Joseph McKenna, McCaskill Company v. United States…
“ Residence and cultivation of the land are the price that is exacted for its payment. It is in the power of the settler to modify the terms somewhat. He may substitute for a residence and cultivation for five years a residence and cultivation for not less than fourteen months; but he must make 'proof of settlement and of residence and cultivation for such period of fourteen months,' and pay the price provided by law for the land entered. This is known as the 'commutation' of his homestead entry. ”
