troi_ of three
dollars per barrel is estimated to yield fifty thousand dollars,
or two thousand dollars less than soda-water. Seventy-five thousand
dollars is the aggregate fee of the restaurants. Of these last-named
establishments, the French have two. The historic sign of the Trois
Freres Provencaux is assumed by a vast edifice in one of the most
conspicuous parts of the enclosure, sandwiched between the Press and
the Government. The "Sudreau" affects the fine arts and cultivates
with like intimacy the society of Memorial Hall. The German refectory,
Lauber's, a solid, beery sort of building, shows a fine bucolic
sense by choosing a hermitage in the grove between Agricultural
and Horticultural Halls. A number of others, of greater or less
pretensions, will enable the visitor to exclaim, with more or less
truth, toward the dusty evening, "Fate cannot harm me: I have dined
to-day."

"Dusty," did we say? The ceaseless sob of engines that rob the

asphaltum, gravel and greensward demands recantation of the word.
Everything has been foreseen and considered, even the dust of the

several days' holiday, and keep all fresh and dewy as the dawn.

would seem to meet this want. The reader of _Dombey and Son_ will
recollect the pictorial effect, in print and etching, of the popping
up of the head of the propellent force when Mrs. S. called a halt, and
its sudden disappearance on her directing a resumption of movement.
The bobbing up and down of four hundred and fifty heads, like so
many seals, will impart a unique aspect to the vista from one of the
interior galleries of the great hall. The stipulated tax of forty
dollars on each of these vehicles will necessitate a tolerably active
undulation of polls if
