Warren County, in his eighty-ninth year when his statement was given, says: "The most active time to my knowledge was from 1816 to 1830...." In 1829 Mr. Mullin moved off the line with which he had been connected and took no further part in the work.[93] Mr. Eliakim H. Moore, for a number of years the treasurer of Ohio University at Athens, says that the work began near Athens during 1823 and 1824. "In those years not so many attempted to escape as later, from 1845 to 1860."[94] Dr. Thomas Cowgill, an aged Quaker of Kennard, Champaign County, recollects that the work of the Underground Railroad began in his neighborhood about 1824. The time between 1840 and the passage of the Fugitive Slave Law he regards as the period of greatest activity within his experience. Joseph Skillgess, a colored citizen of Urbana, now seventy-six years old, says that it is among his earliest recollections that runaways were entertained at Dry Run Church, in Ross County.[95] William A. Johnston, an old resident of Coshocton, testifies: "We had such a road here as early as the twenties, I know from tradition and personal observation."[96] Mahlon Pickrell, a prominent Quaker of Logan County, writes: "There was some travel on the Underground Railroad as early as 1820, but the period of greatest activity in this vicinity was between 1840 and 1850."[97] Finally, Mr. R. C. Corwin, of Lebanon, writes: "My first recollection of the business dates back to about 1820, when I remember seeing fugitives at my father's house, though I dare say it had been going on long before that time. From that time until 1840 there was a gradual increase of business. From 1840 to 1860 might be called the period of greatest activity."[98] Among these aged witnesses, those have been quoted whose experience, character and clearness of mind gave weight to their words. Mr. Rush R. Sloane, of Sandusky, who made some local investigations in northwestern Ohio and published the results in 1888, produces some evidence that agrees with the testimony just given. He found that, "The first runaway slave known as such at Sandusky was there in the fall of the year 1820.... Judge Jabez Wright, one of the three associate judges who held the first term of court in Huron County in 1815, was among the first white men upon the Firelands to aid fugitive slaves; he never failed when opportunity offered to lend a helping hand to the fugitives, secreting them when necessary, feeding them when they were hungry, clothing and employing them."[99] After reciting a number of instances of rescues occurring between 1820 and 1850, Mr. Sloane remarks that one of the immediate results of the passage of the second Fugitive Slave Law was the increased travel of fugitives through the State of Ohio.[100] The foregoing items have been brought together to show that there was no break in the business of the Road from the beginning to the end. The death or the change of residence of abolitionists may have interrupted travel on one or
