The following may serve for the guidance of seamen, whose attention is called to the fact that a very small quantity of oil...
Sivu 15 - On free waves, ie, waves in deep water, the effect is greatest. 2. In a surf, or waves breaking on a bar, where a mass of liquid is in actual motion in shallow water, the effect of the oil is uncertain, as nothing can prevent the larger waves from breaking under such circumstances, but even here it is of some service.
