records to be processed for incorporation into the files but also, be- 

 cause of an attendant shift in emphasis to preparation of technical 

 archeological reports, in the need for many photographs, maps, and 

 profiles for illustrative use in the resultant publications. As persons 

 qualified to perform this task were available, drawings of artifacts 

 were made to supplement the photographic presentation. Approxi- 

 mately 1,100 such drawings, mostly of specimens from sites in Medi- 

 cine Creek, Boysen, Angostura, and Oahe Reservoirs, were completed. 

 Photographs of specimens for use in plates made up a larger propor- 

 tion than previously of the more than 3,600 negatives processed and 

 the 13,000 contact prints and 500 enlargements made. The approxi- 

 mately 1,000 color transparencies added to the files were, on the other 

 hand, almost exclusively made in the field. In the drafting depart- 

 ment, scores of maps, ground plans, profiles, and other drawings were 

 made for inclusion in final reports, in addition to maps for appraisals 

 and the inking and tracing of field drawings for preservation in the 

 permanent record files. 



The time of the archeologists in the laboratory was spent on ap- 

 praisal statements or detailed archeological reports, depending upon 

 the nature of their field activities. Because of the preponderance of 

 excavation in the field program, by far the greater effort was ex- 

 pended on detailed analysis of specimens and writing of technical 

 reports. 



A number of mimeographed appraisals, containing recommenda- 

 tions for salvage in reservoir areas investigated, were transmitted to 

 the National Park Service, while others were nearly ready for distri- 

 bution as the period ended. Preliminary appraisals of Bixby Reser- 

 voir, South Dakota; Moorhead Reservoir, Montana and Wyoming; 

 Rockyford Reservoir, South Dakota; and Onion Flat, Raft Lake, 

 and Soral Creek Reservoirs, Wyoming, were distributed in January 

 1950. They had been completed in December 1949. Similar state- 

 ments prepared and distributed during the period were on the Sun 

 River Basin, Montana (including Nilan and Wilson Reservoirs) ; 

 the Jefferson River Basin, Montana (Apex, Brenner, Clark Canyon, 

 Kelley, and Landon Reservoirs) ; the Niobrara Basin, Nebraska (Col- 

 well, Crookston, Eli, Kilgore, Long Pine, Meadville, Merritt, Ponca 

 Creek, Sparks, and Thacher Reservoirs) ; Keyhole Reservoir, Wyo- 

 ming; Lovewell Reservoir, Kansas; and Narrows Reservoir, Colo- 

 rado. Preliminary appraisals of Alzada Reservoir, Wyoming, and 

 Little Bighorn Reservoir, Montana, were nearly ready for duplica- 

 tion on December 31, 195 1. In addition, a supplementary appraisal 

 of the Moorhead Reservoir was written and transmitted.
