Thanks, Hugh. I’ve updated the title (I had the date for the correct one, at least, but I can understand the confusion). Oddly enough, in the volume at the link you provide, it does have that quotation in the section labeled “Introduction” (https://books.google.com/books?id=DTKL1qAIKbQC&lpg=PA542&pg=PA546#v=onepage&q=%22tender%20years%22&f=false), but in the Google Book I found that is strictly the History (linked to as “Source”), it shows up in Letter 1 as you suggest, and given the form of address, I’m going to update the title to reflect that as well.
