“I waited on Mr. Peters, as you desired me to do. He treated me kindly, and made an offer of doing me some services; for which I am greatly obliged to him. He likewise paid me for my attendance at New-Castle, and much more generously than I expected;—though I found it a very laborious affair; being obliged, singly, to go through a number of tedious and intricate calculations.” It appears that about this time, Mr. Rittenhouse’s friends had some beneficial object in view for him; perhaps some official situation, which they conceived to be adapted to the nature of his pursuits, and such as might more permanently promote his interests. But whatever that object may have been, he seems to have hesitated about it. If it were a public appointment of a permanent kind, it would probably have required his removal to the city,—a measure which he did not contemplate at that time; and he might, besides, have been disinclined to undertake any official duties, which would be likely to occupy the greater part of his time. He expressed himself thus to Mr. Barton, on the subject, in the letter just quoted:—“I am greatly obliged to you, my dear brother, for pointing out any prospect of advantage to me: I shall consider the matter you mention in your last, and let you know my opinion. The objections you have so well answered, are those which would most readily occur to me. Considering the crazy state of my constitution, a retired life would certainly suit me best. Since death, to use John Bunyan’s[102] phrase, does usually knock at my door once a day, would it not be a folly for me to take up the load of any public business?” Footnote 102: ----- The writer of these memoirs well remembers to have heard Mr. Rittenhouse, when fully matured in years, speak of the pleasure he derived from the reading of John Bunyan’s _Pilgrim’s Progress_, while a youth. It is, certainly, no faint compliment to the “well-told tale” of that “ingenious dreamer,” that it engaged the attention of David Rittenhouse, even at a very early period of his life: and that compliment is greatly enhanced by the following beautiful invocation, addressed to the long-since departed spirit of the humble, yet persecuted, the pious, yet fanciful Bunyan, by the amiable Cowper:—
