The plural parts is consistently used in the original text for the olive tree allegory, but here in verse 19 the 1830 compositor accidentally set the singular part. In verse 13, Oliver Cowdery apparently made the same error during the early transmission of the text, either in 𝓞 or in copying from 𝓞 into 𝓟. See the discussion under Jacob 5:13–14 for the dialectal form nithermost as well as for why parts should be in the plural throughout Jacob 5.
