It seems to me that the last two lines are in the method of (sometimes) repeating the last strain in a song to end it, but in this case the words are changed to rather sum up what happens...she finally gave her heart to the man and was thankful she did spend the time "on Todd's sweet rural shade"...but it will be nice to confirm if the lyrics are complete.
Thanks Ian M, for mentioning "Down by the Sally Gardens" as the melody...it was bugging me as to what song the melody reminded me of. I agree that it is Sally Gardens, but with some variations in certain areas...will have to compare the melody lines very closely and will try to submit my findings. It won't be for a couple weeks since I'll be going out of town to visit family.
Haven't heard "Dobbin's Flowery Vale"..will have to see if I can locate a copy.
