JANUARY 28TH.– There must soon be collisions in the West on a large scale; but the system of lying, in vogue among the Yankees, most effectually defeats all attempts at reliable computation of numbers. They say we have 150,000 men in Tennessee and Kentucky, whereas we have not 60,000. Their own numbers they represent to be not exceeding 50,000, but I suspect they have three times that number. The shadows of events are crowding thickly upon us, and the events will speak for themselves—and that speedily.
