Among other sights are immense droves of cattle with their drivers, passing through the streets of the city. Some of the men have a way of leading the cattle by a peculiar call, a wild, pensive hoot, quite musical, prolong'd, indescribable, sounding something between the cooing of a pigeon and the hoot of an owl. I like to stand and look at the sight of one of these immense droves--a little way off--(as the dust is great.) There are always men on horseback, cracking their whips and shouting--the cattle low--some obstinate ox or steer attempts to escape--then a lively scene--the mounted men, always excellent riders and on good horses, dash after the recusant, and wheel and turn--a dozen mounted drovers, their great slouch'd, broad-brim'd hats, very picturesque--another dozen on foot--everybody cover'd with dust--long goads in their hands--an immense drove of perhaps 1000 cattle--the shouting, hooting, movement, &c. HOSPITAL PERPLEXITY To add to other troubles, amid the confusion of this great army of sick, it is almost impossible for a stranger to find any friend or relative, unless he has the patient's specific address to start upon. Besides the directory printed in the newspapers here, there are one or two general directories of the hospitals kept at provost's head-quarters, but they are nothing like complete; they are never up to date, and, as things are, with the daily streams of coming and going and changing, cannot be. I have known cases, for instance such as a farmer coming here from northern New York to find a wounded brother, faithfully hunting round for a week, and then compell'd to leave and go home without getting any trace of him. When he got home he found a letter from the brother giving the right address. DOWN AT THE FRONT
