Added to historical studies regarding the practice of slash-and-burn was information essential to this question provided by toponyms. This relates to locality and terrain names created from the verbs zarzyć, zec, gorzeć, “to set fire to, to burn”. Besides the fact that names of the type Zgorzelec, Zary, Zagań speak directly of burning, they move the chronology of slash-and-burn, as documented by historians only on the basis of toponyms Laz, Lazy and derivatives, back more than two centuries. The toponyms cited in this article depict a scale for making use of new land under cultivation by burning, and they also demonstrate that slash-and-burn, which changed its original character over time, was transferred from areas of forests and woods to terrain with thickets and to wastelands, and filled there only an auxiliary function. An attempt is also made in the article to turn attention to the possibility of reconstructing unattested appellatives that designated the duties of groups of people employed in burning off sections of forests and wooded areas. Taken as the basis for such a reconstruction are selected personal names that could have originated in a process of onomyzation of hypothetical appellatives that designated those performing their respective duties.
