The belt is full of dachi, i.e., summer villas, all now closed. […] Most of the dachi are small; but some large, sumptuous, and more securely fenced, a few with iron palisades to insure privacy. […] There are no roads in the environs of Odessa, except among the dachi by the shore.

This was a great rambling wooden house, fashioned, like most of the Muscovish dachi, or country houses, in the form of a square main building in the centre, flanked by a wing on each side which came forward in a semicircle, like a man’s outstretched arms, as though to embrace the approaching visitors.
