'We are to make it a regular thing,' Nancy explained, 'and who knows, Ally, but that it may become one of the classic correspondences in our language? We are to have borrowed names chosen by him. How I love this fancy of Arcadian names in such a commerce; it gives the last delightful touch of romance. He is to be "Sylvander," and I "Clarinda." Now is not "Clarinda" a pretty name, Ally?

'Oh, how could she do it?' wailed Alison, alluding to her less-fastidious sister. 'Kate, too, the bonniest of us all!'
