But it was sore leaving.

People had been very kind; and were ready to be kinder still; while we, busy--perhaps too busy- -over our Natural History collections, had seen very little of our neighbours; had been able to accept very few of the invitations which were showered on us, and which would, I doubt not, have given us opportunities for liking the islanders still more than we liked them already.
Another cause made our leaving sore to us.

The hunger for travel had been aroused--above all for travel westward--and would not be satisfied.

Up the Orinoco we longed to go: but could not.

To La Guayra and Caraccas we longed to go: but dared not.
