Q2. What is the main point of the article?
instead of requiring evenly sized wood in order to secure good results with pyrometers, possibly by proper control the variability of the size of wood may even prove an advantage.
Q3. What is the effect of the temperature on the decomposition of wood?
Any control embodying such a conception would certainly result in a very great absence of control during the latter stages of the distillation as the decomposition of a large volume of very dry wood is likely to be extremely violent.
