Doctors were mostly hunters, consequently the hunter was not necessarily an ignorant man, still, in a population of many thousands, the exceptions might have appeared quite numerous. As a rule he became a man of extensive information, and hunted, not as a primitive Darwin-tailed quadruped “making a struggle for life with a club,” yet it was to supply the necessities of existence all the same. Subsistence was, however, easily obtained, and did not tax much of his time, and he had abundance of leisure to devote to experiment and observation. He was a worker in the vineyard, with the naturalist, geologist, botanist, biologist, archæologist, etc., and the aggregate co-operative labor accomplished became manifestly incalculably great. With object lessons daily before him, in due time he became familiar with the habits, instincts, intelligence and peculiarities of beasts, birds and insects, as well as acquainted with the geology, mineralogy and botany of the district in which he resided. Nothing escaped observation, from a spear of anemone to the spreading oaks of the forest. The names of all beasts, birds, plants and minerals with characters, habits and qualities could be given by the accurate and extensive observers and investigators who were found among resident squirrel hunters. [Illustration: Hunter and Dog.] The man with dog and gun could answer all questions; was the only encyclopedia the collector had to consult; the formulator of scientific facts desired no other, could ask for no better. The Doctor in early days, was a man of science and literary attainments. And his avocation brought him in contact with the hunter and his valuable collections, observations and investigations, and in this way became the safety deposit of facts relating to natural history and collateral branches; in fact, the medical profession constituted a small army of zealous collectors and investigators--such men as Doctor Ezekiel Porter, president of the first medical society in Ohio; Doctors Eliphas Perkins, John Cotton and Samuel P. Hildreth, of Washington County; Doctors Ebenezer Bowen, Chancy F. Perkins and Columbus Bierce, of Athens County; Doctors Robinson and James S. Hibbard, of Meigs; Doctors Felix Reignier and J. G. Hamlin, of Gallia; Doctor Giles S. B. Hempstead, of Scioto; Doctor Alexander M. Millan, of Morgan; Doctor Joseph Whipple, of Hocking; Doctor Joseph Scott, of Madison; Doctor Ezra Chandler, of Muskingkum; Doctor Jared P. Kirtland, of Cuyahoga, and others equally well known and respected in other parts of the country and who were equally identified with the history of the state.
