23、们渴望着想试一试那种生活；我们不时还有一种希望，那就是，如果我们活在世上，品行挺好，上帝就会让我们当海盗。这些愿望，一个一个地都先后幻灭了；可是想当轮船上的水手这种志愿却始终保持下来了。 2.一艘简陋而外表华丽的定班轮船从圣路易斯开上来，另一艘从奇阿库克往下游开，每天都要来到这里一次。在这些大事出现之前，这一天使人充满了期望，显得光辉灿烂：这些大事过了之后，时光就变得死气沉沉，空空洞洞了。不仅孩子们有这种感觉，整个村镇都是一样。如今事隔多年，我仍旧能在心中描绘往日的情景，完全像当时那样：夏天早晨，白色的村镇在阳光中打盹；街上是空荡荡的，几乎一个人都没有：水街的杂货铺前面坐着一两个店员，他们把那
24、木条椅面的椅子翘起来，靠在墙上，下巴顶在胸前，帽子垂下遮着脸，打着瞌睡一他们身边有许多削木瓦的碎片，这就说明是什么事情把他们累坏了：一只母猪和一窝猪仔在人行道上闲荡着，痛痛快快地啃着西瓜皮和瓜子：两三个孤零零的小货物堆在“码头”上闲置着；石头铺的起卸码头的坡上有一堆“垫木”，镇上的流浪醉汉就在这木堆近旁酣睡着；码头上端有两三只平底木船，可是那拍打着这些船的小浪的柔和声响，却没有人倾听；伟大的密西西比河，壮丽、辉煌的密西西比河，让它那一英里宽的洪流滚滚奔腾下去，在阳光中放出闪光；河对岸的远处是茂密的森林；村镇上游的“地角”和下游的“地角”截断了河上景色的视线，把它变成了一片海面，而且这海面还是风
25、光明媚、沉寂而幽静的。随后有一股黑烟在远处的一个“地角”上空升腾起来；立刻就有一个以眼睛特别快、嗓子特别响出名的黑人运货马车夫高声喊道：“火轮船来了!”于是情况就变了!镇上那个醉汉翻身起来，那几个店员也醒了，随后就是运货马车的一阵狂暴的响声，每户人家和每个铺子里都涌出一股人流，转瞬之间，这个死气沉沉的村镇就热闹起来了、活动起来了。3.运货马车和大车，男子汉和孩子，都从四面八方连忙赶到一个大家聚集的中心地点码头上去。大家在那里集合之后，就把眼睛盯住那条开来的船，好像是注视他们第一次看到的一个稀奇东西一般。那条船也的确是相当美观。它又长又尖，收拾得又整洁、又漂亮。船上有两个高高的烟囱，顶上有些别致
26、的花样两个烟囱之间挂着一个金色的东西：还有一间别致的驾驶室，全是玻璃的，外表挺好看，其实并不值钱，驾凌后面的上层甲板之上；明轮罩也华丽非凡，那上面绘着图画，还在船名之上绘了一些金色的光带：锅炉甲板、顶层甲板和上层甲板周围都配置着干净的白栏杆；船头旗杆上神奇十足地飘着一面旗子：火炉的门是开着的，里面的火放射出熊熊的光来；上面的两层甲板黑压压地挤满了乘客；船长站在大钟旁边，神态镇静，挺有气派，他是大家羡慕的人物；大股大股的极黑的浓烟从烟囱里滚滚升腾起来一这是快到村镇之前，在火炉里添了一点多脂，特意造成的一种所费无几的威严气派；全体水手聚集在船头甲板上；宽阔的踏板在船头的舱门上面伸出船边很艮远，有一
27、个令人羡慕的水手神气十足地站在它的尽头，手里拿着一卷绳子：憋住的蒸汽从活嘴里进出尖叫的声音；船长举起手来，一口钟发出响声，机轮就停住了：然后机轮又向后转动，搅得河水冒出许多泡沫，于是轮船就不动了。接着是乱得一团糟，大家争先恐后，有的抢着上船，有的抢着上岸，有的要上货，有的要卸货，都在这同一时刻里抢着干。大副们为了催大家赶快，拼命地嚷，拼命地骂，那一阵叫骂声真是凶得要命!十分钟之后，轮船又开走了，船头旗杆上再也没有旗子，烟囱里再也不冒黑烟了。再过10分钟，这个小镇上又是死气沉沉，镇上那个醉汉又回到那堆垫木旁边去睡着了。4.我父亲是个治安法官，我以为他对一切的人都操着生杀之权，无论谁得罪了他，他都
28、可以处以绞刑。一般来说，这么大的威风原是足以使我满意的；然而想到轮船上当水手的愿望却是仍旧不断地闯进我脑子里来。起初我想当一个船舱里的茶房，为的是能够系着白色的腰围出来，在船边上抖一抖餐桌布，好让我所有的老玩伴们看得见；后来我又想到，还不如做那个子里拿着一卷绳子、站在踏板尽头的水手，因为他是特别惹人注目的。但是这些念头都只是白日梦而已要想把它们当成真有可能的事情来作打算，那却未免太高不可攀了。过了不久，我们那些孩子当中有一个跑掉了。他走了很久还没有；肖息。后来他终于以一艘轮船上的见习机匠或是“锤子”的身份突然出现了。这件事情全盘推翻了我所受的主日学校的一切的教训。那孩子向来是个有名的俗气鬼，而
29、我却恰恰相反：结果他居然高升到这种大出风头的地位，而我却无声无息，处境很惨。这家伙出头之后，气量一点也不大。他那艘轮船停靠在我们镇上的时候，他老足要故意找个锈了的铁栓来擦，而且他老是坐在靠岸的这边栏杆上面干，叫我们大家都能看得见他，又羡慕、又讨厌他。每逢他那艘轮船停得久一些的时候，他就一定回家来，穿着那满身油泥、黑得要命的衣服，到镇上各处出风头，叫每个人都不能不想起他是个轮船上的水乎：他谈起话未，还爱用轮船上各种各样的术语，好像他是说，惯了那一套，忘记别人听不懂似的。他竟至谈到一匹马也说什么“左舷”，说得那么若无其事、自自然然，简直使人，限之入骨。他常常谈到“圣路易斯”，仿佛他是那儿的老住户似的；还信口提起一些过去的事情，说他“顺着四马路走”呀，“路过场主饭店”呀，或者说有一次着了火，他在大密苏里号轮上亲手按了灭火机呀：然后他
