Melville Fuller,
Springer Land Association v. Ford…
“ The truth is that what area of land is subject to lien in a given case largely depends on the character of the improvement. The extent of ground proper and necessary to the enjoyment of a building, a wall, or a fence, would not be the same as that required for, or appertaining to, an irrigation system; but the principle of determination is the same.This ditch was to expend its waters on this tract, and could not be used or operated without it. Each was dependent on the other, and both were bound together in the accomplishment of a common purpose. ”
