 During the period between 1866 and 1867 , Cope went on trips to western parts of the country . He related to his father his scientific experiences ; to his daughter he sent descriptions of animal life as part of her education . Cope found educating his students at Haverford " a pleasure " , but wrote to his father that he " could not get any work done . " He resigned from his position at Haverford and moved his family to Haddonfield , in part to be closer to the fossil beds of western New Jersey . Due to the time @-@ consuming nature of his Haverford position , Cope had not had time to attend to his farm and had let it out to others , but eventually found he was in need of more money to fuel his scientific habits . Pleading with his father for money to pursue his career , he finally sold the farm in 1869 . Alfred apparently did not press his son to continue farming , and Edward focused on his scientific career . He continued his continental travels , including trips to Virginia , Tennessee , and North Carolina . He visited caves across the region . He stopped these cave explorations after an 1871 trip to the Wyandotte Caves in Indiana , but remained interested in the subject . Cope had visited Haddonfield many times in the 1860s , paying periodic visits to the marl pits . The fossils he found in these pits became the focus of several papers , including a description in 1868 of Elasmosaurus <unk> and Laelaps . Marsh accompanied him on one of these excursions . Cope 's proximity to the beds after moving to Haddonfield made more frequent trips possible . The Copes lived comfortably in a frame house backed by an apple orchard . Two maids tended the estate , which entertained a number of guests . Cope 's only concern was for more money to spend on his scientific work .
