The Underground Railroad system was never so successful in all its history as after 1850. Despite the law, and the infamous activities of many of the slave-catchers, at least 3,000 fugitives got through to Canada within three months after the bill was signed. This was the estimate of both Henry Bibb and Hiram Wilson and there were probably no men in Canada who were better acquainted with the situation than these two. In _The Voice of the Fugitive_ of November 5, 1851, Bibb reported that "the road is doing better business this fall than usual. The Fugitive Slave Law has given it more vitality, more activity, more passengers and more opposition which invariably accelerates business.... We can run a lot of slaves through from almost any of the bordering slave states into Canada within 48 hours and we defy the slaveholders and their abettors to beat that if they can.... We have just received a fresh lot today and still there is room." _The Troy Argus_ learned from "official sources" in 1859 that the Underground Railroad had been doing an unusually large business that year.[19] Bibb's newspaper reports, December 2, 1852, that the underground is working well. "Slaveholders are frequently seen and heard, howling on their track up to the Detroit River's edge but dare not venture over lest the British lion should lay his paw upon their guilty heads." Bibb kept a watchful eye on slave-catchers coming to the Canadian border and occasionally reported their presence in his paper. Underground activity was also noted in _The Liberator_. "The underground railroad and especially the express train, is doing a good business just now. We have good and competent conductors," was a statement in the issue of October 29, 1852.[20]
Not all those who fled to Canada left their property behind. _The Voice of the Fugitive_ makes frequent reference to Negroes arriving with plenty of means to take care of themselves. "Men of capital with good property, some of whom are worth thousands, are settling among us from the northern states." says the issue of October 22, 1851, while in the issue of July 1, 1852, it is noted that "22 from Indiana passed through to Amherstburg, with four fine covered waggons and eight horses. A few weeks ago six or eight such teams came from the same state into Canada. The Fugitive Slave Law is driving out brains and money." In a later issue it was stated "we know of several families of free people of color who have moved here from the northern states this summer who have brought with them property to the amount of £30,000."[21] Some of these people with property joined the Elgin Association settlement at Buxton, purchasing farms and taking advantage of the opportunities that were provided there for education. A letter to _The Voice of the Fugitive_ from Ezekiel C. Cooper, recently arrived at Buxton, says: "Canada is the place where we have our rights."[22] He speaks of having purchased 50 acres of land and praises the school and its teacher at Buxton. Cooper came from Northampton, Massachusetts, driven out by the Fugitive Slave Law. A rather unusual case was that of 12 manumitted slaves who were brought to Canada from the South. They had been bequeathed $1,000 each by their former owner. They all bought homes in the Niagara district.[23]
