Sometime I contriv'd to dig a Hole under the Place where they made their Fire, and put in five or six Pound of Gun-powder, which when they kindled their Fire, would consequently take Fire, and blow up all that was near it; but as in the first Place I should be very loth to wast so much Powder upon them, my Store being now within the Quantity of one Barrel; so neither could I be sure of its going off' at any certain Time, when it might surprise them, and at best, that it would do little more than just blow the Fire about their Ears and fright them, but not sufficient to make them forsake the Place; so I laid it aside, and then propos'd, that I would place my self in Ambush, in some convenient Place, with my three Guns, all double loaded; and in the middle of their bloody Ceremony, let fly at them, when I should be sure to kill or wound perhaps two or three at every shoot; and then falling in upon them with my three Pistols, and my Sword, I made no doubt, but that if there was twenty I should kill them all: This Fancy pleas'd my Thoughts for some Weeks, and I was so full of it, that I often dream'd of it; and sometimes that I was just going to let fly at them in my Sleep.

就我目前的境况而言，我其实不缺多少东西。可是，我总感到，由于受到那些野蛮的食人生番的惊吓，因而时时为自己的安全而担惊受怕。以往，为使自己的生活过得舒服，我充分发挥了创造发明的才能，但现在就无法充分发挥了。我本来有一个煞费苦心的计划，想试验一下能否把大麦制成麦芽，再用麦芽来酿起酒。现在，这一计划也放弃了。当然，这实在也是一个荒唐的念头，连我自己也经常责备自己把事情想得太简单了。因为我不久就看出，许多酿造啤酒必不可少的材料我都没有，也无法自己制造。首先，没有啤酒桶。前面说过，我曾尝试做木桶，但怎么也做不好。我曾花了许多天、甚至许多星期、许多个月，结果还是没有成功。其次，没有啤酒花使酒经久不坏，没有酵母发酵，没有铜锅铜罐煮沸。可是，尽管如此，我还是坚信，要是没有对食人生番的惊惧和恐怖，我早就可能着手去做了，甚至也许已做成功了。

Sometimes I thought if digging a hole under the place where theymade their fire, and putting in five or six pounds of gunpowder,which, when they kindled their fire, would consequently take fire,and blow up all that was near it: but as, in the first place, Ishould be unwilling to waste so much powder upon them, my storebeing now within the quantity of one barrel, so neither could I besure of its going off at any certain time, when it might surprisethem; and, at best, that it would do little more than just blow thefire about their ears and fright them, but not sufficient to makethem forsake the place: so I laid it aside; and then proposed thatI would place myself in ambush in some convenient place, with mythree guns all double-loaded, and in the middle of their bloodyceremony let fly at them, when I should be sure to kill or woundperhaps two or three at every shot; and then falling in upon themwith my three pistols and my sword, I made no doubt but that, ifthere were twenty, I should kill them all.

这时，我已怒不可遏了，但还是强压心头的怒火，往回走了二十多步，来到一片矮树丛后面。靠着这片矮树丛的掩护，我一直走到那棵大树背后。那里有一片小小的高地，离那些野人大约有八十码远。我走上高地，把他们的一举一动看得清清楚楚。事情已发展到万分紧急的关头了，因为我看到有十九个野人挤在一起坐在地上，他们派出另外两个野人去宰杀那可怜的基督徒。看来，他们是要肢解他，一条胳膊一条腿地拿到火上去烤。我看到那两个野人这时已弯下腰，解着那白人脚上绑的东西。我转头对星期五说：&听我的命令行动。&星期五说他一定照办。我就说：&好吧，星期五，你看我怎么办就怎么办，不要误事。&于是，我把一支短枪和一支乌枪放在地下，星期五也跟着把他的一支鸟枪和一支短枪放在地下。我用剩下的一支短枪向那些野人瞄准，并叫星期五也用枪向他们瞄准。然后，我问星期五是否准备好了，他说：&好了。&

There is nothing glamorous in this simple town But there's this special flower that can only bloom right here And all the heavy burdens in our heart, Get carried away The wind can smooth the wrinkles of the past Like a dazzling reflection in the sky I hear the distant calling of the ancient ripples of the sea And I realise that your laughter reminds me Of the soothing sound of the gentle ocean And your heart can't cover up the look of loneliness You don't have to reveal it to me But anytime you need it These faces so familiar in your heart Wait for you to reach to their hands I want to know if that place That I've been once before Hasn't ever changed And remains the place that always will be there for me Till the last goodbye ill cherish it And I can't stop looking back to see That you're smiling waving back at me Gonna bite my lips not to cry And I'm trying to fight this feeling But the tears may get so hard to see Ill be waiting for the day We can reunite again Where the flowers bloom For Jus me and you There is something that the shadows can't explain Something so simple and so obvious, that we forget Behind the cloudy surface of it all, if we look up above We'll see the sun shine illuminate everything we see All the past and present faces here are all to stay Each prayer wishes new memories Im proud to have it all These memories alive inside my heart Blossoming vividly one by one After the rain the roads are muddy and there's puddles everywhere And we clearly see all the footsteps in this journey thru this life we lead And I pray these tears can find a way and breathe life back into the day When the weltered petals in my heart once again blossoming And ill whisper to the ocean breeze and my wish will soar above the seas And a rainbow in the sky will appear for you and i Glistening in the sun, shine for everyone Hey, the only place where the flowers bloom The only place where this wind can blow The only place you can hear this song The only place you can see these sign Hey, the only place where the flowers bloom The only place where this wind can blow I want to know if that place That I've been once before Hasn't ever changed And remains the place that always will be there for me And ill try to fight this feeling But the tears may get so hard to see Ill be waiting for the day We can reunite again After the rain the roads are muddy and there's puddles everywhere And we clearly see the footsteps in this journey thru this life we lead I try to fight this loneliness But the tears may get so hard to see Even thru the scars and memories I won't forget you and me So radiantly shining thru The horizon as it rises high And the wind carries it star beneath the memories Ooh still im waiting for you
