As this is nothing more than a blatant advert for them I hope Mainstreet Books from Amherst, MA in the States won't mind my pinching some of their scan and their transcription of this amazing letter. You can buy it here. And the description/letter goes like this:
It is not signed or have the name of the woman it was intended for on it, at the top it is dated, Jan 4th, 1877 and has Guilford before the date. One can assume it originated in Guilford CT as it was purchased in New England.
From the letter:
Guilford Jan 4th, 1877
The great love I have hitherto expressed for you is false, and I find my indifference towards you increases daily. The more I see of you, the more you appear in my eyes an object of contempt. I feel myself every way disposed and determined to hate you. Believe me, I never had an intention to offer you my hand. Our last conversation has left a tedious insipidity, which has no means given the most exalted idea of your character, your temper would make me extremely unhappy; and if we are united I shall experience nothing but the hatred of my parents, added to everlasting displeasure in living with you. I have indeed a heart to bestow, but I do not desire you to imagine it at your service. I could not give to any one more inconsistent and capricious than your self and less capable to do honor to my choice and my family. Yes Miss. I hope you will be persuaded that I speak sincerely and you will do me a favor to avoid me. I shall excuse you taking the trouble to answer this. Your letters are always full of impertinence and you have not even a showdown of wit and good sense. Adieu, Adieu believe me so averse to you that it is impossible for me even to be your affectionate friend and humble servant.
