1:Mr Leach ’s compelling thesis is that 19th-century America provided a uniquely hospitable time and place for lovers, and especially collectors, of butterflies.2:Agricultural toil and westward expansion brought droves of ordinary people into intimate contact with vast expanses of pristine lands.[...]113:Most 19th-century Americans, Mr Leach writes—uncharitably but probably accurately—saw nature “as something to dig up or harvest from the earth or to be torn down and transformed into real estate or money”, and yet because there was so much untouched land, even the most rapacious miner or builder would in the course of his life come into contact with the natural world on a scale and in a way unknown to Americans today.

1:里奇先生的有趣命题是：19世纪的美国为蝴蝶爱好者，特别是收藏家提供了一个独一无二的热情好客的时代。2:农业耕作和西部扩张将大批的普通人与广袤无际的未开垦土地紧密联系在一起。[...]113:大多数19世纪的美国人，里奇先生写道，视自然为“可以从地下挖掘或从地上收割的，可以推倒盖房子或者卖钱的东西”，他的评语尽管尖刻，却也许十分精准。可是因为有如此之多未开垦的土地，即使是最贪婪的财主和建设者也会在他一生中与大自然发生联系,这种联系无论从规模上、在形式上， 都是如今的美国人无法想象的。
