three little corners in the world that have not felt the effect of such
removals. The Romans by this means erected their colonies; for,
perceiving their city to grow immeasurably populous, they eased it of the
most unnecessary people, and sent them to inhabit and cultivate the lands
conquered by them; sometimes also they purposely maintained wars with
some of their enemies, not only to keep their own men in action, for fear
lest idleness, the mother of corruption, should bring upon them some
worse inconvenience:

"Et patimur longae pacis mala; saevior armis
Luxuria incumbit."

["And we suffer the ills of a long peace; luxury is more pernicious

In the treaty of Bretigny, Edward III., king of England, would not, in
the general peace he then made with our king, comprehend the controversy
about the Duchy of Brittany, that he might have a place wherein to
discharge himself of his soldiers, and that the vast number of English he
had brought over to serve him in his expedition here might not return
back into England. And this also was one reason why our King Philip
consented to send his son John upon a foreign expedition, that he might
take along with him a great number of hot young men who were then in his
pay.
