Mr. J. P. Rogan continued his work as assistant until the close of November, when he voluntarily resigned his position to enter upon other engagements. A portion of his time during the first month was occupied in arranging and preparing for shipment the collection purchased of Mrs. McGlashan, in Savannah, Georgia. The rest of his time was employed in exploring mounds along the upper Savannah River in Georgia and South Carolina and along the lower Yazoo River in Mississippi. Mr. J. W. Emmert continued to act as field assistant until the end of February, when the field work closed. His labors, with the exception of a short visit to central New York, were confined to eastern Tennessee, chiefly Blount, Monroe, and Loudon counties, where numerous extensive and very interesting groups are found in the section formerly occupied by the Cherokees. Prof. Thomas thought it necessary to devote considerable attention to the ancient works of that region, as it is probable that there and in western North Carolina is to be found the key that will materially assist in solving the problem of the peculiar works of Ohio. The results of these explorations are of unusual interest, independent of their supposed bearing on the Ohio mounds. Mr. James D. Middleton, who has been a constant assistant in the division since its organization, after completing some investigations begun in southern Illinois, visited western Kentucky for the purpose of investigating the works of that section, but was soon afterwards called to Washington to take part in the office work. During the month of June he visited and made a thorough survey of the extensive group of works near Charleston, West Virginia, of which Colonel Norris had made a partial exploration, the latter having been prevented from completing it by the sickness which immediately preceded his death. During the same month Mr. Middleton commenced the survey of the Ohio works before alluded to, obtaining some valuable results in the short time before the close of the year. Mr. Gerard Fowke was also engaged for a short time in field work in western Pennsylvania, Ohio, and Kentucky, but was called early in autumn to Washington to assist in office work.
