The other is that the charge for cabanas and parasols, though modest from an American point of view, still is a little high for many Athenians.

Master Gorton, having foully abused high and low at Aquidneck is now bewitching and bemaddening poor Providence, both with his unclean and foul censures of all the ministers of this country ( for which myself have in Christ's name withstood him ), and also denying all visible and external ordinances in depth of Familism: almost all suck in his poison, as at first they did at Aquidneck.

Milton's name being fourth is neither too high nor too low to be assigned to the arbitrary action of vice-chancellor, proctor, master, or other mighty hand.

The NATO Council is available as an executive agency, the Standing Group as a high military authority.

Around that statue in the green park where children play and lovers walk in twos and there is a glowing view of the whole city, in that park are the rows of marble busts of Garibaldi's fallen men, the ones who one day rushed out of the Porta San Pancrazio and, under fire all the way, up the long, straight narrow lane to take, then lose the high ground of the Villa Doria Pamphili.

the Army, Navy and Air Force, among others, may question Secretary Freeman's claim that the high estate of United States agriculture is the `` strongest deterrent '' to the spread of communism.

He is basing his guess on new government statistics that show business has broadened its stride -- a new record high in personal income, an increase in housing starts, a spurt in retail sales and a gain in orders for durable goods.
