REPORT OF THE SECRETARY. 63 



As tli(; work of writing up the report from the field-notes, examining 

 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 inclosnres and other an- 

 cient remains of Ohio, to test the reliability and accuracy 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 preparing the maps. 



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

 Gerard Fowke, and Henry L. Eeynolds. 



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

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

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

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

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

 from Detroit westward to Duluth at the head of Lake Superior. lie 

 made careful examinations for ancient works and aboriginal remains, 

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

 naw; Ogeman 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 Duluth. Eeturning by way of 

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

 dale, 111., the point selected as headquarters for the season. After 

 writing out a preliminary report of his trip he went to Kentucky to 

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

 to Washington. During Maj- and June, 1888, he Avas engaged in ex- 

 ploring mounds in Pike County, Ohio. 



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

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

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

 engaged most of the winter iu working up the plats 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 groui> 

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

 veying and examining groups in southern Ohio and northern Iveutucky. 



Mr. Eeynolds, after leaving Ohio, was engaged dining the remainder 

 of the summer, and uutil he went to Carbondale in autumn, collecting
