- 1852 (1923) Thus, after felling the trees, instead of chopping them into lengths, for the purpose of facilitating the operation of piling them preparatory to burning, which would have cost him too much labour, he resorted to the practice of "niggering," as it is called; which is simply laying light pieces of round timber across the trunks of the trees, and setting fire to them at the point of contact, by which means the trees are slowly burned through.
