Although no herding is necessary, about 200 or more trained goats are kept on the island continually, which to all intents and purposes take the place of the shepherd dogs so necessary in mountainous districts where sheep are raised. Whenever the animals are removed from one quarter to another, the man in charge takes out with him several of the goats, exclaims in Spanish, "Cheva" (meaning sheep). The goat, through its training, understands what is wanted, and immediately runs to the band, and the sheep accept it as their leader, following wherever it goes. The goat, in turn, follows the man to whatever point he wishes to take the band. To prevent the sheep from contracting disease, it is necessary to give them a washing twice a year. Moore, having so many on hand, found it necessary to invent some way to accomplish this whereby not so much expense would be incurred and time wasted. After experimenting for some time, he had a ditch dug 8 feet in depth, a little over 1 foot in width, and 100 feet long. In this he put 600 gallons of water, 200 pounds of sulphur, 100 pounds of lime, and 6 pounds of soda, all of which is heated to 138°. The goats lead the sheep into a corral or trap at one end, and the animals are compelled to swim through to the further end, thus securing a bath and taking their medicine at one and the same time. The owner of the island and sheep, A.P. Moore, a few years ago purchased the property from the widow of his deceased brother Henry, for $600,000. Owing to ill health, he has rented it to his brother Lawrence for $140,000 a year, and soon starts for Boston, where he will settle down for the rest of his life. He still retains an interest in the Santa Cruz Island ranch, which is about 25 miles southeast of Santa Barbara. This island contains about 64,000 acres, and on it are 25,000 sheep. On Catalina Island, 60 miles east of Santa Barbara, are 15,000 sheep, and on Clementa Island, 80 miles east of that city, are 10,000 sheep. Forty miles west of the same city is San Miguel, on which are 2,000 sheep. Each one of these ranches has a sailing vessel to carry freight, etc., to and fro between the islands and the mainland, and they are kept busy the greater part of the time.--_San Francisco Call_. * * * * * THE DISINFECTION OF THE ATMOSPHERE. At the Parkes Museum of Hygiene, London, Dr. Robert J. Lee recently delivered a lecture on the above subject, illustrated by experiments.
