Ancient Earth Forts of the Cuyahoga Valley, Ohio #246576

Capt. Heart assisted in building Fort Harmar, at the mouth of the Muskingum river. He was evidently a'man of education, and had served in the Revolutionary army. His survey was made while the ground was yet covered with a heavy growth of forest trees. In 1801, the Rev. Mr. Harris, while on a tour through the Ohio country, resurveyed them and inserted an engraved plan in his published Journal. Caleb Atwater, Esq., of Circleville, Ohio, made the first general survey of the Ohio Earth Works in 1819, under the auspices and at the expense of the American Archaeological Society, at Wor cester, Mass. His plans and descriptions fill an important portion Of the first volume of their transactions, published in 1820. When the first Geological Survey of Ohio was in progress, I continued the survey Of the newly discovered works, intending to make the subject of our antiquities a part of the final report.
