Joe Twichell wrote to Sam.

I have been thinking of you all the morning. This is one of  those golden, perfect autumn days when ones desire to off somewhere among  trees, mounts to a passion… Now, Mark, let’s make a vow, that when we are once  more together we will use these heavenly days as they were meant to be used and  as we shall wish we had when we come to look back on life [MTP]. Note: there is  much more and more depth to this letter, but space here does not allow it all.
