with 5 supplemental davs, this usage coincldino- with the calen- 

 dar found ill vogue at the time of the Spanish conquest. Other 

 collateral results of interest were obtained. 



Eastern archeolo(/i/ — Professor W. H. Holmes sjient the earlier 

 part nf the niDiith in organizing the work for the year. Later 

 he proceeded to different points in Delaware vallevfor the pur- 

 pose of continuing studies of ancient quarries and quarrv-shop 

 rejects in that highly interesting archeologic region. A new 

 quarry-shop was discovered within 15 miles of Trenton, yield- 

 ing abundant rejects coi'responding preciseh' with the supposed 

 paleolithic objects found in that locality. Subsequently Pro- 

 fessor Holmes proceeded to Chicago for duty in connection 

 with the final arrangement of certain groups in the World's 

 Columliiau Exposition under the immediate supeiwi-sion of the 

 Director. In the closing days of the mouth he visited a num- 

 ber of interestino' archeoloiric localities in Ohio, extending- in 

 particular his detailed observations of the Newcomerstown 

 gravels — the only case now strongly hehl to indicate the exist- 

 ence of man during the glacial period in this countr'S'. 



Mr Gerard Fowke, under Professor Holmes' general super- 

 vision and under the immediate direction of the Ethnologist in 

 Charge, proceeded to the valley of the Tennessee for the ])ur- 

 pose of making collections from the little known but liighly 

 interesting interior shell mounds found in that region. His 

 work has been successful, several cases of materials have been 

 obtained, and Mr Henrv Walthei- is now engaged in preparing 

 and marking them for deposit in the National Museum for 

 purposes of ethnologic study. 



Mr William Dinwiddie, under Professor Holmes' immediate 

 direction, spent the greater part of the month in collecting 

 materials representing the arts and customs of the Indians 

 along the shores of Chesapeake bay. While the results of his 

 work hardly equal expectations in point of quantity, much of 

 the material is of exceptional interest, and his negative determi- 

 uations are of value to the Bureau. 



Western archeohfiy — Mr Cosmos Mindeleff was occupied 

 during the earlier part of the month in outfitting- for several 

 months' work in the Puel)lo countrv; afterward he proceeded
