A load of cotton, for example, tightly screwed while in certain conditions, has been known, through the expansion of its bulk, to rend a vessel asunder at sea.

There can be no doubt either that the same result would ensue in the case of tobacco, while undergoing its usual course of fermentation, were it not for the interstices consequent upon the rotundity of the hogsheads.
It is when a partial cargo is received that danger is chiefly to be apprehended from shifting, and that precautions should be always taken to guard against such misfortune.

Only those who have encountered a violent gale of wind, or rather who have experienced the rolling of a vessel in a sudden calm after the gale, can form an idea of the tremendous force of the plunges, and of the consequent terrible impetus given to all loose articles in the vessel.

It is then that the necessity of a cautious stowage, when there is a partial cargo, becomes obvious.
When lying-to (especially with a small bead sail), a vessel which is not properly modelled in the bows is frequently thrown upon her beam-ends; this occurring even every fifteen or twenty minutes upon an average, yet without any serious consequences resulting, provided there be a proper stowage.

If this, however, has not been strictly attended to, in the first of these heavy lurches the whole of the cargo tumbles over to the side of the vessel which lies upon the water, and, being thus prevented from regaining her equilibrium, as she would otherwise necessarily do, she is certain to fill in a few seconds and go down.
