"The maps, four in number, have been plotted upon the large scale of ten miles to the inch; and as every stream, hill, and other accident of ground along the route, and every item of information needful for the emigrant to know- such as where wood, water, and grass can be found; their respective quantities; the several camping places of the troops; their position, distances apart; how unnecessarily long marches can be avoided; how wood and water can be had every night- are minutely laid down upon the map, it is believed that a chart has been prepared which no person of ordinary intelligence can fail to comprehend and make available for all the purposes of a comfortable and successful journey across the plains."
