eight
o'clock
At four o'clock , the ladies and children left the king , as it was his custom to sleep at this hour . At six Clery and Louis entered the apartment , and Clery gave the boy lessons in writing , and copied , at the king 's desire , passages from the works of Montesquieu and others , for the use of the Dauphin . Then Clery took Louis to his aunt 's room , where they played at ball , and battledore and shuttlecock , till Louis 's supper-time , at eight o'clock . Meanwhile the queen and the Princess Elizabeth read aloud , till eight o'clock , when they went to Louis , to sit beside him while he had his supper . Then the king amused the children with riddles , which he had found in a collection of old newspapers . All kindly exerted themselves to send Louis cheerful to bed . He was too young , they thought , to lie down with so sad a heart as they each had every night in their prison .
