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 head 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. It is not too much to say that at least one-half of the instances in which vessels have foundered in heavy gales at sea may be attributed to a shifting of cargo or of ballast. When a partial cargo of any kind is taken on board, the whole, after being first stowed as compactly as may be, should be covered with a layer of stout shifting-boards, extending completely across the vessel. Upon these boards strong temporary stanchions should be erected, reaching to the timbers above, and thus securing every thing in its place. In cargoes consisting of grain, or any similar matter, additional precautions are requisite. A hold filled entirely with grain upon leaving port will be found not more than three fourths full upon reaching its destination—this, too, although the freight, when measured bushel by bushel by the consignee, will overrun by a vast deal (on account of the swelling of the grain) the quantity consigned. This result is occasioned by settling during the voyage, and is the more perceptible in proportion to the roughness of the weather experienced. If grain loosely thrown in a vessel, then, is ever so well secured by shifting-boards and stanchions, it will be liable to shift in a long passage so greatly as to bring about the most distressing calamities. To prevent these, every method should be employed before leaving port to settle the cargo as much as possible; and for this there are many contrivances, among which may be mentioned the driving of wedges into the grain.
