GEOGRAPHIC DISTRIBUTION. The territory of the Costanoan family extends from the Golden Gate to a point near the southern end of Monterey Bay. On the south it is bounded from Monterey Bay to the mountains by the Esselenian territory. On the east side of the mountains it extends to the southern end of Salinas Valley. On the east it is bounded by a somewhat irregular line running from the southern end of Salinas Valley to Gilroy Hot Springs and the upper waters of Conestimba Creek, and, northward from the latter points by the San Joaquin River to its mouth. The northern boundary is formed by Suisun Bay, Carquinez Straits, San Pablo and San Francisco Bays, and the Golden Gate. _Population._--The surviving Indians of the once populous tribes of this family are now scattered over several counties and probably do not number, all told, over thirty individuals, as was ascertained by Mr. Henshaw in 1888. Most of these are to be found near the towns of Santa Cruz and Monterey. Only the older individuals speak the language. ESKIMAUAN FAMILY. > Eskimaux, Gallatin in Trans. and Coll. Am. Antiq.
