The first thing to see, looking away over the water, was a kind of dull line -- that was the woods on t'other side; you couldn't make nothing else out; then a pale place in the sky; then more paleness spreading around; then the river softened up away off, and warn't black any more, but gray; you could see little dark spots drifting along ever so far away -- trading scows, and such things; and long black streaks -- rafts; sometimes you could hear a sweep screaking; or jumbled up voices, it was so still, and sounds come so far; and by and by you could see a streak on the water which you know by the look of the streak that there's a snag there in a swift current which breaks on it and makes that streak look that way; and you see the mist curl up off of the water, and the east reddens up, and the river, and you make out a log-cabin in the edge of the woods, away on the bank on t'other side of the river, being a woodyard, likely, and piled by them cheats so you can throw a dog through it anywheres; then the nice breeze springs up, and comes fanning you from over there, so cool and fresh and sweet to smell on account of the woods and the flowers; but sometimes not that way, because they've left dead fish laying around, gars and such, and they do get pretty rank; and next you've got the full day, and everything smiling in the sun, and the song-birds just going it!

往 水面上望去，首先看到的是灰蒙蒙的一条线——那是河对岸的树林子——别的便什么也看不清——接着是天空中有一点儿鱼肚白；然后鱼肚白多了些，逐渐朝四周散开去；接下来，远处河水的颜色淡了些，不是那么黑了，而是灰灰的了。更远处，可以看到小小的黑点子在漂过来——那是些载货的驳船之类。还有黑黑的一长条——那是木筏子。有时能听到长桨吱吱地响，或者一些杂音。四周这么寂静，声音又来自很远的远方。过了一会儿，你看到一道水纹。凭了水纹的模样，你知道那里有一块礁石，急流朝着它冲过去，流水飞溅，成了这个模样。你看到，雾气袅袅上升，离开水面，东方红了起来，河面红了起来。你可以看到对岸河边树林子边上一处原木搭成的小屋，那可能是一个木材场，在那里堆着的一堆堆木材，中间却是空的，容得狗钻来钻去，为了能叫人家上当①。然后微风轻拂，从河上一阵阵吹来，那么凉凉的，那么清新，闻起来那么甜美，这是全凭了那些树林子和那些鲜花的缘故。可有时候也并非全是如此美妙。
