Standing beneath this serene sky , overlooking these broad fields now reposing from the labors of the waning year , the mighty alleghenies dimly towering before us , the graves of our brethren beneath our feet , it is with hesitation that i raise my poor voice to break the eloquent silence of god and nature 站在静静的天空下，眺望广袤的田野? ?这些即将从逝去的岁月的劳作中得到休息的田野，看到隐隐约约耸立在我们面前的雄伟的阿勒格尼山脉，注视我们脚下同胞们的坟墓? ?这一切使我犹豫不决，不知该不该提高我那微不足道的嗓音，去打破上帝与自然界雄辩的沉默。

From the earliest english settlements at jamestown ( 1607 ) to the end of the 19th century , americans pushed constantly westward , first along the atlantic coast area , then the allegheny mountains , the mississippi river , the missouri river , the great plains , and finally the rocky mountains . at all times there were new frontiers to explore , new lands to conquer , and new dreams to pursue 就这样，从最早的英国定居点詹姆斯镇（ 1607年）到19世纪末，西行的浪潮不断推进：从大西洋海岸到阿勒格尼山脉、密西西比河、密苏里河、大平原直到落基山脉? ?在这推进的过程中，总有新的边疆去开拓，新的土地去征服，新的梦想去实现。
