In the hard and cruel life of the border, with its grim struggle against the forbidding forces of wild nature and wilder men, there was much to pull the frontiersman down. If left to himself, without moral teaching and moral guidance, without any of the influences that tend toward the uplifting of man and the subduing of the brute within him, sad would have been his, and therefore our, fate. From this fate we have been largely rescued by the fact that together with the rest of the pioneers went the pioneer preachers; and all honor be given to the Methodists for the great proportion of these pioneer preachers whom they furnished.Theodore Roosevelt, 26 Feb 1903, at the bi-centennial celebration of the birth of John Wesley
For over half a century, “the whole powers of (Rev. Ezra Adams’) mind were absorbed in the great work of saving souls” on the Canadian frontier. 
The Methodist Episcopal Church was founded in the United States in 1784. As the country expanded west, the Church expanded with it. Conferences, many aligned with one or more states, and comprised of several districts, were organized to direct its activity over an area. Districts of the New York Conference initially covered Canada. In 1810, the districts covering northern-most New York and Canada were organized into the Genesee Conference. In 1824, the districts covering Canada were organized again into the Canada Conference.
Each Conference met in Annual Conference—usually in the late summer, presumably for ease of travel. As the members of the Annual Conference were the itinerant preachers, Ezra presumably traveled from Canada to some of these conferences in northern New York between 1814–1824.
At the Annual Conference, the Conference bishop assigned itinerant preachers to a circuit for the next year. From the minutes of these conferences, it appears the preachers left the Annual Conference, and immediately headed to their newly assigned circuit.
Beginning in 1824, the Canada Conference severed ties with the Methodist Episcopal Church, and in 1833 joined with the British Wesleyans to form the Wesleyan Methodist Church in Canada. Ezra would have then no longer traveled to the United States, instead attending Annual Conferences with the Wesleyan Methodist Church in Canada.
Circuit riding was difficult and dangerous work. Large numbers of them retired or died early. Ezra was designated superannuated three times during his career, and again at the end of his career.
“Superannuated Preachers are ministers in the Methodist churches who, by reason of age, infirmity, or afflictions, are disabled from preaching, but remain members of the Annual Conferences.” 
Ezra’s assigned stations are listed below. [1, 3, 4, 5, 6, 7] The dates are from Annual Conference (late summer) to subsequent Annual Conference. Over his career, his circuits spanned 500 miles of southern Ontario, Canada, as far east as Ottawa, and as far west as Lake St. Clair (near Detroit). Here, we find the townships were his children were born, and where they met their future spouses. And we observe that he probably named his third child William Case Adams after Rev. William Case.
