Wagons with six mules should never, on a long journey over the prairies, be loaded with over 2000 pounds, unless grain is transported, when an additional thousand pounds may be taken, provided it is fed out daily to the team. When grass constitutes the only forage, 2000 pounds is deemed a sufficient load. I regard our government wagons as unnecessarily heavy for six mules. There is sufficient material in them to sustain a burden of 4000 pounds, but they are seldom loaded with more than half that weight. Every wagon should be furnished with substantial bows and double osnaburg covers, to protect its contents from the sun and weather. There has been much discussion regarding the relative merits of mules and oxen for prairie traveling, and the question is yet far from being settled. Upon good firm roads, in a populated country, where grain can be procured, I should unquestionably give the preference to mules, as they travel faster, and endure the heat of summer much better than oxen; and if the journey be not over 1000 miles, and the grass abundant, even without grain, I think mules would be preferable. But when the march is to extend 1500 or 2000 miles, or over a rough sandy or muddy road, I believe young oxen will endure better than mules; they will, if properly managed, keep in better condition, and perform the journey in an equally brief space of time. Besides, they are much more economical, a team of six mules costing six hundred dollars, while an eight-ox team only costs upon the frontier about two hundred dollars. Oxen are much less liable to be stampeded and driven off by Indians, and can be pursued and overtaken by horsemen; and, finally, they can, if necessary, be used for beef. In Africa oxen are used as saddle animals, and it is said that they perform good service in this way. This will probably be regarded by our people as a very undignified and singular method of locomotion, but, in the absence of any other means of transportation upon a long journey, a saddle-ox might be found serviceable.
