278 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



lustrations secured by photography, and then reproduced by 

 photo-lithographic processes, have done much to popularize 

 and render familiar the leading features of the subject, show- 

 ing as they do all the phases of the eccentric methods of 

 these ancient builders, have made them an authority, and 

 they have already been reproduced in a number of late pub- 

 lications. 



The first trip proving so successful, Mr. Jackson was dis- 

 patched again this season to the same region, with instruc- 

 tions to ascertain as far as possible the extent and distribu- 

 tion of these ruins north of the present Moquis Pueblos. 

 Associated with him in the enterprise was Mr. E. A. Barber, 

 special correspondent of the New York Herald. A guide, 

 two packers, and a cook constituted the whole party; and 

 then, with six weeks' supplies laid in, the party started out 

 from Parrott City, at the head of the Rio La Plata, August 

 27th, the general course beins; down the Rio San Juan to 

 the De Chelly, up that to near Fort Defiance, and then over 

 to the seven Moqui " Cities." Returning, they crossed the 

 San Juan at the mouth of the De Chelly, and traveled north- 

 ward to midway between the Sierra Abajo and La Sal, and 

 then returned to the starting-point across the heads of the 

 canons which run southward to the San Juan. 



The Upper San Juan, Mesa Verde, and El Late regions 

 came within the area assigned Mr. "W. H. Holmes, who, in 

 addition to his geological investigations, made a special ex- 

 amination of the archaeology of his region, bringing out 

 with his ready and artistic pencil even more wonderful ruins 

 (of the same general class however) than were found by 

 Mr. Jackson the previous season. 



Traveling westward to the head of the wash of the Mc- 

 Elmo, a day was spent in the further investigation of that 

 interesting locality. A number of new ruins were discov- 

 ered, but in no way differing from those already figured. 

 The extreme heat of the atmosphere and the aridity of the 

 country prevented more than a superficial examination of 

 the many side canons which debouch into the main one, 

 only enough to determine satisfactorily that ruins were to 

 be found only in those canons which had alluvial bottoms 

 or in the near vicinity of tillable land. This fact held good 

 in the other reo-ions, for in no case could a single vestige of
