No one walking on the Champs Elysees or on the Boulevards to-day would suppose that 300,000 Prussians are within a few miles of the city, and intend to besiege it. Happy, said Laurence Sterne, in his "Sentimental Journey," the nation which can once a week forget its cares. The French have not changed since then. To-day is a fete day, and as a fete day it must be kept. Every one seems to have forgotten the existence of the Prussians. The Cafes are crowded by a gay crowd. On the Boulevard, Monsieur and Madame walk quietly along with their children. In the Champs Elysees honest mechanics and bourgeois are basking in the sun, and nurserymaids are flirting with soldiers. There is even a lull in the universal drilling. The regiments of Nationaux and Mobiles carry large branches of trees stuck into the ends of their muskets. Round the statue of Strasburg there is the usual crowd, and speculators are driving a brisk trade in portraits of General Uhrich. "Here, citizens," cries one, "is the portrait of the heroic defender of Strasburg, only one sou--it cost me two--I only wish that I were rich enough to give it away." "Listen, citizens," cries another, "whilst I declaim the poem of a lady who has escaped from Strasburg. To those who, after hearing it, may wish to read it to their families, I will give it as a favour for two sous." I only saw one disturbance. As I passed by the Rond Point, a very tall woman was mobbed, because it was thought that she might be a Uhlan in disguise. But it was regarded more as a joke than anything serious. So bent on being happy was every one that I really believe that a Uhlan in the midst of them would not have disturbed their equanimity. "Come what may, to-day we will be merry," seemed to be the feeling; "let us leave care to the morrow, and make the most of what may be our last fete day."
