Fighting With Smoke.

Smoke is a valuable weapon in this war; It is extensively used on both sides to mask military and naval movements, and elaborate means have been devoted to throw up clouds of smoke. A very interesting use of smoke is described thus in Scientific American: “During a poisonous gas attack smoke is employed to ward off the fumes. BeIng considerably heavier than the poisonous gases generally employed, a barrage of smoke causes the dangerous fumes to pass over trenches and dugouts and to dissipate themselves In the higher regions.”
