lie archeolog-ic collections of New York, and in -June lie vis- 

 ited Providence and Boston in search of certain rare histor- 

 ical data relating to the early life and customs of the North

 particulars. 



Mr. Victor Mindeleff sjjent most of the year in preparing 

 a rejjort on the architecture of Tusayan and Cibola, which 

 forms part of the Eighth Annual Report of the Bureau. He 

 also Avrote a report on the I'epairs and protection of the ruin of 

 Casa Grande in Arizona, on Gila river, which Avas accom- 

 panied by diagrams and plans and a series of photographs, and 

 contained a discussion of the architecture of this ruin, as com- 

 pared with that of a ruin on Rio Salado excavated by the 

 Hemenway expedition. 



During the first four months of the fiscal "s^ear, Mr. Cosmos 

 Mindeleff was occupied in revising manuscript for publica- 

 tion, and otherwise assisting Mr. Victor Mindeleff in the ^^rep- 

 aration of the paper on Pueblo architecture for the Eighth 

 Aimual Report, his own portion of the report having been pre- 

 viously finished. In December, 1889, he commenced to exe- 

 cute a series of maps, on which the location of all known ruins 

 in the ancient Pueblo country will be plotted. Tlie maps 

 were in large part drawn, and the plotting of the ruins was 

 commenced. AVlien completed, the maps will show the distri- 

 bution of all ruins in that region, which are mentioned in liter- 

 ature or known to explorers, and will be accompanied by a 

 catalogue containing a description of each ruin and references 

 to the literature relating to it, the whole forming an exhaustive 

 record. It is intended to present this work in one of the future 

 publications of the Bureau. 



During- the year the work of the modeling room Avas con- 

 tinued, under the direction of Mr. Cosmos Miudeleft", 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 sections for convenience 

 of shipment, and boxed. A duplicate of a model of the ])ueljlo
