Read it through once

The New York of Newland Archer's day was a small and slippery pyramid, in which, as yet, hardly a fissure had been made or a foothold gained. At its base was a firm foundation of what Mrs. Archer called "plain people"; an honourable but obscure majority of respectable families who (as in the case of the Spicers or the Leffertses or the Jacksons) had been raised above their level by marriage with one of the ruling clans. People, Mrs. Archer always said, were not as particular as they used to be; and with old Catherine Spicer ruling one end of Fifth Avenue, and Julius Beaufort the other, you couldn't expect the old traditions to last much longer.
