about six in the evening
It owes its name to two rows of magnificent lime trees which form a charming promenade on each side of the broad carriage-way . Both sides abound in cafés and restaurants , whose crowds of customers , overflowing in summer on to the public road , cause a considerable amount of lively motion . This , however , never rises into noisy horse-play or clamour , for the Prussian prefers to amuse himself _ sub rosa _ , and keeps his gaiety within doors . But on June 7th , 1866 , as beautiful a day as Prussia can produce , Unter den Linden , at about six in the evening , presented a scene of most unusual commotion . The excitement was caused in the first place by the increasingly hostile attitude assumed by Prussia towards Austria , in refusing to allow the States of Holstein to proceed to the election of the Duke of Augustenburg , also by the general arming on all sides , by reports concerning the immediate calling up of the Landwehr and the dissolution of the Chamber , and finally by rumours of telegrams from France containing threats against Prussia , said to have been made by Louis Napoleon himself . It is necessary to travel in Prussia before one can in the least comprehend the sort of hatred therein cherished against the French . It is a species of monomania which distorts even the very clearest vision .
