_Historical._--Although the trail was blazed by Davidson, it is Wagner who first claims our attention. He has concluded, after an exhaustive study of all available evidence, that Drake anchored first in Trinidad Bay and later in Bodega Bay. The harbor now called Drake's Bay was not, according to Wagner, the site of Drake's landfall in 1579. Robertson, next mentioned above, is the author of a critical review of previous "arguments advanced by certain historians in their selection of 'The Harbor of St. Francis.'" _Anthropological._--Wagner's major work on Drake bears abundant evidence that this historian, at least, is cognizant of the value of the ethnographic check method. However, he has not utilized all available documentary or ethnographic data to the fullest extent--a procedure of the utmost importance. Davidson used the ethnographic method of solving the problem when he identified the Limantour Estero shellmound site with the Indian village depicted on the border map _Portus Novae Albionis_ of the Jodocus Hondius map _Vera totius expeditionis nauticae_ (Amsterdam, 1590?)[11] and cited as evidence a tradition of the Nicasio Indians. In his day, many Coast Miwok Indians from Drake's Bay and Bodega Bay must have been still living. If at that time he had obtained from them the information which can no longer be found, owing to the extinction of the tribe, he would have performed an inestimable service. In 1908, S. A. Barrett published his important work on Pomo ethnogeography in which he reproduced the California data on the voyage of Drake and made a brief evaluation.[12] After attempting a linguistic check with the word _Hioh_ and directing attention to the feather-decorated baskets as Pomo-like, Barrett concludes that "these facts therefore point further to the tenability of the belief that Drake's landing was somewhere north of San Francisco bay, possibly even north of Point Reyes, though Pomo of the Southern and Southwestern dialectic area may have journeyed down to Drake's bay bringing their boat-shaped and ornamented baskets...."[13] In Professor Kroeber's _Handbook of the Indians of California_ there is an ethnographical analysis of a paraphrased version of _The World Encompassed_, together with an inquiry (more searching than that of Barrett's in 1908) into the identification of the words, such as _Hioh_, _Patah_, _Tobah_, and _Gnaah_, which appear in the Fletcher account.[14] Kroeber summarizes: "The ethnologist thus can only conclude that Drake summered on some piece of the coast not many miles north of San Francisco, and probably in the lagoon to which his name now attaches. He is assured that the recent native culture in this stretch existed in substantially the same form more than 300 years ago, and he has tolerable reason to believe that the Indians with whom the great explorer mingled were direct ancestors of the Coast Miwok."[15]
