How do you go to the bath room in the woods?

I don't know how many times we have been asked during school visits, "How do you go to the bathroom?". Well in this excerpt Calvin Rustrum explains to his two travel companions from Chicago how they should go to the bathroom. Let us know if you think we should try his method!

"I hustled them out of bed, sleepy-eyed and apprehensive, two hours before daylight on a not too cold, clear, star-studded morning. Days are short and nights long in the Northern winter. Breakfast was eaten leisurely with many cups of coffee, while I laid down a brief for the day's activities ahead, even explaining how they might go about most comfortably performing their urgent body functions in subzero temperatures and sown that could be waist-deep. A square of turned-up birch bark is used as receptacle, the function performed in it inside the warm tent, and immediate disposition made in the wood stove. The bark creates a quick hot flame, and with ventilation no factor in the tent, all is sans gene."
