Passing from the prairie, we entered a broad belt of timber, and soon reached a fine stream. We drew rein at a farmhouse on the top of the river-bank, where we found a pleasant Union family. The farmer came out, and, thinking Colonel Eaton was the General, offered him two superb apples, large enough for foot-balls. He was disappointed to find his mistake, and to be compelled to withdraw the proffered gift. Sigel encamped here last night;, and the _débris_ of his camp-fires checker the hill-side and the flats along the margin of the creek. After waiting an hour, the General not coming up, Colonel Eaton and myself set out alone over a road which was crowded with Sigel's wagons. Everything bears witness to the extraordinary energy and efficiency of that officer. This morning he started before day, and he will be in Springfield by noon to-morrow. His train is made up of materials which would drive most generals to despair. There are mule-teams, and ox-teams, and in some cases horses, mules, and oxen hitched together. There are army-wagons, box-wagons, lumber-wagons, hay-racks, buggies, carriages,--in fact, every kind of animal and every description of vehicle which could be found in the country. Most of our division-commanders would have refused to leave camp with such a train; but Sigel has made it answer his purpose, and here he is, fifty miles in advance of any other officer, tearing after Price. We were jogging painfully over the incumbered road, and through clouds of dust, when an officer rode up in great haste, and asked for Dr. C., who was needed at the camp of the Guards. By reason of the broken order in which the staff rode to-day, he could not be found. For two mortal hours unlucky aides-de-camp dashed to the front and the rear, and scoured the country for five miles upon the flanks, visiting the farm-houses in search of the missing surgeon. At last he was found, and hurried on to the relief of the Guard. At this moment the General came up, and, to our astonishment, Zagonyi was riding beside him, bearing upon his trim person no mark of yesterday's fatigue and danger. The Major fell behind, and rode into Bolivar with me. On the way we met Lieutenant Maythenyi of the Guard. Our camp is on the farm of a member of the State legislature who is now serving under Price. His white cottage and well-ordered farm-buildings are surrounded by rich meadows, bearing frequent groups of noble trees; the fences are in good condition, and the whole place wears an air of thrift and prosperity which must be foreign to Missouri even in her best estate.
