REPORT OF THE SECRETARY. 53 



During the year Mr. Victor Mindeleff was engaged upon a report on the architect- 

 ure of Tusaj^an and Cibola. This work was interrupted by a short field trip to the 

 ruin of Casa Grande, as mentioned under the head of field ■nork, and was resumed on 

 his return from that trip. The report, together with the data for its illustrations, 

 has been finished for publication. A report was also prepared on the repairs and 

 protection of the ruin of Casa Grande, on the Gila River, in Arizona. This I'eport 

 was accompanied bj"^ diagram, plans, and a series of photographs. He also was occu- 

 pied in an architectural discussion on this ruin, together with one on the ruins on 

 the Rio Salado, excavated by the Hemenway expedition, which were visited by him. 



During the first four months of the fiscal year Mr. Cosmos Mindeleff was engaged 

 in revising manuscript and otherwise assisting Mr. Victor Mindeleff in the prepara- 

 tion of a report on Pueblo Architecture, his own portion of the report having been 

 previously finished. The report was handed in for publication in December, 1889. 

 He then commenced the preparation of a series of maps, upon which the location of 

 all known ruins in the ancient Pueblo country will be plotted, in order to show their 

 distribution. The maps were partly done and the plotting of the ruins was com- 

 menced. When completed the maps will show the location of all ruins mentioned in 

 literature or known to explorers and will be accompanied by a card catalogue con- 

 taining a description of each ruin and reference to the literature relating to it, the 

 whole forming a valuable record. It is intended that a r^sum6 of this shall be pub- 

 lished. 



During the year the work of the modelling room was continued under the direction of 

 Mr. Cosmos Mindeleff, and was confined almost entirely to the enlargement of the 

 "duplicate series," referred to in previous reports. The large model of Penasco Blanco, 

 one of the Chaco ruins, reported last year as commenced, was completed, cut into sec- 

 tions for convenience of shipment, and boxed. A duplicate of a model of the Pueblo 

 ofTewa, the original of which was made in 1833, was finished and exchanged for the 

 original in the National Museum. The original was condemned and destroyed and 

 another duplicate was made for the duplicate series. A duplicate was also made of a 

 model of Schumepovi, and the original was put in order and added to the series. A 

 duplicate of a model of the Pueblo of Shipaulovi was also finished and added to the 

 same series. The original model of Casa Blanca cliff ruin was withdrawn from the 

 Museum, and a number of duplicate casts were made, one of which was finished and 

 re-deposited in the Museum. Duplicates were also made of models of Great Elephant 

 Mound, Great Etowah Mound, and two others. In the latter half of the fiscal year 

 work was commenced on the duplication of two very large models, one of Wal^ji and 

 the First Mesa, the other of Mummy Cave cliff ruin. The original models had been 

 very hurriedly made for the New Orleans Exposition, and, being cast in plaster of 

 paris, had suflered considerably in transportation. An attempt was made to cast the 

 models in paper, and in both cases the attempt was very successful. The first dupli- 

 cate of the Walpi model was completed and deposited in the National Museum, to 

 replace the original which was destroyed. The finished model weighed about 500 

 pounds, instead of 2,500 pounds, the weight of the original. The model of the 

 Mummy Cave was cast, but was not finished at the close of the year. A second dupli- 

 cate of Walpi, for the duplicate series, was cast, but not finished, at the close of the 

 year. It will be divided into sections for convenience of shipment. Toward the 

 close of the year work was commenced on two new models which will be used to 

 illustrate a report of Mr. Holmes, upon his work of the Archjeology of the District 

 of Columbia. 



But one demand was made during the year upon the duplicate series. This was 

 for a number of transparencies' to be exhibited as a part of the display of the United 

 States at the Paris Exposition. Sixty of these larg« photographs on glass were sent 

 and two grand prizes were awarded them. Upon the conclusion of the exposition 

 the transparencies were returned, and some damage suffered in transportation was 

 made good by the United States Commission.
