He calculated that, based on a mixture of softwoods and hardwoods 40 feet tall and inches in diameter, it would take a rough average of 24 trees to produce a ton of printing and writing paper, using the kraft chemical freesheet pulping process.
Rosin, alum or combination of other chemicals is used to make paper water resistant.
