I soon made them out, and saw them riding on without stopping until out of sight. Convinced that they had really gone away, I was on the point of returning when I saw two of them, as I supposed, coming back, spurring their horses over the level road. It was a question whether I could reach the house before them. I ran as fast as my legs could carry me until I got to another point whence I could take a look at them without being seen. I then saw by their dress and the colour of their horses that they were not the men I fancied, but that one of them was Uncle Denis, while the other was a stranger. I therefore ran down the hill to meet them. "What has happened up at the farm, Mike?" asked my uncle, after we had exchanged greetings; "we met just now three of Bracher's men, who were swearing away at your father and all of you in a fashion which made me fear that they had either done some mischief, or intended doing it. I don't think they knew that we were coming here, or they would have picked a quarrel with us, for which they seemed very much disposed." I relieved my uncle's mind by telling him that the men had only used threatening language, but I thought it prudent not to say that the fugitive slave was actually in the house, not knowing the character of the stranger who was with him. My uncle now introduced him to me as Mr McDermont, a countryman, who said he had come over to settle in the States, and who, not yet having any experience as a backwoodsman, had determined on purchasing an improved farm. "I offered him mine, but he does not wish to employ slave labour, and would prefer obtaining one in a free state. I therefore brought him here, feeling sure that your father would gladly assist him in finding the style of location he desires." Uncle Denis and his companion were, of course, heartily welcomed at Uphill. "I am so thankful that you have come, Denis," said my mother, who had been much alarmed at the late occurrence, "do, pray, remain and assist my husband in defending our property, for I dread lest those men should carry their threats into execution!" Uncle Denis did his best to reassure her, saying that he did not think Mr Bracher would venture on any act of violence, but promising to stay some time at Uphill, until Mr McDermont had settled in the neighbourhood.
