What was the difference between Covey and Freeland?

From the text:

But to return to Mr. Freeland, and to my experience while in his employment. He, like Mr. Covey, gave us enough to eat; but, unlike Mr. Covey, he also gave us sufficient time to take our meals. He worked us hard, but always between sunrise and sunset. He required a good deal of work to be done, but gave us good tools with which to work. His farm was large, but he employed hands enough to work it, and with ease, compared with many of his neighbors. My treatment, while in his employment, was heavenly, compared with what I experienced at the hands of Mr. Edward Covey.
