A cold, drizzling rain continued to descend for several days, and our camp became a fair specimen of "Virginia mud." I began to feel the effects of the miasma which came floating on every breeze from the adjacent swamps and marshes, and fever and ague became my daily companions for a time. As I sat in my tent, roasting or shivering as the case might be, I took a strange pleasure in watching the long trains of six mule teams which were constantly passing and repassing within a few rods of my tent. As "Miss Periwinkle" remarks, there are several classes of mules. "The coquettish mule has small feet, a nicely trimmed tail, perked up ears, and seems much given to little tosses of the head, affected skips and prances, and, if he wears bells or streamers, puts on as many airs as any belle. The moral mule is a stout, hardworking creature, always tugging with all his might, often pulling away after the rest have stopped, laboring under the conscientious delusion that food for the entire army depends upon his individual exertions. The histrionic mule is a melo-dramatic sort of quadruped, prone to startle humanity by erratic leaps and wild plunges, much shaking of the stubborn head and lashing of his vicious heels; now and then falling flat, and apparently dying _a la_ Forrest, a gasp, a groan, a shudder, etc., till the street is blocked up, the drivers all swearing like so many demons, and the chief actor's circulation becomes decidedly quickened by every variety of kick, cuff and jerk imaginable. When the last breath seems to have gone with the last kick, and the harness has been taken off, then a sudden resurrection takes place. He springs to his feet, and proceeds to give himself two or three comfortable shakes, and if ever mule laughed in scornful triumph it is he, and as he calmly surveys the excited crowd, seems to say: 'A hit! a decided hit!' For once the most stupid of all animals has outwitted more than a dozen of the lords of creation. The pathetic mule is, perhaps, the most interesting of all; for although he always seems to be the smallest, thinnest, and weakest of the six, yet, in addition to his equal portion of the heavy load, he carries on his back a great postillion, with tremendous boots, long tailed coat, and heavy whip. This poor creature struggles feebly along, head down, coat muddy and rough, eye spiritless and sad, and his whole appearance a perfect picture of meek misery, fit to touch a heart of stone. Then there is another class of mules which always have a jolly, cheer-up sort of look about them--they take everything good naturedly, from cudgeling to carressing, and march along with a roguish twinkle in their eye which is very interesting."
