REPORT OF THE SECRETARY. 63 



As the work of writing up the report from the fleld-notes, exaiuiuing 

 the collections, and preparing the plats and illustrations proceeded, it 

 was found that here and there were omissions in the original examina- 

 tions which left the details of certain sections incomplete. It therefore 

 became necessary to close these gaps as far as possible. The most im- 

 portant hiatus was filled by an examination of the lake border of the 

 United States from Detroit westward to the head of Lake Superior, to 

 ascertain whether the historic Indian localities along that line were 

 marked by mounds or other ancient works. 



Another undertaking which had been begun during the last month 

 of the preceding year was a survey of certain inclosures and other an- 

 cient remains of Ohio, to test the reliability and accuracj^ of the surveys 

 made by Squier and Davis and others. This was continued during a 

 portion of the past year. 



A third item consisted in completing, as far as possible, the list of 

 mound localities to be used in prei)aring the maps. 



During the year the assistants were JNIessrs. James D. Middleton, 

 Gerard Fowke, and Henry L. Eeyuolds. 



On July 15 Messrs. Middleton and Fowke went to Ohio, where they were 

 engaged about one mouth in surveying the ancient works of that region. 

 During the same time Mr. Reynolds was employed in the same State 

 collecting data for the archaiologic maps. From Ohio Mr. Fowke went 

 to Michigan, making the tour of the lake border of the United States 

 from Detroit westward to Dnluth at the head of Lake Superior. He 

 made careful exannnations for ancient works and aboriginal remains, 

 especially at the following-named points : Detroit ; Port Huron ; Sagi- 

 naw ; Ogemau County; about Traverse Bay; Beaver Island; Mackinac 

 Island and the main land on both sides; Sault Ste. Marie; Marquette; 

 Munissing; the copper region; Ontonagon; Ashland; Bayfield; La 

 Pointe (the Old Chaquamagon), and Dnluth. Eetnrning by way of 

 Prairie du Chien, Wis., and Davenport, Iowa, he stopped at Carbon- 

 dale, 111., the i)oint selected as headquarters for the season. After 

 writing out a preliminary re[)ort of his trip he went to Kentucky to 

 examine certain works in the northern i)art of that State, and thence 

 to Washington. During May and June, 1888, he was engaged in ex- 

 ploring mounds in Pike County, Ohio. 



From Ohio Mr. Middleton went to Wisconsin to survey certain groui)s 

 of works in the southern and southwestern part of that State, which 

 occupied him until autumn. He then went to Carbondale where he was 

 engaged most of the winter in working up the i)lats and other results 

 of his surveys. Before the close of the winter he made a survey of 

 certain groups in southeastern Missouri and of the Seltzertown group 

 in INIississippi. During April, May, and June he was engaged in sur- 

 veying and examining groups in southern Ohio and northern Kentucky. 



Mr. Keynolds, after leaving Ohio, was engaged during the remainder 

 of the summer, and until ho went to Carbondale in autumn, collecting
