WASHINGTON, June 21.
Col. Kane arrived here last night, and brings despatches from Gov. Cummings whom he left at camp Scott, May 16th. They were delivered to the President.
Their purport has not officially transpired.
It is understood that Col. Kane denies the proof of the Telegraphic announcement from Boonville, intimating that the army would move on the arrival of the Peace Commissioners, when in fact Gov. C. had requested it to remain where it is until orders are received from Washington.
