ROTFLMAO!!!!!!!!!!!
This thread is hysterically funny. I am literally still laughing as i write this.
Sorry, I've been out or I would have saved you all the embarrassment trouble and answered sooner. To settle the question - a quarter section is 1/4 of a section which is 1 mile square - 1 mile on each side. 1/4 of that is 1/2 mile on each side. A section is a standard unit of measure in land surveying which I learned in college in archeology classes. Sections are also extensively used in the agricultural world too, as well as topographic maps. Sections are those square boxes on topo maps.
1 mile square is 640 acres, therefore a quarter section is 160 acres. My ranch was 146 acres or slightly less than a quarter section.
PS: The "South 40" references were to fields of 40 acres m/l
Sorry, better define that - m/l means "more or less", in other words, it might actually survey out to 39.67 acres or 40.12 acres, but for advertising 40 acres m/l is sufficient.
