[637] Howe, _Refugees from Slavery in Canada West_, p. 69. The movement was normally from these and other centres on the lake shore, or near it, to the interior. How rapid it was we can only judge by the few chance indications that remain. During Drew's travels in Canada West he learned that in 1832 the town of Chatham was a mere hamlet comprising a few houses and two or three shops, although the oldest deed of the place on record is dated 1801. Steamboats did not begin to ply on the river Sydenham between Chatham and Detroit until 1837. But long before this year, and, in fact, at the first settlement of the town, colored people began to come in.[638] When Levi Coffin made his first trip to Canada, in 1844, he visited a number of settlements of colored people scattered along the river Thames north of Dawn, and found the colony at Wilberforce already established.[639] This colony had been founded as early as 1830, and because it was originally settled by a group of emancipated slaves, it soon began to attract new settlers from the incoming stream of runaways. By 1846 the more distant interior was invaded. In that year the long strip of country stretching from the western extremity of Lake Ontario across to Lake Huron, and designated on the general map as Queen's Bush, was entered by pioneers who had escaped from slavery. This region was not surveyed until about 1848, and by that time there were as many as fifty families located there.[640] Some time during the years 1845 to 1847, the Rev. R. S. W. Sorrick went as far north as Oro, where he found "some fifty persons settled, many comfortable and doing well, but many [suffering] a great deal from poverty."[641] The surveying of the tract called Queen's Bush, and the subsequent arranging of the terms of payment for land already occupied, caused a number of colored settlers to sell their clearings in "the Bush" and move away. Some of these, it appears, went south to Buxton, but some went north to the shores of Georgian Bay and located at Owen Sound.[642] From this testimony it is certain that by 1850 fugitive slaves had found their way in considerable numbers throughout the inter-lake portion of Canada West.
