Bouvier's Law Dictionary, Revised 6th Ed (1856):

STEALING. This term imports, ex vi termini, nearly the same as larceny; but
in common parlance, it does not always import a felony; as, for example, you
stole an acre of my land.
     2. In slander cases, it seems that the term stealing takes its
complexion from the subject-matter to which it is applied, and will be
considered as intended of a felonious stealing, if a felony could have been
committed of such subject-matter. Stark. on Slan. 80; 12 Johns. Rep. 239; 3
Binn. R. 546; Whart. Dig. tit. Slander.
