[Illustration: SIMPLE ROUTE THROUGH LIVINGSTON AND LA SALLE COUNTIES, ILLINOIS. Drawn by William B. Fyffe.] From a drawing made by Mr. W. B. Fyffe, an old-time station-agent of Ottawa, Illinois, the accompanying chart of a line of escape through Livingston and La Salle counties in Illinois is reproduced. The portion of the trail represented is about forty miles in length, and is remarkable for the directness of its course and the absence of interlacing lines. At Ottawa, the northernmost station shown, the trail loses these two characteristics, for it makes there a sharp turn on its way to the terminus, Chicago, and at Ottawa also it makes a junction with several other lines from the western part of the state.[437] [437] For these features see the general map. A number of noteworthy features appear on the general map. The first deserving mention is the direction or trend of the underground lines. The region traversed by these lines may be described as an irregular crescent, the concavity of which is in part filled by a portion of Ontario, Canada, which by reason of its proximity became the goal of the great majority of runaways. In the New England states the direction of the underground paths was, with perhaps an exception or two, from southeast to northwest, their objective point being Montreal. The main lines of Pennsylvania and New York ran north until they reached the middle part of the latter state, and then veered off almost directly west to Canada. West of Pennsylvania the trend of the routes was in general to northeast, being in Ohio and Indiana to the shores of Lake Erie, and in Illinois and Iowa to the southern extremity of Lake Michigan. Through central Iowa, northern Illinois and southern Michigan, the course of the routes was almost directly east. [Illustration: NETWORK OF ROUTES THROUGH GREENE, WARREN AND CLINTON COUNTIES, OHIO.]
