ADMINISTRATIVE KEPOKT. XXIX 



B(itetourt, Bath. Alleghany, and Highland fuuuties. He then 

 began an examination of the prehistoric remains of Shenan- 

 doah valley, remaining in the field until December. Later he 

 examined the islands and coast between Savannah and St. 

 Johns rivers, locating mounds and shell heaps. In the spring 

 he resumed work in Shenandoah valley, making a careful and 

 thorough investigation of every county. The results show 

 that this region was not the seat of permanent occupancy 

 by the aborigines, though it seems to have been a place of 

 resort for hunters in large numbers. 



Mr Williani Dinwiddie was engaged during the year in 

 mapping and examining the shell banks and other aboriginal 

 remains of the Potomac-Chesapeake region. 



As Dr Cyras Thomas was engaged most of the time during 

 the year in necessary office work, his field work was limited. 

 Finding more accurate information desirable in reference to 

 certain ancient works in Vanderburg county, Indiana, he 

 engaged Mr F. W. Wright to make a careful survey and meas- 

 urement of them. As the result showed that they Avere of 

 unusual importance on account of their peculiar character as 

 compared with other ancient works of the same section, Dr 

 Thomas found it necessary to make a personal examination of 

 them. During the same trip he examined certain important 

 mounds in Illinois, among which was the noted "Cahokia" or 

 "Monk's Mound," of Madison county. His object in this case 

 was to ascertain the present condition of this remarkable mon- 

 ument, and to investigate certain other points in relation to 

 which satisfactory conclusions could be reached only by per- 

 sonal inspection. 



He also made during the summer another examination of 

 the Newark works and Fort Ancient, in Ohio, in order to 

 settle some points which previous reports had overlooked. At 

 his suggestion the Director had a resurvey made, under the 

 dii'ection of Mr Henry Gannett, of the four most noted circles 

 of the Ohio woi'ks, the planetable being used to show their 

 exact form as they at present appear. 



Mr F. H. Cushing, during the suimuer and autunm months 

 of 1891, made some examinations on the shore of Lake Erie,
