In the United States, a country lawyer, or county-seat lawyer, is an attorney who has completed little or no formal legal training and has become a member of a county bar or a state bar after "reading law"; traditionally, these lawyers practiced general law in a rural setting, or on the frontier such as Andrew Jackson.
Reading law 
The opportunity to become a lawyer without graduating law school, called "reading law", is still available in seven U.S. states (California, Maine, New York, Vermont, Virginia, Washington, and Wyoming) through various apprenticeship programs.
The life of the law has not been logic; it has been experience.
Learning law 
Unlike their U.S. counterparts, early lawyers of Canada did get some legal training, but not within a higher institution like a school. Following English tradition, early Canadian lawyers trained by "learning law" through another lawyer. To practice fully, these legal students (articled clerk) are required to pass a bar exam and be admitted to the bar.
Learning law was also used in Ontario to train lawyers until 1949. People training to become lawyers need not attend school, but they were asked to apprentice or article with a practicing lawyer. Changes in the late 1940s ended the practice.
Now the true test of the country lawyer is not the size or importance of the community in which he does his work, but rather the sort of work which he does and the sort of people for whom he does it. [...] If a lawyer performs every sort of legal service for every sort of client – the poor and the lowly as well as the rich and the well born – he is, within my definition at least, a country lawyer, and no arbitrary distinction based on density of population or the like can make him anything else.
Robert H. Jackson offered his own description in his 1950 essay "The County-Seat Lawyer":
He 'read law' in the Commentaries of Blackstone and Kent and not by the case system. He resolved problems by what he called “first principles.” He did not specialize, nor did he pick and choose clients. He rarely declined service to worthy ones because of inability to pay. [...] He never quit. He could think of motions for every purpose under the sun, and he made them all. [...] The law to him was like a religion, and its practice was more than a means of support; it was a mission. He was not always popular in his community, but he was respected. [...] He “lived well, worked hard, and died poor.” Often his name was in a generation or two forgotten. It was from this brotherhood that America has drawn its statesmen and its judges.
