The moon was so bright i could a counted the drift logs that went a - slipping along , black and still , hundreds of yards out from shore
月亮通明，那往下漂过的圆木，我几乎能数得清清楚楚。离河岸上百码外，一片漆黑，一片寂静。
When it was dark i set by my camp fire smoking , and feeling pretty well satisfied ; but by and by it got sort of lonesome , and so i went and set on the bank and listened to the current swashing along , and counted the stars and drift logs and rafts that come down , and then went to bed ; there ain t no better way to put in time when you are lonesome ; you can t stay so , you soon get over it
我便在河岸上坐下，倾听着流水冲刷河岸声，数数天上的星星，数数从上游漂下来的木头和木筏子，然后去睡觉。在寂寞的时候，这是消磨时间最好的办法了。你不会老是这样的，你很快就会习惯的。
