This tea quotation comes from the "The New Way of the Wilderness" written by Calvin Rutstrum in 1958. Rutstrum is a "wilderness voyager" - a man who spent most of his life in the wilderness. Like lots of outdoorsmen Rustrum is a coffee fan but in the wilderness tea wins out...
He then goes on to pragmatically describe how he makes his tea in the bush.
"The New Way of the Wilderness" is a classic read; there will be more to come from within its pages.
