222. The Navigation Act and the Colonies. As the colonies grew, the
Navigation Act supplied a suitable mechanism for controlling their traffic,
so as to promote British industry, and to render England a staple for
enumerated commodities. Great attention was given to the West India
Islands, as a depôt for Mexican trade, and in connection with the slave trade.
In this England was chiefly interested, as it helped to secure the economic
dependence of the plantations, and the African market for manufactures.
The traffic had disastrous results on the negroes, and was of doubtful
economic advantage; but the treatment of slaves in the West Indies was
improved by astricting them to particular estates. The Navigation Acts
were injurious to the islands, but helped to stimulate shipbuilding in New
England; while British attempts to cut off Colonial intercourse with the
French engaged in the Newfoundland fisheries, and with the French West-
India Islands, gave rise to considerable grievance.

223. Shipbuilding, Naval Stores, and Seamanship. While providing
for the employment of shipping, the statesmen of the day maintained their
care for fishing for herring and cod, and for whaling. Bounties were given
on shipbuilding, and the colonists were encouraged by bounties to supply
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
and improving harbours and charts.
