These words are frequently introduced in policies of insurance, giving the party insured the right to stop and stay at certain designated points in the course of the voyage. A vessel which has the power to touch and stay at a place in the course of the voyage, must confine herself strictly to the terms of the liberty so given; for any attempt to trade at such a port during such a stay, as by shipping or landing goods, will amount to a species of deviation which will discharge the underwriters, unless the ship have also liberty to trade, as well as to touch and stay at such a place.
