What do "games" and "marrying-on" in the following mean?

The strong race is strong on these terms. The Saxons are the merchants of the world; now, for a thousand years, the leading race, and by nothing more than their quality of personal independence, and, in its special modification, pecuniary independence. No reliance for bread and games on the government, no clanship, no patriarchal style of living by the revenues of a chief, no marrying-on, -- no system of clientship suits them; but every man must pay his scot.

From Ralph Emerson's Wealth
