柯普生于一個(gè)特權(quán)家庭——他的父親是費(fèi)城一位有錢的商人——比馬什更富有冒險(xiǎn)精神,1876年夏天,在蒙大拿州,當(dāng)喬治·阿姆斯特朗·卡斯特和他的部隊(duì)在小比格角被消滅的時(shí)候,柯普還在附近找骨頭。有人提醒他,這時(shí)候來印第安人領(lǐng)地取寶,很可能是很不明智的。他想了片刻,決定繼續(xù)往下干。他的收獲太大了。有一次,他遇上了幾個(gè)疑心重重的克勞族印第安人,但他不停地取下和裝上他的假牙,贏得了他們的信任。
For a decade or so, Marsh and Cope's mutual dislike primarily took the form of quiet sniping,but in 1877 it erupted into grandiose dimensions. In that year a Colorado schoolteachernamed Arthur Lakes found bones near Morrison while out hiking with a friend. Recognizing thebones as coming from a "gigantic saurian," Lakes thoughtfully dispatched some samples to bothMarsh and Cope. A delighted Cope sent Lakes a hundred dollars for his trouble and asked himnot to tell anyone of his discovery, especially Marsh. Confused, Lakes now asked Marsh to passthe bones on to Cope. Marsh did so, but it was an affront that he would never forget.
有10年左右的時(shí)間,馬什和柯普之間的敵對關(guān)系主要以暗斗的形式出現(xiàn),但到了1877年,暗斗突然變成了大規(guī)模的沖突。那年,一位名叫阿瑟·萊克斯的科羅拉多州小學(xué)老師和他的一位朋友出門徒步旅行,在莫里森附近發(fā)現(xiàn)了幾根骨頭。萊克斯認(rèn)為那些骨頭屬于一條“巨蜥”;他想得很周到,把一些樣品寄給了馬什和柯普兩個(gè)人。柯普很高興,給萊克斯寄了100美元作為報(bào)酬,吩咐他不要把他的發(fā)現(xiàn)告訴任何人,尤其不要告訴馬什。萊克斯不大明白,便請馬什把骨頭轉(zhuǎn)交給柯普。馬什這么做了,但遭到了一番他永生難忘的羞辱。
