REPORT ON NATIONAL MUSEUM. 261 



Lawrence C. Johnson. He bas sent sixty-two boxes of fossils during the 

 year 1883. 



Some interesting collections were made by my own party during last 

 season, but they are not so important as they were last year. 



Routine work. 



Mr. John B. Marcou having been appointed my assistant upon the 

 Geological Survey, I have placed him in charge of the Museum work 

 of my division. 



The present demands of the Survey has almost entirely prevented 

 work upon the installment of the collections ; but the ordinary routine 

 work of receiving and recording accessions has been attended to. The 

 accessions from miscellaneous sources during the year have been mainly 

 unimportant. 



The register-numbers of entries for the year are from 11,886 to 12,230. 



Present state of the collections. 



The arrangement of the collections has not progressed far enough to 

 allow of any detailed report. They are still in the unit trays of the 

 table-cases, iu the west-south range, where they are in a safe condition. 



Recommendations. 



The work of the Survey and Museum is so rapidly increasing in my 

 div^ion that certain wants are becoming urgent. Near a hundred boxes 

 of fossils are yet unopened, and we are now in want of suitable facili- 

 ties for arranging those which are now opened. We need more unit 

 and pasteboard trays, as well as racks for the former. I respectfully 

 request also that I be furnished with a competent person whose duty it 

 shall be to record and mark specimens with their numbers as the same 

 are turned over to the Museum from the survey and elsewhere.

Accessions. 



The most important addition to the collection of Paleozoic inverte- 

 brate fossils during the year was that of the first series of duplicates 

 from the James Hall collection of the American Museum of Natural His- 

 tory, New York. This collection was received before my appointment 

 as curator, but had not been unpacked or recorded. It is now arranged 

 in drawer cases, and will serve as the nucleus for the systematic arrange- 

 ment of the collections from the regions east of the Eocky Mountains,
