"_Oct. 1859._ U. G. R. R. Conductor reported the passage of five, who were considered very valuable pieces of Ebony, all designated by names, such as _John Brooks_, _Daniel Brooks_, _Mason Bushrod_, _Sylvester Lucket_ and _Hanson Gause_. Have understood also that three others were ticketed about midsummer." In Ohio, Daniel Osborn, of the Alum Creek Quaker Settlement, in the central part of the state, kept a diary, of which to-day only a leaf remains. This bit of paper gives a record of the number of negroes passing through the Alum Creek neighborhood during an interval of five months, from April 14 to September 10, 1844, and is of considerable importance, because it supplies data that furnish, when taken in connection with other terms, the elements for an interesting computation of the number of slaves that escaped into Ohio.[20] In the correspondence of Mr. David Putnam, of Point Hamar, near Marietta, Ohio, there were found a few letters relating to the journeys of fugitives. That even these few letters remain is doubtless due to neglect or oversight on the part of the recipient. It is noticeable that some of them bear unmistakable signs of intended secrecy, the proper names having been blotted out, or covered with bits of paper. [20] See Chap. XI, p. 346. Underground managers who were so indiscreet as to keep a diary or letters for a season, were induced to part with such condemning evidence under the stress of a special danger. Mr. Robert Purvis, of Philadelphia, states that he kept a record of the fugitives that passed through his hands and those of his coworkers in the Quaker City for a long period, till the trepidation of his family after the passage of the Fugitive Slave Bill in 1850 caused him to destroy it.[21] Daniel Gibbons, a Friend, who lived near Columbia in southeastern Pennsylvania, began in 1824 to keep a record of the number of fugitives he aided. He was in the habit of entering in his book the name of the master of each fugitive, the fugitive's own name and his age, and the new name given him. The data thus gathered came in time to form a large volume, but after the passage of the Fugitive Slave Law Mr. Gibbons burned this book.[22] William Parker, the colored leader in the famous Christiana case, was found by a friend to have a large number of letters from escaped slaves hidden about his house at the time of the Christiana affair, September 11, 1851, and these fateful documents were quickly destroyed. Had they been discovered by the officers that visited Parker's house, they might have brought disaster upon many persons.[23] Thus, the need of secrecy constantly served to prevent the making of records, or to bring about their early destruction. The written and printed records do give a multitude of unquestioned facts about the Underground Railroad; but when wishing to find out the details of rational management, the methods of business, and the total amount of traffic, we are thrown back on the recollections of living
