Read it through once

In a minor tournament I won the prize, which was a Waterbury watch. I put it in my trunk. In Pretoria, South Africa, nine months afterward, my proper watch broke down and I took the Waterbury out, wound it, set it by the great clock on the Parliament House (8.05), then went back to my room and went to bed, tired from a long railway journey. The parliamentary clock had a peculiarity which I was not aware of at the time —a peculiarity which exists in no other clock, and would not exist in that one if it had been made by a sane person; on the half-hour it strikes the succeeding hour, then strikes the hour again, at the proper time. I lay reading and smoking awhile; then, when I could hold my eyes open no longer and was about to put out the light, the great clock began to boom, and I counted ten. I reached for the Waterbury to see how it was getting along. It was marking 9.30. It seemed rather poor speed for a three-dollar watch, but I supposed that the climate was affecting it. I shoved it half an hour ahead; and took to my book and waited to see what would happen. At 10 the great clock struck ten again. I looked—the Waterbury was marking half-past 10. This was too much speed for the money, and it troubled me. I pushed the hands back a half hour, and waited once more; I had to, for I was vexed and restless now, and my sleepiness was gone. By and by the great clock struck 11. The Waterbury was marking 10.30. I pushed it ahead half an hour, with some show of temper. By and by the great clock struck 11 again. The Waterbury showed up 11.30, now, and I beat her brains out against the bedstead. I was sorry next day, when I found out.
