As accidents often occur in camp from the accidental discharge of fire-arms that have been capped, I would recommend that the arms be continually kept loaded in campaigning, but the caps not placed upon the cones until they are required for firing. This will cause but little delay in an action, and will conduce much to security from accidents. When loaded fire-arms have been exposed for any considerable time to a moist atmosphere, they should be discharged, or the cartridges drawn, and the arms thoroughly cleaned, dried, and oiled. Too much attention can not be given in keeping arms in perfect firing order. TRAILING. I know of nothing in the woodman's education of so much importance, or so difficult to acquire, as the art of trailing or tracking men and animals. To become an adept in this art requires the constant practice of years, and with some men a lifetime does not suffice to learn it. Almost all the Indians whom I have met with are proficient in this species of knowledge, the faculty for acquiring which appears to be innate with them. Exigencies of woodland and prairie-life stimulate the savage from childhood to develop faculties so important in the arts of war and of the chase. I have seen very few white men who were good trailers, and practice did not seem very materially to improve their faculties in this regard; they have not the same acute perceptions for these things as the Indian or the Mexican. It is not apprehended that this difficult branch of woodcraft can be taught from books, as it pertains almost exclusively to the school of practice, yet I will give some facts relating to the habits of the Indians that will facilitate its acquirement. A party of Indians, for example, starting out upon a war excursion, leave their families behind, and never transport their lodges; whereas, when they move with their families, they carry their lodges and other effects. If, therefore, an Indian trail is discovered with the marks of the lodge-poles upon it, it has certainly not been made by a war-party; but if the track do not show the trace of lodge-poles, it will be equally certain that a war or hunting party has passed that way, and if it is not desired to come in conflict with them, their direction may be avoided. Mustangs or wild horses, when moving from place to place, leave a trail which is sometimes difficult to distinguish from that made by a mounted party of Indians, especially if the mustangs do not stop to graze. This may be determined by following upon the trail until some dung is found, and if this should lie in a single pile, it is a sure indication that a herd of mustangs has passed, as they always stop to relieve themselves, while a party of Indians would keep their horses in motion, and the ordure would be scattered along the road. If the trail pass through woodland, the mustangs will occasionally go under the limbs of trees too low to admit the passage of a man on horseback.
