On the Trail: an Outdoor Book for Girls by Adelia Beard and Lina Beard

For any journey, by rail or by boat, one has a general idea of the direction to be taken, the character of the land or water to be crossed, and of what one will find at the end. So it should be in striking the trail. Learn all you can about the path you are to follow. Whether it is plain or obscure, wet or dry; where it leads; and its length, measured more by time than by actual miles. A smooth, even trail of five miles will not consume the time and strength that must be expended upon a trail of half that length which leads over uneven ground, varied by bogs and obstructed by rocks and fallen trees, or a trail that is all up-hill climbing.

How to Camp Out by John M. Gould

Think over and decide whether you will walk, go horseback, sail, camp out in one place, or what you will do; then learn what you can of the route you propose to go over, or the ground where you intend to camp for the season. If you think of moving through or camping in places unknown to you, it is important to learn whether you can buy provisions and get lodgings along your route. See someone, if you can, who has been where you think of going, and put down in a note-book all he tells you that is important.
