The botanical garden of St. Petersburg, like all the rest of the
institutions, is of gigantic dimensions. It contains sixty-five acres: a
parallelogram formed by three parallel lines of hot-houses and
conservatories, united at the extremities by covered corridors,
constitutes the grand feature of this establishment. The south line
contains green-house plants in the centre, and hot-house plants at each
end; the middle line has hot-house plants only, and the north line is
filled with green-house plants. The connecting corridors are two hundred
and forty-five feet. The north and south line contain respectively five
different compartments of one hundred toises each, that is to say, they
are together six thousand feet. The middle line has seven compartments,
that is, three thousand more, making in the whole length nine thousand
feet!--_Granville's Travels_.
