On the ridge may be seen the exhaust ' air-pump' of the same firm. Gas may also be employed for extracting impure air by being placed under suitable tubes for this purpose. One cubic foot of gas will extract 3,000 cubic feet of air, and as an ordinary burner uses five cubic feet per hour 15,000 cubic feet per hour may in this way be got rid of. Gas is not always available, but we are not limited to this, there are other methods by which stables and cow- Digitized by Microsoft®.
