222. The Navigation Act and the Colonies. As the colonies grew, the
Navigation Act supplied a suitable mechanism for controlling their traffic,

hemp and naval stores. Increased attention was devoted to improving the
prospects of seamen in the Navy and Merchant Service, and to affording
better facilities for protecting ships on our coasts, by erecting light-houses

224. Marine Insurance. The practice of marine insurance had been
organised under Elizabeth, and was developed by the establishment of the
London Assurance and Royal Exchange Assurance, as well as by the con-
centration at Lloyd's Coffee House of under-writers, who refused to engage
