ADMINISTRATIVE REPORT XXIH 



researches render it clear that theu' water craft was a 

 leading factor in determining their wide distribution and 

 their siiccess in making conquest of the continent up to 

 the plane of aboriginal standards. The detailed results of 

 the work are in preparation for an early report. 



In tracing the joint lines of migration and esthetic 

 development noted in other paragraphs Dr Few^kes be- 

 came impressed with the fact that among the ancestors 

 of the Hopi Indians the esthetic standards were much 

 more permanent than the industrial standards. Through- 

 out the entire course of tribal migrations retraced by his 

 researches — a course covering several distinct treks, alter- 

 nating with periods of stable settlement, the whole cov- 

 ering some centuries — the symbolic devices inscribed on 

 the fictile ware remained constant or underwent only 

 slight and easily traceable modifications, while at each 

 successive settlement new materials were utilized in the 

 potteiy making, the manufacturing processes and the 

 final forms of the ware being manifestly adjusted to the 

 character of the material. The discovery that the indus- 

 trial activities (which directly measure the conjustment 

 of man and environment) are the most progressive of the 

 entire series is not, of course, novel; still less is it novel 

 to learn that the especially conservative esthetic concepts, 

 which are at once hereditary and prophetic, as shown by 

 Groos, outlive whole generations of contemporaneous 

 industrial concepts ; yet the example is notably apposite 

 and instructive, largely by reason of the freedom of the 

 folk from external interference, with the consequent sim- 

 plicity and integrity of the record. The details are incor- 

 porated in Dr Fewkes's paper in another part of this 

 report. 



In the course of his reconnoissance of central and 

 southern Arizona Dr Frank Russell gave especial atten- 

 tion to the architectural features of the ruins, and defined 

 a number of types, of which one or two are new to south - 

 .western archeology. The work was still in progress at 

 the close of the fiscal year.
