartens." She supports seven or more, five in San Francisco, and two at Palo Alto.
