Hiram Holding was a British journeyman, tailor and early pioneer of camping. His love for the outdoors began in the 1850's when, as a 9 year old, his family joined a wagon train across the USA. He released “The Campers Handbook” in 1908 urging people embrace the outdoors. The book is an exhaustive resource full of technique and philosophy. Under "Stews and beverages" we also find his opinions on tea and the best way to make it.
Holding goes on anecdotally about the various do's and don'ts and summarises in his own comedic fashion.
"The Campers Handbook" is certainly from another time but at its core it is all valid, relevant writing. I look forward to sharing more.
