DANGEROUS VESSELS.

THE THEORY OF SUCTION. Th" gm tost liners of to-dfiv °eem to be a source of serious danger to smaller e s Is nm them m mi it ' ttr ins Th© suction taeorv was raised in the Hawice-Oivmpic case, and the Court tvns satisfied that the collision caused bv the great bulk of the Olympic drawing the warship oui of liei couise. In such a case tho larger ship takes water awa.v from the smaher, and the atier gets out ot control. Accoidmg I to an English expert, u ono ves.st-1 in i overtaking and passing anotnei, at thv noment wnen tnev are abreast and in closi proxunitv. tas effect of the disturbance created in ths v. utei is to produce a powerful lateral thrust upon th© bow of the vessel tiiat has been overtaken, tending to force the bow awav from the passing ship. As the taster vessel moves anead, and at about tne time when the bow of trie sloaei ship is mst aba it the centre cf tae taster, the conditions, are reversed, and there is set up a powerful force, tending to draw tne bow ot the ssoiier vessel towards tno passing ship. Lxiraordinarv proof of the power of such force was afforded bv the Titanic as sh<left t->onthampton.
