WHEATLAND, near LANCASTER, June 24, 1852. MY DEAR SIR:— If it were possible for me to complain of your conduct, I should give you a good scolding for not performing your promise. We were all anxiously expecting you at Wheatland from day to day; and if you had informed me you could not come I certainly should have met you in Philadelphia. I was very anxious to see you, and now God only knows when we shall meet. Whilst life endures, however, gratitude for your friendship and support shall remain deeply engraved on my heart. I never felt any longing or anxious desire to be the President, and my disappointment did not cost me a single pang. My friends were faithful and true, and their efforts deserved if they could not command success. Personally, I am entirely satisfied with the result. When opportunity offers, I hope you will not fail to present my grateful acknowledgments to Generals Laferty and Polk, and to Messrs. Smith, Thomas and Shepherd, for their kind and valuable support in the hour of trial. It is vain to disguise the fact that Pennsylvania is, to say the least, a doubtful State. I much fear the result. If defeated, no blame shall attach to me. I will do my duty to the party and the country. Both personally and politically General Pierce and Colonel King are highly acceptable to myself. What an inconsistent race the Whigs are! They have now ostensibly abandoned their old principles, and placed themselves on the Democratic platform—Fugitive Slave Law and all. From this we may expect river and harbor improvements intended to catch the Southwest; and such a modification of a revenue tariff as they knew would exactly correspond with the wishes of the Democratic ironmasters of Pennsylvania. I, however, indulge the hope, nay, the belief, that Pierce and King can be elected without the vote of Pennsylvania.
