It argues that the search for Ice Age remains depends on close cooperation between excavators and representatives of anthropology and related sciences. Geological evidence is emphasized as essential for verifying discoveries, placing fossils or artifacts in proper time, and distinguishing reliable findings from rumor or spurious reports.

GLACIAL MAN\n\nA PLAN OF COOPERATION BETWEEN EXCAVATORS AND REPRE-SENTATIVES OF THE SCIENCES OF MAN AND OF THE EARTH  \nThe extension of human life backward through hundreds of thousandsof years has been widely demonstrated throughout the world.Fossil re-mains of man and articles of his primitive handiwork have been discoveredin most of the great continental areas.China Man(Sinanthropus pekinen-sis),recently found in a stone quarry near Peking,may have lain buried  \nFIGURE I.Pithecanthropus erectus,or Java Man.Restored by J.H.McGregor.Used by permission of the American Museum of Natural History.  \nover a million years,and so also may the famous fragments of Java Man(Pithecanthropus erectus),discovered by the Dutch surgeon Dubois nearlyforty years ago(Figure 1).  \nOnly in the Americas is the great antiquity of man still in doubt.Mostarchaeologists believe that the first families of America were migrants fromEastern Asia,who probably crossed from Siberia and gradually made their  \nway down the coast and across the land.But there is still a question whetherthe first American migrations occurred before the Ice Ages(approximatelythe Pleistocene,as the geologist reckons time),during the successive glacia-tions that swept down in enormous ice sheets from Northwest Canada andfrom Labrador,or well after the last ice sheet had melted and delivered itsroaring waters to such great river channels as the Mississippi system,theConnecticut,and the Susquehanna.  \nOur abundant Indian cultures,as we now know them,belong to a muchlater period.Here we reckon time in centuries,or at most in single millen-niums.What lies behind in human history?The entire Pleistocene mayhave lasted a half-million years;perhaps much longer.Was man living inNorth America then?Did he retreat to caves and rock-shelters in the north,as he did from time to time during long ages in France and Spain?Had heprimitively adjusted himself to life on the western plains or to the desertsof our Southwest,where he was afterwards discovered through the remainsof his basket-making,his cliff-dwellings,and his places of worship?Washe already present in Yucatan,in Honduras,in the Andes,in the BrazilianBasin?Was he there as the ancient ancestor of the Maya and the Aztec?  \nWe have hints and indications,but we do not assuredly know.On theother continents our surer knowledge has largely come by way of those whodisturb the earth and the rocks,excavating for the purposes of modern man,for highways and railroads,for building materials and power plants.It issometimes said that in western Europe every person is an amateur archae-ologist,keeping an alert eye open for fossil bones and the buried works ofancient man.Although this statement is an obvious exaggeration,it suggestsa clear advantage to other countries,where the early history of man and ofother forms of life have long been matters of common and popular interest.In America we are only now building up a tradition of helpfulness as betweenthe archaeologist and the man who digs and transports soil,gravel and stone.Already our Indian archaeology has begun to profit in this way.A vigorouscampaign of informaticn,communication,and careful scrutiny of discoveredobjects is well under way.Wit","cbCaibUaOGYj5Mcs","https://ap.wps.com/l/cbCaibUaOGYj5Mcs","pdf",1372669,28,"English","# IN QUEST OF GLACIAL
