Unless a systematic organization be adopted, it is impossible for a party of any magnitude to travel in company for any great length of time, and for all the members to agree upon the same arrangements in marching, camping, etc. I have several times observed, where this has been attempted, that discords and dissensions sooner or later arose which invariably resulted in breaking up and separating the company. When a captain has once been chosen, he should be sustained in all his decisions unless he commit some manifest outrage, when a majority of the company can always remove him, and put a more competent man in his place. Sometimes men may be selected who, upon trial, do not come up to the anticipations of those who have placed them in power, and other men will exhibit, during the course of the march, more capacity. Under these circumstances it will not be unwise to make a change, the first election having been distinctly provisional. WAGONS AND TEAMS. A company having been organized, its first interest is to procure a proper outfit of transportation and supplies for the contemplated journey. Wagons should be of the simplest possible construction--strong, light, and made of well-seasoned timber, especially the wheels, as the atmosphere, in the elevated and arid region over which they have to pass, is so exceedingly dry during the summer months that, unless the wood-work is thoroughly seasoned, they will require constant repairs to prevent them from falling to pieces. Wheels made of the bois-d'arc, or Osage orange-wood, are the best for the plains, as they shrink but little, and seldom want repairing. As, however, this wood is not easily procured in the Northern States, white oak answers a very good purpose if well seasoned. Spring wagons made in Concord, New Hampshire, are used to transport passengers and the mails upon some of the routes across the plains, and they are said, by those who have used them, to be much superior to any others. They are made of the close-grained oak that grows in a high northern latitude, and well seasoned. The pole of the wagon should have a joint where it enters the hounds, to prevent the weight from coming upon it and breaking the hounds in passing short and abrupt holes in the road. The perch or coupling-pole should be shifting or movable, as, in the event of the loss of a wheel, an axle, or other accident rendering it necessary to abandon the wagon, a temporary cart may be constructed out of the remaining portion. The tires should be examined just before commencing the journey, and, if not perfectly snug, reset. One of the chief causes of accidents to carriages upon the plains arises from the nuts coming off from the numerous bolts that secure the running gearing. To prevent this, the ends of all the bolts should be riveted; it is seldom necessary to take them off, and when this is required the ends of the bolts may easily be filed away.
