paialled to the line from Mesa Grande to Pala. At Ramona are found abundant tine garnet (essonite), with topaz and beryl, notably the rose variety, but not much tourmaline, no kunzite, and, in general, little of the lithia minerals. Around Jacumba are found beryl and essonite garnet (often called hyacinth); the latter is abundant and at one or two points has been worked somewhat for several years. Jacumba, or Jacumba Hot Springs, is close to the Mexican line, some 20 miles east of Campo, and almost on the western edge of the Colorado desert.
NONCRYSTALLINE QUARTZ. ROSE CHALCEDONY.
A very beautiful pink chalcedony, occurring in rather a peculiar manner, has been found by Mr. W. B. Coombs, of Needles, San Bernardino County. He noticed pieces of pink and also of white chalcedony as float material in washes or gullies about 3£ miles west of Siberia station, a siding on the Santa Fe Railway. Following these up several gulches he traced them to outcroppings of small quartz veins in a granitic rock that had apparently been altered by sonfe volcanic action. The locality is near what is known as Ash Hill, and there are porphyritic rocks and old craters in the vicinity.
Among the interesting specimens of chalcedony found at various points along the Pacific coast of California and Oregon, one of the most remarkable is mentioned as having been found on Pebbly Beach, Crescent City. Del Norte County, Cal. This specimen was a geode ■ii inches in length and 3^ by 3i in the other dimensions and contained a teaspoonf ul of water with a moving bubble. It was reported by Mr. Frank Clovenow. of Pebbly Beach. These hollow geodes of chalcedony, containing water, which have been called natural sealed flasks and also hydrolites, have been long known from some of these Pacific beaches, and have been sought with much interest by collectors, but nothing approaching the size of this specimen has ever been found before.
The last reference to the chrysoprase occurrences in California in the reports of the writer to this Bureau was in the report for 1901. The following general summary is derived from recent data gathered in connection with a report to the State mining bureau of California. Chrysoprase was discovered in Tulare County in 1878 by Mr. George W. Smith, a surveyor, of Visalia. He presented specimens to Mr. M. Braverman, of that place, who identified them as chrysoprase from the presence of nickel oxide. Later the State mining bureau con-
