But it is an error to suppose that our grave forefathers- though accustomed to speak and think of human existence as a state merely of trial and warfare, and though unfeignedly prepared to sacrifice goods and life at the behest of duty- made it a matter of conscience to reject such means of comfort, or even luxury, as lay fairly within their grasp.

我们严肃的先人们虽然习惯于港里这么说，而且心里也这么想，认为人类的生存无非是经受考验和斗争，并且诚心诚意地准备好一声令下即要牺牲自己的财富和生命，但如果认定他们从道义上会拒绝唾手可得的享乐或奢侈，那可就大错特错了。

In the model of intersection, the instruments had to be levelled and orientated relatively by aiming at mutually. Because levelling is manual and there is no mark of theodolite′s center which can be aimed at, the error of the common method of self-locating is too big to be allowed for precisional indus trial measuring.

Of the two great political parties which have divided the opinions and feelings of our country, the candid and the just will now admit that both have contributed splendid talents, spotless integrity, ardent patriotism, and disinterested sacrifices to the formation and administration of this Government, and that both have required a liberal indulgence for a portion of human infirmity and error. The revolutionary wars of Europe, commencing precisely at the moment when the Government of the United States first went into operation under this Constitution, excited a collision of sentiments and of sympathies which kindled all the passions and imbittered the conflict of parties till the nation was involved in war and the Union was shaken to its center. This time of trial embraced a period of five and twenty years, during which the policy of the Union in its relations with Europe constituted the principal basis of our political divisions and the most arduous part of the action of our Federal Government. With the catastrophe in which the wars of the French Revolution terminated, and our own subsequent peace with Great Britain, this baneful weed of party strife was uprooted.

至于导致我国在观点和情感上出现分歧的两大政党，率直公正的人现在都会承认，两党均为联邦政府的创建和运作贡献了杰出的才智、无暇地正直和热忱的爱国精神，并作出了无私的牺牲，当然两党都难免犯有人类的一部分毛病和错误，这也不足为怪，就在美国政府刚开始根据宪法运转之时，欧洲爆发了革命战争，由此激起国人互相对立的情绪和同情，导致全国群情激荡，党派冲突进而加剧，我国最终卷入了一场战争，联盟的支柱因而受到动摇，这一考验历时二十五年，在此期间，美国处理与欧洲关系的政策构成我们政治分歧的主要根源，也是联邦政府最为棘手的事情，随着法国革命战争在灾难中告终，我们随之幼鱼英国恢复和平，于是党派倾轧的这一毒草遂被连根拔除。
