      DELHI, Delaware Co., July 8, 1856.

   We have just had a glorious ratification meeting of the Republicans of Delaware County. The meeting was largely attended, and ended, after speeches, dinner, and toasts with an unqualified approval of the men who are to lead the Republican Party to victory and the Nation to Liberty next November.

   The County and State are for JOHN C. FREMONT and WM. L. DAYTON!

   Three years ago the Administration had it all their own way in Iowa, and doubly so in Delaware County — while in these parts to speak of being an opponent of Slavery smelled strongly of tar and feathers, to say the least.

   But now, thanks to the infamous Kansas-Nebraska outrage, the people have arisen in their might and put from them "the unclean beast," and we are thoroughly rid of every official favoring the murderous policy of this Administration, except the Postmasters; and they will be ousted in March next if freemen will do their duty. J.T.C.

       GRINNELL, Iowa, July 2, 1856.

   Iowa is just now all awake politically. The nomination of Fremont is by far the most popular that could have been made. Democracy with its apostate leaders has lost its power of enchantment and it is a low estimate that ten thousand voters will leave the ranks at this election for True Democracy.

   A large and enthusiastic convention is held here to-day, embracing a Senatorial District—the Counties of Jasper, Poweshiek, Marshall and Tama. All the 34 delegates voted on the first ballot for J.B. Grinnell for Senator, from your city where he was a minister. His friends claim for him not less than 500 majority—perhaps 1,000—the Convention being composed of at least one-third of former Pierce men.

   Mr. Edmundson of Jasper County was also by acclamation nominated for Representative from this District—a much respected citizen, whose election is next to sure by a majority of hundreds.

   Sam A. Rice, candidate for Attorney-General, and Mr. Foster of Poweshiek, and Jackson of Tama, (late of New-York,) made eloquent and elevated speeches.

   Col. Curtis of Keokuk, the Republican candidate for Congress in this District, speaks here to-morrow. He is a native of the South, but a host in the cause, speaking twice each work-day until the day of the election. He has Messrs. Hall, Knapp and Clogget (the latter a renegade Whig, I am told.) on his track, but they waste their gas. It is too late.

   Violence in Washington and Kansas have stirred the masses. To-day we sent eight good fellows, well fitted out by the citizens here, to join Col. Lane with some 150, all peaceable men, on their way to Kansas. Let the East do her duty for Freedom, and the West will not hold back. Some 30 WEEKLY TRIBUNES have just been ordered to this place, and for us "there shall be light."

[Note: John C. Frémont was the Republican nominee for President in the 1856 election, but lost to James Buchanan in a three-way vote.]
