PETERSBURG; THE WAR MADE it Petrograd; the revolution made it Leningrad. It is a city of stone, and those living in it think not of stone brought upon a green earth and piled block on block to raise a city, but of one huge rock carved into streets, bridges, houses, and earth brought in handfuls, scattered, ground into the stone to remind them of that which lies beyond the city. Its trees are rare strangers, sickly foreigners in a climate of granite, forlorn and superfluous. Its parks are reluctant concessions. In spring, a rare dandelion sticks a bright yellow head through the stones of its embankments, and men smile at it incredulously and condescendingly as at an impudent child. Its spring does not rise from the soil; its first violets, and very red tulips, and very blue hyacinths come in the hands of men, on street corners. Petrograd was not born; it was created. The will of a man raised it where men did not choose to settle. An implacable emperor commanded into being the city and the ground under the city.
