A second letter from a hawker and pedlar in the country, to a member of Parliament at London : in which the true yearly revenue and expence of a nation is fairly stated : the encouragement of frugality is recommended as the best method to increase the nation's revenue, and diminish its expence : all monopolies proved to be an encouragement to idleness and luxury : every restriction upon trade a step to monopoly : the extravagant profits taken formerly by the toy-shops : our improvement in that trade owing to the hawkers and pedlars : confederacies easily formed when any branch of trade in confined to a particular set of men : an account of the yearly expence of a London shop-keeper.
