six o'clock
My uncle took my father 's arm and disappeared into the study ; and we two boys were left to take care of each other until dinner-time . I proposed going round the garden , and Frisk being of the party , proceeded to show off his accomplishments . This led to an animated description of my cousin 's dog , Cæsar , and a comparison of the ways and habits of Cæsar the Big with those of Frisk the Little , on the strength of which we became very intimate . Afterwards we returned to the house , and having shown Aleck his room , I took him into mine , where we were found seated on the floor surrounded by `` my things , '' which I had been exhibiting in detail to my cousin , when nurse came , a little before six o'clock , to see that we were ready for dinner . `` Aleck , tell me one thing , '' I had just said to my cousin ; `` are they really your knees or leather ? '' Aleck stared , `` Leather ! why , of course not ; what made you think such an odd question ? ''
