Experiments which have shown that the presence of carbon dioxide gas is favourable to plant life have been carried out in Germany. The exhaust gases from an internal combustion en. gine plant at a blast furnace were caused to act upon vegetation, and the result was a great increase in yield. It actually suggested a way of regenerating burned coal. It in a sense established a reproduction of the carboniferous era. It was calculated that a blast furnace producing 1000 tons of pig lion per day could supply gas for the cultivation nf 4000 tons of potatoes.
